Abstract
The utility model discloses a scroll compressor. A bearing seat retainer is fixed on the installing surface of the bearing seat retainer. The steel ball washer of the bearing seat is arranged inside the installing surface of the retainer. A orbiting scroll retainer is fixed on the installing surface of the orbiting scroll retainer. The steel ball washer of the orbiting scroll is arranged outside the installing surface of the retainer. Steel balls are arranged between the two retainers. The distance between the installing surface of the bearing seat retainer and the bearing surface of the steel ball washer of the bearing seat is more than the critical distance therebetween, which interferes in the motion of the steel balls. Or the distance between the installing surface of the orbiting scroll retainer and the bearing surface of the steel ball washer of the orbiting scroll is more than the critical distance therebetween, which interferes in the motion of the steel balls. During the first running of the compressor, raceways are rolled by steel balls on the bearing seat or the orbiting scroll, thereby reducing the loads of the steel balls and their corresponding retainers during the operation of the compressor. The service life of anti-rotation component of thrust ball bearing is also increased, thereby greatly increasing the service life of the above scroll compressor.
Description
Technical field
The utility model relates to a kind of scroll compressor, particularly is applied to the scroll compressor on the traffic tool or the mobile engineering machinery.
Background technique
The reliability of scroll compressor depends primarily on its anti-rotation mechanism that adopts.The existing scroll compressor that is applied on the traffic tool or the portable engineering machinery, as vortex type automobile air conditioner compressor, its anti-rotation mechanism that adopts mainly is the thrust ball bearing anti-rotation mechanism, and this thrust ball bearing anti-rotation mechanism is by being installed in the Moving plate retainer with some through holes, Moving plate steel ball packing ring on the moving scroll, being installed in the bearing support retainer with some through holes, the bearing support steel ball packing ring on the bearing support and the steel ball that is installed between the retainer corresponding aperture is formed.In the existing this thrust ball bearing anti-rotation mechanism, steel ball is a contact with contacting of retainer, steel ball packing ring, and bearing support and moving scroll do not produce with the steel ball running orbit interferes, in the working procedure, the point of contact local deformation of steel ball and above-mentioned parts is a bit of circular arc under the effect of load, the pressure that bears is very big, and corresponding part life is shorter.When actual motion, steel balls numerous in the existing this thrust ball bearing anti-rotation mechanism are owing to the part processing that cooperates with it or the objective reality of assembly error, generally be that three less steel balls of the combined errors formation turning radius contact with the corresponding hole of retainer earlier, until one of them steel ball or after the through hole of the retainer of cooperation weares and teares with it, the another one steel ball just participates in contacting the anti-stop scroll rotation of retainer, when that is to say compressor operating, existing thrust ball bearing anti-rotation mechanism is because the existence of processing or assembly error, its steel ball that plays anti-rotation function mainly contains three, and the steel ball of the most of moving scroll spin moment of same carrying also only has three.Above feature makes the existing thrust ball bearing anti-rotation mechanism life-span short, uses the existing scroll compressor reliability of this kind anti-rotation mechanism corresponding relatively poor, and its reliability depends on the life-span of thrust ball bearing anti-rotation mechanism.
The model utility content
The purpose of this utility model is to provide a kind of scroll compressor, and this Anti-rotation Mechanism in Scroll Compressors operating life is improved significantly, and then has improved the reliability of scroll compressor.
For achieving the above object, the utility model adopts following scheme: include housing, bearing support, rotating shaft, fixed scroll, moving scroll, component such as magnetic clutch, be fixed with the bearing support retainer on the retainer attachment face of bearing support, be on the bearing support in the gasket groove of retainer attachment face inboard bearing support steel ball packing ring is housed, the retainer attachment face inner side edge of bearing support steel ball packing ring and bearing support is along having in each through hole that partly is exposed on the bearing support retainer, be fixed with the Moving plate retainer on the retainer attachment face of moving scroll, move on the step that is in the retainer attachment face outside on the scroll Moving plate steel ball packing ring is housed, the retainer attachment face outer side edge of moving scroll and Moving plate steel ball packing ring have in each through hole that partly is exposed on the Moving plate retainer, in every pair of corresponding through hole steel ball is housed between bearing support retainer and the Moving plate retainer, distance between the steel ball supporting face of the retainer attachment face of bearing support and bearing support steel ball packing ring causes the critical distance of interference greater than steel ball being moved between the two, and perhaps the distance between the steel ball supporting face of the retainer attachment face of moving scroll and Moving plate steel ball packing ring causes the critical distance of interference greater than steel ball being moved between the two.
By such scheme as seen, because the retainer attachment face of bearing support and the distance between the bearing support steel ball packing ring steel ball supporting face cause the critical distance of interference greater than steel ball being moved between the two, perhaps the distance between the steel ball supporting face of the retainer attachment face of moving scroll and Moving plate steel ball packing ring causes the critical distance of interference, bearing support or moving scroll just to have part that the running orbit of steel ball interfered greater than steel ball being moved between the two.Ball hardness wants hard a lot of with respect to bearing support or moving scroll hardness, when scroll compressor moves for the first time, the part that the running orbit of bearing support or moving scroll and steel ball is interfered constantly rolls down at steel ball, can be rolled out the desirable raceway that is sagged shape, do not exist the cooperating when raceway that is rolled by real work running track by steel ball work with steel ball and process or assemble equal error, so all steel balls run to the groove portion timesharing that rolls out and all can contact with raceway.The utility model is being interfered with the steel ball running orbit with steel ball packing ring adjacent portion is local by design bearing support or moving scroll, thereby draws the error free raceway of part after the preliminary operation of compressor.Greater than three, in the utility model, owing to roll the existence of raceway, the steel ball number of the moving scroll spin moment of carrying also can be greater than three as the steel ball number of designed thrust ball bearing anti-rotation mechanism.The increase of the steel ball number of the moving scroll spin moment of carrying can reduce the load in the ball retainer hole of each steel ball and correspondence thereof, increases the life-span of thrust ball bearing anti-rotation mechanism.In the existing design, steel ball number is generally 16, the scroll compressor scheme that adopts the utility model to provide, during compressor operating, the steel ball number of the moving scroll spin moment of carrying is much larger than three of existing general thrust ball bearing anti-rotation mechanism, so the spin moment that the spin moment that each steel ball carried in the utility model can steel ball bears in the existing thrust ball bearing anti-rotation mechanism, thus the life-span of the scroll compressor that the utility model provides can be increased dramatically relatively.
The utility model is rational in infrastructure, reliable performance, long service life.
