Technical Field

The invention belongs to the technical field of bearings, and particularly relates to an oil-bearing assembly and an assembling device thereof.

Background

The oil-retaining bearing is generally prepared by adopting a powder metallurgy process, and the sintered bearing has certain porosity inside, so that the oil-retaining bearing can ensure enough oil-retaining self-lubricating property. The oil-containing bearing is ideally lubricated in a hydrodynamic oil film lubrication state, and particularly, when the rotating shaft is static, lubricating oil is filled in the pores of the bearing; when the rotating shaft starts to run, the temperature is gradually increased through the mutual friction between the rotating shaft and the oil-containing bearing, and then the lubricating oil in the pores of the bearing gradually reduces the viscosity of the lubricating oil and seeps out of the pores to play a role in lubrication; when the rotating shaft runs at high speed, negative pressure is formed between the rotating shaft and the oil-containing bearing, and the lubricating oil is sucked out to form an oil film so as to reduce the friction between the rotating shaft and the oil-containing bearing.

In practical application, the existing oil-containing bearing is very easy to generate noise after running for a period of time, and the analysis reasons are as follows: 1. after long-time use, lubricating oil has certain loss (leakage, volatilization and other reasons), and an oil film formed by operation has a tendency of seeping back into pores of the oil-retaining bearing under the action of self weight, so that the bearing capacity of the oil film is reduced, and the contact of a friction pair between a rotating shaft and the oil-retaining bearing is influenced. 2. After long-term use, impurities such as dust and the like are brought into the area where the oil-containing bearing is located in the driving device, and after the impurities are mixed with lubricating oil in pores, the impurities are easily abraded or oil passages on the bearing are easily blocked.

Disclosure of Invention

In view of the above-mentioned deficiencies of the prior art, the oil-impregnated bearing assembly of the present invention solves the following technical problems: how to prolong the service life of the oil-retaining bearing and relieve the noise problem; the technical problem to be solved by the assembling device for the oil-containing bearing assembly is as follows: how to assemble the oil bearing assembly according to the invention according to a predetermined relative circumferential position.

In order to solve the technical problems, the invention adopts the following technical scheme:

an oil-containing bearing assembly comprises a bearing sleeve and a bearing, wherein the bearing comprises an inner layer section and an outer layer section connected to the outer surface of the inner layer section, and the porosity of the outer layer section is greater than that of the inner layer section;

the outer layer section is provided with a plurality of axial through holes which are annularly arranged along the outer layer section, the axial through holes axially penetrate through two end parts of the outer layer section, the outer layer section is also provided with radial through holes which are communicated with one end parts of the axial through holes, the radial through holes radially penetrate through the outer surface of the outer layer section, and the axial through holes and the radial through holes communicated with the axial through holes jointly enable the outer layer section to be provided with elastic plate sections;

the axial port is internally provided with filter cotton.

In application, the larger porosity can meet the requirement of sufficient oil supply capacity, but simultaneously, the larger porosity also easily enables oil between the bearing and the rotating shaft to permeate back into the pores of the bearing. Therefore, the balance between the self-lubricating performance and the oil film bearing performance is improved by adopting a multi-layer design. Specifically, the large pores of the outer layer can carry more oil, and in the operation process, the large pores can also absorb more oil under the action of negative pressure, and after lubricating oil forms an oil film between the bearing and the rotating shaft, the small pores of the inner layer can reduce the back-osmosis force of the oil film, so that the lubricating performance of the bearing is ensured.

In actual production, in order to avoid the fine scraps from blocking the pores, the working surface (inner layer segment) of the finished product of the oiliness bearing should be cut as little as possible. For this purpose, the invention selects to open axial through holes and radial through holes on the outer layer section, and filter cotton is installed in the axial through holes. When the impurities brought by the outside are attached to the bearing and flow to the inner layer section from the outer layer section along with the lubricating oil in a pore-forming manner, the impurities can be filtered by the filter cotton, so that the probability of blocking the inner layer section of the small pore-forming section is reduced, and the lubricating performance of the bearing is further ensured.

Wherein, the setting of radial opening not only can be convenient for assemble the filter pulp, still can abdicate in order to guarantee that the elastic plate section can compress tightly the filter pulp when the exogenic action elastic plate section.

Furthermore, the bearing sleeve comprises a bearing sleeve body, and the bearing sleeve body is provided with a connecting inner ring and a connecting outer ring positioned on the periphery of the connecting inner ring;

the inner wall surface of the connecting inner ring is provided with a plurality of clamping bulges which can be respectively matched with the elastic plate sections in a clamping way.

According to the invention, the connecting inner ring is used for mounting the bearing, and the bearing can be fixed by matching the inner surface of the connecting inner ring with the outer surface of the outer layer section; the bearing can be further positioned through the matching of the clamping bulge and the elastic plate section; meanwhile, the filter cotton can be tightly pressed in the axial through hole through the elastic plate section, so that the filter cotton can be prevented from accidentally moving to influence the filtering performance.

When the oil-retaining bearing is applied, the bearing sleeve is used for being connected with other parts so as to support the oil-retaining bearing.

Further, the radial thickness of the clamping protrusions is gradually increased along the circumferential direction of the connecting inner ring.

According to the invention, the pressing force of the elastic plate section can be adjusted by changing the relative circumferential position between the bearing sleeve and the bearing, so that the universal bearing has better universality. Specifically, when the area with the largest radial thickness of the clamping bulge is closer to the radial through hole, the pressing force on the elastic plate section is smaller; conversely, the larger the size. So that the setting can be carried out according to the requirements.
