    摘要: Scroll compressor, Oldham ring and a mating component for the scroll compressor.
    The Oldham ring (20) for a scroll compressor (1), comprises: an annular body (21); andone or more keys (22a, 22b, 23a, 23b) protruding from the annular body (21) along an axial direction of the annular body (21), wherein the key (22a) is configured to be engaged with a corresponding sliding slot (16a) of a mating component (10) and has a contact root (33, 34) and a circumferential end surface (31, 32) to be engaged with the sliding slot (16a) whereby at least one of the keys (22a, 22b, 23a, 23b) is provided with a hollow portion (26a, 26a', 26a", 26a"') located at the contact root (33, 34), and an engagement wall (35, 36) with a predetermined stiffness and being elastically deformable is formed between the hollow portion (26a, 26a', 26a", 26a"') and the circumferential end surface (31, 32).

    摘要: 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.

    摘要: A scroll compressor includes: a first scroll (150); a second scroll (160) engaged with the first scroll to form a compression chamber with the first scroll, while performing an orbiting movement; and an Oldham ring (170) including a ring portion (171) formed in a ring shape and a key portion (175) protruding from the ring portion, wherein the key portion is slidably coupled to a key recess (166) provided in the second scroll to enable the second scroll (160) to perform an orbiting movement with respect to the first scroll, wherein a wear preventing member (180) is provided between the key recess (166) of the second scroll (160) and the key portion (175) of the Oldham ring (170).

    摘要: The present invention aims to reduce wear of a key of an Oldham link and a key groove in which the key slides. A scroll compressor (1) includes: a fixed scroll (2), an orbiting scroll (3) revolved relative to the fixed scroll (2); a shaft bearing (6) fixed to a housing (8) and supporting the orbiting scroll (3); and an Oldham link (10) interposed between the orbiting scroll (3) and the shaft bearing (6) and restricting rotation of the orbiting scroll (3). The Oldham link (10) has a first key (11) that slides in a radial direction of a rotating shaft (5) along a wall (21) of a key groove (20) provided in the orbiting scroll (3), and a second key (12) that slides in the radial direction of the rotating shaft (5) along a wall (31) of another key groove (30) provided in the shaft bearing (6). On the assumption of a flat reference surface (210) in the wall (21) of the key groove (20), the wall (21) has an offset portion (21A) that is gradually offset from the reference surface (210) while extending toward at least one of an outer peripheral-side end (20A) and an inner peripheral-side end (20B) of the key groove (20).
