Abstract

A torque limiting device comprises an input shaft, an output shaft and a machined torsion spring having a first end and a second end. The first end and the second end of the torsion spring are coupled to the both the input shaft and the output shaft, whereby torque is transmitted between the input shaft and output shaft via the torsion spring. The couplings between the torsion spring and the input shaft and the output shaft permit limited relative rotation between the input shaft and the output shaft. The device further comprises a jamming mechanism operable in response to relative rotation between the input shaft and output shaft to stop rotation of both the input shaft and the output shaft.
