Abstract
An assembly for limiting axial motion of a shaft, such as a roller, in an imaging apparatus having a frame, a drive system including a helical drive gear, a shaft supported by the frame and a driven helical gear attached to the shaft and positioned to engage the helical drive gear, wherein driving the driven helical gear in a first rotational direction results in an axial thrust of the shaft in a first axial direction. The assembly includes a thrust member which has an engagement end and a mounting end. The engagement end has a first cross-sectional dimension and the mounting end has a second cross-sectional dimension that is larger than the first cross-sectional dimension. The thrust member is positioned to be co-axial with the shaft and is coupled to at least one of the shaft and the driven helical gear. A thrust bracket is mounted to the frame. The thrust bracket has a contact surface that is engaged by the engagement end of the thrust member when the driven helical gear is driven in the first rotational direction.
