摘要： A scroll compressor may include a casing (110) having a sealed inner space; a drive motor (120) provided in the inner space of the casing to generate a rotational force; a rotating shaft (160) coupled to a rotor of drive motor to rotate; an orbiting scroll (150) formed of an aluminum material, and coupled to the rotating shaft to perform an orbiting movement; a fixed scroll (140) coupled to the orbiting scroll to form a compression space consisting of a suction chamber, an intermediate pressure chamber and a discharge chamber; and a rotation prevention member (170) coupled to the orbiting scroll, and formed of a sintered metal. As a result, it may be possible to prevent an Oldham ring from being worn out due to contact with the orbiting scroll. Furthermore, a weight loss portion or wear-resistant coating layer may be formed on a part of the Oldham ring, thereby suppressing a vibration noise of the compressor from being increased due to a weight increase of the Oldham ring.

The first scroll member (76) includes a first end plate (80) and a first spiral wrap (82) extending from the first end plate (80). The second scroll member (78) includes a second end plate (86) and a second spiral wrap (88) extending from the second end plate (86) and intermeshed with the first spiral wrap (82) to define compression pockets (122) therebetween. The first bearing housing (14) supports the first scroll member (76) for rotation about a first rotational axis (A1). The second bearing housing (16) supports the second scroll member (78) for rotation about a second rotational axis (A2) that is parallel to and offset from the first rotational axis (A1). The motor assembly (20) is disposed axially between the first and second bearing housings (14;16) and includes a rotor (100) attached to the first scroll member (76). The rotor (100) surrounds the first and second end plates (80;86).

摘要： A disc-like spacer 78 arranged below a first roller bearing 54 rotatably supporting a driven crankshaft 52 that forms an anti-rotation system 50 is formed with a plurality of notches 78a in the circumferential direction. A spot face 80 is provided to face the outer circumferential surface of the spacer 78, and communication holes 82 and 86 are drilled on the outer circumferential side of the spot face 80 to extend in the axial direction of the scroll. Also formed is a communication hole communicating the communication hole 86 with the first roller bearing 54 via the notches 78a. A grease nipple 88 is mounted to the communication hole 86. To replenish grease, the fixed scroll 10 is removed from the housing 40 such that the orbiting scroll 20 is exposed, and grease is injected from the grease nipple 88 into the first roller bearing 54 with a grease gun.
