Abstract
In a power transmission apparatus for a compressor according to the present invention, a package of the compressor is reduced in size by shortening the longitudinal length of a one-way bearing while a predetermined level of transmission torque is sustained by optimizing the locations of the one-way bearing and a ball bearing module. Therefore, the mountability thereof can be improved. Also, the one-way bearing is disposed at an outer side from the ball bearing module in a radial direction so as to increase the number of rollers constituting the one-way bearing. Therefore, the transmission torque can be kept identically to that of the related art although the length of the one-way bearing is shortened.
Claims4
A power transmission apparatus for a compressor comprising:
- a pulley rotating by a driving force transmitted from an engine;
- a hub connected to a driving shaft of the compressor which is driven by the engine or a motor and transmitting the rotation force of the pulley to the compressor;
- a power transmission member disposed between the pulley and the hub for transmitting or cutting off the driving power to the compressor selectively;
- and
- a driving shaft connection member for connecting the power transmission member and the driving shaft,
- wherein the driving shaft connection member includes:
- an inner race having a one-way bearing installing portion for disposing a one-way bearing at an outer side thereof and a ball bearing module installing portion for disposing a ball bearing module at an inner side thereof;
- and
- an outer race formed to surround outsides of the one-way bearing and the ball bearing module, and
- wherein the one-way bearing is positioned at an outer side from the ball bearing module installing portion in a radial direction of the driving shaft.
