Custom or Modified Standard Worm Gearboxes
Featured Product from Ondrives.US Corporation, formerly Rino Mechanical
ormwheel gearboxes, or worm gearboxes, feature a gear arrangement in which a worm (i.e., a gear in the form of a screw) meshes with a worm gear (similar to a spur gear). Wormwheel gearboxes produce an output that is 90° from the input. A worm gearbox can be used to transmit higher torque or reduce rotational speed.
Most often, a worm gearbox has right hand threads; to change the direction of the output, a left hand thread worm gearbox is required. Worm gearboxes are referred to as 90 degree gearboxes and worm gear reducers.
Ondrives.US designs and manufactures precision right angle worm gearbox systems in ten frames sizes in shaft to bore, hollow bore flange mount, NEMA flange, high ratio, compact, and miniature configurations. Custom worm gearbox systems are also available—contact our application engineers to discuss your custom requirements.
Output torques as high as 420Nm are available. Most of our worm gear reducers are built with ≤30 arc minutes backlash, and can be supplied with as low as ≤4 arc minutes backlash. NOTE: Worm gearboxes should not be used as speed increasers.
