ABSTRACT:
A thermoplastic power transmission element having increased torque capacity. A power transmission element, such as a gear, pulley, sheave or sprocket, is formed of a thermoplastic material and includes a central hub arranged to surround and engage a keyed driven shaft. A metallic insert within the central hub engages the key to receive the driving forces transmitted therethrough. The metallic insert includes a plurality of mating surfaces engaging the central hub to distribute the driving forces over an area larger than the area of the keyway. Use of the metallic insert increases the torque capacity of the resulting power transmission element.
