<p>PURPOSE:To reduce the cost by attaining the reducing effect of the torque fluctuation of a refrigerant compressor when the load torque is small and the securing effect of the strength of a rubber damper when the excessive torque is applied. CONSTITUTION:Three internal periphery lugs 18 are protruded on the inner periphery side of the cylindrical wall 17 of an outer hub 6, three outer periphery lugs 22 are protruded on the outer periphery side of the cylindrical wall 21 of an inner hub 7, and three rubber dampers 8 having a small torsional spring constant are stuck on cylindrical walls 17, 21 between the inner periphery lugs 18 and the outer periphery lugs 22. When the load torque is small, the inner periphery lugs 18 and the outer periphery lugs 22 are brought into no contact with the rubber dampers 8, and the rotating power is transferred by only the shearing force. When the excessive torque is applied, the rubber dampers 8 are compressed by the inner periphery lugs 18 and the outer periphery lugs 22, the shearing force and the compressive force are applied to the rubber dampers 8, and the torsional spring constant of the rubber dampers 8 is increased.</p> |
