旋转式压缩机制造技术

本发明专利技术提供了一种旋转式压缩机，所要解决的问题是：采用增大轴承外径解决缸体在焊接时产生变形的问题，其本身仍会产生一定的变形；在压缩部件与壳体之间采用机架连接，装配工艺复杂，成本较高。本发明专利技术的要点是：轴承为组合式轴承，它由圆柱法兰型轴承主体和环壁呈L形的环状连接架组成，该连接架形成上大口径、下小口径，轴承主体从连接架的上面将其法兰盘固定在连接架的小口径上。压缩部件通过组合轴承上的连接架与密闭壳体部件进行连接固定定位。本发明专利技术的有益效果是：焊接时变形发生在连接架上，通过对连接架结构的合理设计和材料的合理选用可使其吸收这部分变形，不再传递到轴承。降低了制造成本，降低了噪声，提高了压缩机质量稳定性。

Rotary compressor

The invention provides a rotary compressor, which is to solve the problem by increasing the diameter of the bearing to solve the deformation problem in the welding cylinder, it still has certain deformation; using frame connection between the compression component and the casing assembly, complex process, high cost. The invention is characterized in that: the bearing is a combined bearing, which is composed of a body flange type bearing ring and cylinder wall of a circular L shaped connecting frame, the connecting frame is formed on the large diameter and small diameter, the main bearing from above the flange connecting frame is fixed on the connecting frame of small caliber. The compression parts are fixedly connected with the closed shell parts by combining a connecting frame on the bearing. The invention has the beneficial effects that when the welding deformation occurs on the connecting frame, the structure of the connecting frame is rationally designed and the material is reasonably selected, so that the part can be absorbed and no longer passed to the bearing. The manufacturing cost is reduced, the noise is reduced, and the quality stability of the compressor is improved.
