The three-part sliding disc Oldham coupling is typically recommended by LinTech for applications that involve high acceleration and the starting and stopping of high inertial loads.
The design and manufacture of customised linear positioning systems on short lead times is key to LinTech's success. This California-based company offers an exceptionally wide range of options enabling its customers to create the optimum system for the job. To compensate for misalignment between the motor shaft and screw (or belt) drive shaft extension LinTech's product programme includes the choice of three different coupling types.
The middle option is especially apposite to LinTech's policy as it too can be tailored to suit the specific needs of the application.
This flexibility is provided by the Oldham Series couplings, which are manufactured and supplied by Huco Dynatork.
This British manufacturer of precision drive products was the first to employ the sliding coupling designed by the 19th century engineer, John Oldham, for locomotive applications.
It introduced a plastic torque disc to achieve zero backlash and applied the principle to modern precision drives.
The Oldham coupling has been central to the Huco product programme since the mid 1980s.
The three-part sliding disc Oldham coupling is typically recommended by LinTech for applications that involve high acceleration and the starting and stopping of high inertial loads.
Naturally it is supplied in a choice of diameter and length sizes and with bore diameters to accommodate various NEMA and metric motor shafts.
However, it is the choice of hub styles and disc materials associated with this coupling that has particular appeal for LinTech.
The hubs determine the method of installation and shaft attachment and the discs, the quality of motion.
The Oldham is precision engineered throughout and comprises two hubs with inward facing tenons.
These engage with matching slots spaced at 90 degrees in a central lightweight torque disc.
As the coupling rotates, the disc compensates for any parallel shaft offset by sliding the commensurate distance along each tenon in turn.
A hard, low friction facing on the working surface guarantees long, trouble-free operation.
Quality of motion is a function of the carefully controlled relationship between the tenons and the torque disc.
The disc is precision moulded from high grade engineering polymers and, being easily replaced at low cost, is the sacrificial element in the drive train.
A choice of torque discs is available including those resistant to radiation and heat.
If severely overloaded the torque disc will break, acting as a mechanical fuse, thereby protecting associated equipment from damage.
A replacement torque disc quickly restores the drive without the need to dismantle the drive system.
'We like the flexibility of mixing and matching different bore hubs to create a total coupling for an application', explains Gary Wester, Vice President of Sales.
'And we favour standard nylon torque disc that provides a nice degree of system damping between the motor output vibrations and the input shaft on our positioning slide'.
This ability to fine-tune the component to the exact performance requirements of the application has earned LinTech a substantial customer base.
Its systems are used in a broad variety of general automation applications but particularly for precise positioning in the medical, automotive and packaging sectors.

Hybrid provides step change in CO2 emissions
The Efficient-C collaborative research project has successfully met the UK Department for Transport's Ultra Low Carbon Car Challenge.
Ricardo, QinetiQ and PSA Peugeot Citroen have revealed the results of the Efficient-C collaborative research project which has successfully met the UK Department for Transport's Ultra Low Carbon Car Challenge. The two year Efficient-C programme has culminated in the delivery of a full-hybrid diesel demonstrator vehicle emitting just 99g/km CO2 (equivalent to 3.75 litre per 100km or over 75 miles per gallon) based on a fully featured Citroen Berlingo Multispace family car. This is a significant leap forward of 30% improvement in fuel economy and CO2 emissions when compared with the equivalent diesel production vehicle.
Furthermore the same diesel hybrid powertrain fitted in a C-segment five-door saloon would only emit 90g tank-to-wheel CO2.
The five-door Euro IV compliant Efficient-C demonstrator meets all the expected performance, comfort and safety levels for today's market and comprises the following integrated technologies: a highly fuel-efficient PSA Peugeot Citroen 1.6 litre HDi, turbo-charged and intercooled common rail diesel engine; a compact 23kW 288V DC electric motor mounted between the engine and the transmission, providing up to 130Nm electrical torque assist, efficient electrical power generation, regenerative braking and full electric vehicle (zero emissions) operation at low speed; a five-speed automated manual transmission delivering cost-effective automatic functionality; and an advanced 288V lithium-ion (Li-ion) battery pack and battery management system to monitor state-of-charge, cell temperature and cell voltage balance.
Supporting systems include a low-temperature cooling circuit to protect the electric motor and power electronics, an electrohydraulic power assisted steering system, electrically powered air conditioning and a touch-screen driver display.
The advanced supervisory control system is based on the Ricardo rCube prototype controller to co-ordinate the many vehicle systems to meet driver demands while optimising fuel economy.
Dave Greenwood, Ricardo Chief Engineer and Efficient-C Project Leader, commented: 'The Efficient-C project has highlighted a range of future technologies which are capable of delivering ultra-low CO2 without compromising vehicle function and performance'.
'The project team is proud to have successfully met the UK Government's Ultra Low Carbon Car Challenge'.
Alain Klein, Director of Hybrid Vehicles Development, at PSA Peugeot Citroen, said: 'We are delighted with the results from this research project which demonstrates the potential for a step change in CO2 emissions reduction with a diesel parallel hybrid'.
'The challenge now is for the motor industry and its suppliers to achieve the cost reductions required for the mass production of diesel hybrids to be considered'.

Wormgear units drop in to upgrade lift drives
When Glasgow City Council urgently needed to repair a lift drive in a residential high rise building it maintains in the city centre, Renold was the ideal answer.
When Glasgow City Council urgently needed to repair a lift drive in a residential high rise building it maintains in the city centre, Renold was the ideal solution. A lift inspector had condemned the original David Brown Radicon units because of excessive backlash which was causing the lift to jolt. Loss of a lift service in a high rise building is obviously an undesirable situation for the residents involved, and so prompt action was required to restore the lift back to working order.
The original plan was to have the Radicon unit repaired; however a chance reading of Renold Gears' 'New for old' direct mailer prompted a call to enquire about the WM Series wormgear units.
The WM Series, manufactured in both metric and imperial distances, is fully interchangeable with competitors' similar sized units, some of which are no longer produced.
The Renold WM units also have the advantage of higher specification gearing and upgraded modern taper roller bearings which give a higher power capacity.
This means that when fitted as a replacement unit it provides a longer life than the original unit.
Glasgow City Council decided to order a number of WM 8in centre units, not only to repair the condemned unit but also to begin the process of rehauling the rest of the ageing lifts in other high rise accommodation.
The units were fitted with special reduced backlash gearing for a smoother lift ride and the external shaft dimensions were manufactured to the exact dimensions of the shaft they replaced.
Fitting exactly into the position of the old units meant no modifications were needed and the lifts could be brought back into service with minimum disruption.
David Giblin, Renold Gears' Sales Engineer, Scotland commented: 'The 8in centre wormgear units were standard in high rise blocks in the late 1960s'.
'The drives are now coming to the end of their lives'.
'The replacement WM Series units are an ideal drop in replacement with the added advantage of increased life'.
To date Renold has received orders for 30 new WM units for lifts in Glasgow.

Couplings combine stiffness with low inertia
Couplings feature zero backlash and even higher torsional stiffness required in today's demanding servomotor applications with high reverse loads and precision positioning requirements.
The latest generation of ServoClass couplings from Zero-Max feature zero backlash and even higher torsional stiffness required in today's demanding servomotor applications with high reverse loads and precision positioning requirements. Manufactured from RoHS compliant materials, and containing no banned substances, the new ServoClass couplings are designed with 304 stainless steel disc packs and 7075-T6 aluminium hubs and centre members. Their design provides high torsional stiffness with low inertia to avoid system resonance in all types of servo systems.
ServoClass couplings handle system speeds up to 10,000rev/min and have a torque rating range from 0.5 to 60Nm.
A system designer can select from 16 sizes and from combinations of inch and metric hub bore sizes to meet exacting servo drive requirements.
All models and sizes feature clamp style mounting hubs with recessed, corrosion resistant clamping bolts.
As the application cycle times become faster, the wind up in beam couplings or the fragile nature of the bellows couplings become more of a serious problem.
The robust design of the Zero-Max ServoClass coupling performs reliably in precision high-speed servo applications.
Zero-Max ServoClass couplings are ideal for use in most high precision applications including packaging machines, pick and place systems, printing machinery, machine tools and most systems using servomotors.
An all new, free eight-page brochure is available that includes complete selection information for ordering and a CD ROM with the Zero-Max ServoClass sizing and selection software included.
The CD ROM gives the designer the ServoClass catalogue in PDF format, a comprehensive sizing and selection program and 3D CAD drawings for all of the couplings.

Right-angle gearhead is a powerful reducer
The SPK+ right-angle gearhead combines the best of two Alpha product families: the top selling SP+ planetary gearhead and the SK+ right-angle gearhead unveiled last year.
In today's world where the intensity of economic change is greater than ever, innovation has become not so much a sought-after key to exclusivity as a simple precondition of a company's survival. Globalisation, copying, volatile raw materials markets and added financial pressures are just a few of the factors which pose a multitude of risks.
At the same time, the rapid pace of development in industry and science generates a steady stream of new innovation opportunities.
For the machine building sector this means new challenges with regard to productivity, end product quality, plant availability and engineering flexibility.
The urgent need for innovation remains unbroken in all these areas, with the design of the machine's drive train frequently playing a vital role.
Since precision and productivity are often constrained by the selected gearhead and motor, improvements to these and other drive components have a significant impact on the machine as a whole - and consequently on their value for users.
SPK+, a new right-angle gearhead for applications with high reduction ratios and torques, is Alpha's response to this trend.
The SPK+ combines the best of two Alpha product families: the top selling SP+ planetary gearhead ('the new generation') and the SK+ right-angle gearhead unveiled last year.
This alliance promises unprecedented performance in an integrated package crammed with practical new features.
The SPK+ is more compact, lighter and more economical than conventional bevel planetary gearboxes, which were never well suited for many important applications.
It achieves higher reduction ratios than other right-angle gearheads with the same number of stages.
Not only is it more powerful, it is also more economical.
In particular, handling tasks - often necessitating a reduction ratio of i=30 to i=40 - now profit from the superior performance of a planetary gearhead from Alpha.
compared with low-backlash worm gearheads, the next smaller size usually suffices.
The output stage assures impeccable positioning accuracy and perfect synchronism - both lasting a lifetime thanks to the fatigue-resisting design of the Alpha hypoid and planetary gearsets.
Its weight is only a third that of low-backlash worm gearheads with similar power transmission - an immense advantage for handling robots and loading/unloading machines with moving drives.
It has a low noise level, courtesy of the smooth-running hypoid gearset on the input and the optimised helical teeth in the SP+.
On the output side, SPK+ is characterised by significantly lower noise emissions than conventional designs.
There are options of i=16 and i=32 for applications like endless positioning, where binary reduction ratios are a must.
A host of solutions featuring SPK+, the SK+ right-angle gearhead, Alpha's high-precision rack-and-pinion system, TK+ and several further products can be implemented for the seventh axis of industrial robots or other additional axes in robotics applications.
cymex 3, the sizing software developed by Alpha, calculates the complete drive unit.
cymex 3, the most advanced servo gear sizing software in the world, has now been extended to include the new SPK+.
It works out all possible solutions to specific drive problems and allows the design to be varied by choosing from thousands of parameter settings.
This enormous versatility is attributable partly to the diversity of the gearhead and accessory solutions (pinions, racks etc) and partly to the fact that cymex 3 also optimises the motor selection process.
The SPK+ comes in four sizes with acceleration torques from 80 to 1100Nm (with 1000 cycles per hour) and 11 reduction ratios from i=12 to i=100.
The torsional backlash is between 2 and 6arc-min, depending on the version (with a deflecting torque equivalent to 2% of T2B).
Thanks to the universal Alpha motor mounting system, all popular servomotor types can be easily mounted.
The gearhead output is compatible with SP+, the de facto industry standard.
And the SPK+ is usually dispatched within one to two weeks.
Technical support and customer service are available worldwide through Alpha's own sales companies and agents.
