Abstract

The application provides a pump body assembly, a compressor and an air conditioner. The pump body assembly includes a crankshaft (1), and the crankshaft (1) includes a first eccentric portion (12) and a second eccentric portion (15) arranged axially at intervals, and the first eccentric portion (12) and the second eccentric portion (15) ) between the first partition (6) and the second partition (7), the first partition (6) is provided with the first round hole (17), the first round hole (17) is provided with The support shaft (13), the first dividing plate (6) and the supporting shaft (13) form a dividing plate bearing, and the dividing plate bearing is provided with reducing contact stress between the supporting shaft (13) and the first dividing plate (6). stress relief structure. According to the pump body assembly of the present application, the problem of bearing wear caused by excessive local stress can be reduced, and the service life of the separator bearing can be prolonged.

Description

technical field [0001] The present application relates to the technical field of air conditioning, in particular to a pump body assembly, a compressor and an air conditioner. Background technique [0002] In order to meet the continuous improvement of the cooling capacity and heating capacity of air conditioners by customers, the displacement of the rotary rotor compressor is also increasing. It is necessary to make the height of the pump body cylinder higher, especially when the two ends of the large displacement cylinder need to be provided with exhaust ports, and the exhaust ports are arranged on the partition, the partition plate needs to be designed higher, so the two sides of the pump body need to be set higher. The greater the span of the crankshaft eccentric portion between the cylinders is. [0003] The two eccentric parts of the conventional rotary compressor are in a suspended state. During the working process, due to the excessive deflection between the two ecce...
