Abstract

The invention discloses a reciprocating compressor, relates to the technical field of compressors, and aims to solve the problem that the energy consumption of the compressor is increased due to the fact that the distance between two kinematic pairs formed by matching a crankshaft of the existing reciprocating compressor with a crankshaft hole of a cylinder seat is small and the shaft pressure is increased. The invention relates to the reciprocating compressor which comprises an air cylinder seat, a bottom plate and a crankshaft, and the air cylinder seat is provided with a crankshaft matching hole; the bottom plate is provided with an aligning device, a mounting hole is formed in the aligning device, and the bottom plate is fixedly connected with the air cylinder seat and located below the air cylinder seat; and a first matching shaft section is arranged on the side, close to a short shaft of the crankshaft, of a long shaft of the crankshaft, a second matching shaft section is arranged on the side, away from the short shaft of the crankshaft, of the long shaft of the crankshaft, and the long shaft sequentially penetrates through the crankshaft matching hole and the mounting hole. By increasing the distance between the matching sections of the crankshaft, the problem that the shaft pressure of the crankshaft mounting hole of the reciprocating compressor is large is solved, and the efficiency of the compressor is improved.

Description

technical field [0001] The invention relates to the technical field of compressors, in particular to a reciprocating compressor. Background technique [0002] With the development of the economy and the improvement of people's living standards, the market's pursuit of user experience and quality of refrigerators has also gradually improved. In recent years, large-volume refrigerators have developed rapidly, but energy conservation and environmental protection have always been the goal pursued by the home appliance industry. Ordinary inverter compressors can no longer meet the matching needs of the high-end refrigerator market. [0003] The existing reciprocating compressor structure has certain limitations in improving energy efficiency, especially the design of the crankshaft, which is the core component of the compressor. Usually, the two mating shaft sections of the crankshaft are assembled with the crankshaft hole of the cylinder block to form a kinematic pair. In order...
