Embodiment 2

[0074] This embodiment is a further improvement made on the basis of Embodiment 1, as Figure 6-7 , preferably, also includes an upper oil storage tank 21 arranged on the upper flange 2, the upper oil storage tank 21 communicates with the oil inlet hole 20c of the bearing rolling body, and also communicates with the oil inlet passage for the bearing lubrication 20b is connected. Through the upper oil storage tank set at the above position, the oil passing through the bearing lubricating oil inlet channel can enter the upper oil storage tank for storage before entering the bearing rolling element oil inlet hole, so as to realize the oil storage when the amount of oil is too much Function, when the amount of oil is too small, the lubricating oil can be released through the oil storage tank, so as to ensure the good lubrication and cooling effect of the rolling bearing and improve the performance of the compressor.

[0075] Preferably, the upper oil storage tank 21 is located ax...

Embodiment 3

[0077] Such as Figure 15-16 , this embodiment is a further improvement made on the basis of Embodiment 1 and / or 2, preferably, a gasket 8 is also provided between the upper flange 2 and the rolling bearing 3, and the gasket 8 is provided with a plurality of oil guide holes 81 along the axial direction of the main shaft, and the plurality of oil guide holes 81 are arranged along the circumferential direction of the main shaft, and can communicate with the oil inlet hole 20c of the rolling body of the bearing and the rolling body 33 . Before the gasket is added, the lubricating oil directly enters the rolling element 33 of the bearing cavity through the oil inlet hole 20c of the upper flange bearing rolling element. In principle, the oil is supplied from one point to the entire bearing cavity, so the oil supply position is relatively fixed, although The inner ring is rotating, but for the entire bearing cavity, the temperature difference of the oil temperature is relatively la...

Embodiment 4

[0080] This embodiment is a further improvement made on the basis of Embodiment 1-3, preferably, it also includes a lower flange 4, and a lower oil groove that can communicate with the rolling body is also opened on the lower flange 4 41 , through the lower oil groove 41 , the oil can be led out from the lower flange 4 , or the oil can be led out from the rolling bearing 3 . Through the lower oil groove provided on the lower flange, the oil can be transported and diverted, and the lubricating oil can be discharged into the shell of the compressor, thereby realizing the recovery and recycling of the oil.

[0081] Then, after the lubricating oil passes through the rolling elements, it will flow to the lower flange due to its own gravity and oil pressure, and concentrate on the lower oil groove of the lower flange (such as Figure 8 As shown), the lower oil groove directly leads to the outside of the pump body, and the oil will flow out to the casing oil pool along with the oil o...

Abstract

The invention provides an oil channel structure of a compressor and the compressor. The oil channel structure comprises a main shaft (1), an upper flange (2) and a rolling bearing (3). An air cylindercavity for compression is defined in the rolling bearing (3). The rolling bearing (3) comprises a rolling body (33). The inner portion of the main shaft (1) is provided with a main shaft oil hole (10). An upper oil groove (20) is formed in the upper flange (2). The upper oil groove (20) communicates with the main shaft oil hole (10) and can guide oil into the rolling body (33) so as to lubricatethe rolling body (33). By the adoption of the oil channel structure of the compressor, oil in the main shaft oil hole of the compressor can be effectively guided into the rolling body part of the rolling bearing through the upper flange, the rolling body is lubricated and cooled, so that heat generated due to friction of the rolling body can be dissipated out in time, the temperature of the bearing is prevented from rising, and wear is reduced; and in this way, the energy efficiency value of the compressor is improved, and normal operation of the compressor is guaranteed.

Description

technical field [0001] The invention belongs to the technical field of compressors, and in particular relates to an oil circuit structure of a compressor and the compressor. Background technique [0002] The suction and exhaust structures of the existing traditional rotary vane compressors are mainly arranged on the side of the cylinder, but due to the severe wear of the head of the sliding vane and the inner wall of the cylinder, the mechanical power consumption of the compressor is too large, the overall energy efficiency is poor, and even cause serious damage. Reliability issues such as abnormal wear and tear. [0003] Korean Patent Application No. KR1020100076562 patent discloses a rolling bearing scheme: by adding a rolling body and an inner ring (similar to a roller) structure on the inner wall of the cylinder, the relative sliding between the head of the slide plate and the inner wall of the inner ring is guaranteed to be transformed into the contact between the inner...
