涡旋压缩机
摘要：
本发明的涡旋压缩机抑制十字接头和可动涡旋件的滑动面的烧粘而具有高可靠性。涡旋压缩机(101)具备：可动涡旋件(26)，其具有第一键槽(26d)；壳体(23)，其具有第二键槽(23d)；和可动涡旋件(26)与壳体(23)之间的十字接头(39)。十字接头(39)具有：环状主体部(39a)；两对第一键部(39b)，它们被嵌入到第一键槽(26d)中；和第二键部(39c)，其被嵌入到第二键槽(23d)中。在第一键部(39b)的外周面与第一键槽(26d)的内周面之间形成有键间隙(70)。键间隙(70)具有：十字接头(39)的径向内侧的第一间隙(71)；和径向外侧的第二间隙(72)。由于第二间隙(72)宽于第一间隙(71)，因而能够比第一间隙(71)保持更多量的润滑油。
摘要（英）：

A scroll compressor according to the present invention can suppress seizing at the sliding surface between an Oldham coupling and a movable scroll, and has high reliability. The scroll compressor (101) is equipped with a movable scroll (26) having first key grooves (26d), a housing (23) having second key grooves (23d), and an Oldham coupling (39) between the movable scroll (26) and the housing (23). The Oldham coupling (39) has an annular main body part (39a), two pairs of first key parts (39b) fitted into the first key grooves (26d), and a second key part (39c) fitted into the second key grooves (23d). A key gap (70) is formed between the outer peripheral surface of the first key parts (39b) and the inner peripheral surface of the first key grooves (26d). The key gap (70) has a first gap(71) on the inside in the radial direction of the Oldham coupling (39), and a second gap (72) on the outside in the radial direction. The second gap (72) is wider than the first gap (71), and thus isable to retain a larger amount of lubricating oil than the first gap (71).
