Abstract:
A torque limiting includes first and second rotational plates, first and second springs, and a slip device. The first rotational plate is coupled to a torque input device. The second rotational plate is coupled to a drive shaft, and is configured to be movable along an axial direction thereof. The first spring has a first free length, and exerts a first spring force against the second rotational plate toward the first rotational plate. The second spring has a second free length, smaller than the first free length, and selectively exerts a second spring force against the second rotational plate toward the first rotational plate. The slip device, disposed at least partially within or between the first and second rotational plates, causes relative motion between the first and second rotational plates when torque overcomes the combined first and second spring forces exerted against the second rotational plate.
