Abstract
The utility model relates to a composite bearing made of metal and non-metal, comprising a non-metal substrate and a metal external layer which are connected with each other, wherein, the non-metal substrate is formed by mixed weaving synthetic fiber yarn in the form of plain waves or satin waves. The composite bearing has simple structure, is easy to be formed and processed as well as manufactured, can be made into sliding bearings of various shapes according to the requirement, and has strong bearing force, good rigidity, high strength and hardness, excellent self-lubrication performance, wearability and excellent anti-pollution performance and anti-corrosion performance.
Description
Technical field
The utility model relates to composite bearing, specifically, is a kind of metal species material and the compound composite bearing of non-metal kind material.
Background technique
The bearing of existing market is divided into two kinds of metal species and non-metal kinds.The material of metal species bearing has steel, copper, powder metallurgy etc.Non-metal kind has nylon, polyether-ether-ketone, polyimide, polyoxymethylene etc.They all have pluses and minuses separately, the metal bearing good rigidly, and bearing capacity is big, but friction factor is big, impaired easily to friction pair.Nonmetallic bearing then is that plasticity is good, and friction factor is little, but poor rigidity, easy deformation, and bearing capacity is little, and wear resistance is also poor.
Summary of the invention
Purpose of the present invention just provides a kind of metal species material and the compound composite bearing of non-metal kind material, and its bearing capacity is big, good rigidly, and also friction factor is little, does not damage friction pair.
Composite bearing of the present utility model, it comprises nonmetal layer and the metal outer that is connected.
Working mechanism of the present utility model: the general and metal rotating shaft of nonmetal layer of the present utility model forms a pair of spin friction pair.In the running-in stage, because there is certain roughness on the rotating shaft surface, have different " protruding peak " and " trench ", exaggerating just looks like the nonmetal internal surface generation ablation of the same composite bearing of file, and the non-metal powder major part that grinding is got off is filled in the trench.Along with the lasting rotation of rotating shaft, the powder cumulant that grinding is got off constantly increases, and fills more trench." grinding---fill " process continues to carry out, and causes that all trench have all filled up little bits on the rotating shaft surface.Under the rotating shaft action of gravity, little bits are compacted in the trench, make the rotating shaft intimate adhere to a skim, and form the continuous light sliding surface.This process has been finished the part " transfer " of bearing inner surface, and the result of transfer is: become mutual friction mutually between a kind of material by metal and nonmetal two kinds of materials.Because nonmetal good self-lubricating property; therefore at the later working stage of running-in, the wear extent of bearing inner surface drops to an extremely low level thereupon, thereby surface of friction pair is protected; alleviate the wearing and tearing on bearing and rotating shaft surface greatly, prolonged operating life.
Described nonmetal layer is mixed to knit by two kinds of synthetic fiber yarns and forms.Synthetic fiber are the general designations with the synthetic macromolecular compound chemical fibre that to be raw material make through processing, are main raw material with oil, rock gas, coal etc. promptly, make monomer with the method for organic synthesis, and polymerization is after spinning processing and the fiber made.Mix to knit and to adopt plain weave or satin weave mode.Synthetic fiber, mixed knitting all belong to prior art, no longer describe.
Two kinds of synthetic fiber yarns mix and knit can be that in polyetheretherketonefiber fiber yarn and aramid fibre yarn, glass fiber yarn, the cotton fiber yarn any one mixes to knit and form, and the content of polyetheretherketonefiber fiber yarn is 30%-70%.Polyetheretherketonefiber fiber yarn, aramid fibre yarn, glass fiber yarn, cotton fiber yarn all belong to existing material.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Embodiment
The utility model is described in further detail below in conjunction with embodiment's (polyether-ether-ketone enhancing composite bearing) and accompanying drawing thereof.
As shown in Figure 1, the polyether-ether-ketone of present embodiment enhancing composite bearing comprises nonmetal layer 3, metal outer 1 and adhesives layer 2.Nonmetal layer 3 adopts plain weave or satin weave mode to mix to knit by polyetheretherketonefiber fiber yarn and aramid fibre yarn (or glass fiber yarn, cotton fiber yarn) and forms, and the content of polyetheretherketonefiber fiber yarn is 30%-70%.Metal outer 1 is made by corrosion resistant plate (or copper coin) material.Adhesives layer 2 adopts common commercially available AB glue or epoxy resin, can add curing agent when using epoxy resin, to accelerate the solidification process of epoxy resin.Nonmetal layer 3 and metal outer 1 is compound by adhesives layer 2 to be one.
The advantage of comprehensive metal of present embodiment and nonmetallic bearing has following advantage:
1, bearing capacity is big, and good rigidly has higher intensity and hardness, peel off Du Keda 50 newton, and friction factor is little, does not damage friction pair.
2, have excellent self lubricity, wear resistance, can hold axle, do not need to add oiling agent as oil-free lubrication.If oil lubrication is arranged, performance can be doubled and redoubled, than superior many of metal.
3, cheap, simple in structure, shaping operation is easy to manufacture, can make the sliding bearing of different shape as required.
4, in some specific occasions, not only complete substituted metal sliding bearing, and also bigger than traditional metal sliding bearing effect.
5, have good anti fouling performance and anticorrosive property.Polyether-ether-ketone strengthens composite shaft, and to bear the influence of dust, contaminating impurity very little.It has mosaicism preferably, can " eat the material of dust, metal particle and so on ", and makes them be embedded into the interface bottom of polyetheretherketonefiber fiber, glass fibre, aramid fibre under the effect of pressure, reduces the wearing and tearing to friction pair.
Claims (6)
1. a composite bearing is characterized in that, it comprises nonmetal layer and the metal outer that is connected.
2. composite bearing as claimed in claim 1 is characterized in that nonmetal layer is mutually bonding with metal outer.
3. composite bearing as claimed in claim 2 is characterized in that, binder is AB glue or epoxy resin.
