Problems solved by technology

In order to make up for the aforementioned deficiencies, the usual practice of compressor manufacturers is to enlarge the axial design gap between the rollers and the upper and lower flanges (or partitions), but this method has the disadvantage of low energy efficiency of the compressor

Embodiment Construction

[0026] see in conjunction Figure 1 to Figure 4 As shown, according to the embodiment of the present invention, a roller is provided, including a roller body 1, at least one axial end of the roller body 1 is provided with a first annular groove 11, and the first annular groove 11 is arranged along the The roller body 1 extends radially outward to form a corresponding ring wall 12 . In this technical solution, on the one hand, due to the setting of the first ring groove 11 at the end of the roller body, the thickness of the ring wall corresponding to it is reduced, so that the deformation of the ring wall in the direction of force is more accurate. easily (that is, the rigidity of the ring wall 12 is reduced and the flexibility is improved), thereby reducing the degree of wear between the free end surface of the ring wall and the flange or partition in contact with it; on the other hand, in the prior art, the roller In the type compressor, the head of the sliding vane is in co...

Abstract

The invention provides a roller, a pump body assembly and a compressor. Wherein the roller includes a roller body, at least one axial end of the roller body is provided with a first annular groove, and the first annular groove extends outward along the radial direction of the roller body to form a corresponding annular wall . The invention provides a roller, a pump body assembly, and a compressor. At least one end of the roller is provided with a first ring groove, so that the corresponding ring wall has a large deformation capacity, which can effectively reduce the degree of wear, and at the same time, the first ring The grooves can also effectively reduce the transfer of frictional heat from the ends of the rollers to the middle region of the roller body, thereby effectively reducing the axial expansion of the rollers.

Description

technical field [0001] The invention belongs to the technical field of compressor manufacturing, and in particular relates to a roller, a pump body assembly and a compressor. Background technique [0002] The roller of the rotor compressor is one of the core components of the compressor pump body. During the operation of the compressor, it has relative motion friction with the end faces of the upper and lower flanges (or the end faces of the flange and the partition) and the head of the sliding vane at the same time, resulting in As the temperature of the roller rises, large thermal deformation occurs in the axial direction, which reduces the axial gap between the roller and the mating end faces on both sides (the end faces of the upper and lower flanges or the end faces of the flange and the diaphragm), and finally leads to the Severe wear occurs on the end face of the flange or the end face of the separator. In order to make up for the aforementioned deficiencies, the com...
