Abstract
The utility model relates to a kind of Eddy refrigeration compressor capable of preventing Self-rotation structure, comprise dynamic support ring [11], quiet support ring [3], double row ball [10], backing plate [2,4], movable orbiting scroll [1] is driven by eccentrically weighted shaft [6], the rolling groove that dynamic support ring [11] and quiet support ring [3] are formed and the double row ball [10] be placed in rolling groove limit the rotary motion of movable orbiting scroll [1] around its center, only make revolution translational motion; Double row ball [10] only moves in the rolling groove that dynamic support ring [11] and quiet support ring [3] are formed, and double row ball [10] two ends are by being pressed on backing plate [2,4]; Dynamic support ring [11] and quiet support ring [3] are fixed on movable orbiting scroll [1] and end cap [8] respectively by screw [7,9], and are compressed by backing plate [2,4]; Thus the lubricity realizing the spacing triple functions the utility model structure of axial thrust, tangential anti-rotation and radial direction is good, friction and wear is little, bearing capacity is strong, be applicable to high rotating speed, large overload Environmental Conditions under the user demand of large refrigerating capacity compressor; The double row ball of this structure not only serves and prevents movable orbiting scroll spinning motion, and axial gas power on all right balanced movable orbiting scroll, bears larger axial force, improves product work reliability.
Description
Technical field
Anti-rotation mechanism is the core component of swirl type cold compressor, is the key of the reliable and stable operation of compressor.
Background technique
Anti-rotation mechanism has the spacing triple functions of axial thrust, tangential anti-rotation and radial direction simultaneously, is the key realizing scroll compressor operation.The more current single row ball anti-rotation mechanism of the bearing capacity of double row ball anti-rotation mechanism is strong, and the large refrigerating capacity high speed compressor being applicable to transship greatly under environment, can meet the user demands such as military aircraft, civil aircraft, battlebus.
The utility model discloses a kind of anti-rotation mechanism of new structure, have employed biserial ceramic ball ball to support, there is the advantages such as structure is simple, reliability is high, high speed performance is good, bearing capacity is large, higher resistance to environment capacity and the requirements for life of Geng Gao can be obtained under the prerequisite ensureing product with compact structure, thus meet the user demand of the large refrigerating capacity high speed compressor under large overload environment.
Summary of the invention
Design that a kind of large bearing capacity, high speed performance are good, the anti-rotation mechanism of high reliability.
A kind of Eddy refrigeration compressor capable of preventing Self-rotation structure, comprise dynamic support ring, quiet support ring, double row ball, backing plate, movable orbiting scroll is driven by eccentrically weighted shaft, the rolling groove that dynamic support ring and quiet support ring are formed and the double row ball be placed in rolling groove limit the rotary motion of movable orbiting scroll around its center, only make revolution translational motion; Double row ball only moves in the rolling groove that dynamic support ring and quiet support ring are formed, and double row ball two ends are by being pressed on backing plate; Dynamic support ring and quiet support ring are fixed on movable orbiting scroll and end cap respectively by screw, and are compressed by backing plate; Thus realize the spacing triple functions of axial thrust, tangential anti-rotation and radial direction.
The dynamic support ring of double row ball supporting and quiet support ring.
Double row ball is ceramic ball.
Anti-rotation mechanism designed by the utility model have employed biserial ceramic ball ball and supports, there is the advantages such as structure is simple, reliability is high, high speed performance is good, bearing capacity is large, higher resistance to environment capacity and the requirements for life of Geng Gao can be obtained under the prerequisite ensureing product with compact structure, thus meet the user demand of the large refrigerating capacity high speed compressor under large overload environment.
Accompanying drawing illustrates:
Fig. 1 is structural representation of the present utility model.
Embodiment
A kind of Eddy refrigeration compressor capable of preventing Self-rotation structure, comprise dynamic support ring 11, quiet support ring 3, double row ball 10, backing plate 2,4, movable orbiting scroll 1 is driven by eccentrically weighted shaft 6, the rolling groove that dynamic support ring 11 and quiet support ring 3 are formed and the double row ball 10 be placed in rolling groove limit the rotary motion of movable orbiting scroll 1 around its center, only make revolution translational motion; Double row ball 10 only moves in the rolling groove that dynamic support ring 11 and quiet support ring 3 are formed, double row ball 10 two ends by being pressed in backing plate 2, on 4; Dynamic support ring 11 and quiet support ring 3 are respectively by screw 7, and 9 are fixed on movable orbiting scroll 1 and end cap 8, and by backing plate 2,4 compress; Thus realize the spacing triple functions of axial thrust, tangential anti-rotation and radial direction.
Double row ball 10 supports dynamic support ring 11 and quiet support ring 3.
Double row ball 10 is ceramic ball.
