Bearing adjustment system for worm drive has bearings In sleeves with axes at acute angle to centerline of worm so that longitudinal movement of sleeves causes slight lateral movement of worm

摘要

The worm (6) for a worm drive forms part of a shaft with a plain bearing at each end. The ends of the shaft rotate in bores (5) in bushes (4) whose axes coincide with the rotational axis (3) of the worm. The outside diameters of the bushes fit in bores (2) in a drive housing (1). The bores are at the same angle of 1-4 degrees especially 2 degrees to the rotational axis, so that a synchronized longitudinal movement of the bushes gives a small lateral movement of the worm shaft.
