当压缩机100运行时,参见图1,电机7的转子71通过驱动件3和涡旋盘盖6而驱动第一涡旋盘11旋转,且第一涡旋盘11驱动第二涡旋盘12旋转。待压缩的制冷剂通过压缩机吸入端口106以及支架4和电机罩73所形成的电机外壳的入口94进入电机外壳。一部分制冷剂经过电机7的转子71和定子72之间的间隙流到与压缩机吸入端口106相对的一侧并且另一部分制冷剂通过电机7的定子72和驱动件3的凸缘部32之间的间隙流到与压缩机吸入端口106相对的一侧,以冷却电机。然后制冷剂通过支架4和电机罩73所形成的电机外壳的出口95流出电机外壳。流出电机外壳的制冷剂向上流动,并且通过隔热罩9的盘形部分91与所述涡旋盘盖6的端板61之间的间隙、吸气通道65、形成在所述涡旋盘盖6的端板61与第一涡旋盘11的第一端板112之间的间隙以及所述涡旋盘盖6的筒状部62的内壁与第一涡旋盘11和第二涡旋盘12之间的间隙进入第一涡旋盘11和第二涡旋盘12形成的压缩腔,压缩后的制冷剂通过第一端板112的端口1120,排气件8的内部通道80进入第二空间109,并且然后通 过出口108排出。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55旋转,将容纳在壳体101的底部的油槽中的润滑油通过过滤器155(图47)抽吸到固定轴5的轴向内孔50中,参见图2,部分润滑油进入第二涡旋盘12的毂部121与轴承56之间的间隙以对轴承56进行润滑,进入第二涡旋盘12的毂部121与轴承56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。进入第二涡旋盘12的毂部121与轴承56之间的间隙的部分润滑油通过通孔864(图9)进入轴承58以及绕过轴承56的上端部分进入轴承58,并且部分进入形成在固定轴5中的回油通道862,进入止推轴承54,然后通过固定轴5的表面上的凹部863(图8、图9)、支架4的筒状部41的内壁上的凹部以及贯穿筒状部41的通孔和/或贯穿支架4的凸缘部42的通孔,流到壳体101的底部的油槽中。经过驱动件3的凸缘部32、第一涡旋盘11、第二涡旋盘12等部件的润滑油,通过电机罩73的筒状部732的通道731与支架4的筒状壁43的通道431构成的回油通道,重新流回壳体101的底部的油槽中。可以设置多个回油通道,例如4个回油通道。
根据本发明的实施例的压缩机,通过设置第一油槽和/或第二油槽,当压缩机运行时,润滑油从底部油池通过毂部31的内孔30泵送到止推面,借助于离心力,润滑油从驱动件的止推面的内侧流到止推面的外侧。通过第一油槽和/或第二油槽,可以存储更多的油,以形成油膜,并部分地阻止润滑油流出止推面。
根据本发明的实施例的压缩机,通过在驱动件的环形止推面上设置油槽和/或楔形凸起,改善了在高速下涡旋压缩机的从动涡旋盘与驱动件之间的润滑性能。

根据本发明的实施例的压缩机,可以部分地阻止在高速下润滑油流出止推面。
增加涡旋盘盖以后,由涡旋盘盖、驱动件形成的相对闭合的腔体有助于提高共转压缩机的吸气效率。
增加的电机罩和支架之间形成的通道有利于利用低温制冷剂冷却电机,防止电机过热。
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。
例如,尽管仅仅在图11至图14、图48所示的实施例中示出了楔形凸起36,但是楔形凸起36可以设置在每一个实施例中的驱动件3中。
