Abstract
An apparatus for transmitting torque from a motor to a compressor comprises a hub connecting with a compressor shaft and a pulley rotatably supported on the compressor housing, the pulley and the hub connected with one another by a device for vibration clamping and for load limiting and the load limiting is implemented so that the connection between the pulley and hub is discontinued if a specific torque is exceeded. The load limiting device comprises a catch and a limiter ring (b) comprised of metal including pegs directed radially to the center and, through radial form fitting with hub, transmits the torque onto the compressor shaft and catch is made of a synthetic material encasing the limiter ring and catch and limiter ring can be axially displaced on hub and the limiter ring is preferable made of sintered metal.
