Abstract

카운터 웨이트를 구동축 및 구동 부시와는 별개인 구성부품으로 하는 압축기에 있어서, 기동시 및 정지시에 있어서 구동 부시 및 카운터 웨이트와 구동축의 사이에 전달하는 토오크를 안전하게 받쳐준다.In a compressor in which the counterweight is a component separate from the drive shaft and the drive bush, it securely supports the torque transmitted between the drive bush and the counterweight and the drive shaft at startup and stop.

구동 부시와 카운터 웨이트를 상대회전이 불가능하게 결합하고 카운터 웨이트에는 구동축의 큰지름부분 내단(33a)과 유동 가능하게 끼워진 원형상의 카운터 보어를 형성한다. 이 카운터 보어는 카운터 웨이트 및 구동 부시에 대해서 편심핀 둘레의 한정된 조정회전운동을 허용하도록 유동 가능하게 끼울수 있는 간극이 설정되어 있고 카운터 웨이트는 구동 부시와 함께 양 소용돌이체의 상대위치 관계에 생기는 미차를 흡수한다.The drive bush and the counterweight are coupled to each other so that relative rotation is impossible, and the counterweight is formed with a circular counter bore fitted to flow with the inner end 33a of the large diameter portion of the drive shaft. This counter bore has a gap that can be set in a flowable manner to allow a limited adjustment rotational movement around the eccentric pin with respect to the counter weight and the driving bush. Absorb it.

압축기의 기동 및 정지시에는 전달 토오크에 의한 충돌을 수반하는 힘은 카운터 보어와 큰지름부분 내단의 원호면 접촉에 의해 적합하게 받쳐진다.At the start and stop of the compressor, the force accompanying the collision due to the transmission torque is suitably supported by the contact of the counterbore and the arc surface of the inner end of the large diameter part.
