Method for mounting a bearing assembly on a shaft
View Patent ↗A mounting system is disclosed for mounting a bearing assembly or other mechanical element to a shaft. The mounting system uses a tapered sleeve mechanism to secure the bearing assembly on the shaft. Specifically, a plurality of screws point load the tapered sleeve and drive it from a pre-assembled position to an initial position. Once the initial position has been reached a plurality of fasteners then drive the sleeve from the initial position to a final position. The difference between the initial position and final position determined by the width of a removable spacer used in the mounting system. The system also incorporates a jack screw mechanism used to dismount the bearing assembly from the shaft.
1. A method for mounting a bearing assembly on a shaft, comprising:
engaging a tapered sleeve to a first position between the bearing assembly and the shaft by engagement of a plurality of screws between the sleeve and an external flange, the external flange surrounding the shaft;
removing a removable spacer disposed between the external flange and an internal flange axially secured to the bearing assembly; and
engaging a plurality of fasteners between the external flange and the internal flange to force the sleeve from the first position to a final position.
2. The method of claim 1 , wherein the external flange has a plurality of threaded recesses for receiving the screws, and the sleeve has a plurality of non-threaded recesses disposed to be aligned with the threaded recesses for receiving the screws.
3. The method of claim 1 , comprising limiting engagement of the sleeve when a predetermined torque is applied to the screws.
4. The method of claim 1 , wherein the spacer has a thickness equal to a distance between the first position and the final position.
5. The method of claim 1 , comprising leaving the screws engaged between the sleeve and the external flange to prevent relative rotation of the external flange and sleeve during operation.
