Abstract
The utility model discloses a kind of boundary lubrication bearings, it is characterised in that：Low carbon steel substrate layer including being arranged to sleeve-like, the sintering of low carbon steel substrate layer inner surface has spherical copper powder layer, modified polyacetal wearing layer is covered on spherical copper powder layer, modified polyacetal wearing layer is equipped with several oil storage holes, and the modified polyacetal wearing layer outer surface covers one layer of copper/tin anti-corrosion electric coating；The embodiment not only enables the class bearing be not easy to be corroded in acid or alkaline environment, can effectively work normally, the storage oil mass for the oil storage aperture energy more capacity being equipped in bearing, extends bearing service life.
Description
Technical field
The utility model is related to a kind of bearing, more particularly to using the border of 3-layer composite material manufacture in self-lubricating bearing
Lubricate bearing.
Background technology
The boundary lubrication bearing of the 3-layer composite material manufacture used currently on the market is created by Britain Ge La West Asias company
System.It is using steel plate as matrix, is being sintered one layer of spherical bronze powder above, is finally applied on the surface of sinter layer and rolls one layer of modification and gather
Formaldehyde plastic layer rolls into sleeve-like, in the world as DX bearings with this 3-layer composite material.The characteristics of this kind of product is in axis
The working surface that holds is arranged the regular oil storage cave with spiral angle, lubricating grease is filled oil pit during assembling, with regard to that can play
More satisfactory boundary lubrication effect, it has preferable wearability, and with the continuous progress of science and technology, market is more thirsted for have
It is a kind of can not only meet boundary lubrication but also can under oil lubrication working condition the more superior novel product of friction and wear behavior
It replaces.
Utility model content
In view of the deficiencies of the prior art, the utility model provides a kind of boundary lubrication bearing.
To achieve the above object, the utility model provides following technical solution：
A kind of boundary lubrication bearing, the low carbon steel substrate layer including being arranged to sleeve-like, low carbon steel substrate layer inner surface are burnt
Spherical copper powder layer is had, modified polyacetal wearing layer is covered on spherical copper powder layer, modified polyacetal wearing layer is equipped with several
Oil storage hole, the modified polyacetal wearing layer outer surface cover one layer of copper/tin anti-corrosion electric coating.
Pass through above-mentioned technical proposal：By setting copper/tin anti-corrosion electric coating, the bearing apparatus on boundary lubrication bearing
Can be in acid or alkaline environment work, service life of equipment extends, and saves large number of equipment cost.
Preferably, the faying face of the copper/tin anti-corrosion electric coating and low carbon steel substrate layer, in molten condition, and copper/tin
Anti-corrosion electric thickness of coating is 0.008 millimeter.
Pass through above-mentioned technical proposal：Since copper/tin anti-corrosion electric coating is not to be simply covered in low carbon steel substrate layer,
But copper particle mutually wraps up two layers of binder course with iron and carbon particle in the molten state, tightly embedded jam-packed, therefore copper/tin is resistance to
Corrosion electroplated layer is not easy to fall off, cracking, extends the service life of boundary lubrication bearing
Preferably, it is equipped with wire netting in each oil storage hole.
Pass through above-mentioned technical proposal：Oil storage hole is equipped with wire netting, can not only prevent that impurity from entering oil storage hole, and can be with
The moiety by weight of support lubricating oil is depended on for lubricating oil, prevents oil leak.
Preferably, multiple apertures are equipped on each oil storage hole side wall, internal thread is set in each aperture.
Pass through above-mentioned technical proposal：Oil storage hole side wall is equipped with multiple apertures, and more lubricating oil can be stored in aperture,
Make boundary lubrication bearing usage time longer, effectively save the service time in boundary lubrication bearing, save cost of upkeep；
Internal thread depends on for lubricating oil simultaneously, reduces further the probability of oil leakage.
Description of the drawings
Fig. 1 is the present embodiment boundary lubrication bearing sectional view；
Fig. 2 is this reality embodiment boundary lubrication bearing stereogram.
Reference numeral：1st, low carbon steel substrate layer 11, spherical copper powder layer 12, modified polyacetal wearing layer 13, copper/tin are corrosion-resistant

Specific embodiment
Pass through Fig. 1 to Fig. 2.The utility model boundary lubrication bearing is further described.
A kind of boundary lubrication bearing, the low carbon steel substrate layer 11 including being arranged to sleeve-like, table in low carbon steel substrate layer 11
Face sintering has spherical copper powder layer 12, and modified polyacetal wearing layer 13, modified polyacetal wearing layer 13 are covered on spherical copper powder layer 12
Several oil storage holes 2 are equipped with, 13 outer surface of modified polyacetal wearing layer covers one layer of copper/tin anti-corrosion electric coating 14,
It can effectively use, will not be corroded in the environment of acid or alkali.
Further, the copper/tin anti-corrosion electric coating 14 makes with low carbon steel substrate layer 11 in the faying face of molten condition
Materials at two layers mutually insertion is firmly bundled together, and prevents copper/cracking of tin anti-corrosion electric coating 14 from coming off, and copper/tin is corrosion-resistant
14 thickness of electroplated layer is 0.008 millimeter.
Further, wire netting 21 is arranged in each oil storage hole 2, can not only prevents impurity from entering oil storage hole
2, and can oil leak be prevented with the moiety by weight of support lubricating oil.
Further, multiple apertures are equipped on 2 side wall of each oil storage hole, internal thread are set in each aperture, often
Lubricating oil can be stored in a aperture, and screw type internal thread can preferably adhere to lubricating oil, the program adds lubrication
Oily parking space, extends lubrication time, so as to extend the usage time of bearing.
Further, which also may be produced that bearing shell, thrust bearing, can also do a kind of friction of forming shape such as sliding block
Portion structure parts.
The above is only the preferred embodiment of the utility model, and the scope of protection of the utility model is not limited merely to
Above-described embodiment, all technical solutions belonged under the utility model thinking belong to the scope of protection of the utility model.It should refer to
