Embodiment 1

[0048] Such as Figure 1 to Figure 6 As shown, the pump body assembly includes a structural member, a bearing cylinder 20 and at least one anti-friction structure 120. Among them, there are two structural parts. The bearing-type cylinder 20 is arranged between two structural parts. The bearing-type cylinder 20 includes an outer ring 24 and an inner ring 25 capable of rotating relative to the outer ring 24. At least one anti-friction structure 120 is provided on at least one end surface of the inner ring 25 facing the structural member to reduce the friction between the bearing cylinder 20 and the structural member.

[0049] The anti-friction structure 120 is arranged on the end surface of the inner ring 25 facing the structural member, so that no contact friction occurs between the inner ring 25 of the bearing cylinder 20 and the structural member.

[0050] During the operation of the pump body assembly, the inner ring 25 can rotate relative to the outer ring 24. Even if the inner...

Embodiment 2

[0073] The difference between the pump body assembly of the second embodiment and the first embodiment is that the structure of the friction reducing structure 120 is different.

[0074] Such as Figure 7 As shown, part or all of the end surface of the antifriction structure 120 away from the structure is provided with a protruding structure 121, and the end surface of the protruding structure 121 away from the structure is in contact with the bottom of the limiting ring groove 141. In this way, in the process of assembling the anti-friction structure 120 and the limiting ring groove 141, the protruding structure 121 can abut against the bottom of the limiting ring groove 141, and then the anti-friction structure 120 is assembled in an appropriate position, namely When the pump body assembly is not turned on or under the action of the mixture of high-pressure refrigerating machine oil and refrigerant, the antifriction structure 120 can be attached to the upper and lower flanges.

Embodiment 3

[0080] The difference between the pump body assembly of the third embodiment and the first embodiment is that the structure of the limiting part is different.

[0081] Such as Figure 8 to Figure 10 As shown, the limit part is a limit boss 142, and the antifriction structure 120 is a ring structure. The ring structure is sleeved on the limit boss 142 and the two have an interference fit. Part or all of the antifriction structure 120 is far away There is an axial gap 150 between the end surface of the structural member and the end surface of the inner ring 25 facing the structural member. In this way, the above arrangement can not only ensure that the surface of the antifriction structure 120 on the side away from the rolling element accommodating cavity 21 closely fits with the stop ring groove 141, but also ensure that the mixture of high-pressure refrigerating machine oil and refrigerant can enter the antifriction structure 120 far away The friction reducing structure 120 is p...

Abstract

The invention provides a pump body assembly and a compressor with the pump body assembly. The pump body assembly comprises two structural parts, a bearing type air cylinder arranged between the two structural parts and at least one antifriction structure; the bearing type air cylinder comprises an outer ring and an inner ring capable of rotating relative to the outer ring; at least one antifriction structure arranged on the inner ring faces the end face of the corresponding structural part, and friction between the bearing type air cylinder and the structural parts is reduced. The problems that in the prior art, the bearing type air cylinder in the pump body assembly is prone to wear, and the reliability of the pump body assembly is reduced are effectively solved.

Description

Technical field [0001] The present invention relates to the technical field of compressors, and in particular, to a pump body assembly and a compressor having the same. Background technique [0002] The suction and discharge structure of the traditional rotary vane compressor is arranged on the side of the cylinder, but due to the serious wear of the sliding vane head and the inner wall of the cylinder, the mechanical power consumption of the compressor is too large, and the overall energy efficiency is poor. Cause reliability problems such as abnormal wear. [0003] In the prior art, in order to solve the above problems, rolling elements and inner rings (similar to rollers) are added to the inner wall of the cylinder to form a bearing-type cylinder, so that the sliding motion between the head of the vane and the inner wall of the inner ring is converted into the inner ring and the rolling The rolling motion between the bodies reduces the mechanical power consumption of the pump b...
