Abstract

The invention provides a pump body assembly, a compressor and an air conditioner. The pump body assembly comprises a crankshaft (1), the crankshaft (1) comprises a first eccentric part (12) and a second eccentric part (15) which are axially arranged at intervals, wherein a first partition plate (6) and a second partition plate (7) are sequentially arranged between the first eccentric part (12) andthe second eccentric part (15), a first round hole (17) is formed in the first partition plate (6), a supporting shaft (13) is arranged in the first round hole (17), and the first partition plate (6)and the supporting shaft (13) form a partition plate bearing; and the partition plate bearing is provided with a stress reduction structure for reducing the contact stress between the support shaft (13) and the first partition plate (6). According to the pump body assembly, the problem of bearing abrasion caused by overlarge local stress can be solved, and the service life of the partition platebearing is 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 customers' continuous improvement of cooling capacity and heating capacity of air conditioners, the displacement of rotary compressors is also increasing. Due to the size limit of the external unit of the air conditioner, the diameter of the compressor shell should be as small as possible. It is necessary to make the height of the cylinder of the pump body higher, especially when the two ends of the large-displacement cylinder need to be provided with exhaust ports. The greater the span of the eccentric portion of the crankshaft between the cylinders. [0003] The two eccentric parts of conventional rotor compressors are in a suspended state. During the working process, due to the excessive deflection between the two eccentric parts, the eccentric part and...
