Abstract

PURPOSE: To prevent early wear of rope, by chamfering the portion of sheave groove having an undercut where said undercut is formed.
CONSTITUTION: A sheave groove of this invention is formed with an undercut 11 and has an angle 2β of V-shaped groove. This sheave groove has third surfaces 12, 12 at portions thereof where the undercut 11 is formed. The third surface 12 has a radius R of curvature and it is shaped such that it is smoothly continuous with the V-shaped groove and the undercut surface. With such an arrangement, it is avoided that rope elements 2 come into local contact with sheave 1, no matter how rope 2 in a polygonal shape is engaged with the groove 10. Thus, it is enabled to prevent plastic deformation of rope 2 and thus to solve the problem of early breakage of the rope elements.
