Moveable shaft assembly

摘要

A moveable shaft assembly including a frame, a first shaft, and a first drive assembly. The frame includes a first support wall and a second support wall opposite the first support wall. The first shaft includes a drive end and a support end and defining a first axis therebetween. The first shaft extends between the first support wall and the second support wall. The first drive assembly rotates the first shaft about the first axis, and the first drive assembly is coupled to the drive end of the first shaft. The first shaft and first drive assembly are moveable relative to the frame in response to a reaction force acting on the first shaft in a direction oblique or transverse to the first axis.
