参见图1和图1A，在本发明的实施例中，涡旋压缩机100还包括：固定轴5，固定轴5的下端固定于支架4。通过驱动件3的毂部31可转动地安装在固定轴5上使驱动件3可转动地安装于支架4。第二涡旋盘12的第二端板123被可转动地支撑在驱动件3的凸缘部32上。
参见图1和图1A，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。在一些实施例中，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。
参见图2至图4、图6至图17、图19至图22、图25至图30，根据本发明的实施例的驱动件3包括：具有内孔30的毂部31，所述毂部31包括相对的第一端部311和第二端部312；以及在所述毂部31的径向方向上从所述毂部31的第一端部311向外伸出的凸缘部32，所述凸缘部32具有朝向从第一端部311到第二端部312的方向的表面321，所述凸缘部32的所述表面321具有环形止推面3210和油槽。
参见图6至图17、图26至图30，在本发明的实施例中，所述油槽包括：在所述凸缘部32的所述表面321的环形止推面3210上的第一油槽331，所述第一油槽331在从环形止推面3210的径向内侧朝向环形止推面3210的径向外侧的方向上横向延伸而横穿所述环形止推面3210的一部分，所述第一油槽331在所述毂部31的径向方向上与环形止推面3210的径向外边缘3211间隔开。所述第一油槽331可以沿径向方向延伸或沿与径向方向成锐角的方向延伸。根据本发明 的示例，所述第一油槽331从环形止推面3210的径向内边缘3212延伸。所述第一油槽331也可以从其它位置延伸，例如该位置在径向上距离环形止推面3210的径向内边缘3212一定距离。在图中所示的实施例中，所述环形止推面3210在所述毂部31的径向方向上从毂部31的内孔30的边缘300开始延伸。例如，所述第一油槽331从所述毂部31的内孔30的边缘300朝向环形止推面3210的径向外侧延伸，并与所述内孔30连通。所述环形止推面3210也可以在所述毂部31的径向方向上从其它位置开始延伸，例如该位置在径向上距离毂部31的内孔30的边缘300一定距离。在本发明的实施例中，所述第一油槽331可以是至少一个油槽，或者按照一定间距(比如等间距)在周向方向上间隔分布的两个或更多个油槽。通过在止推面上设置第一油槽，即使压缩机高速运行，第一油槽也可以储存润滑油并且向驱动件与第二涡旋盘的摩擦副供应润滑油。
参见图9至图17、图19至图22、图27至图30，在本发明的实施例中，所述油槽还包括：在所述凸缘部32的所述表面321的环形止推面3210的径向外侧设置在所述凸缘部32的所述表面321上的第二油槽332，所述第二油槽332围绕所述环形止推面3210延伸。参见图9至图17、图27至图30，在本发明的实施例中，所述第二油槽332的深度大于所述第一油槽331的深度。第二油槽332可以储存润滑油，并且可以在径向上防止润滑油由于离心力从第一油槽直接流出止推面。
参见图9至图11、图15至图17、图19至图22、图27、图29、图30，在本发明的实施例中，所述第二油槽332是闭合的环状油槽。参见图15至图18、图22、图23，在本发明的实施例中，驱动件3还包括：设置在所述第二油槽332中的挡圈35。参见图17和图18，所述挡圈35可以具有矩形的横截面或正方形的横截面，挡圈35可以是实心的。在图22至图24所示的实施例中，所述挡圈35具有C形的横截面，所述挡圈35具有开口351，所述开口351朝向驱动件3的旋转轴线，挡圈的外部可以是由耐磨材料(例如特氟龙材料)制成的C形部分352，内部设有弹簧353作为支撑结构。换句话说，在图 9至图11、图19至图21所示的驱动件3的第二油槽332中可以分别放置图18和图23所示的挡圈35。挡圈可以阻挡一部分润滑油沿径向流出驱动件与第二涡旋盘的接触区域。
参见图2至图4、图6至图17、图19至图22、图25至图30，驱动件3还包括：在所述凸缘部32的所述表面321中的偏心环孔326。驱动件3可以具有三个偏心环孔326。在图9至图11、图15至图17、图27所示的实施例中，所述第二油槽332的与偏心环孔326对应的部分位于偏心环孔326的在所述毂部31的径向方向上的内侧。在图12至图14、图28所示的实施例中，所述第二油槽332包括多个第二油槽段3320，所述多个第二油槽段3320中的每一个位于相邻的偏心环孔326之间并且所述多个第二油槽段3320中的每一个的端部3321与偏心环孔326连通，所述第二油槽332可以沿圆延伸，所述圆的圆心在驱动件3的旋转轴线上。在图19至图22、图29至图30所示的实施例中，所述驱动件3还包括：在所述凸缘部32的所述表面321的环形止推面3210的径向外侧设置在所述凸缘部32的所述表面321上的环状的第二油槽332，所述第二油槽332可以沿圆延伸，所述圆的圆心在驱动件3的旋转轴线上，所述第二油槽332的与偏心环孔326对应的部分位于偏心环孔326的在所述毂部31的径向方向上的外侧。在图19至图22所示的实施例中，去掉了第一油槽331，仅仅保留了第二油槽。
参见图2、图3、图6、图7、图9、图10、图12、图13、图15、图16、图25至图30，在本发明的一些实施例中，所述驱动件3还包括：贯穿所述凸缘部32并且在所述凸缘部32的所述表面321的环形止推面3210的径向外侧的排油孔325。参见图19、图20，在本发明的另一些实施例中，所述驱动件3还包括排油孔325，排油孔325贯穿所述凸缘部32并且排油孔325在环形止推面3210的邻近径向外侧的部分。在图中所示的实施例中，驱动件3包括三个排油孔325。排油孔325可以是任何合适的数量的排油孔325。当润滑油流到止推面的末端时，润滑油会流入排油孔，并最终流回底部油池中。
参见图2至图5、图25，在本发明的一些实施例中，所述驱动 件3还包括：从所述凸缘部32的所述表面321的环形止推面3210突起的环状的楔形凸起36，所述楔形凸起36在径向方向上的横截面具有楔形形状，所述楔形凸起36具有楔形凸起表面360，在径向方向上的横截面中，所述楔形凸起表面360在径向方向上的第一楔形凸起点361与所述凸缘部32的所述表面321的轴向距离最大，并且所述楔形凸起表面360在径向方向上的第二楔形凸起点362与所述凸缘部32的所述表面321的轴向距离为零。所述第一楔形凸起点361可以在第二楔形凸起点362的径向外侧或径向内侧。在图中所示的实施例中，所述第二楔形凸起点362位于所述毂部31的内孔30的边缘300。所述第二楔形凸起点362也可以在径向方向上与所述毂部31的内孔30的边缘300距离一定距离。在第一楔形凸起点361，所述楔形凸起表面360与所述凸缘部32的所述表面321的轴向距离在0.1微米至1毫米的范围内。在图2至图5所示的实施例中，表面321的环形止推面3210设有环状的楔形凸起36，但是没有设置第一油槽331和第二油槽332，而在图19至图24所示的实施例中，表面321的环形止推面3210设有环状的楔形凸起36和第二油槽332，但是没有设置第一油槽331。此外，对于楔形凸起36、第一油槽331和第二油槽332，表面321可以设置三者中的至少一个，例如，表面321的环形止推面3210可以仅仅设置第一油槽331，表面321可以仅仅设置第二油槽332，或者可以仅仅设置第一油槽331和第二油槽332。通过在止推面上设置楔形凸起，有利于在第二涡旋盘与驱动件之间形成油膜。
参见图1、图2、图3、图6、图7、图9、图10、图12、图13、图15、图16、图19、图20、图25至图30，在本发明的实施例中，驱动件3的凸缘部32具有驱动件连接孔323，驱动件3的凸缘部32的驱动件连接孔323具有螺纹部，如图1所示，通过螺栓和驱动件连接孔323的螺纹部的螺纹连接，涡旋盘盖6与驱动件3的凸缘部32固定连接，而涡旋盘盖6还通过螺栓与第一涡旋盘11连接，由此驱动件3与第一涡旋盘11固定连接。
参见1、图2、图3、图6、图7、图9、图10、图12、图13、图15、图16、图19、图20、图25至图30，在本发明的实施例中， 驱动件3的凸缘部32具有驱动件销孔322。涡旋盘盖6具有涡旋盘盖销孔，销***涡旋盘盖销孔和驱动件3的凸缘部32的驱动件销孔322，以确定涡旋盘盖6与驱动件3的相对位置，由此确定第一涡旋盘11与驱动件3的相对位置。
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，可以部分地阻止在高速下润滑油流出止推面。
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2至图5、图25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。
