    • The scroll compressor 10 includes a housing 12, a fixed scroll 18, an orbital scroll 24, an axial thrust and rotation prevention assembly 46, and an orbital scroll drive. The orbital scroll drive includes a crankshaft 74 rotatably journaled in the housing 12. The crankshaft includes an integral disk 76 and an eccentric crank pin 78 with a lubrication passage 96. An eccentric bushing 80 is journaled on the crank pin 78 and in a boss 82 on the orbital scroll by a needle bearing 81. An eccentric bushing retainer 102 has a shank portion 104 that is pressed into the lubrication passage 96 and an enlarged head portion 106 which holds the eccentric bushing 80 on the crank pin 78. If the eccentric bushing retainer 102 becomes partially unseated from the lubrication passage 96, the surface 114 on the enlarged head portion 106 will contact a surface 116 on the end plate 26 of the orbital scroll 24 and keep the eccentric bushing 80 properly positioned within the compressor housing 12. A passage 120 may be provided in the eccentric bushing retainer 102 to control lubrication of the eccentric bushing 80. The eccentric bushing retainer 102 can be made from plastics and other materials which will act as a bearing surface in the event contact is made with the surface 116 on the orbital scroll 24.
    • 涡旋压缩机10包括壳体12,固定涡旋件18,轨道涡旋盘24,轴向推力和旋转防止组件46以及轨道涡旋驱动器。 轨道涡旋驱动器包括可旋转地轴颈支撑在壳体12中的曲轴74.曲轴包括一体式盘76和具有润滑通道96的偏心曲柄销78.偏心衬套80轴颈支撑在曲柄销78上并在凸台82 通过滚针轴承81在轨道涡卷上。偏心套管保持器102具有被压入润滑通道96的柄部分104和将偏心衬套80保持在曲柄销78上的扩大头部106.如果偏心衬套 保持器102从润滑通道96部分地脱开,扩大头部106上的表面114将接触轨道涡旋盘24的端板26上的表面116,并使偏心衬套80适当地定位在压缩机壳体12内。 通道120可以设置在偏心衬套保持器102中以控制偏心衬套80的润滑。偏心衬套保持器102可以由塑料制成 在与轨道盘24上的表面116接触的情况下,将用作支承表面的其它材料。

    • The present invention relates to a method of forming an enclosure assembly without using tools or fasteners to complete the assembly. The method includes forming a base from a side support, front support, and a plurality of casters. A door assembly and back wall are coupled to the base by aligning a plurality of pegs therefrom with corresponding openings defined in the base. A plurality of protruding wires of a bottom wall are aligned and inserted into corresponding openings defined in the door assembly and back wall. In addition, a plurality of pegs that protrude from a side wall are inserted into a plurality of corresponding openings defined in the door assembly and back wall such that the side wall couples to the door assembly and back wall. The method also includes coupling a top wall to the door assembly, side wall, and back wall. A shelf assembly can be coupled to the side wall and/or back wall, and a ramp can be pivotably coupled to the shelf assembly.
    • 本发明涉及一种在不使用工具或紧固件来完成组件的情况下形成外壳组件的方法。 该方法包括从侧支撑件,前支撑件和多个脚轮形成基座。 门组件和后壁通过与其中的多个钉对准从而与基座中限定的相应开口对齐而联接到基座。 底壁的多根突出的线对齐并插入限定在门组件和后壁中的对应的开口中。 此外,从侧壁突出的多个钉被插入限定在门组件和后壁中的多个对应的开口中,使得侧壁耦合到门组件和后壁。 该方法还包括将顶壁连接到门组件,侧壁和后壁。 搁板组件可以联接到侧壁和/或后壁,并且斜面可以可枢转地联接到搁架组件。
