APPARATUS FOR PRELOADING A BEARING

摘要

Methods and apparatus for preloading a bearing are provided. These methods and apparatus include preload monitoring devices whereby the mechanic can accurately monitor and regulate the preload on a bearing or bearing assembly. Aspects of the invention may also be used to adjust the endplay on a bearing or a bearing assembly. In one aspect, the preload on the bearing is transmitted through a housing having a fluid pressure that can be detected and monitored. An apparatus for precisely rotating a nut and a tool for precisely rotating a nut are also provided. A bearing retaining nut arrangement that permits the loading or evaluating of a bearing inner race is also provided. The bearing retaining nut arrangement includes a first load-setting nut, a lock washer, and a second jam nut that secures the arrangement to a shaft.

主权项

1. An apparatus for providing a preload to a bearing within a wheel hub assembly comprising:
an attaching member attachable to an exposed end of a threaded shaft of an axle or spindle; a frame supporting said member to allow said frame to move relative to said member and in an axial direction; a plurality of extensions extending from said frame towards a wheel hub assembly, said plurality of extensions being configured to contact at least one of a wheel hub or a bearing of said wheel hub assembly when said attaching member is attached to said threaded shaft; and an adjustment mechanism configured to move said frame and said plurality of extensions axially towards said wheel hub assembly to apply a preload to a bearing within said wheel hub assembly.
