摘要： A power transmission mechanism has a first rotating member rotating around an axis, a second rotating member rotating around the axis and an elastic member located between the first rotating member and the second rotating member. The first rotating member has a first rotating member surface, and the second rotating member has a second rotating member surface. The elastic member has at least a protrusion contacting at least the first rotating member surface. The protrusion extends in a circumferential direction of the first rotating member. The protrusion has gradually tapering shape toward the first rotating member surface. The elastic member is deformed by compression as the elastic member engages the first rotating member surface and the second rotating member surface by rotation of the first rotating member, thereby causing relative rotation of the first rotating member and the second rotating member.

摘要： A power transmitting mechanism transmits power from an engine to a drive shaft of a compressor. A pulley is supported by the compressor and is coupled to the engine. A hub is attached to the drive shaft. Rollers are located on the pulley. Elastic transmission arms are located between the pulley and the hub. The distal end of each arm is curved, and the proximal end is coupled to the hub. When the rollers are engaged with the arms, power is transmitted between the pulley and the hub. When, due to excessive torque, the rollers escape from the corresponding arm, power transmission between the pulley and the hub is disconnected. The distal ends of the arms are movable in the radial direction. When the rollers disengage from the corresponding arms, the distal ends of the arms move radially such that the pulley and the hub relatively rotate without interference by the arms.

摘要： A power transmission mechanism for power-transmittably coupling a rotating unit of a compressor (11) composed of a drive shaft (17), a rotating support (23) and a swash plate (27) with an engine (62), comprising a pulley (56) and an armature (58), both of which constitute a first rotating body provided on a side of the engine, a hub (57), which serves as a second rotating body coupled to the drive shaft of the compressor, and a helical spring (64), couples the first and second rotating bodies. The use of the helical spring can easily set a resonant frequency of a power transmission system outside a frequency band for troque variation produced on a side of the compressor or the engine. As a result, it becomes possible to suppress resonance of the power transmission system to prevent generation of noises and damage to the internal mechanism of the compressor.

摘要： A power transmission mechanism having a pulley rotor and a release plate. The pulley rotor is coaxial with the release plate, and power from the pulley rotor is transmitted to the release plate to rotate the pulley rotor and the release plate in the same direction. A spiral spring is located between the pulley rotor and the release plate. The spiral spring is releasably engaged with the pulley rotor. A transmission surface is provided on the pulley rotor to oppose and engage a free end of the spiral spring. The transmission surface transfers power from the pulley rotor to the release plate, and relative rotation between the pulley rotor and the release plate is permitted due to deformation of the spiral spring. A release projection causes the free end of the spiral spring to move and separate from the transmission surface in accordance with relative rotation between the pulley rotor and the release plate when the load applied to the release plate exceeds a predetermined value. Therefore, if the release plate applies an unusually strong load to the pulley rotor, it will be released from the pulley rotor.

摘要： A drive power transmission apparatus having an elastically deformable unit formed by combining at least one torque limiting coil spring arranged between a first rotating unit which includes a hub-like plate attached to a drive shaft supported for rotation on a housing of a rotation-receiving unit such as a compressor and a second rotating unit which includes a pulley element driven by a drive power source and supported for rotation on the housing of the rotation-receiving unit via an angular-contact bearing. The elastically deformable unit of the apparatus normally provides an operative interconnection between the first and second rotating units to transmit a drive power from the drive power source to the rotation receiving unit, but disengages one from the other when a load torque produced by the rotation-receiving unit exceeds a predetermined limiting torque in order to interrupt the transmission of the load torque from the rotation-receiving unit to the drive power source.

摘要： A torque limiting mechanism for transmitting power from an external drive source to the drive shat of a compressor. A pulley, which is coupled to the external drive source, has elastic members. A hub, which is attached to the drive shaft, has engaging portions. A coupler member is located between the pulley and the hub. The coupler member is engaged with the elastic members and with the engaging portions such that power is transmitted from the pulley to the hub. The urging members urge the coupler member such that the coupler member is disengaged from the engaging portions. When power is transmitted from the pulley to the hub, the elastic members maintain the coupler engaged with the elastic members and the engaging portions. When load generated due to power transmission exceeds a predetermined level, the elastic members are deformed such that the coupler member is disengaged from the elastic members. When disengaged from the elastic members, the coupler member is disengaged from the engaging portions.

摘要： 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.
