Abstract

A right angle drive is provided. The right angle drive includes an input shaft, an output shaft, a housing a pair of input shaft bearings and a pair of output shaft bearings. The input shaft carries an input gear for rotation about an input axis. The output shaft carries an output gear for rotation about an output axis. The input and output gears are coupled to transfer rotational motion therebetween. The input and output axis being non-parallel to one another. The pair of input shaft bearings carry the input shaft within the housing for rotation about the input axis. One bearing is on either side of the input gear. The pair of output shaft bearings carry the output shaft within the housing for rotation about the output axis. One bearing is on either side of the input gear. The bearings may interlock with one another.
