Abstract: Each generic gear includes one tooth disposed in each of the sockets, and each tooth extends radially outward from one of the sockets and throat thereof. The teeth of the generic gear include resilient material adjacent the throat for compressing and allowing movement of each tooth relative to the outer periphery. In the species of FIG. 1, each tooth is entirely of the resilient material and diverges or circumferentially widens from adjacent the throat to define a gap from the throat to the outer periphery. In the species of FIG. 2, each tooth has a shell integral with the hub and a core of the resilient material fills each shell and extends into the socket to define a crescent-shaped gap with the socket end.
