Abstract

본 발명은 스크롤압축기의 선회스크롤 구동장치에 관한 것으로서, 특히 부쉬(320)하단에 일측으로 부터 상부로 일정높이의 밸런스웨이트(6)를 형성하여 보스(310)외주연과 간섭되지 않게한 특징적인 구성에 의해, 모터(3)의 회전수를 가변하여 저속에서 고속까지 넓은 운전범위로 압축기를 운전할 때 원심력이 과도하게 상승하는 선회스크롤의 원심력을 상쇄하여 선회스크롤익과 고정스크롤익간의 접촉력이 무리하게 발생되지 않게 하는 것이다.The present invention relates to a scroll scroll driving device of a scroll compressor, in particular, the balance weight (6) of a certain height from one side to the top of the bushing 320 is formed so as not to interfere with the boss 310 outer periphery With this configuration, the rotational speed of the motor 3 is varied to compensate for the centrifugal force of the turning scroll where the centrifugal force excessively rises when the compressor is operated in a wide operating range from low speed to high speed. It does not happen.

Claims

In engaging the bushing between the boss of the swing scroll and the driving pin of the rotating shaft, a balance weight for generating a proportional centrifugal force in a direction opposite to the centrifugal force due to the revolution of the swing scroll is spaced apart from the boss outer periphery by a predetermined distance from the upper end of the bush. Swivel scroll driving device of a scroll compressor, characterized in that the predetermined height as.

2. The scroll compressor according to claim 1, wherein the balance weight is a hollow semi-cylindrical shape whose inner circumference maintains a constant distance from the outer circumference of the boss and the outer circumference becomes thinner from the center to both ends. Turning scroll drive.
