Abstract
The utility model discloses a kind of sliding bearing, aim to provide that a kind of noise is enough low, sufficiently long sliding bearing of life-span.The utility model comprises bearing support (1), described bearing support (1) contains the cylindrical body of oiling agent for internal capillary, described bearing support (1) is axially arranged with the axis hole (2) of perforation, the outer rim of described bearing support (1) is axially arranged with circumferentially uniform mounting groove (3) of at least two edges, and described axis hole (2) is the shoulder hole that the two ends diameter is big, mid diameter is little.The utility model can be widely used in field of bearings.
Description
Technical field
The utility model relates to a kind of sliding bearing, particularly a kind of radially carrying sliding bearing of internal capillary oil-containing.
Background technique
Bearing is mechanical parts commonly used of going up revolving meber in order to bearing journal or axle, can be divided into rolling friction bearing (rolling bearing) and sliding friction bearing (sliding bearing) according to the working principle of bearing.If can form lubricating film separates movement pair surface, then force of sliding friction can reduce greatly on the sliding bearing surface, because therefore not directly contact of movement pair surface has also avoided wearing and tearing.The bearing capacity of sliding bearing is big, and rotating accuracy height, lubricating film have the shock resistance effect, therefore, obtains to use widely on engineering.According to the direction difference of bearing load, sliding bearing is divided into radial sliding bearing and thrust slide bearing, the stressed center line perpendicular to axle of radial sliding bearing.
At present, just more and more general employing oil-containing sliding bearing on as the micro-machine in the industry such as various household electrical appliances such as electric fan, electric drill, electric tool, automobile, electronics, the outer densification of this bearing is in case leak-stopping oil, body interior has a lot of micropores with soaking by lubricating oil, the axis hole internal surface have much can seepage lubricant oil micropore, in use, the lubricant oil of impregnation forms the skim oil film at the axis hole internal surface and lubricates realizing.This oil-containing sliding bearing vibration influence that is hit is little, and noise is more much lower than rolling bearing, and its shortcoming is the life-span deficiency, and reason is that lubricant oil can run off from the hole of bearing and volatilization.In order to improve the life-span of bearing, the oil-impregnated bearing that oil storage space comes the supplemental lubrication agent to run off is set in bearing now in addition, its deficiency is: if adopt lubricating grease oiling agent as a supplement, because the particle size of the soap base of lubricating grease is greater than the pore-size of bearing, the hole of bearing is blocked in meeting, influences the characteristic of oil-impregnated bearing itself; If adopt lubricant oil oiling agent as a supplement, because oil mass is more, " getting rid of oil " phenomenon can appear, cause other component contamination even short circuit.In addition, (in the computer CPU fan) is lower to the requirement of noise in some application, and the noise that present bearing operation produces still can not meet the demands.
So existing technology has the following disadvantages: noise is low inadequately, the life-span falls short of.
The model utility content
Technical problem to be solved in the utility model is the deficiency that overcomes on the prior art, provides that a kind of noise is enough low, sufficiently long sliding bearing of life-span.
The technological scheme that the utility model adopted is: the utility model comprises bearing support, described bearing support is the cylindrical body that internal capillary contains oiling agent, described bearing support is axially arranged with the axis hole of perforation, the outer rim of described bearing support is axially arranged with circumferentially uniform mounting groove of at least two edges, and described axis hole is the shoulder hole that the two ends diameter is big, mid diameter is little.
Described bearing support adopts powdered metallurgical material and macromolecule blending material to make, and oiling agent adopts fluorine class oil.
The beneficial effects of the utility model are: because the outer rim of bearing support described in the utility model is axially arranged with circumferentially uniform mounting groove of at least two edges, described axis hole is that the two ends diameter is big, the shoulder hole that mid diameter is little, described mounting groove helps installing and fixing of bearing, described mounting groove has the effect of accelerating heat radiation concurrently simultaneously, the shoulder hole structure of described axis hole can store the lubricant oil that a part may run off, the lubricant oil of storage is replenished when oil film is imperfect to continuous, complete, lasting oil film, avoided oily loss, so the utility model installation is more convenient, noise is enough low, the life-span long enough;
Because bearing support described in the utility model adopts powdered metallurgical material and macromolecule blending material to make, oiling agent adopts fluorine class oil, macromolecular material forms chemisorption with powdered metallurgical material under the uniform temperature condition, between powdered metallurgical material and oiling agent, form the medium that connects the two, help making that oiling agent is stable lasting keeps and do not run off, not flammable, low volatilization that fluorine class oil has can long-actingly be lubricated, so the utlity model has better noise, life performance.
Description of drawings
Fig. 1 is a side structure schematic representation of the present utility model;
Fig. 2 is the A-A cross-sectional view of sliding bearing shown in Figure 1.
Embodiment
As shown in Figure 1 and Figure 2, the utility model comprises bearing support 1, described bearing support 1 contains the cylindrical body of oiling agent for internal capillary, described bearing support 1 is axially arranged with the axis hole 2 of perforation, the outer rim of described bearing support 1 is axially arranged with circumferentially uniform mounting groove 3 of two edges, described axis hole 2 is the shoulder hole that the two ends diameter is big, mid diameter is little, and described bearing support 1 adopts powdered metallurgical material and macromolecule blending material to make, and oiling agent adopts fluorine class oil.The axial length of described bearing support 1 is that 8mm, external diameter are 8mm, described mounting groove 3 is the semi-circular groove of section radius 0.5mm, the shoulder hole of described axis hole 2 is of a size of: the diameter of two ends macropore is 5mm, the degree of depth is 0.8mm, and the diameter of middle aperture is 3mm.The concrete quantity of above-described mounting groove 3 and the index of every concrete size only are a specific embodiment, can certainly adopt other quantity and concrete size.
The utility model can be widely used in field of bearings.
Under the situation that does not break away from the present utility model thought, all application the utility model specifications and accompanying drawing content and the various equivalences of being done change, and all reason is with being contained in the claim scope of the present utility model.
