A controlled start speed reducer in which input and output shafts are axially aligned with one another in an outer housing and an inner housing is journaled in the outer housing coaxially with said shafts. A relatively small bearing is used between said inner and outer housings at one end and a relatively large bearing is disposed between said inner and outer housings at the other end. The inner housing contains a plurality of counter shafts with gears thereon connecting a pinion on the input shaft with a gear on the output shaft to transmit the torque between the two shafts. A disc brake is rigidly connected to the inner housing and rotates therewith, and a caliper head or other suitable element restrains the rotation of the disc to control the starting operation of the reducer. |
