双缸旋转式密闭型压缩机的制造方法
摘要：
本发明提供一种双缸旋转式密闭型压缩机的制造方法，向上气缸的内部插入上侧滚动活塞、上侧叶片，将曲轴的上侧偏心部安装于上侧滚动活塞的内径部，使上述曲轴通过中间隔板的内径部，将下侧滚动活塞安装于曲轴的下侧偏心部，组合插入有下侧叶片的下气缸和下轴承的组装品，将曲轴的内径部插入下轴承的内径部中，将下轴承、下气缸、中间隔板连接于上气缸，将上排出罩安装在上轴承的外周部，将上排出罩、上轴承、上气缸、中间隔板连接在下气缸上，暂时将连接了下气缸和下轴承的下轴承连接螺栓拆下，将下排出罩安装在下轴承的外周部，连接下排出罩、下轴承和下气缸，在作为曲轴的旋转方向的圆周方向上至少交替地设置各两根上侧贯通螺栓和下侧贯通螺栓。
摘要（英）：

The invention provides a dual-cylinder rotating close-type compressor comprising an electromotion element being held at the upper part of a close housing; a compression mechanism section being held at the lower part of the close housing and comprising an upper bearing, an upper cylinder, a central clapboard, a lower cylinder and a lower bearing, and being driven by the electromotion element via acrankshaft; the upper transfixion bolts for fixing the upper bearing, the upper cylinder, the central clapboard to the lower cylinder from the upper bearing side; and lower transfixion bolts for fixing the lower bearing, the lower cylinder, the central clapboard to the upper cylinder from the lower bearing side, and in addition, at least two lower transfixion bolts and two lower transfixion boltsare alternately arranged along the circumferential direction of the crank shaft rotation direction.
