Abstract
A method of imprinting a belt sheave without removal of an associated belt includes placing a knurling wheel of a tool against a circumferentially extending section of a sheave not in contact with the belt. The sheave is then rotated to induce rotation of the knurling wheel. A jack screw of the tool is actuated to bias the knurling wheel against the sheave for production of imprints upon the sheave.
Claims11
A method of imprinting a belt sheave without removal of an associated belt frictionally engaged with the belt sheave, the method comprising:
- placing a first knurling wheel of a tool against a circumferentially extending section of the belt sheave not in contact with the belt;
- rotating the belt sheave;
- biasing the first knurling wheel against the belt sheave;
- and
- actuating a jack screw of the tool to bias the first knurling wheel against the belt sheave, thereby inducing rotation of the first knurling wheel by the rotating belt sheave and inducing the production of friction producing imprints upon the belt sheave for increasing friction between the belt and the belt sheave.
