First Claim
1. A gearbox, comprising:
- an outer housing having a first side wall and a second side wall opposite and spaced apart from said first side wall;
an inner gear assembly received within said outer housing, said inner gear assembly comprising;
an inner housing;
a first gear member rotatably received within said inner housing; and

Abstract
A floating gearbox includes an outer housing with first and second side walls opposite and spaced apart from each other and an inner gear assembly received within the outer housing. The inner gear assembly comprises an inner housing, a first gear member rotatably received within the inner housing, and a second gear member having an output shaft rotatably supported on the inner housing. A slider plate received within the outer housing has first and second pairs of axially aligned elongate openings, wherein the first and second pairs of elongate openings align with a first axis and a second axis, respectively. Pins on the first sidewall are received in the first pair of elongate openings to allow relative sliding movement between the outer housing and the slider plate along the first axis. The inner housing includes pins received in the second pair of elongate openings, allowing relative sliding movement between the inner housing and the slider plate along the second axis.
