A pulley composed of a polymeric material

摘要

A pulley for a belt drive, such as a toothed-belt pulley, a belt-tensioning pulley, a V-belt pulley or the like, with a support (11) designed as a body of revolution and composed of an electrically non-conductive polymeric material and with a metal body (2), onto the cylindrical curved surface of which the support (11) is pushed by means of a central bore, has a layer (6) of an electrically conductive material forming the contact surface (7) for the belt, this layer being arranged on the circumferential surface of the support (11) and connected to the metal body (2) via an electric conductor (8). <IMAGE>
