Abstract
When power is transmitted from a pulley (32) of an engine (E) to a receiving member (35) of a compressor, a power transmitting arm (42) is elastically deformed by force generated by transmission torque. The power transmitting arm (42) thus permits an engaging recess (43) to change its position with respect to the receiving member (35). Accordingly, the pulley (32) and the receiving member (35) are permitted to rotate relative to each other in a predetermined angular range with a roller (39) sliding in the engaging recess (43) while rolling in the engaging recess (43) in a contact state.
Claims15
A power transmission mechanism comprising:
- a first rotary body, wherein the first rotary body has an engaging projection;
- a second rotary body, which is located coaxial with the first rotary body, wherein the second rotary body has an engaging recess;
- the engaging projection engaging with the engaging recess to connect the first and second rotary bodies to each other such that power transmission is permitted;
- at least one of the engaging projection and recess being configured to change its position with respect to the associated rotary body;
- and
- an elastic member, wherein, during the power transmission between the first and second rotary bodies, the elastic member is elastically deformed by force generated by transmission torque for permitting at least one of the engaging projection and recess to change its position, thereby enabling the rotary bodies to rotate relative to each other in a predetermined angular range with the engaging projection sliding in the engaging recess;
- wherein the power transmission mechanism is characterized in that the engaging projection is a rolling component rotationally supported by the first rotary body, and the rolling component slides in the engaging recess while rolling in the engaging recess in a contact state.
