New gear systems offer higher strength

The Davall Spiradrive is a right-angled/offset drive, consisting of a gear and pinion. The pinion has fewer teeth than the gear and is of parallel or tapered screw form. The gear is a face type similar to a hypoid-offset spiral bevel.

This arrangement offers a wide range of gear ratios, with a greater number of continuously meshing teeth (than for a worm gear of similar size), resulting in higher strength and smoothness of action from a compact design.

Also, mounting requirements for Spiradrive are not as critical as for bevel or hypoid gears, ensuring maximum accuracy and positive backlash control.

Spiradrive is available in a standard range of gearboxes (motorised and overload protected), loose gear sets, or custom-designed and manufactured to specification.
