POWER TRANSMITTING DEVICE

Japanese Patent JP3412495

B2

PROBLEM TO BE SOLVED: To provide a power transmitting device with a constitution of good assembly workability without using a rolling ball whereby at overload time, a torque limiter function can be well displayed.
SOLUTION: Mutually among a flange part 11a integrally molded in an inner side holding member 11, washer 13, circular arc-shaped protrusion part 7f in a flange part 7a of a hub 7, and a washer 14, by tension of a belleville spring 15, is friction engaged mutually into contact. In this way, when a compressor 4 is in ordinary operation, rotation of the inner side holding member 11 in a drive side is transmitted to a hub 7 and a rotary shaft 6 through a friction engaging mechanism. On the other hand, at overload time, between the washer 13 and the circular arc-shaped protrusion part 7f in a flange part 7a of the hub 7, which is a friction engaging surface decreasing a coefficient of friction, a slip is generated, by this slip, the washer 13 is dropped to come off in a notched recessed part of the hub 7, to be displaced in an axial direction of the rotary shaft 6, in this way, pressing force of the belleville spring 15 is reduced, the flange part 11a is raced.
