Description

TECHNICAL FIELD

[0001] The utility model relates to scroll compressor technical field especially relates to a scroll compressor dynamic scroll anti -rotation structure. BACKGROUND

[0002] Scroll compressor has become one of the mainstream compressors in the field of refrigeration and air conditioning, which is widely used in various refrigeration and air conditioning applications with high energy efficiency, high reliability, low noise and vibration. Scroll compressor realizes the compression of gas by the multiple pairs of crescent-shaped working cavities formed by the mutual engagement of dynamic and static scrolls. In the working process, the dynamic scroll needs to revolve around the center of the base circle of the static scroll and make translational motion, and the phase of the dynamic scroll needs to be maintained to prevent it from rotating and damaging the engagement relationship between the scrolls. In actual product design, cross slip ring or anti-rotation pin is usually used to maintain the phase of the dynamic scroll. The anti-rotation mechanism of cross slip ring is the most commonly used phase maintaining mechanism in scroll compressor.

[0003] There is a small gap between the teeth of dynamic and static scrolls, and there is also a certain gap between the teeth of dynamic and static scrolls and the bottom plane due to the need for mechanical cooperation. Scroll compressor has multiple working cavities (usually 3 pairs) for simultaneous compression, and there is a pressure difference between adjacent working cavities, which causes the compressed gas to leak from the middle working cavity to the peripheral working cavity under the action of the pressure difference, resulting in a decrease in compressor efficiency. In order to compensate for the efficiency loss caused by the gap leakage, the current scroll compressor design adopts radial flexibility and axial flexibility design to reduce the leakage of refrigerant gas. Axial flexibility can be designed on the static scroll or the dynamic scroll. Axial flexibility on the static scroll may cause part of the axial force of the middle pressure cavity to be applied to the dynamic scroll, making the back of the dynamic scroll prone to wear. Therefore, it is an ideal design to place the axial flexibility on the dynamic scroll. However, due to the limitations of cross slip ring and drive crankshaft, the area of middle pressure cavity on the back of dynamic scroll is usually very limited, which is not enough to make the dynamic scroll float in the working process, resulting in the failure of flexibility.

[0004] For example, the compressor mechanism of a scroll compressor and the scroll compressor disclosed in Chinese Patent No. CN 210565070 U include a fixed scroll component and a movable scroll component that are engaged with each other to define a working fluid chamber including a suction chamber, the movable scroll component has an end plate, the fixed scroll component has a key groove, an anti-rotation device is coupled to the fixed scroll component and the movable scroll component, respectively, so that the movable scroll component can rotate relative to the fixed scroll component, the anti-rotation device has a key coupled to the key groove, and a lubrication channel is arranged in the end plate, wherein the position of an oil outlet hole of the lubrication channel is arranged such that, in one rotation of the movable scroll component, the oil outlet hole is alternately in fluid communication with the key groove and the suction chamber, or the oil outlet hole is always in fluid communication with the key groove and is in fluid communication with the suction chamber in a part of the angle in one rotation of the movable scroll component.

DETAILED DESCRIPTION

[0029] The skilled in the art can easily understand other advantages and effects of the present application from the content disclosed in the specification.

[0030] The following describes the preferred embodiment of the anti-rotation structure of the dynamic scroll of the scroll compressor.

[0031] Embodiment 1

[0032] The scroll compressor has become one of the mainstream compressors in the field of refrigeration and air conditioning with the advantages of high energy efficiency, high reliability, low noise and vibration. The gas compression is realized by the multiple pairs of crescent-shaped working cavities formed by the mutual engagement of the dynamic and static scrolls. In the working process, the dynamic scroll needs to make a revolution and translation motion around the center of the base circle of the static scroll, and the phase of the dynamic scroll is maintained so as to prevent the self-rotation and damage the engagement relationship between the scrolls. In the prior art, the cross slip ring or the anti-rotation pin is usually used to maintain the phase of the dynamic scroll. However, the anti-rotation pin will limit the position of the dynamic scroll in the radial direction due to the matching motion relationship between the pin and the bearing seat, so that the gap between the dynamic and static scrolls cannot be eliminated even if the radial flexibility is designed, and the efficiency of the compressor is reduced. The cross slip ring limits the relative rotation of the dynamic and static scrolls, and the dynamic scroll needs to be designed axially flexible to prevent wear and tear. However, due to the limitation of the cross slip ring and the driving crankshaft, the area of the middle pressure cavity arranged on the back surface of the dynamic scroll is very limited. To solve the problem of insufficient support area of the axial flexible design on the dynamic scroll, the anti-rotation structure of the scroll compressor dynamic scroll is arranged on the dynamic scroll, which reduces the axial leakage problem in the working process of the scroll and improves the compression efficiency of the scroll compressor.
