Abstract
The utility model discloses a rotary compressor, which comprises a shell body, a stator, a rotor, a crank shaft and a pump, wherein the stator, the rotor, the crank shaft and the pump are arranged in the shell body. The stator is sheathed at the outer part of the rotor, and the rotor is connected with the crank shaft. The pump is arranged in the shell body through a bearing, and the crank shaft penetrates through the bearing. The bearing comprises an upper bearing and a lower bearing, and the pump is arranged between the upper bearing and the lower bearing. The upper bearing and the lower bearing are made of powder metallurgy material. An exhaust valve is arranged on the upper bearing. The pump comprises a cylinder body and a ring, and the ring is connected with the crank shaft and performs eccentric motion in the cylinder body. The rotary compressor has the advantages of simple structure and high operational stability.
Description
Technical field
The utility model relates to a kind of refrigeration compressor, is specifically related to a kind of high working efficiency, stable idle call rotary compressor.
Background technique
Rotary compressor comprises motor, pumping, shell, filter bottle, foot rest, top cover, bottom, and wherein, pumping comprises cylinder body, ring, bent axle, metal (upper, silencer cover.Usually, pumping is welded on stationary positioned on the shell through bearing, and compressor case often adopts carbon steel material, and bearing often adopts cast iron materials.This kind cast iron bearing has following shortcoming: when adopting the machining mode to produce complex-shaped bearing, manufacturing efficiency is low, cost is high; Be easy to generate defectives such as pore, pin hole, slag inclusion, crackle, pit during welding, influence the visual quality of casting and internal soundness, when serious foundry goods is scrapped, dimensional uniformity is poor, finally can influence the compressor product quality stability.Because carbon steel material and cast iron materials property difference are bigger, when welding, need bigger welding current and long weld interval, so tangible thermal distortion takes place when causing welding, the performance of compressor is exerted an adverse impact.
The model utility content
The purpose of the utility model is to provide a kind of rotary compressor, and this compressor operating efficient is high, stable.
The utility model to achieve these goals, the technical solution of employing is:
Rotary compressor comprises housing and the stator, rotor, bent axle and the pumping that are arranged in the housing, and stator is enclosed within rotor exterior, and rotor connects bent axle, and pumping is arranged in the housing through bearing, and bent axle passes bearing.
Further, said bearing is processed by powdered metallurgical material.
Further, said bearing comprises upper bearing (metal) and lower bearing, and pumping is arranged between upper bearing (metal) and the lower bearing.
Further, said upper bearing (metal) is provided with outlet valve.
Further, said pumping comprises cylinder body and ring, the ring be connected with bent axle, and in cylinder body eccentric motion.
The beneficial effect of the utility model:
This kind rotary compressor is simple in structure, and operation stability is high.Bearing adopts powdered metallurgical material to process, and powdered metallurgical material can bear load such as stretching, compression, distortion, and can under friction, abrasive conditions, work.Powdered metallurgical material have traditional founding the unique chemical composition that can't obtain and physics, mechanical property, the porosity of material is controlled, material structure evenly, no gross segregation, can realize once-through.Bearing can reduce the machining operation by mould-forming, improves work efficiency, guarantees the conformity of size, improves compressor constant product quality property, and reduces cost.
Description of drawings
Fig. 1 is the structural representation of rotary compressor.
Fig. 2 is the structural representation of upper bearing (metal).
Embodiment
Below in conjunction with accompanying drawing the utility model is elaborated:
In conjunction with Fig. 1, Fig. 2, rotary compressor comprises housing and the stator 1, rotor 2, bent axle 3 and the pumping 4 that are arranged in the housing, and stator 1 is enclosed within rotor 2 outsides, and rotor 2 connects bent axle 3, and pumping 4 is arranged in the housing through bearing, and bent axle 3 passes bearing.Bearing comprises upper bearing (metal) 5 and lower bearing 6, and pumping 4 is arranged between upper bearing (metal) 5 and the lower bearing 6, and upper bearing (metal) 5 and lower bearing 6 are processed by powdered metallurgical material; Upper bearing (metal) 5 is provided with outlet valve 7; Pumping 4 comprises cylinder body 41 and ring 42, and ring 42 is connected with bent axle 3, and in cylinder body 41 eccentric motion.
This kind rotary compressor is simple in structure, and operation stability is high.Bearing adopts powdered metallurgical material to process, and powdered metallurgical material can bear load such as stretching, compression, distortion, and can under friction, abrasive conditions, work.Powdered metallurgical material have traditional founding the unique chemical composition that can't obtain and physics, mechanical property, the porosity of material is controlled, material structure evenly, no gross segregation, can realize once-through.Bearing can reduce the machining operation by mould-forming, improves work efficiency, guarantees the conformity of size, improves compressor constant product quality property, and reduces cost.
Certainly; Above-mentioned explanation is not to be the restriction to the utility model; The utility model also be not limited in above-mentioned for example, variation, remodeling, interpolation or replacement that the technician in present technique field is made in the essential scope of the utility model also should belong to the protection domain of the utility model.
