Abstract
A compact gear drive assembly for powered equipment includes a housing having a first opening, and an input shaft having a first end located in the housing and a second end extending from the housing through the first opening. The gear drive assembly further includes a first stage gear reduction engaged to and driven by the first end of the input shaft, a second stage gear reduction engaged to and driven by the first stage gear reduction, and an axle engaged to and driven by the second stage gear reduction.
Claims20
A drive assembly, comprising:
- a gear drive comprising a plurality of gears disposed in a housing;
- an input shaft extending into the housing and having a first end engaged to and powering the gear drive, the input shaft having a first axis of rotation;
- an output shaft powered by the gear drive, the output shaft extending out of the housing and having a second axis of rotation that is perpendicular to the first axis of rotation;
- and
- a bushing disposed on the output shaft, the bushing comprising a first end, a second end, a through-bore extending from the first end of the bushing to the second end of the bushing, through which the output shaft extends, an extension and a support slot formed in the extension to support a support shaft for one of the plurality of gears, the support shaft having a longitudinal axis that is perpendicular to the first axis of rotation and the second axis of rotation.

A drive assembly, comprising:
- a housing comprising a main housing member having a first output shaft opening formed therein and a cover fastened to the main housing member, the cover having a second output shaft opening formed therein and at least one tab formed on an internal surface of the cover adjacent to the second output shaft opening;
- a gear drive disposed in the housing and comprising a plurality of gears;
- an input shaft extending into the housing and having a first end engaged to and powering the gear drive, the input shaft having a first axis of rotation;
- an output shaft powered by the gear drive, a first end of the output shaft extending through the first output shaft opening in the main housing member and a second end of the output shaft extending out the second output shaft opening in the cover, the output shaft having a second axis of rotation that is perpendicular to the first axis of rotation;
- and
- a bushing disposed on the output shaft, the bushing comprising at least one anti-rotation slot formed thereon to engage the at least one tab and prevent the bushing from rotating and a support slot formed in an extension of the bushing to support a support shaft for one of the plurality of gears, the support shaft having a longitudinal axis that is perpendicular to the first axis of rotation and the second axis of rotation.
