Abstract:
A gear wheel assembly comprising:a gear wheel including a hub having a bore formed therethrough, a web extending about the hub, and a ring gear extending about the web, the web defining a side face, means to reduce noise generated by vibration of the gear wheel, said means comprising at least one disc-shaped vibration damping mass defining a face and a continuous outer annular surface, and coupling means supported on the hub for coupling the vibration damping mass to the web of the gearwheel, wherein the coupling means includes a resilient element that couples the vibration damping mass to the web of the gear wheel such that substantially the full face of the vibration damping mass is in direct contact with a predominant portion of the side face of the web of the gear wheel and the continuous outer annular surface is positioned radially inwardly of the ring gear, and wherein the resilient element causes the vibration damping mass to be forced against the web of the gear wheel with a selected contact pressure.
