Bearing adjustment and monitoring system

Abstract

A bearing adjustment and monitoring system is provided for a bearing mounted between a hub and a spindle, one of which is rotatable relative to the other and one of which has a threaded end section with traversing keyway and the other of which has an abutment for limiting inward movement of the bearing. A backing washer member is arranged to removably abut the bearing on the end opposite the abutment and has a key extending into the keyway to secure it against rotation, and a calibrated nut member has threads configured for threading onto the threaded end section. One of the backing washer member and calibrated nut member has a plurality of circumferentially spaced openings and the other of the backing washer member and calibrated nut member has a plurality of openings registering with the openings in the one member but spaced apart differently therefrom, whereby to provide vernier adjustment of rotation of the calibrated nut member. A lock removably secures the backing washer member and calibrated nut member together, and a measuring device operatively interengages the hub and spindle for measuring the relative movement between them for adjusting the axial end play between the hub and spindle.
