MOTIVE POWER TRANSMISSION DEVICE

摘要

PROBLEM TO BE SOLVED: To reduce noise by restraining vibration of an output disc 8 being a sound generating source. SOLUTION: An outer diameterΦA of an inner hub 22 is formed larger than an inner diameterΦP of a pin part 23. Rigidity of the output disc 8 is enhanced by enlarging the outer diameterΦA of the metallic inner hub 22 up to a part of the resin pin part 23. This constitution can reduce the noise in the vicinity of 1.5 to 2 KHz conventionally generated when turning off a refrigerant compressor being a rotary device by restraining the vibration of the output disc 8. A characteristic of this structure can reduce the noise only by changing the output disc 8 without enlarging the output disc 8 and changing the other part. A torque (rotational) variation by compression work of the refrigerant compressor can be reduced by increasing inertial weight of the inner hub 22. COPYRIGHT: (C)2006,JPO&NCIPI
