Torque limiting assembly

摘要

A torque limiting device features spring arms that extend resiliently and spirally from a driven member to distal ends rotatably supporting cams that engage cam posts on a drive member to transmit rotation from the drive member to the driven member. In response to a predetermined reactive force, the spring arms are resilient and move radially, and the cams rotate to allow the distal ends to spring past the cam posts in response to a predetermined reactive force.
