Problems solved by technology
Regardless of the combination, although the ball can be installed in it, the final result is that either the installation accuracy cannot meet the requirements of the compressor; or the service life of the piston is very short.
At the same time, the manufacturing cost and installation difficulty are high, which affects the service life and manufacturing cost of the whole machine

The invention discloses a combined type piston and connecting rod assembly of a refrigeration compressor and an installation method of the assembly. The assembly comprises a rotating connecting rod installation device, a connecting rod and a piston device, and the rotating connecting rod installation device is connected with the piston device through the connecting rod; a rotating connecting rod locating ring is installed in the rotating connecting rod installation device, a rotating connecting rod outer ring, the rotating connecting rod locating ring and a crank rotating connecting rod stationary shaft are concentrically installed, the crank rotating connecting rod stationary shaft is fixedly connected with the connecting rod, and the connecting rod is connected with the piston device; a piston skirt, a spherical support and a spherical upper cover are installed in the piston device, and the assembly can always move concentrically and coaxially on the condition of ensuring the high lubrication degree through formed oil grooves, a formed oil hole and a formed oil chamber. Accordingly, the installation method is simple and practical, the installation precision is high, the structure is simple, the assembly manufacturing difficulty is low, firmness and durability are achieved, the working efficiency is improved, and the service life is prolonged.
Description
technical field [0001] The invention relates to the field of refrigeration equipment, in particular to a refrigeration compressor combined piston and connecting rod assembly and an installation method thereof. Background technique [0002] Whether it is a refrigerator or a freezer and other refrigeration equipment, their "heart" is a fully enclosed piston compressor. It is the piston in the "heart" that drives the flow of refrigerant. The piston is driven by the crankshaft, and through the transmission of the force of the connecting rod, the piston is driven to perform telescopic and reciprocating linear motion in the cylinder. Because the connecting rod is in the compound motion of swinging back and forth and left and right when it works, and the piston is in linear motion. In order to eliminate the interference on the piston caused by the external force in the direction of non-linear motion caused by the swing of the connecting rod, the existing connection between the pi...
