Compliant cam of composite materials

Номер: US20120255393A1
Автор: Christopher Corey, Donald Ball, Patrick Waters
Принадлежит: HARRIS CORP

A compliant cam system includes a cam having a cam body rotatable with respect to a cam rotational axis. The cam body has a cam body center spaced from the cam rotational axis. At least a portion of the cam is an elastically compressible material. A follower having at least one follower surface is in contact with the compressible material portion of the cam. A cam non-deflected condition is defined when an elastically compressible material portion outer surface is in contact with the cam follower surface prior to deflection of the elastically compressible material portion. The cam when thereafter rotated with respect to the cam rotational axis moves the cam body center toward the follower. The elastically compressible material portion deflects, defining a deflected condition, creating a biasing force acting toward the follower, and releasably frictionally engaging the elastically compressible material portion with the follower.
