Abstract
A motor direct driven compressor system includes a motor, a coupling and a compressor, and the coupling is coupled between the motor and the compressor, and a second assembling portion, a coupling portion and a metal plate of the coupling are used for connecting a driving shaft of the motor and a transmission shaft of the compressor. With this design, the driving force of the motor can be transmitted to the compressor and provided for the operation of the compressor. In addition, errors produced by the rotation and transmission during the transmission process can be minimized, so that the compressor can be operated accurately and normally.
Claims7
A motor direct driven compressor system, comprising:
- a motor, having a driving shaft installed to a side of the motor, a first cut groove formed at the center of an end of the driving shaft, and a first assembling portion disposed at an external periphery on the same side of the driving shaft;
- an automobile air-conditioning compressor, having a transmission shaft installed to a side of the automobile air-conditioning compressor and opposite to the driving shaft, and a second cut groove formed at the center of an end of the transmission shaft and opposite to the first cut groove;
- a coupling, including a second assembling portion, a coupling portion and a metal plate, wherein the second assembling portion is disposed between the motor and the compressor and assembled with the first assembling portion, and an opening is formed at the center of the second assembling portion, and the coupling portion is disposed between the motor and the second assembling portion, and the coupling portion has a plurality of positioning sections disposed on a side of the coupling portion and separated from each other, and the plurality of positioning sections are disposed around a penetrating hole formed at the center of the coupling portion, and the metal plate is disposed between the motor and the coupling portion, and a side of the metal plate is embedded into the first cut groove of the motor driving shaft, and the compressor transmission shaft is passed through the opening of the second assembling portion and the penetrating hole of the coupling portion, and another side of the metal plate is embedded into the second cut groove of the transmission shaft, and ends of the transmission shaft and the driving shaft are coupled with each other at a position of the metal plate, and external peripheries of the driving shaft and the transmission shaft are coupled to an internal circumferential surface of the plurality of positioning sections.
