参见图1、图5，在本发明的实施例中，驱动件3的毂部31的第二端部312的端面3120在驱动件3的毂部31的第二端部312和支架4的凸缘部42的环形接触区域上具有油槽56，油槽56从环形接触区域的径向内侧朝向环形接触区域的径向外侧横向延伸而横穿环形接触区域的一部分，油槽56在径向上与环形接触区域的径向外边缘间隔开。油槽56可以沿径向方向延伸。根据本发明的示例，油槽56与驱动件3的毂部31的第二端部312的端面3120的外周边3121间隔开。油槽56也可以形成在支架4的凸缘部42的表面420上。油槽56可以是至少一个油槽，或者按照一定间距(比如等间距)间隔分布的两个或更多个油槽。
参见图1，在本发明的实施例中，电机7可以是轴向磁通电机或径向磁通电机。在一实施例中，电机7包括转子71和固定于支架4的定子72，并且电机7的转子71通过驱动驱动件3旋转而驱动第一涡旋盘11旋转。电机7的转子71设置在定子72的朝向第一方向 D1或第二方向D2的一侧。
参见图1、图2、图4、图6至图10、图14、图15、图27，在本发明的实施例中，驱动件3的凸缘部32与第一涡旋盘11的外壁111密封地连接，以形成涡旋压缩机100的吸入腔88，流体通过吸入腔88进入压缩腔。参见图1、图4、图6至图10、图14、图15，驱动件3包括形成在驱动件3的凸缘部32中的至少一条流体通道6，流体通道6具有形成在驱动件3的凸缘部32的朝向第一方向D1的表面321中的流体入口61，以及形成在驱动件3的凸缘部32的朝向第二方向D2的表面320中的流体出口62，使得流体通过流体通道6的流体入口61，进入流体通道6，并从流体出口62进入吸入腔88。驱动件3可以包括两条流体通道6，两条流体通道6在驱动件3的径向方向上彼此相对。驱动件3的流体通道6可以具有圆形的横截面。根据本发明的一个示例，如图4、图6至图10所示，流体通道6相对于驱动件3的轴向方向倾斜延伸，流体通道6的流体出口62比流体入口61远离驱动件3的旋转轴线91。例如，假设第一平面通过流体通道6的轴线93的在流体入口61处的点和驱动件3的旋转轴线91，而第二平面与第一平面垂直并且与驱动件3的旋转轴线91平行，则流体通道6的轴线93与第一平面的夹角为0至60度，并且流体通道6的轴线93与第二平面的夹角为5至60度。根据本发明的另一个实例，如图14、图15所示，流体通道6沿驱动件3的轴向方向延伸，即流体通道6的轴线93与驱动件3的旋转轴线91平行，流体通道6的轴线93与第一平面的夹角为0度，并且流体通道6的轴线93与第二平面的夹角也为0度。
参见图1、图2，在本发明的实施例中，外壁111具有在与流体通道6的流体出口62的位置对应的位置处的凹部1110，凹部1110形成在外壁111的朝向第一涡旋盘11的旋转轴线的表面1111上，并且凹部1110的朝向第一涡旋盘11的旋转轴线的壁面11101在朝向第一涡旋盘11的第一端板112的方向上逐渐朝向第一涡旋盘11的旋转轴线倾斜或弯曲。
参见图1，在本发明的实施例中，涡旋压缩机100还包括：上油 螺栓81，上油螺栓81容纳于固定轴5的内孔50中，且一端位于壳体101的底部的油池中，另一端与第二涡旋盘12的毂部121固定连接。涡旋压缩机100也可以包括其它任何合适的泵。
当压缩机100运行时，参见图1，电机7通过驱动件3驱动第一涡旋盘11旋转，且第一涡旋盘11驱动第二涡旋盘12旋转。制冷剂通过入口82进入壳体101的第一壳体1011和第二壳体1012形成的密封空间，一部分制冷剂向上流动，绕过筒形挡板83的上端，然后向下流动，通过流体通道6的流体入口61进入流体通道6(参见图4、图6至图8、图10、图14、图15)，另一部分制冷剂向下流动，在筒形挡板83的下端的下方，进入电机7，以冷却电机，然后向上流动，通过流体通道6的流体入口61进入流体通道6。全部制冷剂经由吸入腔88，进入第二涡旋卷124和第一涡旋卷113形成的压缩腔，压缩后的制冷剂通过出口84排出。参见图4、图6至图8、图10，如果流体通道6相对于驱动件3的轴向方向倾斜延伸，则通过流体通道6的流体入口61进入流体通道6的制冷剂由于离心力而经受一级压缩，然后经由吸入腔88，进入第二涡旋卷124和第一涡旋卷113形成的压缩腔而经受二级压缩。同时，第二涡旋盘12带动设置在固定轴5的轴向内孔50中的上油螺栓81旋转，将容纳在壳体101的第一壳体1011底部的油槽中的润滑油抽吸到固定轴5的轴向内孔50中，第一部分润滑油，通过固定轴5上的横向通孔85(例如径向通孔)流到第二轴承52以及驱动件3的毂部31的第二端部312和支架4的凸缘部42(参见图1)之间。第二部分润滑油进入第二涡旋盘12的毂部121与第三轴承53之间的间隙以对第三轴承53进行润滑，进入第二涡旋盘12的毂部121与第三轴承53之间的间隙的一部分润滑油进入第二涡旋盘12的第二端板123与驱动件3的凸缘部32之间的间隙，最后通过流体通道6进入第一涡旋盘11与第二涡旋盘12形成的空间，以对第一涡旋盘11与第二涡旋盘12进行润滑。进入第二涡旋盘12的毂部121与第三轴承53之间的间隙的另一部分润滑油绕过第三轴承53的上端部分进入第一轴承51，并且部分进入形成在固定轴5中的回油通道862，然后通过连通孔89进入形成在固定轴5中 的回油通道861，最后回到在壳体101的第一壳体1011底部的油槽中。进入第一轴承51的润滑油通过横向通孔87(例如径向通孔)进入回油通道862，然后通过连通孔89进入回油通道861，最后回到在壳体101的第一壳体1011底部的油槽中。
采用根据本发明的实施例的用于涡旋压缩机100的驱动件3的套筒9，可以防止第一轴承51和驱动件3之间的接触。驱动件3会因高速旋转而膨胀，此套筒9可固定第一轴承51。
根据本发明的实施例的涡旋压缩机，由于第一涡旋盘和第二涡旋盘各自围绕自己的旋转轴共同旋转，提高了压缩效率。另外，可以采用轴向磁通电动机(例如盘式电机，可以包括定子和转子，定子固定于支架4，转子固定于驱动件)，可以使电机的轴向尺寸更小，由此使压缩机结构更紧凑。此外，由于驱动件的结构设计，可以由驱动件驱动第一涡旋盘旋转，而第一涡旋盘驱动第二涡旋盘旋转，从而可以进一步地将所有轴承都设置在压缩机的同一侧，比如第二涡旋盘的在第一方向D1上的同一侧，从而可以进一步使压缩机结构紧凑。另外，传统共转涡旋压缩机中，往往将轴套过盈安装在旋转件的内孔中，但当涡旋压缩机高速运行时，在离心力的作用下内孔会变大，会减小轴套的附着力从而增加轴套脱落的风险。同时由于轴承与轴配合间隙的存在以及装配的误差，轴套内径与轴的外径接触时会产生局部接触的问题，从而降低轴套的承载。本发明实施例中，通过驱动件的结构设计，以及通过套筒外的突缘设计与驱动件内孔的配合，既能保证轴套与驱动件不会产生相对旋转又能保证不会产生轴承脱落的问题。同时将套筒与驱动件内孔配合的外径加工成圆弧表面，以使轴套内表面均匀接触相配合的轴外径，以提高轴承的承载能力。
尽管描述了上述实施例，但是上述实施例中的一些特征可以进行组合形成新的实施例。
