Spur Gear Reducer

Spur Gear Design Reducers Ondrives.US Heavy Duty Spur Gear Design Reducers are offered in 6 frame sizes from 24mm D x 46mm W x 58mm H and up to 100mm D x 240mm W x 310mm H. These boxes are available with a shaft input and hollow bore output or they will have a hollow bore on both input and output.

Our spur gear design produces a high efficiency, parallel input and output gearbox. Ratios range from 2:1 to 7:1.  With the available hardened gear units, output torques go to 850Nm.

The housings of these parallel shaft spur gear reducers are precision machined from solid aluminum, producing a lightweight but rugged gearbox. Radial ball bearings are used on both input and output.

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 gearbox 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: Low ratio Spur Gearboxes can be used as speed increasers.
