Assembling method of compressor with piston driven by gear mechanism

The invention discloses an assembling method of a compressor with a piston driven by a gear mechanism. A main transmission gear (4) fixedly connected with a motor main shaft (10) is arranged at the end of the motor main shaft (10), and the main transmission gear (4) is a cylindrical outer gear; the main transmission gear (4) meshes with an inner gear; the inner gear is connected with the piston (6) through a connecting rod (11); and the connecting rod (11) and the inner gear are fixedly connected into a whole. With adoption of the technical scheme, vibration and noise of the compressor are reduced; the oil discharge amount of lubricating oil is small, and meanwhile, the refrigeration efficiency is improved. 本发明公开了一种齿轮机构驱动活塞的压缩机的装配方法，所述的电机主轴(10)端部设置与电机主轴(10)固定连接的主传动齿轮(4)，所述的主传动齿轮(4)为圆柱外齿轮；所述的主传动齿轮(4)与内齿轮啮合；所述的内齿轮通过连杆(11)与活塞(6)连接；所述的连杆(11)与内齿轮固定连接为一个整体。采用上述技术方案，降低压缩机的振动和噪音；其润滑油的排油少，同时，提高了制冷效率。
