具体实施方式
下面通过实施例，并结合附图，对本发明的技术方案作进一步具体的说明。在说明书中，相同或相似的附图标记指示相同或相似的部件。下述参照附图对本发明实施方式的说明旨在对本发明的总体发明构思进行解释，而不应当理解为对本发明的一种限制。
另外，在下面的详细描述中，为便于解释，阐述了许多具体的细节以提供对本披露实施例的全面理解。然而明显地，一个或多个实施例在没有这些具体细节的情况下也可以被实施。在其他情况下，公知的结构和装置以图示的方式体现以简化附图。
涡旋压缩机中，涡旋本身的质心和几何中心很难靠近或重合，导致在涡旋压缩机在转动时的不稳定，限制了涡旋转速的提高和压缩机效率的提高。
参见图1，本申请公开了一种压缩机1000，包括：第一涡旋件10、第二涡旋件20、支架50、电机40、以及驱动件60。
第一涡旋件10和第二涡旋件20相互配合以形成压缩腔，压缩腔接收被进送到压缩机1000中的流体。第一涡旋件10包括第一端板11和从第一端板11朝向第二涡旋件20延伸出的第一涡卷12，第二涡旋件20包括第二端板21和从第二端板21朝向第一涡旋件10延伸出的第二涡卷22。支架50位于第二涡旋件20的远离第一涡旋件10 的一侧，驱动件60被可转动地支撑于支架50并且位于第二端板21的远离第一端板11的一侧。驱动件60包括凸缘61和从凸缘61朝背离第一涡旋件10和第二涡旋件20的方向延伸的毂部62。毂部62包括相对的第一端部和第二端部并且可转动地安装于支架50。凸缘101从第一端部径向向外伸出。驱动件60设置有延伸穿过毂部62和凸缘61的内孔。第一涡卷12的一部分被支撑和连接到凸缘61上，第二端板21也被可转动地支撑在凸缘61上。电机40可选地是轴向磁通电机，这有利于减小压缩机1000的体积。电机40包括转子41和定子42。定子42被固定地支撑在支架50上，转子41被可转动地支撑于定子42并与毂部62过盈配合，使得电机40能够通过驱动驱动件60转动，以驱动第一涡旋件10旋转，第一涡旋件10又驱动第二涡旋件20旋转，以压缩进入压缩腔中的流体。
第一涡旋件10和第二涡旋件20一起旋转有利于第一涡旋件10和第二涡旋件20二者在转动过程中彼此平衡对方所生成的离心力，从而避免了设置平衡块来平衡涡旋件10、20转动所生成的离心力，简化了压缩机1000的结构并减小了压缩机1000的体积。
参见图2至4，第一涡卷12的根部连接到第一端板11上，第一涡卷12的端部抵靠在第二端板21上，并且第二涡卷22的根部连接到第二端板21上，第二涡卷22的端部抵靠在第一端板11上。压缩机1000还包括：用于提高压缩腔的密封性的第一密封件121和第二密封件221，在第一涡卷12的端部中设置有用于安装第一密封件121的第一槽，在第二涡卷22的端部中设置有用于安装第二密封件221的第二槽。
在图3示出的实施例中，第一涡卷12和第二涡卷22的壁的厚度沿从各自的根部朝各自的端部的方向是大致恒定的。在图4示出的实施例中，第一涡卷12和第二涡卷22的壁的厚度沿从各自的根部朝各自的端部的方向逐渐变薄。
图5是示出图2中的组装到一起的第一涡旋件和第二涡旋件的侧视图。图6是沿图5中的线6-6截取的仰视截面图。参见图6，在第一端板11中设置有靠近第一端板11的几何中心并用于排出压缩腔中 的流体的排放口111以及使流体进入压缩腔中的进入口112，第一涡卷12的中心靠近排放口，第一涡卷12的末端靠近进入口112。从进入口112进入压缩腔中的流体随着第一涡卷12和第二涡卷22相对转动而被压缩，同时在压缩腔中朝排放口111移动并在压缩结束后从排放口111排出。
下面将参照图7和8详细描述第一涡卷12和第二涡卷22的形状。第一涡卷12被构造为第一型线的形状以使第一涡旋件10的质心与第一涡旋件10的旋转中心接近重合或重合；和/或，第二涡卷22被构造为第二型线的形状以使第二涡旋件20的质心与第二涡旋件20的旋转中心接近重合或重合，如下文进一步详细描述的，第一型线和第二型线分别由复合型线限定，复合型线由渐开线和圆弧的组合限定。涡旋件10、20的质心与各自的旋转中心重合有利于涡旋件10、20的稳定转动以及提高压缩机1000的压缩比，也有利于减小涡旋件10、20和压缩机1000的体积。
