Title:
空間楔合摩擦オーバーランニング・クラッチ
Document Type and Number:
Japanese Patent JP2012531562
Kind Code:
A
Abstract:
An overrunning clutch is provided with a spatial wedge-shaped mechanism including a rotation guide mechanism G and a traction friction mechanism F1. The mechanism F 1 has a friction member. A guide member of the mechanism G preferably has a helical tooth guide surface. The rotation guide mechanism G and the traction friction mechanism F 1 are rigidly, axially linked by a common annular intermediate member, which has complementary guide surfaces and a rotation friction surface. The lead angle of the guide surfaces is less than the maximum value of the lead angle which is capable of ensuring self locking of the friction pairs between the guide surfaces, so that the intermediate member can be wedged between the guide member and the friction member, and then transfer torque therebetween. The invention has many advantages such as fully surface contact, a simple structure, no disperse and asymmetry rotation members, and various beneficial operating conditions can be achieved conveniently by the direction controllable scheme.
