Abstract
A refrigerant compressor is provided ,which comprises a clutch of the current refrigerant compressor, a camshaft seat, a cylinder body, a camshaft, and a slide block; what is improved is that the cam is of the oblong shape, and on the two ends of the long shaft of the oblong cam are provided with an automatic adjusting block; and the cylinder body is provided oppositely with two slide blocks, wherein the two sides of each slide block are provided with a high-pressure gas outlet and a gas inlet; and the camshaft is provided with a key way at two opposite sides, while two key ways are provided with a through hole in between, wherein the through hole between the two keys are provided with a pressure spring inside. The utility model has the positive effects of that: compared with the current refrigerant compressor shown in picture 1, under the same air output, the volume of the utility model can be reduced by 20 percents to 40 percents; while under the same volume, the air output of the utility model can be increased to 1.4 or times or so; in addition, the rotation centrifugal force is absolutely balanced and the whole machine is of less vibration; further, the external hull of the utility model has large one-time heat dissipation area, quite favorable to heat dissipation.
Description
Technical field
The utility model belongs to refrigeration technology field, is specifically related to a kind of refrigeration compressor.
Background technique
At present the refrigeration compressor kind is more, and by compression mode branch, common have piston type, a rotary type, centrifugal.More than different structural type is arranged in each class again, grind formula, eddy type, rotary vane type as the pendulum in the rotary type.To above-mentioned various refrigeration compressors, generally believe that pendulum stone roller formula is more advanced.In the basic structure of pendulum stone roller formula refrigeration compressor, comprise the common belt pulley of all kinds of refrigeration compressors, clutch, shell, cylinder body, compression element live axle, axle sit, the structure of its refrigeration agent compression member is as shown in Figure 1: wherein sequence number 1 is a cylinder body, 2 is inner chamber, 3 is slide block, 4 is rolling ring, and 5 are just round eccentric cam, and 6 is the cam drive axle.The groundwork process is that cam 5 rotates, and cam 5 relative rolling rings 4 slide, and rolling ring 4 rolls at inboard wall of cylinder block, and cam mechanism matches with slide block 3, intake valve 6, exhaust valve 7, realizes refrigerant compression work.The advantage of this kind refrigeration compressor has: volume is little, in light weight, and the automatic adjusting play of rolling ring and cylinder body has air-flow path preferably, low noise, and fuel-economizing does not have specific (special) requirements to the refrigeration system miscellaneous part, and matching performance is strong.Though pendulum stone roller formula refrigeration compressor has above-mentioned advantage than existing other types refrigeration compressor, and its deficiency is also arranged.What should overcome has: cam rotates a circle, and once (i.e. compression once) working efficiency is not high for suction, exhaust.Be eccentric cam mechanism, the radial force of camshaft is just uneven, and consequent vibrations are unavoidable.
Summary of the invention
The purpose of this invention is to provide a kind of refrigeration compressor, overcome the above-mentioned shortcoming that existing refrigeration compressor exists.
The utility model comprises the clutch of existing refrigeration compressor, camshaft holder, cylinder body, camshaft, slide block, the improvement of being done is: employed cam is for oval, and the axis hole of elliptic cam is in elliptical center, on the cylinder at the protruding major axis two ends of elliptic wheel, axial notch is arranged, place in the groove and adjust piece automatically.On cylinder body, be symmetrical arranged two slide blocks.In the side in face of the elliptic cam sense of rotation of each slide block, establish the pressurized gas outlet.Establish the gas suction port at the opposite side of slide block.More than be basic scheme of the present utility model.
To eliminate inner chamber of cylinder block, elliptic cam, camshaft machining error and assembly error cam and the pressure between cylinder body in causing rotating unbalanced in order to make, and symmetry both sides in the position of stationary cam spline on camshaft, between two keyways through hole are arranged.Cam is installed in when spool last, key and keyway movingly, dress pressure spring in the through hole between two keys.
In order to reduce the pressure of slide block side to the slide block cylinder body, keep its flexible flexibility, slide block is to tilting to install in face of the cam sense of rotation.
Good effect of the present utility model is:
1, do twice two-chamber compression, exhaust time action because compressor cam of the present utility model rotates a circle, compare with existing refrigeration compressor shown in Figure 1, under the equal air displacement situation, volume can reduce 20-40%.Under the situation with isometric(al), air displacement can increase about 1.4 times.
2, rotary centrifugal force complete equilibrium, the complete machine vibrations are little.
3, in addition parts are few, few easy workout part particularly, and operational reliability is good.
4, heat diffusion area of shell is big, favourable heat radiation.
6, using scope is wide, can be used for domestic air conditioning, refrigerator, reaches various car air conditioners.
Description of drawings
Fig. 1 is that existing pendulum grinds formula refrigerating compressor structure figure.
Fig. 2 is the utility model master pseudosection.
Fig. 3 is the utility model A-A position pseudosection.
Fig. 4 is the utility model B-B position profile figure.
Embodiment
Provide an embodiment of the present utility model below in conjunction with accompanying drawing.
Adopt the clutch assembly 7 of existing structure, belt pulley 8, shell 9, and with the essentially identical cylinder body 10 of prior art, camshaft 11, camshaft holder 12, with two cylindroids as cam 13, the ratio of cam major and minor axis is about 6: 5, and thickness is equivalent to 1/2 of major axis.Symmetry is driven two keyways on the axis hole of cam center, opens on the cylinder at major axis two ends and adjusts the piece groove.Cams mounted position symmetry is driven two keyways on camshaft 11, drilling radial hole between two keyways, and symmetry is opened slide block slot on cylinder body 10, and slide block slot is in face of camming movement direction inclination 3-5 degree.Slide block slot is established relief opening 14 with prior art in face of a side of camming movement direction.The opposite side of slide block slot is established suction port 15.Dress pressure spring 16 in the radial hole of camshaft, load key 17 in the keyway of both ends of the spring is installed cam again on camshaft, and the keyway of key 17 and cam and camshaft is movingly.On camshaft, load onto simultaneously cylinder body shim 18 and bearing 19.On cylinder body 10, load onto slide block 20.Pack at the groove at cam two ends and to adjust piece 21.The assembling mode of pressing prior art is with camshaft, cylinder body, shell, and camshaft is sat and clutch pack is dressed up integral body, promptly finishes enforcement of the present utility model.
