Abstract

Augers used in farm machinery are generally rotatably mounted in a bearing plate. Often the small diameter rotor shaft of the auger becomes fouled by crop material which wraps around the shaft ultimately inhibiting rotation and sometimes damaging rotor bearings. This is avoided by rotatably mounting a larger diameter auger tube within a recess formed in the bearing plate.
