Abstract: PROBLEM TO BE SOLVED: To provide a torque limiter capable of responding to high-speed rotation. SOLUTION: The torque limiter is equipped with a differential mechanism 20 connected between an outer ring member 2 and an inner ring 3. The differential mechanism 20 is composed of a first bevel gear 31 which is a first rotation element 21, a second bevel gear 32 which is a second rotation element 22, a differential part intermediate bevel gear 33 which is a differential part intermediate gear 23 engaged with these bevel gears, and a differential rotation element 24 composed of a differential part support shaft 37 and a differential part intermediate shaft 38 integrated to be orthogonal to this and provided with the differential part intermediate bevel gear 33 to be rotatable. The first bevel gear 31 is integrated with the outer ring member 2, and the differential part support shaft 37 is integrated with the inner ring 3, which lowers relative rotation speed of the outer ring member 2 and the inner ring 3 and suppresses heat generation due to friction between a coil spring 4 and the inner ring 3.

Abstract: PROBLEM TO BE SOLVED: To provide a frictional engagement type torque limiter of a specified mechanism employing a coil spring, which makes lubrication failure hardly occur in an initial operation state, or prevents the occurrence of abnormal sounds even though a temperature is high.
SOLUTION: In a torque limiter, an inner ring 2 is provided inside an outer ring 1. A small diameter coil 3a for fastening the outer radial surface of the inner ring 2 is provided at a coil spring 3 incorporated between the inner and outer rings. One of both ends of the coil spring 3 is fixed to the outer ring 1. When the inner ring 2 is frictionally engaged with the coil spring 3 by a fastening force of the coil spring 3, torque can be transmitted between the inner ring 2 and the outer ring 1. While the inner ring 2 is formed of an oil impregnated sintered metal, a predetermined amount of lubricating oil for refilling a shrinkage quantity of a lubricating oil volume after impregnation treatment is applied to the surface of the inner ring 2. The lubricating oil of a refilling lubricating oil volume shrinkage quantity is lubricating oil having viscosity higher than the lubricating oil for impregnation treatment. The torque limiter preferably introduces the lubricating oil of 100 cSt-1,200 cSt.
