Abstract
The present invention aims to provide a cam clutch that enables smooth switching between operation modes while preventing the occurrence of cam engagement, and achieves noise reduction and long service life with a simple structure, without upsizing and increasing the number of components. The above problem is solved by providing a transmission member (161), which comes into contact with each of a first cam (131a) and a second cam (131b) that have different engaging directions, to be rotatable and movable in the axial direction with its rotational center fixed by a cage (140), and by configuring the transmission member (161) such that the transmission member (161) is able to tilt the first cam (131a) when rotated and is able to tilt the second cam (131b) when moved in the axial direction.
Claims6
A cam clutch comprising:
- an outer ring and an inner ring that are provided to be rotatable relative to each other on the same axis;
- a plurality of cams that are arranged between the outer ring and the inner ring;
- and a cage that holds the plurality of cams in a circumferential direction, wherein
- the plurality of cams include a first cam and a second cam that have different engaging directions relative to the outer ring and the inner ring, and are arranged such that the first cam and the second cam form a pair,
- a transmission member that comes into contact with each of the paired first and second cams and is provided to be rotatable and movable in an axial direction with a rotational center thereof fixed by the cage is provided, and
- the transmission member is configured to be able to tilt the first cam between an engaging standby state and a state in which the first cam is not in contact with the outer ring or the inner ring when rotated, and is configured to be able to tilt the second cam between an engaging standby state and a state in which the second cam is not in contact with the outer ring or the inner ring when moved in the axial direction.
