Problems solved by technology
[0003] The connection of each part of the crankshaft of the existing refrigeration compressor is mostly fixed, and the installation is relatively cumbersome; the connection between the crankshaft of the existing refrigeration compressor and the external connecting rod is mostly realized by the disassembly of the external connecting rod to replace the connecting rod, resulting in the failure of the connecting rod. 1. The strength of the main load-bearing parts becomes lower, which affects its service life; and the existing connecting rods are mostly connected with the crank pin on the crankshaft of the refrigeration compressor. Increased crankshaft rotation energy consumption

The invention discloses a nested assembly type refrigeration compressor crankshaft and an assembly method thereof.The nested assembly type refrigeration compressor crankshaft comprises two correspondingly arranged crank arms, an auxiliary journal and a main journal, the main journal is arranged on one side of one crank arm, the auxiliary journal is arranged on one side of the other crank arm, and a connecting mechanism is arranged between the two crank arms; the connecting mechanism comprises a first crank tip connected to the crank arm, a second crank tip is clamped to one side of the first crank tip, a stabilizing mechanism is arranged on the second crank tip, a second connecting plate is arranged on one side of the auxiliary shaft neck, a rotating mechanism is arranged between the second connecting plate and the auxiliary shaft neck, and a first connecting plate is arranged on one side of the main shaft neck. A rotating part is embedded in the first connecting plate, and an assembling mechanism is arranged between the rotating part and the main journal. By arranging a series of structures, welding is not used for connection needed in the whole process, operation is easy and convenient, the strength of the external connecting rod is improved, the service life of the external connecting rod is prolonged, and the deviation angle of the external connecting rod is reduced.
Description
technical field [0001] The invention relates to the technical field of refrigeration compressor crankshafts, in particular to a nested assembled refrigeration compressor crankshaft and an assembly method thereof. Background technique [0002] The refrigeration compressor is the core and heart of the refrigeration system. The capabilities and characteristics of the compressor determine the capabilities and characteristics of the refrigeration system. In a sense, the design and matching of the refrigeration system is to reflect the capabilities of the compressor and improve the efficiency of the refrigeration system. The most direct and effective means is to improve the efficiency of the compressor, which will bring about a significant reduction in the energy consumption of the system, and the crankshaft of the refrigeration compressor is the main component that converts the rotational force into the piston force. [0003] The connection of various parts of the crankshaft of t...
