Abstract
The invention discloses a sealed type compressor with a rolling piston, which comprises a shell, wherein a motor component and a compressor component are arranged in the shell; the motor component comprises a stator, a rotor, a crank shaft and the like; and the compressor component comprises a cylinder, a piston, an upper bearing, a lower bearing and the like. The piston adopts the rolling pistonwhich can adopt a ball roller bearing or a rolling bearing with similar performances. The sealed type compressor with the rolling piston changes a sliding piston into the rolling piston, so the innerwall of the rolling piston is in interference fit with an eccentric part of the crank shaft during mounting, and the sliding friction between the original piston wall and the eccentric part of the crank shaft is changed into rolling friction. Therefore, the friction loss is greatly reduced, and the efficiency of the compressor is improved.
Description
Technical field
The invention belongs to a kind of compressor, be specifically related to a kind of sliding piston be changed into rolling piston, eliminate sliding friction, improve the hermetic type compressor with rolling piston of compressor efficiency.
Background technique
As shown in Figure 1, 2, the compressor of prior art, the upper inside that is included in housing 1 is equipped with electric machine assembly 20, at the downside of electric machine assembly 20 compressor assembly 30 that is equipped with separated by a distance.Housing 1 is made up of cylindrical drum 11, loam cake 12 and the lower cover 13 etc. of hollow.Electric machine assembly 20 is pressed on the inner peripheral surface that is fixed on cylindrical shell 11, and it is made up of stator 21, rotor 22 and rotary crankshaft 23 of being pressed into the center that is fixed on rotor 22 and transmitting rotating force etc.
In addition, be provided with exhaust port (not shown) in the upper bearing (metal) 32, its upside binding is fixed with baffler 34, is used to reduce the noise that is produced by pressure difference from the compressed media gas of exhaust port discharge.Be provided with suction pipe 50 in the bottom of seal casinghousing 1, be discharged to seal casinghousing 1 outside, on loam cake 12, be provided with discharge tube 51, on loam cake 12, also be provided with the wiring terminal 52 that connects power line for making dielectric gas by baffler 34.
The working principle of compressor and process:
After motor was connected power initiation, bent axle began to rotate, and piston carries out the rotation of rotation and revolution under the drive of crankshaft eccentric portion, because baffle plate is suction area and compressing area with compression volume C zoning, when crankshaft rotating one during week, piston rotates a circle around cylinder, and air-inlet cavity is finished intake process.Meanwhile, compression chamber is finished compression and exhaust process.
But, in the compressor of prior art, piston 35 adopts sliding piston, the eccentric part 23a of piston 35 inwalls and bent axle cooperates for being slidingly matched, has certain clearance between the eccentric part 23a of piston 35 inwalls and bent axle, between the eccentric part 23a of piston 35 inwalls and bent axle is sliding friction, and the energy that sliding friction consumes is big, has reduced the efficient of compressor.
Summary of the invention
The present invention its objective is that for the shortcoming that overcomes prior art proposes providing a kind of changes into rolling piston with sliding piston, eliminates the hermetic type compressor with rolling piston of sliding friction, raising compressor efficiency.
Technological scheme of the present invention is: a kind of hermetic type compressor with rolling piston, comprise housing, housing is made up of cylindrical shell, loam cake and lower cover, electric machine assembly and compressor assembly are installed in housing, electric machine assembly is made up of stator, rotor and bent axle, and compressor assembly is made up of cylinder, upper bearing (metal), piston and lower bearing.
The inner peripheral surface of cylinder and the outer peripheral surface of piston form compression volume C, and plate washer is suction area and compressing area with compression volume C zoning.
Piston adopts the piston that can roll, and rolling piston adopts the ball roller bearing.
Rolling piston adopts roller bearing.
The eccentric part of rolling piston and bent axle is taked interference fit.
The present invention is owing to change into rolling piston with sliding piston, the eccentric part of rolling piston and bent axle is taked the mode of interference fit during installation, in the cylinder of exitting then, like this when compressor operating, the cylindrical of rolling piston remains to roll with cylinder inner wall and contacts, and produces rolling friction.But, the sliding friction between the eccentric part of original sliding piston inwall and bent axle has been become the rolling friction of the eccentric part of rolling piston and bent axle.Reduce frictional loss widely, improved the efficient of compressor.

Embodiment
Below, with reference to drawings and Examples the hermetic type compressor with rolling piston of the present invention is elaborated:
Shown in Fig. 1,3～5, the hermetic type compressor with rolling piston of the present invention comprises housing 1, in the upper inside of housing 1 electric machine assembly 20 is installed, at the downside of electric machine assembly 20 compressor assembly 30 that is equipped with separated by a distance.Housing 1 is made up of cylindrical drum 11, loam cake 12 and the lower cover 13 etc. of hollow.Electric machine assembly 20 is pressed on the inner peripheral surface that is fixed on cylindrical shell 11, and it is made up of stator 21, rotor 22 and rotary crankshaft 23 of being pressed into the center that is fixed on rotor 22 and transmitting rotating force etc.
In addition, be provided with exhaust port (not shown) in the upper bearing (metal) 32, its upside binding is fixed with baffler 34, is used to reduce the noise that is produced by pressure difference from the compressed media gas of exhaust port discharge.Be provided with suction pipe 50 in the bottom of seal casinghousing 1, be discharged to seal casinghousing 1 outside, on loam cake 12, be provided with discharge tube 51, on loam cake 12, also be provided with the wiring terminal 52 that connects power line for making dielectric gas by baffler 34.
Wherein rolling piston 37 adopts the ball rolling bearing, also can adopt the rolling bearing of roller bearing or similar performance.The eccentric part 23a of rolling piston 37 and bent axle takes the mode of interference fit.
The present invention is owing to change into rolling piston with sliding piston, the eccentric part of rolling piston and bent axle is taked the mode of interference fit during installation, puts into cylinder then, like this when compressor operating, the cylindrical of rolling piston remains to roll with cylinder inner wall and contacts, and produces rolling friction.
But the present invention has become the sliding friction between the eccentric part of original sliding piston inwall and bent axle the rolling friction of the eccentric part of rolling piston and bent axle.Reduce frictional loss widely, improved the efficient of compressor.
