US 4,225,198 A · Bearing mount

Abstract

Accurate torque loading of a bearing (28) mounted in a cavity (34) of a housing (30) is achieved by rotation of an adjusting bolt (50). The bearing (28) is retained within the cavity (34) by means of a bearing race (32) that has one element (32a) engaging a positioning ring (40) and a second element (32b) in contact with a loading washer (44). In surface to surface contact with the loading washer (44) is a driver washer (46) that is positionable within the cavity (34) by means of the adjusting bolt (50). The driver washer (46) is in contact with a positioning ring (42) and by an inward adjustment of the driver washer into the cavity (34) the loading washer (44) is forced against the element (32b) to preload a torque on the bearing (28). Once a specified torque level has been achieved, the adjusting bolt (50) is locked in position by the lock nut (56).

Dependent claims

Apparatus for preloading a bearing having a longitudinal axis, comprising:

a housing having an inner cavity for receiving the bearing;
a bearing race for supporting the bearing in the cavity of said housing:
loading means in contact with the bearing race in the cavity of said housing to preset the force applied to the bearing;
a retainer attached to said housing as an enclosure for the cavity and to position said loading means therein, said retainer including a passage therethrough extending into the cavity;
threaded adjustment means assembled into the passage and engaging said loading means to apply a force against said loading means in a direction transverse to the longitudinal axis of said bearing for positioning said bearing race via the loading washer;
and
wherein said loading means includes a wedged loading washer in contact with said bearing race and a wedged driver washer in contact with said retainer;
and
wherein said retainer includes means for orienting said loading washer in the cavity of said housing.
