如图3至图5所示，根据本公开的示例性实施例，毂部12的凸缘部11中形成有法兰销孔116，该法兰销孔116用于通过销确定法兰10与涡旋组件20(如图1所示)中的第一涡旋盘21的相对位置。根据本公开的示例性实施例，法兰10通过凸缘部11与第一涡旋盘21连接。具体地，毂部12的凸缘部11中形成有法兰销孔116，第一涡旋盘21的外壁具有涡旋盘连接孔(未标号)，销插入第一涡旋盘21的涡旋盘销孔和法兰10的凸缘部11的法兰销孔116，以确定第一涡旋盘21和法兰10的相对位置。
如图3至图5所示，根据本公开的示例性实施例，毂部12的第二端部128开设有油槽129。具体地，如图2所示，油槽129可以形成在法兰10的毂部12的第二端部128的端面上。油槽129可以沿径向方向延伸。油槽129可以是至少一个油槽，或者按照一定距间(比如等间距)间隔分布的两个或更多个油槽。
根据本公开实施例提供的法兰和包括该法兰的涡旋压缩机，由于在法兰的毂部和凸缘部之间开设凹陷部，可以有效防止涡旋压缩机在高速运行的情况下法兰的轴向变形，不仅改善了涡旋压缩机的可靠性，而且制造成本较低。此外，根据本公开实施例提供的法兰和包括该法兰的涡旋压缩机，由于在法兰的端部表面开设油槽，提高了润滑效果，进而改善了涡旋压缩机的性能。
本领域的技术人员可以理解，上面所描述的实施例都是示例性的，并且本领域的技术人员可以对其进行改进，各种实施例中所描述的结构在不发生结构或者原理方面的冲突的情况下可以进行自由组合。
在详细说明本公开的较佳实施例之后，熟悉本领域的技术人员可清楚地了解，在不脱离随附权利要求的保护范围与精神下可进行各种变化与改变，且本公开亦不受限于说明书中所举示例性实施例的实施方式。
