Abstract: A belted elevator system (10) includes a hoistway (14) and an elevator car (12) suspended in the hoistway (14) via a suspension member (16) and drivable along the hoistway (14). The suspension member (16) is routed over a plurality of sheaves (18). A sheave (18) of the plurality of sheaves includes a shaft (36) defining a central axis of the sheave (18), the sheave (18) rotatable about the central axis. A sheave outer member (38) is operably connected to the shaft (36) and rotatable about the central axis. The sheave outer member (38) includes a sheave outer surface (44) interactive with the suspension member (16). The sheave outer member (38) is formed from a molded plastic material.

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.

Abstract: A sheave is constructed and arranged to rotate about an axis for guiding motion of a belt. The sheave includes a circumferentially continuous surface facing substantially radially outward. The surface carries a plurality of imprints orientated to prevent belt slip upon the sheave.

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.

Abstract: An elevator system includes one or more rails fixed in a hoistway and an elevator car configured to move through the hoistway along the one or more rails. The system includes one or more braking systems having one more braking surfaces secured to the elevator car and frictionally engageable with one or more rails of the elevator system. One or more actuators are operably connected to the one or more braking surfaces configured to urge engagement and/or disengagement of the one or more braking surfaces with the rail to stop and/or hold the elevator car during operation of the elevator system.
