Abstract:
A torque-limiting device assembly is provided that includes a bell having a top wall and a circumferential side wall defining a bell interior. A plurality of radially-arrayed engagement grooves are formed on an inner surface of the top wall. A clutch stub shaft having a stem and a plurality of engagement protrusions formed on a clutch flange is disposed within the bell interior. A resilient member is secured to the bell, and the resilient member biases the clutch stub shaft towards the top wall of the bell such that the engagement grooves frictionally engage the engagement protrusions to transfer torque from the stem to the bell when the stem is rotated. An input torque applied to the stem that is greater than a predetermined input torque causes the engagement protrusions to disengage from the engagement grooves such that the input torque is not transferred from the stem to the bell.
