METHOD, APPARATUS, AND NUT 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. A system for providing a load on a bearing mounted to a shaft, the system comprising:
a preload apparatus configured to provide a compressive load to the bearing, said preload apparatus releasably connectable to the shaft; a lock nut engageable with the shaft and engageable with a keeper, said keeper having a radially inner side configured to engage the shaft to inhibit rotational movement of said nut relative to the shaft when said radially inner side engages the shaft and said lock nut and said keeper are engaged; and at least one recess in a face of the nut, said at least one recess configured to expose an inner race of the bearing to allow access by said preload apparatus to the bearing to provide a load to the bearing.
