Dual lead wormgear sets work either way
Dual lead wormgear sets for positional machinery provide a kinematically correct gear, which can run in either direction of rotation and on which the backlash is infinitely adjustable.
Renold Gears' Holroyd dual lead wormgear sets are ideally suited for use in positional machinery as they provide a kinematically correct gear which can run in either direction of rotation Also, the backlash is infinitely adjustable from an acceptable maximum to zero

Dual lead worm gears work either way
Dual lead worm gear sets are said to be ideally suited for use in positional machinery as they provide a kinematically correct gear, which can run in either direction of rotation.
Shaft mounted helical gear units are in stock
Should production machinery's helical gear unit break down, one can be immediately got from a stock of 12 sizes of belt driven shaft mounted helical gear units.
The gears are manufactured in matched pairs and the mounting diameters are customised.
* Constant gearing contact - Novel transmission testing of the profile of the gears ensures a constant gearing contact throughout its full rotation.
This comprises of a continuous measurement of the angular position of the driven wormwheel relative to where it should be with a perfect gearset as the driving worm rotates at a uniform rate.
The test measures, and records directly, pitch and eccentricity errors, and also the profile errors of the active part of the profile.
* About Renold Gears - Renold Gears has long been known for high quality power transmission equipment, the roots of which can be traced back to the John Holroyd company.
John Holroyd was established, and started manufacture, at the start of the 1900s.
Although the original John Holroyd Company was taken over by Renold in the early sixties, the world renowned quality of the wormgears has remained and today is at the fore front of high precision machine tool wormgears.
Renold Gears' Holroyd dual lead wormgear sets are still manufactured at the same factory in Milnrow, north of Manchester.
Renold Gears supplies precision gears for positional indexing and rotary table drive manufacturers.
