Abstract
The utility model discloses an improved bearing structure of a dynamic scroll plate of a scroll compressor. The structure comprises a shaft sleeve, a bearing which is arranged in the shaft sleeve, and an eccentric sleeve which is arranged in the bearing, wherein the bearing adopts a ball bearing, and is in interference fit with the eccentric sleeve. According to the improved bearing structure of the dynamic scroll plate of the scroll compressor, the defects in the prior art can be overcome; and by virtue of the ball bearing, the abrasion between the eccentric sleeve and the bearing is avoided, the service life of the scroll compressor is prolonged, and the cost is saved.
Description
Technical field
The utility model relates to the scroll compressor field, and especially a kind of improved scroll compressor moves the scroll bearing structure.
Background technique
Scroll compressor is the circle round compressor of the collapsible volume that the moving scroll of involute formula of translation forms of off-centre by a fixing involute formula fixed scroll and one.Fixed scroll and moving scroll are formed a plurality of pressing chambers.Along with the translation of moving scroll is rotated, each pressing chamber internal volume constantly changes, and realizes suction and compression to gas.The unique design of scroll compressor makes it become world today's energy-saving compressor.Have only dirty to close not wearing and tearing between the moving scroll of scroll compressor and the fixed scroll, thereby the life-span is longer, is described as the freedom from repairs compressor.Scroll compressor operates steadily.Vibrate little, working environment is quiet, is described as super static compression machine again.Scroll compressor novel structure, precision, have that volume is little, noise is low, in light weight, vibration is little, energy consumption is little, the life-span is long, gas transmission advantage such as steady, reliable, source of the gas cleaning continuously.
The moving scroll bearing of common scroll compressor is needle roller, this just proposes very high requirement to degree of finish and the hardness on the eccentric bushing surface that links to each other with main shaft, because the eccentric bushing surface directly contacts with the bearing of moving scroll, main axis rotation institute work becomes the thrust that drives moving scroll after by eccentric bushing, eccentric bushing in the work of reality with the needle bearing of moving scroll not at same rotation center.Off-centre rotation by eccentric bushing cooperates the needle bearing rotation in the moving scroll to make the scroll motion.So the wearing and tearing of eccentric bushing are more serious.And needle bearing also has wearing and tearing.
The model utility content
The technical problems to be solved in the utility model provides the moving scroll bearing structure of a kind of improved scroll compressor, can solve the deficiencies in the prior art, by adopting ball bearing, avoid the wearing and tearing between eccentric bushing and the bearing, prolong service life of equipment, saved cost.
For solving the problems of the technologies described above, technical solution adopted in the utility model is as follows.
A kind of improved scroll compressor moves the scroll bearing structure, comprises axle sleeve in the structure, is installed on the bearing in the axle sleeve and is installed in eccentric bushing in the bearing, and described bearing adopts ball bearing, adopts the interference fit installation between described bearing and the described eccentric bushing.
As a kind of optimal technical scheme of the present utility model, described axle sleeve surface evenly is provided with four through holes.
As a kind of optimal technical scheme of the present utility model, be provided with ten balls in the described bearing, the thickness of described bearing is 15.75 millimeters.
As a kind of optimal technical scheme of the present utility model, described bearing is double row bearing.
The beneficial effect that adopts technique scheme to bring is: the utility model is by adopting ball bearing, adopt interference fit to install between bearing and the described eccentric bushing, avoid the wearing and tearing between eccentric bushing and the bearing, reduced the requirement to hardness and the degree of finish on eccentric bushing surface.Because the characteristic of the ball point of ball bearing contact is compared with needle bearing, because the little resistance to motion of area of contact diminishes, noise reduces, and is energy-conservation.Overall structure reliability height.
Description of drawings
Fig. 1 is the schematic representation of an embodiment of the utility model.
Fig. 2 is that embodiment of the utility model is along the sectional view of A-A direction.
Among the figure: 1, axle sleeve; 2, bearing; 3, eccentric bushing; 4, through hole; 5, ball.
Embodiment
Referring to accompanying drawing 1 and accompanying drawing 2, comprise axle sleeve 1 in the utility model structure, be installed on the bearing 2 in the axle sleeve 1 and be installed in eccentric bushing 3 in the bearing 2 that described bearing 2 adopts ball bearings, adopts the interference fit installation between described bearing 2 and the described eccentric bushing 3.Described axle sleeve 1 surface evenly is provided with four through holes 4.Be provided with ten balls 5 in the described bearing 2, the thickness of described bearing 2 is 15.75 millimeters.Described bearing 2 is double row bearing.
Referring to accompanying drawing, the utility model adopts interference fit to install by adopting ball bearing between described bearing 2 and the described eccentric bushing 3, avoided the wearing and tearing between eccentric bushing 3 and the bearing 2, has reduced the hardness on eccentric bushing 3 surfaces and the requirement of degree of finish.Because the ball 5 of ball bearing is the characteristic of some contact, area of contact is little, so resistance to motion diminishes, noise reduces, and is energy-conservation.Overall structure reliability height.
Foregoing description only proposes as the enforceable technological scheme of the utility model, not as the single restrictive condition to its technological scheme itself.
