Background technique
In general, compressor is the part in the freezing cycle device, is to pressurizes refrigerant, makes the pressure of refrigeration agent and the device that temperature is fit to special purpose.Freezing cycle device comprises that compressor, condenser, expansion gear, vaporizer constitute, and each parts interconnects, and constitutes the circulatory system of sealing.
This freezing cycle device, compression is drawn into the refrigerant gas of the low-temp low-pressure state in the compressor, discharge with high-temperature high-pressure state, and the refrigerant gas of discharging discharges latent heat to the outside by condenser the time, thus the liquid state of being converted into.Simultaneously, by expansion gear the time, reduce pressure, and then, evaporate the refrigeration agent of low-pressure state, thereby absorb outside heat by in the process of vaporizer.And vaporized refrigeration agent then flow in the compressor again, thus said process repeatedly.
Freezing cycle device generally is installed on the electrical equipment such as air conditioner or refrigerator, thereby utilizes cold air and the hot gas that forms in condenser and vaporizer, and comfort level in the holding chamber or assurance food are fresh.
Fig. 1 is a rotary compressor structure sectional view.Rotary compressor as shown in Figure 1, its main structure includes casing 10, mechanism portion and compression mechanical part.The bottom of casing is provided with oil groove 14 and stores a certain amount of lubricant oil, and connection is provided with gas suction pipe 7; Mechanism portion is arranged on the top of casing and produces rotating force; Compression mechanical part is arranged on the bottom of casing and utilizes the rotating force compressed refrigerant.
Mechanism portion is to be made of stator 2 and rotor 3.Stator is fixed on the inside of casing and from outside turn-on power, rotor rotates every fixed gap installation and with stator is interactional simultaneously in the inside of stator.
The main structure of compression mechanical part includes cylinder 12, upper bearing (metal) 6 and lower bearing 8, running shaft 5, rolling piston 13.Wherein, cylinder forms annular and is arranged on the inside of casing; Upper bearing (metal) and lower bearing cover the upper and lower surface of cylinder separately and form the inner space together; Running shaft is pressed in the rotor, and is supported and the transmission rotating force by upper bearing (metal) and lower bearing; Rolling piston is contained in the rotating shaft eccentric portion 11 rotation, and when circling round in the inner space of cylinder compressed refrigerant.
Cylinder one end is connected with gas suction pipe; Be provided with main oil-hole 15 in rotating shaft center, running shaft also is shaped on the lower bearing oilhole 17 of the upper bearing (metal) oilhole 16 of the lubricated upper bearing (metal) that is communicated with main oil-hole, lubricated lower bearing, the rolling piston oilhole 18 of lubricated rolling piston at different parts; The rolling piston oilhole is located on the running shaft relative with rotating shaft eccentric portion.
Rolling piston oilhole on the present rotary compressor running shaft is located on the running shaft relative with rotating shaft eccentric portion, there is following problem in the running shaft of this structure: when compressor operating, because the existence of rotating shaft eccentric portion, producing centrifugal force during its work is the main vibratory source that compressor radially shakes.And the present position at rolling piston oilhole place has reduced the quality of this part running shaft relative with rotating shaft eccentric portion, has strengthened the quality of eccentric part, and then has strengthened the epitrochanterian mass of balance block of mechanism portion.
Summary of the invention
The utility model provides a kind of rolling piston oilhole of lubricated rolling piston to be located in the rotating shaft eccentric portion for solving the technical problem that exists in the known technology, can reduce the revolute axes configuration of the rotary compressor of eccentric part quality.
The technological scheme that the utility model is taked for the technical problem that exists in the solution known technology is:
The revolute axes configuration of the utility model rotary compressor, the structure of rotary compressor comprises: by the loam cake of housing, the sealed at both ends connection of housing and the casing that drain pan is formed; The mechanism portion that the rotor that is fixed on the stator on the casing and rotates in stator is formed; Running shaft in the rotor center combination, the upper bearing (metal) of the supporting rotating shaft the other end, lower bearing, form annular and be fixed on the cylinder of casing inside, the upper and lower surface that upper bearing (metal), lower bearing cover cylinder forms the inner space together, in cylinder interior, be contained in the compression mechanical part of the annular rolling piston composition that rotates in the rotating shaft eccentric portion; Cylinder one end is connected with gas suction pipe; The bottom of casing is provided with oil groove.
Be provided with main oil-hole in rotating shaft center, running shaft also is shaped on the upper bearing (metal) oilhole of the lubricated upper bearing (metal) that is communicated with main oil-hole at different parts, the lower bearing oilhole of lubricated lower bearing, the rolling piston oilhole of lubricated rolling piston; Its rolling piston oilhole is located in the rotating shaft eccentric portion.
The utility model can also adopt following technical measures:
The quantity of described rolling piston oilhole is at least 1.
Advantage and the good effect that the utlity model has are:
The revolute axes configuration of the utility model rotary compressor because the rolling piston oilhole is located in the rotating shaft eccentric portion, has reduced the eccentric part quality, and the centrifugal force that produces during running shaft work reduces, and has reduced the vibrations of compressor.Reduce the epitrochanterian mass of balance block of mechanism portion simultaneously, saved cost.And improved lubrication effect.
