Abstract: This disclosure relates to a gear wheel and method for making the same which is used in an assembly including a flexible motion transmitting core element utilized to transmit motion in a curved path. The gear wheel includes a circular metal wheel comprised of two substantially identical metal halves mated together to define a peripheral groove with helical teeth disposed therein for engaging helical windings on the core element and a plastic hub portion molded partially about the circular metal wheel including an axial bore therethrough for receiving a support member or drive shaft.
