Abstract: A scroll compressor according to the present disclosure may include a casing configured to receive a rotation shaft and a driving unit; a compression unit provided with a frame configured to rotatably support the rotation shaft, a first scroll fixed to the casing, and a second scroll configured to be connected to the rotation shaft and engaged with the first scroll; and an oldham ring provided with a plurality of key portions to guide the second scroll to perform an orbiting movement, wherein at least one of the frame, the first and second scrolls includes a key groove formed to receive the key portion; and a wear-resistant member mounted to cover an inner surface of the key groove in contact with the key portion. Due to this, it may possible to easily implement the wear prevention of the oldham ring and components in contact with the oldham ring.

Abstract: A scroll compressor is disclosed. The scroll compressor may include an anti-rotation mechanism provided with an anti-rotation pin (171) and an anti-rotation ring (172) between an orbiting scroll (130) and a scroll support member facing the orbiting scroll, and an axial thickness of the ring body portion (1721) constituting the anti-rotation ring may be larger than an axial depth of a ring insertion groove (1311) in which the anti-rotation ring is inserted. This can allow the orbiting scroll and a member facing the same to be spaced physically apart without a separate member, to secure a gap for oil to flow, such that the oil can be smoothly supplied between the orbiting scroll and the member, thereby suppressing seizure or/and friction loss between the orbiting scroll and the member.
