Abstract: A compressor may include a shell, a bearing housing supported within the shell, an orbiting scroll, a non-orbiting scroll meshingly engaged with the orbiting scroll, fasteners and a drive shaft. The bearing housing may include a central body defining a bore and arms extending radially outward from a central body and defining circumferentially extending grooves. The circumferentially extending grooves may include inner side walls, outer side walls and base regions extending regionally between the inner and outer side walls and defining fastener receiving apertures. The orbiting scroll may be supported on the bearing housing and a non-orbiting scroll may be meshingly engaged with the orbiting scroll and may include flanges defining flange apertures. The fasteners may extend through the flange apertures and the fasteners receiving apertures and secure the non-orbiting scroll to the bearing housing. The drive shaft may extend through the bore and be engaged with the orbiting scroll.

Abstract translation: 压缩机可以包括壳体，支撑在壳体内的轴承壳体，绕动涡旋盘，与绕动涡盘啮合的非绕动涡旋件，紧固件和驱动轴。 轴承壳体可以包括中心体，其限定孔和从中心体径向向外延伸并限定周向延伸凹槽的臂。 周向延伸的凹槽可以包括内侧壁，外侧壁和基部区域，其在内侧壁和外侧壁之间区域延伸并且限定紧固件接收孔。 绕动涡旋件可以支撑在轴承壳体上，并且非绕动涡旋件可以与定涡旋盘啮合地接合，并且可以包括限定凸缘孔的凸缘。 紧固件可以延伸穿过凸缘孔和紧固件接收孔并将非绕动涡旋件固定到轴承壳体。 驱动轴可以延伸穿过孔并与绕动涡旋件接合。
