Abstract
The invention provides a radial flexible structure for a scroll compressor, which comprises a crank pin, a movable scroll shaft sleeve and a radial aligning mechanism, wherein the radial aligning mechanism comprises a round outer ring matched with the movable scroll shaft sleeve, and a mounting hole of which the center is matched with the crank pin. Compared with the prior art, the radial flexible structure for a scroll compressor is characterized in that the stability of the compressor can be improved, and movable and static scroll friction loss can be reduced.
Description
Technical field
The present invention relates to compressor, relate in particular to the radial compliance structure of scroll compressor.
Background technique
Existing scroll compressor radial compliance mechanism is an offset can regulate constantly, and as shown in Figure 1, core-regulating mechanism 1 can slide along the plane with respect to crank pin 2 constantly.
Can produce two problems like this: (1) compressor noise is big; (2) the radial seal power of the movable orbiting scroll of moving scroll centrifugal force, the formation of bent axle thrust and quiet whirlpool dish causes the engagement place friction power loss, reduces the compressor efficiency.
Summary of the invention
The object of the invention is exactly in order to provide a kind of radial compliance structure that can improve the stability of compressor and reduce the scroll compressor of dynamic and static vortex frictional loss.
In order to achieve the above object, the present invention has adopted following technological scheme: a kind of radial compliance structure of scroll compressor comprises crank pin, moving vortex axle sleeve; It is characterized in that; Also comprise radially core-regulating mechanism, this radially core-regulating mechanism comprise and circular outer ring and center and the crank pin installation holes for matching of moving vortex axle sleeve coupling; This mounting hole is can be when turbo compressor under normal state and fixedly clamping of crank pin; At the polygonal that runs under liquid hammer or the impurity entering situation with crank pin activity clamping, crank pin inserts in the mounting hole, is in fixing eccentric state when making turbo compressor under normal state; Running under liquid hammer or the impurity entering situation, the offset can regulate, the protection scroll is without prejudice.
The cross section that described crank pin is is semicircle shape, comprises circular arc limit and straight flange.
The mounting hole of described radially core-regulating mechanism is provided with the straight flange that is complementary with the crank pin straight flange; The side that this straight flange is relative is provided with the arc limit that is complementary with crank pin circular arc limit; During turbo compressor under normal state; Radially the straight flange of core-regulating mechanism and arc limit connect fixingly with the straight flange of crank pin and circular arc checkpost respectively, make scroll compressor be in fixing eccentric state.
Described radially core-regulating mechanism is installed on the crank pin through mounting hole; Both sides and crank pin coupling clamping before and after the mounting hole; The left and right sides is provided with the yielding cavity, and when in the swirl chamber of scroll compressor liquid refrigerants or impurity being arranged, moving vortex receives radial thrust drive core-regulating mechanism and moves; Crank pin is moved to making a concession cavity, change offset to dodge.
Compared with prior art, the present invention has designed and a kind ofly will fix radially core-regulating mechanism eccentric and that adjustable eccentric unites two into one, and it is installed on the crankshaft pin, and cylindrical cooperates with moving vortex axle sleeve.This is in fixing eccentric state when radially core-regulating mechanism makes turbo compressor under normal state; Running under the situation such as liquid hammer or impurity entering, the offset can regulate, the protection scroll is without prejudice.This radially core-regulating mechanism can improve the stability of compressor and reduce dynamic and static vortex frictional loss.

Embodiment
Shown in Fig. 2-3, a kind of radial compliance structure of scroll compressor comprises radially core-regulating mechanism 1, crank pin 2, moving vortex axle sleeve, and the cross section that crank pin 2 is is semicircle shape, comprises circular arc limit and straight flange.Radially core-regulating mechanism 1 comprises circular outer ring and the center and the crank pin installation holes for matching of mating with moving vortex axle sleeve.Radially the mounting hole of core-regulating mechanism 1 is provided with the straight flange that is complementary with the crank pin straight flange; The side that this straight flange is relative is provided with the arc limit that is complementary with crank pin circular arc limit; During turbo compressor under normal state (the bent axle sense of rotation is shown in arrow A among Fig. 1 and 2); Radially the straight flange of core-regulating mechanism and arc limit connect fixingly with the straight flange of crank pin and circular arc checkpost respectively, make scroll compressor be in fixing eccentric state.
Described radially core-regulating mechanism 1 is installed on the crank pin through mounting hole, both sides and crank pin coupling clamping before and after the mounting hole, and the left and right sides is provided with the yielding cavity; When in the swirl chamber of scroll compressor liquid refrigerants or impurity being arranged; Moving vortex receives radial thrust (shown in arrow B among Fig. 2) drive core-regulating mechanism and moves, and crank pin is moved to making a concession cavity, and the straight flange of crankpin 2 and circular arc limit move to the turning of mounting hole; The mounting hole of crankpin 2 and core-regulating mechanism 1 radially contact by fixing face when eccentric and changes line into and contact; Become adjustable eccentric, the offset can regulate, thus the protection scroll is without prejudice.
