Shaft mounted bearing for withdrawal over burrs on shaft

摘要

The inner race ring of a bearing is locked to a shaft mounted in the bearing by means of a plurality of set screws spaced circumferentially in an axial end portion of such race ring and each impinging on the shaft to raise a burr on the shaft at the nose of the set screw. So that any burr on the shaft will not interfere with the separation of the shaft and the bearing, a 360 DEG circumferentially extending relief bore is provided on the inside of the inner race ring where the set screws are threadably maintained which has dimensions such that any burr on the shaft is cleared by such relief bore when the shaft and bearing are separated for repair or replacement of the bearing or the shaft.
