Abstract
The invention provides a kind of radial compliance structure of scroll compressor, comprise crank pin, dynamic vortex axle sleeve, also comprise radial core-regulating mechanism, this radial core-regulating mechanism comprises the circular outer ring of mating with dynamic vortex axle sleeve, and the mounting hole that center is mated with crank pin.Compared with prior art, the present invention can improve the stability of compressor and reduce dynamic and static vortex frictional loss.
Description
Technical field
The present invention relates to compressor, particularly relate to the radial compliance structure of scroll compressor.
Background technique
Existing scroll compressor radial compliance mechanism is that the offset moment is adjustable, and as shown in Figure 1, core-regulating mechanism 1 can slide along the plane moment relative to crank pin 2.
Two problems can be produced like this: (1) compressor noise is large; (2) radial sealing force that orbiter centrifugal force, crank thrust are formed movable orbiting scroll and quiet whirlpool are coiled causes engagement place friction power loss, reduction compressor efficiency.
Summary of the invention
Object of the present invention, exactly in order to provide the radial compliance structure of a kind of stability that can improve compressor and the scroll compressor reducing dynamic and static vortex frictional loss.
In order to achieve the above object, present invention employs following technological scheme: a kind of radial compliance structure of scroll compressor, comprise crank pin, dynamic vortex axle sleeve, it is characterized in that, also comprise radial core-regulating mechanism, this radial core-regulating mechanism comprises the circular outer ring of mating with dynamic vortex axle sleeve, with the mounting hole that center is mated with crank pin, this mounting hole for can when turbo compressor under normal state and crank pin fix clamping, run into liquid hammer or impurity enter situation under with the polygonal of crank pin activity clamping, crank pin inserts in mounting hole, make to be in fixing eccentric state during turbo compressor under normal state, running under liquid hammer or impurity enters situation, offset is adjustable, and protection scroll is without prejudice.
The cross section of described crank pin is semicircle shape, comprises arc-shaped edges and straight flange.
The mounting hole of described radial core-regulating mechanism is provided with the straight flange matched with crank pin straight flange, the side that this straight flange is relative is provided with the arc-shaped side matched with crank pin arc-shaped edges, during turbo compressor under normal state, the straight flange of radial core-regulating mechanism and arc-shaped side connect and fix with the straight flange of crank pin and arc-shaped edges respectively, make scroll compressor be in fixing eccentric state.
Described radial core-regulating mechanism is arranged on crank pin by mounting hole, before and after mounting hole, clamping is mated with crank pin in both sides, the left and right sides is provided with yielding cavity, when having liquid refrigerants or impurity in the swirl chamber of scroll compressor, dynamic vortex is subject to radial thrust and drives core-regulating mechanism to move, crank pin is moved to yielding cavity, changes offset to dodge.
Compared with prior art, the present invention devises a kind of radial core-regulating mechanism fixing bias and adjustable eccentric united two into one, and it is arranged on crankshaft pin, and cylindrical coordinates with dynamic vortex axle sleeve.This radial core-regulating mechanism makes to be in fixing eccentric state during turbo compressor under normal state; Running in the situations such as liquid hammer or impurity enter, offset is adjustable, and protection scroll is without prejudice.This radial core-regulating mechanism can improve the stability of compressor and reduce dynamic and static vortex frictional loss.

Fig. 2 to be the radial compliance structure of scroll compressor of the present invention be fixing eccentric time schematic diagram;
The schematic diagram that Fig. 3 is the radial compliance structure of scroll compressor of the present invention when being adjustable eccentric.
Embodiment
Embodiment 1
As Figure 2-3, a kind of radial compliance structure of scroll compressor, comprises radial core-regulating mechanism 1, and crank pin 2, dynamic vortex axle sleeve, the cross section of crank pin 2 is semicircle shape, comprises arc-shaped edges and straight flange.Radial core-regulating mechanism 1 comprises the circular outer ring of mating with dynamic vortex axle sleeve, and the mounting hole that center is mated with crank pin.The mounting hole of radial core-regulating mechanism 1 is provided with the straight flange matched with crank pin straight flange, the side that this straight flange is relative is provided with the arc-shaped side matched with crank pin arc-shaped edges, during turbo compressor under normal state (crank rotation direction is as shown in arrow A in Fig. 1 and 2), the straight flange of radial core-regulating mechanism and arc-shaped side connect and fix with the straight flange of crank pin and arc-shaped edges respectively, make scroll compressor be in fixing eccentric state.
Described radial core-regulating mechanism 1 is arranged on crank pin by mounting hole, before and after mounting hole, clamping is mated with crank pin in both sides, the left and right sides is provided with yielding cavity, when having liquid refrigerants or impurity in the swirl chamber of scroll compressor, dynamic vortex is subject to radial thrust (as designated by arrows b in fig) and drives core-regulating mechanism to move, crank pin is moved to yielding cavity, the straight flange of crankpin 2 and arc-shaped edges move to the turning of mounting hole, the mounting hole of crankpin 2 and radial core-regulating mechanism 1 is contacted by face when fixing bias and changes linear contact lay into, become adjustable eccentric, offset is adjustable, thus protection scroll is without prejudice.
