Title:
TORQUE LIMITER
Document Type and Number:
WIPO Patent Application WO/2019/150890
Kind Code:
A1
Abstract:
This torque limiter has a coiled spring fitted over first and second outer peripheral surfaces of coaxially arranged first and second rotation bodies, and the maximum static frictional force between the coiled spring and the first outer peripheral surface and the maximum static frictional force between the coiled spring and the second outer peripheral surface are made different so that, when rotational torque in the direction in which the diameter of the coiled spring increases is applied to the first or second rotation body, if the rotational torque is lower than a predetermined value, the first and second rotation bodies rotate integrally through the coiled spring, and if the rotational torque exceeds the predetermined value, one of the first and second rotation bodies and the coiled spring rotate relative to the other of the first and second rotation bodies.
