Precision Worm and Wheel Gear Reducers are manufactured by Ondrives.US in 10 frame sizes and with output torques up to 420Nm.

Worm gear reducers are very compact gear systems that produce an output at 90 degrees to the input. The most popular 90 degree gearbox has a right hand thread. To change the direction of the output, left hand thread worm and wheel gearboxes are routinely supplied.

Most Ondrives.US worm gear reducers are built with ≤30 arc minutes backlash and can be supplied with as low as ≤4 arc minutes backlash.

Our engineers have developed a worm gearbox White Paper “10 Points to consider to get the gearbox you need” to assist you in the selection of the most appropriate wormwheel gearboxes for your application.

“Inertia and the use of inertia figures” gives you an example and a formula for dealing with Inertia in gearbox selection.

Speed Increaser: Ondrives.US standard line of WormWheel Gearboxes should NOT be used as speed increasers. Contact Ondrives.US application engineers to discuss your application.

Input and output shafts with drive keys and retainer rings can be supplied to your specifications for any of our hollow bore gearboxes. We carry P Series gearbox output shafts designed specifically for wormwheel gear reducers.
