Abstract
A torque limiting device includes a base configured to reside in a fixed position relative to a drive unit, an input shaft assembly configured to receive a torque load from the drive unit, and an output shaft assembly which is capable of rotating about an axis. The torque limiting device further includes detent members disposed adjacent to the input shaft assembly and the output shaft assembly. The detent members are configured to transition the torque limiting device between (i) a drive state in which the input shaft assembly rotates the output shaft assembly about the axis and (ii) a tripped state in which the input shaft assembly does not rotate the output shaft assembly about the axis depending on forces provided to the detent members, by the input shaft assembly, in respective radial directions away from the axis and toward the base.
