Abstract
A plurality of adjacent sheaves are disposed around a common shaft. Each sheave carries a plurality of ball bearings engaged between an inner race of the sheave and the shaft. The ball bearings in one sheave are exposed on one side and bear against an adjacent sheave around the shaft such that friction between a sheave and the shaft and between adjacent sheaves is minimized.
