Abstract
The utility model discloses a minimized scroll compressor for car aiming at the problem of oversized radial compensation mechanism of existing scroll compressor. The utility model changes connection mode in radial compensation mechanism from existing connection between pin axle and pin hole into connection between crescent boss of eccentric sleeve and crescent concave stage of eccentric shaft. This reduces the size of radial compensation mechanism greatly, reduces radial size of driven plate and fixed bead ring, and is beneficial for minimization of radial size of car used scroll compressor.
Description
Technical field
The utility model relates to a kind of Vehicular air-conditioner compressor, especially a kind of vortex type automobile air conditioner compressor, specifically a kind of miniaturization vortex type automobile air conditioner compressor.
Background technique
At present, scroll compressor is extensively adopted by automotive industry with its good performance and smaller volume.
As everyone knows, installing space on the automobile and highly limited, therefore automobile production enterprise wishes that generally the air condition compressor volume of institute's adapted is the smaller the better, at first to consider therefore when especially setting height(from bottom) then is apolegamy, therefore for compressor manufacturing industry, how compresses machine overall volume, especially radial dimension just seem very important under the prerequisite that guarantees discharge capacity, are the preconditions of winning the market.
According to the knowledge of the applicant, the radial dimension of the Moving plate of existing scroll compressor is excessive to be the principal element that causes the compressor volume excessive, and the size of Moving plate is relevant with selected bearing, bearing is relevant with the size of bearings mounted eccentric bushing again, and the size of eccentric bushing is relevant with radial compensation mechanism again.In order to make eccentric bushing when rotating, realize certain radial compensation, between the eccentric shaft on eccentric bushing and its bent axle of installation certain relatively rotating should be arranged, impact and noise when starting to reduce Moving plate with bent axle.Existing eccentric bushing all is connected with a bearing pin, meanwhile, on bent axle, then be provided with the pin-and-hole that an aperture is slightly larger than the bearing pin external diameter, both led in the pin-and-hole on the bearing pin insertion bent axle on the eccentric bushing and prevented relatively rotating between eccentric bushing and the eccentric shaft, can make again and do relatively rotating of trace between the two, when realizing the bent axle starting and balancing weight play compensating action simultaneously, therefore the bearing pin in the existing this radial compensation mechanism and the Placement of pin-and-hole make the oversize of the size of the eccentric shaft on the bent axle and eccentric bushing, have limited the realization of compressor miniaturization target.
Summary of the invention
The purpose of this utility model is at the excessive problem of radial compensation mechanism size in the existing scroll compressor, has designed a kind of vortex type automobile compressor that has miniaturization radial compensation mechanism.
The technical solution of the utility model is:
A kind of miniaturization vortex type automobile air conditioner compressor, comprise casing 1, dynamic disk component 2, quiet dish assembly 3, crankshaft group 4, eccentric bushing 5, clutch pack 6, preceding cap assemblies 7, before cap assemblies 7 link to each other with power intake on the casing 1, dynamic disk component 2, quiet dish assembly 3, be installed in the casing 1, one end of crankshaft group 4 is arranged in casing 1, the other end is arranged in preceding cap assemblies 7, clutch pack 6 is installed on the preceding cap assemblies 7, crankshaft group 4 is arranged on the end of casing 1 eccentric bushing 5 is installed, dynamic disk component 2 a not end of ribbon line links to each other with eccentric bushing 5 by bearing 8, the other end insert be fixed on casing 1 quiet dish assembly 3 in, between dynamic disk component 2 and preceding cap assemblies 7, steel ball 9 is installed, steel ball 9 is positioned in the casing 1 by deciding pearl circle 10, it is characterized in that on the relative end of eccentric bushing 5 and crankshaft group 4, being provided with crescent shape boss 501, on the cylindrical root 402 of the eccentric shaft 401 of crankshaft group 4, be provided with the crescent shape concave station 401 that matches with described crescent shape boss 501, and the chord length of described crescent shape boss 501 is greater than the chord length of crescent shape concave station 401.Wherein:
Eccentric shaft 401 is made up of cylindrical root 402, cone 403 and cylindrical bar body portion 404, is provided with conical bore 502 that matches with described cone 403 and the cylindrical hole 503 that matches with described cylindrical bar body portion 404 in the described eccentric bushing 5.
The utlity model has following advantage:
1, the utility model helps reducing the radial dimension of compressor for the vortex type automobile compressor has found a kind of simple approach of miniaturization under the prerequisite of same displacement, helps improving competitiveness of product.
2, method is simple, and structure is more succinct, makes more conveniently, saves cost.
3, owing to reduced the size of eccentric bushing, make the size of eccentric shaft also can correspondingly reduce, with the time also can reduce to be installed in simultaneously the size of the balancing weight on the bent axle, the inertia of complete machine moving element is reduced, help reducing the vibration and the noise of complete machine.
