ROTATION PREVENTION MECHANISM FOR OSCILLATION PLATE OF OSCILLATING-CAM-PLATE TYPE VARIABLE-CAPACITY COMPRESSOR, AND CONSTANT-VELOCITY FREE COUPLER FOR CONFIGURING SAME

摘要

PROBLEM TO BE SOLVED: To provide a rotation prevention mechanism for an oscillation plate of an oscillating-cam-plate type variable-capacity compressor capable of enhancing quietness and suppressing the manufacturing cost by the reduction of the number of parts and a constang-velocity free coupler constituting the same.;SOLUTION: In the rotation prevention mechanism M for the oscillation plate 43 of the oscillating-cam-plate type variable-capacity compressor 39, the rotation prevention mechanism M for the oscillation plate 43 is formed of a constant-velocity free coupler 70. The constant-velocity free coupler 70 comprises an outer coupling member 73 with an even number of linear track grooves formed on an inner peripheral surface, an inner coupling member 71 with an even number of linear track grooves formed on an outer peripheral surface, and an even number of torque-transmitting balls arranged between pairs of track grooves of the outer coupling member 73 and the inner coupling member 71.;COPYRIGHT: (C)2013,JPO&INPIT
