Torque limiter, corresponding transmission assembly and use

Abstract

A torque limiter including a first body and a second body extending about a central axis. The first body supports first limiter teeth and the second body supports second limiter teeth. The first and second limiter teeth define an engaged configuration and a release configuration. The torque limiter includes limited-retaining means retaining the first and second limiter teeth in the engaged configuration thereof when the torque is less than a transmission torque limit and yielding when the torque exceeds the transmission torque limit. The limited-retaining means include an inner limited-retaining element having an outer contact surface, and an outer limited-retaining element having an inner contact surface mating with the outer contact surface. The inner and outer limited-retaining elements having a retaining configuration wherein the inner limited-retaining element is clamped into the outer limited-retaining element, and a yielded configuration wherein the inner limited-retaining element is loosened from the outer limited-retaining element.
