摘要:
A torque receiving member (42) is fixed to a rotary shaft (16) of a compressor. A pulley (17), which is rotated by an external drive source (E), is rotatably supported by a housing (11, 12, 13, 14) of the compressor. The pulley (17) is substantially coaxial with the torque receiving member (42). A rubber damper (43) is located between the pulley (17) and the torque receiving member (42). The rubber damper (43) absorbs rotational vibration transmitted from the torque receiving member (42) to the pulley (17). The pulley (17) has a dynamic damper. The dynamic damper includes rollers (46), which swing like pendulums to reduce rotational vibration of the pulley (17). Stress produced due to displacement between the axis of the pulley (17) and the torque receiving member (42) is reduced by the rubber damper (43).

A compressor (C) includes a housing, a rotary shaft (16), a pulley (17), an electric motor (77), a pulley one-way clutch (66), and a motor one-way clutch (83). The shaft (16) is rotatably supported by the housing. The pulley (17) is operably connected to the shaft (16) and includes a power transmission portion. When power is transmitted from a vehicular engine to the power transmission portion, the pulley (16) is rotated. The electric motor (77) rotates the shaft (16) and includes a rotor, which is operably connected to the shaft. At least part of the electric motor (77) overlaps the power transmission portion in the axial direction of the shaft (16). The pulley one-way clutch (66) is located between the pulley (17) and the shaft (16) and selectively permits and prevents power transmission between the pulley (17) and the shaft (16). The motor one-way clutch (83) is located between the rotor and the shaft (16) and selectively permits and prevents power transmission between the rotor and the shaft (16).
摘要:
A rotor is connected to a main body of a rotary machine. The rotor includes a rotor main body (17) and a dynamic damper provided in the rotor main body (17). The rotor main body (17) is made of resin. The dynamic damper has a weight (46) that swings like a pendulum. The axis of the pendulum motion of the weight (46) is separated by a predetermined distance from and is substantially parallel to the rotation axis of the rotor. This suppresses rotational vibration and reduces noise.

A sealed type motor-driven compressor includes a cylindrical motor housing and an annular stator core fastened to the interior of the motor housing. A method of assembling the compressor includes fastening the stator core to the motor housing by mechanically deforming at least one of the motor housing and the stator core. It is thus possible to set the fastening interference between the motor housing and the stator core to a sufficiently great level for suppressing loosening of the stator core with respect to the motor housing, which may otherwise be caused by a relatively high pressure produced by refrigerant gas.

A compressor (100) that employs rollers (43) to suppress resonance. The compressor includes a lug plate (19), which is connected to a rotary drive shaft (16) by means of a rubber damper (19A). The lug plate is arranged in a crank chamber (15). The lug plate has receptacles (41), which guide the pendulum movement of the rollers. When the rotary drive shaft rotates, the pendulum movement of each roller suppresses the resonance of the compressor (100).

A power transmission mechanism transmits power of an external drive source (E) to a rotary shaft (16). The transmission mechanism has a first rotor (17) rotated by the external power source (E). A second rotor (42A) is connected to the rotary shaft (16). The second rotor (42A, 55, 61) is coaxial with the first rotor (17) and coupled to the first rotor (17) transmit power to the first rotor (17). A disconnecting body disconnects power transmission from the first rotor (17) to the second rotor (42A) when an excessive transmission torque is generated between the rotors (17, 42A). A dynamic damper is provided in at least one of the rotors (17, 42A). The dynamic damper has a weight (47, 48) that swings like a pendulum. The axis of the pendulum motion of the weight (47, 48) is separated by a predetermined distance from and is substantially parallel to the rotation axis of the corresponding rotor.
摘要:
A torque limiter (15) is placed between a first rotary body (12) and a second rotary body (35) in a power transmission path. The torque limiter has a breaking portion (34), a flange (31) connected to the first rotary body and a connecting portion (32) protruding from the flange. The connecting portion is screwed to the second rotary body at a predetermined value of fastening torque. The torque is transmitted between the first rotary body and the second rotary body in a relative rotational direction of fastening the connecting portion to the second rotary body. A portion of the flange belongs to the first rotary body after the breaking portion of the flange is broken. The portion of the flange forms a regulating surface (31A) for fastening the connecting portion to the second rotary body. The fastening torque is regulated by a contact on the regulating surface between the flange and the second rotary body.

摘要:
A compressor has a pulley (17) for transmitting torque from an external drive source to a rotary shaft (16) to drive a compression mechanism. The pulley (17) has a pulley body (42). The compressor has a mass body (46) located in a range that is radially inward of the outer circumference of the pulley (17). The mass body (46) swings about an axis that is spaced from the rotation axis of the pulley body (42) by a predetermined distance and is substantially parallel to the rotation axis of the pulley body (42).
