Abstract:
1. A transmission and torque limiting assembly for transmitting rotation from a drive to a compressor, said assembly comprising; a driven member for rotation by the drive about an axis and comprising a hub, a drive member disposed about and coaxial with said driven member, wherein said drive member is a pulley with a planar face, a mechanism for transmitting rotation from said drive member to said driven member and for disengaging said drive member from said driven member in response to a predetermined reactive force between said members, said mechanism including posts axially extending from said planar face, and spring arms integrally formed with said hub and extending resiliently and spirally from said hub, said spring arms including cams pivotally attached to distal ends thereof for engaging said posts for transmitting rotation to said driven member from said drive member, said spring arms resiliently moving radially to allow said cams to release from said posts in response to the predetermined reactive force.
