Gearboxes are a fundamental component of many drive systems. Effective as speed reducers and in lower ratios, speed increaser gearboxes. The speed reducer gearbox design is used in many applications to increase torque, reduce speed, reverse rotation, and change direction of the driveshaft. Available configurations are Right Angle Worm, Cross Axis Helical, Right Angle Bevel, Parallel Axis, Inline Shaft and Rack & Pinion. Endless combinations of these configurations for our reduction gear boxes are possible and are limited only by system requirements and designer imagination. 

Ondrives.US offers precision speed reduction gearboxes in a range of sizes from miniature to robust. We offer unique, compact, light weight gearboxes in ratios up to 3600:1.  Output torque is available from instrumentation sizes to 850Nm

We offer the widest standard range of gearbox types. Worm & wheel, Crossed Axis Helical, Crossed Axis Worm, Right Angle, Spur Gear, Inline, Servo, NEMA Mount, Miniature, Taper Gear, and Rack & Pinion Gearboxes are always in stock.

Our Engineers have developed a White Paper “10 Points to consider to get the gearbox you need”  to assist you in the selection of the most appropriate speed reducer gearbox for your application.

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

Custom gearboxes can be designed and built to suit your ALL your needs. Contact Ondrives.US Application Engineers to discuss your application.
