Abstract:
A disc-like spacer arranged below a first roller bearing rotatably supporting a driven crankshaft that forms an anti-rotation system is formed with a plurality of notches in the circumferential direction. A spot face is provided to face the outer circumferential surface of the spacer, and communication holes and are drilled on the outer circumferential side of the spot face to extend in the axial direction of the scroll. Also formed is a communication hole communicating the communication hole with the first roller bearing via the notches. A grease nipple is mounted to the communication hole. To replenish grease, the fixed scroll is removed from the housing such that the orbiting scroll is exposed, and grease is injected from the grease nipple into the first roller bearing with a grease gun.
