Description

Technical Field

[0001] The utility model relates to the technical field of air-conditioning compressors, and in particular to a novel axially compensated scroll disk. Background Art

[0002] When a scroll compressor is operating, the fixed scroll is fixed to the end cover, while the orbiting scroll can move slightly in the axial direction. In practice, the orbiting scroll's volute height, H1, and the fixed scroll's volute height, H2, should fit tightly together during assembly. However, because high-precision dimensions can't be guaranteed during mass production, a gap, X, occurs where X = H1 - H2. If gap X is too small, severe wear and a shortened lifespan will result. If gap X is too large, significant leakage will occur, resulting in poor compressor cooling performance.

[0003] Therefore, those skilled in the art provide a novel axially compensated scroll disk to solve the problems raised in the above background technology. Utility Model Content

[0004] The purpose of the utility model is to solve the shortcomings of the prior art and to propose a new type of axially compensated scroll disk.

[0005] In order to achieve the above purpose, the present invention adopts the following technical solutions:

[0006] A new type of axially compensated scroll plate includes a fixed scroll plate and a movable scroll plate, wherein the fixed scroll plate and the movable scroll plate are respectively equipped with a fixed scroll tooth and a movable scroll tooth that cooperate with each other, a vortex groove is opened at the bottom end of the movable scroll tooth, a first sealing strip is installed at the inner opening of the vortex groove, and an elastic rubber strip is installed between the first sealing strip and the top of the inner wall of the vortex groove.

[0007] Preferably, a groove is provided at the top end of the static scroll tooth, and a second sealing strip is embedded inside the groove.

[0008] Preferably, the cross-section of the elastic rubber strip is one of a circular structure, a U-shaped structure and an H-shaped structure.

[0009] Compared with the prior art, the beneficial effects of the present invention are:

[0010] The technical solution designed by the utility model is to process a vortex groove on the end face of the scroll tooth of the orbiting scroll, and place an elastic rubber strip and a first sealing strip respectively. The elastic rubber strip has a certain pre-compression amount. When the gap X is too small, the elastic rubber strip releases the compression amount and pushes the first sealing strip to move axially, so that the orbiting scroll and the fixed scroll fit within a reasonable range; when the gap X is too large, the elastic rubber strip continues to compress to ensure that the scroll teeth fit tightly, thereby realizing flexible automatic compensation.

[0019] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0020] Reference Figure 1-4 A novel axially compensated scroll comprises a fixed scroll 1 and an orbiting scroll 2. A fixed scroll tooth 3 and an orbiting scroll tooth 4 are mounted on the fixed scroll 1 and the orbiting scroll 2, respectively. A vortex groove 5 is formed at the bottom end of the orbiting scroll tooth 4. A first sealing strip 7 is mounted at the inner opening of the vortex groove 5. An elastic rubber strip 6 is mounted between the first sealing strip 7 and the top end of the inner wall of the vortex groove 5.

[0021] The technical solution adopted above is to process a vortex groove 5 on the end surface of the orbiting scroll tooth 4 in the orbiting scroll plate 2, and place an elastic rubber strip 6 and a first sealing strip 7 respectively. When the elastic rubber strip 6 is installed, the elastic rubber strip 6 has a certain pre-compression amount. When the gap X is too small, the elastic rubber strip 6 releases the compression amount and pushes the first sealing strip 7 to move axially, so that the orbiting scroll plate 2 and the fixed scroll plate 1 are matched within a reasonable range; when the gap X is too large, the elastic rubber strip 6 continues to compress to ensure that the scroll teeth are tightly matched, and the sealing strip 7 plays a sealing role during use.

[0022] A groove is formed at the top of the stationary scroll 3, and a second sealing strip 8 is embedded inside the groove;

[0023] The technical solution adopted above ensures the sealing between the end face of the stationary scroll 3 and the orbiting scroll 2 through the second sealing strip 8 .

[0024] Reference Figure 4-6 The cross section of the elastic rubber strip 6 is one of a circular structure, a U-shaped structure and an H-shaped structure;

[0025] In the technical solution adopted above, in specific applications, the shape of the elastic rubber strip 6 can be selected according to needs.

[0026] The above is only a preferred specific implementation method of the present invention, but the protection scope of the present invention is not limited to this. Any technician familiar with the technical field within the technical scope disclosed by the present invention can make equivalent replacements or changes based on the technical solution and utility model concept of the present invention, which should be covered by the protection scope of the present invention.
