Torque limiter |
摘要 |
A torque limiter having an outer ring with a plurality of cam surfaces and spring supporting surfaces formed on an inner peripheral surface, an inner member mounted in the outer ring, and a plurality of rollers mounted between the cam surfaces and the inner member. Springs supported on the spring supporting surfaces bias the rollers in a direction to bite into the cam surfaces and the inner member. The springs have a predetermined spring force which is sufficient to maintain the rollers in wedging engagement between the cam surfaces and the inner member when a turning torque for turning the inner member in a direction to urge the rollers out of the wedging engagement is applied to the inner member, but only until the applied torque reaches a predetermined value.
