Title:
TORQUE LIMITER AND METHOD OF RECYCLING SAME
Document Type and Number:
WIPO Patent Application WO/2011/108364
Kind Code:
A1
Abstract:
The weight of a spring type torque limiter is reduced, said spring type torque limiter being such that use is made of a binding force of a coil spring which tightens an inner ring inserted into an outer ring member. This torque limiter is configured in such a way that the coil spring (3), which has a small diameter section (3a) and tightens the outside diameter surface of the inner ring (2) that is rotatably inserted inside the outer ring member (1), is installed in the inner ring (2); that a hook section (3c) at one end of the coil spring (3) is connected to the outer ring member (1); and that a hook section (3d) at the other end is connected to an adjustment ring (4) which is rotatably fitted into the outer ring member (1). In this torque limiter, the inner ring (2) is formed by injection molding of polyacetal, which is a thermoplastic resin. Due to the above, the weight of the inner ring itself and that of the whole torque limiter can be reduced compared with a case where a conventional metal inner ring is used.
