Abstract
Methods and apparatus for preloading a bearing are provided. These methods and apparatus include preload monitoring procedures and devices whereby a 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. The methods and apparatus allow the mechanic to apply and/or verify a preload on the bearing, for example, to apply and/or verify a preferred “3 thousandths” preload, as is desired in the industry. In one aspect, the preload on the bearing is transmitted through a housing having a fluid pressure that can be detected and monitored.
Claims22
1-17. (canceled)
A method for providing a load on a bearing having an inner race mounted to a shaft and the bearing retained on the shaft by a nut, the method comprising:
- mounting a rod to an end of the shaft;
- without removing the nut, mounting a means for compressing the inner race of the bearing to the shaft;
- and
- actuating the means for compressing the inner race to compress the inner race to provide the load to the bearing.
22-38. (canceled)
A method for providing a load on a bearing having an inner race mounted to a shaft and the bearing retained on the shaft by a nut, the method comprising:
- mounting a collar to the shaft:
- mounting a threaded rod to the collar;
- without removing the nut, mounting an adapter, a fluid-containing housing over the adapter, and a nut over the rod,
- wherein the adapter comprises a plate and a plurality of extensions adapted to contact the inner race;
- wherein the fluid-containing housing is positioned to transmit a compressive load from the nut to the adapter;
- and
- wherein the nut is positioned to transmit a load to the fluid-containing housing;
- and
- rotating the nut about the threaded rod to transmit a load to the inner race by means of the fluid-containing housing and the adapter.
