Customised gearbox aids extraterrestrial search
Cone Drive enlisted the help of sister company David Brown to upgrade the shutter motion of the world's largest optical and infra-red telescope.
The second stage of an upgrade project has seen Cone Drive working with Dangel Robots and Machinery to provide another specialist solution for the world famous WM Keck Observatory at the summit of Hawaii's Mauna Kea. Cone Drive had already been involved in a successful project to replace exterior mounted worm boxes in 2004 and this time returned with additional expertise provided by its sister company David Brown to upgrade the shutter motion of the world's largest optical and infra-red telescope. The latest stage of the project involved installation of new drives for the two massive shutters on the dome that encloses the Keck I telescope.
The upper and lower shutters weigh around 47 and 23 tonnes, respectively.
Central drive motors were replaced with synchronised drives on each side of the shutters.
Cone Drive and David Brown - both Textron companies - worked together to provide custom gearbox input and output shafting to match the drive train requirement and simplify the installation which was an onerous task given the telescope's location at 4300m elevation and the requirement to complete the work during a scheduled shutdown.
It was critical to minimise the length of the shutdown required to perform this work in order to avoid losing valuable observing time.
Dangel Robots was engaged to assist with the drive train design and provide the motion control system and software.
The new motion control system incorporates a number of unique features not available previously.
The most significant operational improvements are the ability to use the shutters to track the vertical motion of the telescope to minimise the effect of wind buffeting, and faster shutter speed to close up quickly if the weather turns bad.
Other new capabilities are to move the shutters together with a minimum gap for daytime maintenance, to independently operate the left and right side drives for alignment, and to control shutter speed during portions of the move profile.
For the power transmission, Dangel Robots specified a David Brown G14 right angle bevel-helical gearbox to combine the functions of both the original mitre and helical reduction boxes.
A motor bracket was designed to mount both the motor and the G14 gearbox using some of the existing holes in the shutter frame to ensure the drive train output alignment.
The close working relationship between Cone Drive and David Brown provided custom gearbox input and output shafting to match up the drive train requirement.
This drop-in solution greatly simplified installation on the shutter.
Dangel Robots built a custom enclosure for the motion controller, 40hp inverter drives and drive components to fit inside the curvature of the dome.
Dangel Robots also created a twentieth-scale model of the shutters with 1hp motors to test the motion control electronic components and the software.
The mechanical model and motion control system were interfaced to the Keck telescope operating computer to test all of the motion control functions prior to installation on the actual dome.
Keck Observatory personnel installed the new drive train hardware and control system during a shutdown in the late summer of 2005.
Installation went smoothly and was completed on time.
Shutter motion is faster, smoother and quieter than it was with the old power transmission.
The Keck I telescope is one of two operated by the California Association for Research in Astronomy at the summit of Mauna Kea.
Each telescope stands eight storeys tall and weighs 300 tonnes, yet operates with nanometre precision, probing the deepest regions of the universe.
The dome and shutters for the Keck II telescope were originally built using Cone gearboxes in 1995 and they are still performing today.
Cone Drive provided a 'drop in' solution to replace the reducers on the shutters for the Keck I telescope that was built in 1991.
The original reducers were undersized and causing maintenance problems.
Seal leaks were of special concern because of the low temperatures and dry air at such high altitude.
The observatory presents obvious maintenance problems and the aim was to find a replacement reducer that would require minimum modification at the summit, and which offered an increased service factor and improved seal arrangement.
For the final stage of the project four David Brown G14 gearboxes with a ratio of 41.6:1 were added to the 14 previously installed Cone custom 8.000in centre distance HP double enveloping worm reducer units with a special ratio of 9.75:1.
Modified shafting, housings, mounting flanges and keeper plates were provided to mount the gearboxes and connect them together.
The gearboxes incorporate taconite seal arrangements on both input and output shafts.
Oil expansion chambers were supplied to provide sealed units since the gearboxes change attitude as the shutters move up and down over the dome.

Gearboxes drop in for speedy upgrade
Tarmac's Buxton Lime Quarry has replaced the gearboxes on its wash drums with the minimum of modification, thereby speeding up the installation and limiting production downtime.
A recent order for David Brown Series G units has enabled Tarmac's Buxton Lime Quarry to replace the gearboxes on its No 3 wash drums with the minimum of modification, thereby speeding up the installation and limiting production downtime. A combination of ready product availability and expert technical assistance from David Brown gave the quarry the confidence to undertake the important work with a minimum of disturbance. As a trusted supplier to the quarry over the years - more than 100 David Brown gearboxes are currently operating on the site - David Brown was approached to suggest possible replacements for existing gearboxes manufactured by a competitor and put forward its Series G as the best solution.
Aiming to get as close as possible to a 'drop-in' solution, David Brown's sales team liaised closely with the quarry, inspecting the installation and providing detailed drawings and advice necessary to enable the work to be carried out.
The standard gearboxes were customised to feature specially-shortened output shafts and needed only redrilling of the base plate and the use of packing plates to raise the shaft centres to the correct height.
The installation work took a total of 16 hours, and a further gearbox is being kept on site as a strategic spare.
The twin wash drums, motors and drives, which process a total of 2.5 million tonnes of material per annum, were supplied some years ago as a package and came already fitted with a competitor's gearboxes.
As these gearboxes approached the end of their working lives a quote was obtained for their substitution on a 'like-for-like' basis but by this stage the model had gone out of normal production and was prohibitively expensive, with a significant delay in availability, and an 'equivalent' product in the competitor's range would have required too much modification to be practical - hence the attraction of the David Brown solution.
The washing plant at Tarmac's Buxton Lime Plant produces hydrated limes used for a soda ash process in Cheshire and for flue gas desulphurisation at three power stations in the East Midlands.
Series G gearboxes are offered in seven sizes from 11 to 130kNm output torque, with a ratio coverage of 6:3:1 to 315:1.
Designed to meet the requirements of applications including bulk handling, mixing, water treatment, cooling towers and conveyor drives, Series G units can be specified in parallel shaft helical and right angle shaft bevel/helical units in double, triple and quadruple reduction gear stages.
Modular design and construction, a high degree of interchangeability of parts and subassemblies, and a universally machined, horizontally split casing has created a family of speed reducing gear units that can be quickly manufactured and is simple to maintain with significant delivery and cost benefits for customers.
The innovative modular construction of the inherently reliable Series G units minimises part count to maximise availability of product.
Fewer than 160 major components meet 10,000 drive solutions.
In many cases units can be ordered and delivered within days compared with a typical schedule of over 6 weeks for a comparable competitor unit.
This not only produces a radical reduction in potential down-time of vital plant, but also enables end-users to reduce stock levels.
Strength and efficiency are maximised, while noise and vibration are kept to a minimum by case hardened and ground helical gears, and hard finished spiral bevel gears.
For extended, efficient life, oil is kept where it belongs by the patented end cover, which improves bearing lubrication and allows a 30% improvement in thermal capacity.

Gearboxes drop in to upgrade mill capacity
David Brown Engineering has supplied five large gearboxes and pinions to JSW Steel in India in the first stage of a major upgrading of the company's hot strip mill facilities completed during April and May 2006. This initial project will increase capacity by 40% and other planned improvements are designed to progressively double throughput at the facilities. The plant near Bellary in the province of Karnataka has six finishing mills with 5000hp motors and these motors have been upgraded to 7000hp.
The replacement gearboxes and pinions from David Brown Engineering have the same footprint and critical dimensions as the existing ones, enabling a 'drop-in' solution.
This caused the minimum disruption to production when they were installed together with new motors as well as obviating the main obstacle to upgrading given that reorganisation of the mill equipment layout invariably involves monumental cost and long term disruption.
Close co-operation between JSW Steel and David Brown and all the partners in the project has been the hallmark of the operation and experts from the engineering company made a number of visits to the plant to discuss the project, offer technical advise, take measurements and work in conjunction with other major suppliers who were involved in motors and couplings and in overall consultancy.
In fact representatives of David Brown Engineering visited the plant to take measurements and plan for the project five times in conjunction with the other three partners in the project: main contractor VAI (UK), motor manufacturer Siemens, Germany and couplings producer Maina, Italy.
A good example of the spirit of co-operation that characterises the project was the fitting of couplings before dispatch of the gearboxes from Huddersfield.
In the original plan the Italian-built Maina couplings would have been fitted on site in India, but it was judged that critical installation time could be reduced on site by first shipping the couplings to the UK.
Furthermore David Brown Engineering supplied services of commissioning engineering, flying out to India to supervise the installation of the gearboxes, and in the run-up to the operation team meetings are being held at VAI offices in Sheffield.
The installation took place in one planned 5 week shutdown with the actual installation performed by JSW Steel.
VAI and Siemens were also present to oversee the installation of the motors.
The existing plant was purchased in its entirety from the United States a decade ago and the gearboxes were reaching the end of their natural life.
The plant, in the remote province of Karnataka in southern India, is part of the JSW Group, in turn part of India's fourth largest business conglomerate, the Jindal Organisation with interests in mining, carbon steel, stainless steel, power and oxygen and currently valued at US $4 billion.
The group was founded in 1964 by OP Jindal who from humble beginnings, rose to become one of India's leading industrialists and founded a steel making dynasty of world importance.
This particular step in investment and expansion is seen as a major opportunity for the group against the current backdrop of a world steel shortage.

On-site services solve tricky problems
Manoeuvring a 3m-diameter 23t gear for Blue Circle Southern in Australia is just one example of the resourcefulness regularly shown by David Brown's on-site services team.Overcoming extremely limited clearances while manoeuvring a 3m-diameter 23t gear for Blue Circle Southern in Australia is just one example of the resourcefulness regularly shown by David Brown's on-site services team. In this case a special cradle was constructed under David Brown's guidance and the gear was transferred into place on rails. The cement mill gearbox operated by Australia's major cement producer had suffered a bearing failure and the resulting debris caused significant damage to the slow speed dual drive double helical pinions and gear teeth.
Engineers from David Brown attended the site to make repairs and allow continued production, at a reduced rate of 75% of full capacity, while the replacement gear and pinions could be manufactured by David Brown Australia.
In the interim there was close liaison with the client to plan the gear set replacement method and keep downtime to a minimum.
Production resumed at 100% following installation of the new gear set in 2004.
An inspection carried out in 2005, following 12 months of full production, showed exceptional tooth contact patterns and an absence of tooth wear, giving the overall refurbishment project a double 'thumbs up'.
The contract underlines the scope of David Brown's on-site services in a market which is increasingly driven by service as well as product excellence.
The team that worked on the project is just part of David Brown's fully qualified field service engineer resource which is available in most key geographies to provide a number of key services from performance testing, fault diagnostics through to installation/commissioning, alignment checks and emergency repairs.
Recognising the importance of preventative maintenance, the company also boasts a range of applications knowledge, gained through close long-term customer partnerships in many heavy process industries, to offer performance improvements to transmissions and other rotating equipment.
Using appropriate condition monitoring and analysis techniques, David Brown is able to pin point critical process issues and recommend courses of action to substantially reduce the associated risks.
David Brown's deep knowledge of transmissions and other rotating equipment, combined with its close geographic proximity, means it is well positioned to respond rapidly to its customers' needs, seeking to identify and predict issues, and offering solutions to improve their process performance.
Service engineers are also available to install and inspect transmissions and other rotating equipment throughout the world and David Brown provides installation services and alignment checks that cover everything from a simple equipment installation to a complete drive system installation.
To ensure a proper startup of the equipment, David Brown service engineers can also provide its customers with inspection services and advice on project managing installations.
Finally, experienced service engineers, using modern equipment and leading technology, provide repair services at the site to restore or enhance performance of transmissions or other rotating equipment.
The services range from emergency repairs, as in Australia, to repairs of equipment during planned shutdowns.

Universal joints need no tools for maintenance
Abssac continues to expand its rotary product portfolio by teaming up with Curtis Universal of the USA and its unique range of Curtis TakeApart universal joints. Universal joint applications by design normally require two shafts not in line with each other limited freedom of movement in any direction while transmitting rotary motion. Where Curtis excels is in the design and assistance developing a universal joint application to achieve a cost effective transmission solution, applying more than 75 years of universal joint experience.
The company can incorporate different types of end attachment as well as allowing telescopic action during rotation into the design.
The universal joints are machined, not cast, which enables high tensile strength and outstanding reliability but also lends itself perfectly for unique transmission designs.
As standard all universal joints are available in alloy steel, stainless steel, however many applications have been developed using nonstandard materials such as titanium and Monel alloys.
We are also familiar with dealing with different heat and surface treatments to achieve a desired hardness or corrosion resistance.
The basic universal joint uses a single joint configuration which can accept up to 35 degrees of angular misalignment.
Where more angular flexibility is required, the double joint design can accept up to 70 degrees of shaft misalignment.
For applications such as marine, which require unusually high noncorrosion standards, Curtis can supply universal joints in stainless steel, bronze, naval brass, aluminium-bronze, nickel-aluminium-bronze and Monel alloy.
Uniquely, the standard ranges can incorporate the Curtis TakeApart design, which allows the disassembly and reassembly of the universal joint without the use of special tools and replacement of component parts.
This feature enables the end user to machine the hubs to fit the mating shaft if a standard bore does not.
In addition to this, easier access to other components in a drive line can be achieved by being able to quickly and easily disassemble the joint after it has been installed in the application.

Formed in 2005 to distribute Reliance's standard product range, Reliance Precision Mechatronics offers small quantities at stock prices for cost effective prototype development.
To complete the customer service package the company can also: predict the performance of its standard components in a customer's application; specify associated components for a customer's design; modify standard components to suit a customer's requirements; and offer unique solutions from proven concepts.
A team of dedicated mechatronic design engineers is on hand to support customer design requirements and develop turnkey mechatronic solutions.
Reliance Precision offers in-house design, manufacture, assembly and test all under one roof.
With dedicated manufacturing facilities the company can supply production quantities of customised components and, in many cases, provide full assembly support to its customers including: design for manufacture; weight critical design and analysis; safety critical design and analysis; prototype manufacture; life validation testing; and repair service and obsolescence management.
Quality assured to BS EN ISO9001:2000 and the aerospace standard AS 9100 Revision B, Reliance is committed to providing the highest quality in terms of both manufacture and service.
Reliance is certified to the environmental management standard BS EN ISO14001:2004
Bore reducers come in brass and aluminium
Brass and aluminium bore reducers are designed to fit into couplings where smaller bores are required quickly and easily.
Ondrives offers a range of brass and aluminium bore reducers designed to fit into couplings where smaller bores are required quickly and easily.
They start from 5mm O/D and go up to 28mm O/D, the smallest bore available being 2mm in brass and the largest 25.4mm in aluminium.
It should be noted that both concentricity and traction may be affected when using a bore reducer, so customers are advised to check their application carefully before use.

Bevel gearboxes offer many options
A miniature instrument bevel tee gearbox is available in a 1:1 ratio and comes with either steel or plastic gears as standard.
A wide variety of in-house UK produced gearboxes are offered by Ondrives of Chesterfield. One of the most popular ranges are the bevel gearboxes as they are available in many different configurations. One of the types is the miniature instrument bevel tee version which is available in a 1:1 ratio and comes with either steel or plastic gears as standard.
It is called miniature because it is only 30.5mm x 30.5mm wide.
Other gearboxes in the bevel collection range from right angled drive types, hardened teeth or hardened bevel versions, bore input or bore output only, bore input and output, heavy duty, counter rotating output, high bevel reduction and spiral bevel value boxes.
Ratios range from 1:1 to 24:1 dependant on the type of gearbox chosen.
Specials can be made according to customer's specifications and all are drawn out using the latest 3D CAD technology systems.
CAD drawings can be downloaded from the Ondrives website for all standard bevel boxes.
