Description

TECHNICAL FIELD

[0001] The present application belongs to the technical field of compressor manufacturing, and particularly relates to a dynamic scroll plate assembly, scroll compressor and air conditioner. BACKGROUND

[0002] The scroll compressor mainly comprises a dynamic scroll plate, a static scroll plate, an anti-rotation mechanism, a crankshaft and a bracket body. The bracket body is fixed on a shell, and the static scroll plate is fixed on the bracket body. When the compressor is working, the crankshaft drives the dynamic scroll plate to make a circular orbit movement around the center of the base circle of the static scroll plate. In order to avoid the rotation of the dynamic scroll plate during the operation of the compressor, an anti-rotation structure is usually used. The anti-rotation pin structure as one of the anti-rotation structures is fixed on the upper bracket, and a hole is formed on the back of the dynamic scroll plate corresponding to the position of the anti-rotation pin. An anti-rotation steel ring is installed in the hole to prevent the wear of the dynamic scroll plate. The anti-rotation pin can make a circular motion relative to the anti-rotation steel ring, and the anti-rotation steel ring can make a self-rotation motion in the hole. Since the anti-rotation steel ring is in a clearance fit with the dynamic scroll plate, the anti-rotation steel ring may fall off during the installation process of the dynamic scroll plate, which reduces the installation efficiency and even leads to the missing installation of the steel ring (the anti-rotation steel ring always falls off, which may lead to the failure to find and remedy in time, and finally the installation is not completed). Based on the foregoing deficiencies, the present application is proposed. SUMMARY

DETAILED DESCRIPTION

[0027] Reference is made to Figures 1 to 9 Fig. 1, according to an embodiment of the present application, a moving scroll assembly is provided, which comprises a moving scroll body 1, a plurality of holes 11 (specifically, cylindrical holes) are formed on the moving scroll body 1, specifically, a plurality of holes 11 are formed on the side of the moving scroll body 1 facing the compressor support 100 (also referred to as the upper support), an anti-rotation ring 2 is arranged in each hole 11, the anti-rotation ring 2 is in clearance fit with the hole wall of the hole 11, and a blocking structure is further included, which can prevent the anti-rotation ring 2 from being pulled out of the hole 11. In this technical solution, the blocking structure can effectively prevent the anti-rotation ring from being pulled out of the hole, thereby improving the assembly efficiency of the assembly.

[0028] As a specific embodiment of the blocking structure, the blocking structure comprises a first blocking ring plate 3 connected to the side of the orbiting scroll body 1 away from the fixed scroll, a plurality of first through holes 31 are formed on the first blocking ring plate 3, each first through hole 31 is arranged one-to-one corresponding to a plurality of the holes 11, and the diameter of the first through hole 31 is smaller than the outer diameter of the anti-rotation ring 2 and not less than the inner diameter of the anti-rotation ring 2. Further, the first blocking ring plate 3 and the orbiting scroll body 1 can be threadedly connected or riveted. In this technical solution, through the integrated structure of the first blocking ring plate 3, the anti-rotation ring 2 in the plurality of holes 11 can be blocked synchronously, and the assembly efficiency can be further improved, and the structure is also simpler.

[0029] Best of all, the first blocking ring plate 3 has a wear-resistant layer on at least the side away from the orbiting scroll body 1, which can be realized by carburizing process or by separately setting a corresponding wear-resistant material (wear-resistant plate), so as to reduce the wear of the mating surface between the orbiting scroll body 1 and the compressor support 100. Best of all, the part directly contacting the anti-rotation ring 2 and the compressor support 100 has the wear-resistant layer.

[0030] As described above, the orbiting scroll body 1 has a mating surface for cooperating with the compressor support 100, the hole of the hole 11 has a counterbore structure, the first blocking ring plate 3 has a flange ring plate 32 covering the mating surface, and the flange ring plate 32 and the first blocking ring plate 3 are connected as a whole through a connecting cylinder 33. At this time, only the side of the flange ring plate 32 facing the compressor support 100 is provided with a corresponding wear-resistant layer to realize the wear reduction requirement between the two, without the need for separately setting the wear-resistant sheet 104 in the prior art, so that the first blocking ring plate 3 can not only block the anti-rotation ring 2 from coming out, but also act as a wear-resistant structure.

[0031] As another specific embodiment of the blocking structure, the blocking structure comprises a plurality of second blocking ring plates 4, each second blocking ring plate 4 is connected one-to-one corresponding to the hole of the hole 11 and is located on the outside of the anti-rotation ring 2, a second through hole 41 is formed on the second blocking ring plate 4, the diameter of the second through hole 41 is smaller than the outer diameter of the anti-rotation ring 2 and not less than the inner diameter of the anti-rotation ring 2. Specifically, compared with the integrated first blocking ring plate 3, the second blocking ring plate 4 is a plurality of separate structures, which are arranged respectively for each hole 11, so as to save the corresponding material cost. The second blocking ring plate 4 can also be connected to the hole of the hole 11 by bolt connection or riveting connection.

In this structure, the anti-rotation ring 2 is not in contact with the inner wall of the hole 11, i.e. the orbiting scroll body 1, under the driving of the anti-rotation pin 103, i.e. the insertion cylinder 42 forms protection for the orbiting scroll body 1, thereby improving the service life of the orbiting scroll body 1.

[0033] As another specific embodiment of the blocking structure, the blocking structure comprises a magnetic attraction member 5 which is in the hole 11 to attract the anti-rotation ring 2. Specifically, for example, the magnetic attraction member 5 is a magnetic sheet which is embedded in the hole bottom of the hole 11 and can be effectively positioned in an interference fit, thereby achieving attraction and anti-disengagement of the anti-rotation ring 2. For another example, the hole bottom wall of the hole 11 has a corresponding magnetic attraction part which is composed of magnetic material and can also achieve attraction and anti-disengagement of the anti-rotation ring 2.

[0034] According to the embodiments of the present application, a scroll compressor is also provided, which comprises the orbiting scroll assembly. Figure 8 and 9 As shown in the drawings, the compressor support 100 is fixed on the casing 102, the fixed scroll 101 is fixed on the compressor support 100 and is pressed by the front end cover 105, the orbiting scroll body 1 is installed on the compressor support 100, and the fixed scroll 101 is engaged with the orbiting scroll body 1. When the compressor works, in order to make the orbiting scroll body 1 only make planar rotation relative to the fixed scroll 101, i.e. to prevent the orbiting scroll body 1 from rotating around itself, the anti-rotation pin structure is arranged between the compressor support 100 and the orbiting scroll body 1. The anti-rotation pin 103 is installed on the compressor support 100 in a pin hole, and the pin hole on the compressor support 100 is in interference fit with the anti-rotation pin 103.
