Abstract
The utility model relates to a self-lubricating bearing steel bush, belongs to the technical field of machinery, and solves the problem in the prior art that a bearing cannot be used continuously under the situation of no lubricating oil. The self-lubricating bearing steel bush comprises a cylindrical body, wherein the body is made of stainless steel material, each of the inner side wall and the outer side wall of the body is provided with a lubricating hole, and a solid lubricating material is inlaid in the lubricating hole. According to the self-lubricating bearing steel bush, the inner wall and the outer wall of the body are provided with the lubricating holes and graphite material, the lubricating property of the inner wall and the outer wall of the steel bush can be guaranteed, and the inner wall of the body is also provided with an oil storage groove and an oil guide groove, so that the lubricating oil can be conveniently conveyed to any position of the steel bush, good lubricating effect of the bearing steel bush is ensued, and the steel bush still can run continuously for a period of time when the lubricating oil is used up.
Description
Technical field
The utility model belongs to field of mechanical technique, relates to a kind of bearing steel bushing, particularly a kind of self oiling bearing steel bushing.
Background technique
Self oiling bearing is by metallic matrix bearing load, the solid lubricant lubricate of special formulation.The features such as it is high that it has bearing capacity, shock-resistant, high temperature resistant, and selflubricating ability is strong, are specially adapted to heavy duty, low speed, back and forth or swing etc. be difficult to lubricated and form the occasion of oil film, the also etch of not water funk punching and other acid solution and washing away.Be widely used in metallurgy conticaster, rolled firm equipment, in mining machinery, mould, Hoisting Machinery, textile manufacturing machine, wind-powered electricity generation generating, boats and ships, steam turbine, water turbine, injection machine and device fabrication production line.
And having relatively high expectations for compressive strength, continuously service time longer working environment, and in the occasion of airtight difficult oiling, due to lubricated not smooth, if lubrication oil supply is not enough, can cause bearing running hot, kill and even scrap, affect the working life of machine.
Summary of the invention
The purpose of this utility model is to have the problems referred to above for existing technology, has proposed the bearing steel bushing that a kind of self-lubricating property is good.
The purpose of this utility model can realize by following technical proposal: a kind of self oiling bearing steel bushing, comprise tubular body, it is characterized in that, described body adopts stainless steel material to make, described body madial wall and outer side wall are provided with lubrication hole, in described lubrication hole, are inlaid with solid lubricant.
The composite material that inlay self-lubricating composite bearing adopts is a kind of novel anti-extreme pressure solid lubricant, metal substrate and the solid lubricant embedding in ground lubricated, consists of.In friction process, metal substrate has been born most loads.Through friction, the solid lubricant in lubrication hole shifts or reversion moves to rubbing surface, forms the solid transfer film of lubricated good, firm attachment uniform fold on rubbing surface, has significantly reduced fretting wear.With the carrying out of friction, the solid lubricant of embedding is constantly provided in rubbing surface, the good lubrication to friction pair while having guaranteed long-time running.
In above-mentioned a kind of self oiling bearing steel bushing, described solid lubricant is graphite.
In above-mentioned a kind of self oiling bearing steel bushing, described graphite is processed through immersion oil.After graphite material adopts immersion oil to process, graphite itself can absorb lubricant oil, and after steel bushing motion is overheated, due to the expansion of graphite material, graphite is understood outside oil impregnate, further improves the lubrication effect of steel bushing.
In above-mentioned a kind of self oiling bearing steel bushing, described inner body wall is circumferentially with oil storage tank along body.The effect of oil storage tank is to store lubricant oil, makes steel bushing in use keep lubricated.
In above-mentioned a kind of self oiling bearing steel bushing, described inner body wall is axially arranged with oil guide slot along body.Described oil guide slot plays and lubricant oil is delivered to the effect of steel bushing axial position from oil storage tank.
In above-mentioned a kind of self oiling bearing steel bushing, on described body, be positioned at oil guide slot and oil storage tank intersection is provided with oil inlet hole.Oil inlet hole is used for injecting lubricant oil, guarantees the lubricated of steel bushing inwall.
Compared with prior art, this self oiling bearing steel bushing is by arranging lubrication hole and graphite material at body inside and outside wall, guarantee the lubricity of steel bushing inside and outside wall, in inner body wall, offer oil storage tank and oil guide slot simultaneously, facilitate lubricant oil to be delivered to steel bushing arbitrary position, make bearing steel bushing high lubricating effect, even at steel bushing without still continuing to move a period of time under oil condition.
Accompanying drawing explanation
Fig. 1 is the sectional structure schematic diagram of this self oiling bearing steel bushing.
In figure, 1, body; 11, lubrication hole; 2, graphite; 3, oil guide slot; 4, oil storage tank; 5, oil inlet hole.
Embodiment
Be below specific embodiment of the utility model by reference to the accompanying drawings, the technical solution of the utility model is further described, but the utility model be not limited to these embodiments.
As shown in Figure 1, this self oiling bearing steel bushing, comprises tubular body 1, and body 1 adopts stainless steel material to make, and body 1 madial wall and outer side wall are provided with lubrication hole 11, are inlaid with graphite 2 in lubrication hole 11, and graphite 2 is processed through immersion oil.Graphite 2 itself has lubrication effect, and after immersion oil is processed, graphite 2 itself can absorb lubricant oil simultaneously, and after steel bushing motion is overheated, due to the expansion of graphite 2 materials, graphite 2 is understood outside oil impregnate, further improves the lubrication effect of steel bushing.
Body 1 inwall is circumferentially with oil storage tank 4 along body 1, and body 1 inwall is axially arranged with oil guide slot 3 along body 1.The effect of oil storage tank 4 is to store lubricant oil, makes steel bushing in use keep lubricated, and oil guide slot 3 plays and lubricant oil is delivered to the effect of steel bushing axial position from oil storage tank 4.On body 1, be positioned at oil guide slot 3 and oil storage tank 4 intersections are provided with oil inlet hole 5.Oil inlet hole 5, for injecting lubricant oil, guarantees the lubricated of steel bushing inwall.
This self oiling bearing steel bushing is by arranging lubrication hole 11 and graphite 2 materials at body 1 inside and outside wall, guarantee the lubricity of steel bushing inside and outside wall, at body 1 inwall, offer oil storage tank 4 and oil guide slot 3 simultaneously, facilitate lubricant oil to be delivered to steel bushing arbitrary position, make bearing steel bushing high lubricating effect, even at steel bushing without still continuing to move a period of time under oil condition.
Specific embodiment described herein is only to the explanation for example of the utility model spirit.The utility model person of ordinary skill in the field can make various modifications or supplements or adopt similar mode to substitute described specific embodiment, but can't depart from spirit of the present utility model or surmount the defined scope of appended claims.
