Title:
BIDIRECTRIONAL TORQUE LIMITER
Document Type and Number:
Japanese Patent JP2002155973
Kind Code:
A
Abstract:

To provide a bidirectional torque limiter having different adjustable torque values in normal rotation and reverse rotation.

An outer ring 1, an inner ring 2, and a side ring 3 are concentrically arranged so as to rotate each other. The bidirectional torque limiter 10 is so structured that a shield 7 journals the side ring 3 and closes an end of the outer ring 1. A coil spring 4 winded in an outer periphery of the inner ring 2 so as to tighten and fit, and a coil spring 5 winded in the same direction as the coil spring 4 and pressed into an inner periphery of the inner ring 2 are arranged. A projection 44 is formed on an end part of the coil spring 4 and is latched to the outer ring 1 to determine a torque value in a normal direction. A projection 55 is formed on an end part of the coil spring 5 and is latched to the side ring 3 to determine a torque value in a reverse direction.
