Abstract
A sheave knurling tool is adapted to knurl a sheave while carrying a belt and coupled to a drive unit for rotation. The sheave knurling tool may include a body, an arm, a jack, and a knurling wheel. The body is detachably coupled to a support structure of the drive unit. The arm is pivotally engaged to the body about a pivot axis. The jack is adjustably coupled to, and extends between, the body and the arm. The knurling wheel is carried by the arm, and the jack is constructed and arranged to pivot the arm toward the sheave thereby exerting a biasing force of the knurling wheel against the sheave.

A sheave knurling tool adapted to knurl a sheave while carrying a belt and while coupled to a drive unit for rotation, the sheave knurling tool comprising:
- a body detachably coupled to a support structure of the drive unit;
- an arm pivotally engaged to the body about a first pivot axis;
- a jack adjustably coupled to and extending between the body and the arm;
- and
- a first knurling wheel carried by the arm, and wherein the jack is constructed and arranged to pivot the arm toward the sheave thereby exerting a biasing force of the first knurling wheel against the sheave.
A method of operating a sheave knurling tool comprising:
- placing the sheave knurling tool between two belt segments draping down from a sheave;
- mounting a body to a support structure of a drive unit coupled to the sheave;
- actuating a jack to move an arm pivotally engaged to the body;
- and
- bearing a knurling wheel coupled to the arm against an exposed surface section of a circumferentially continuous surface of the sheave.
