Abstract
The utility model provides a rubber bearing. The rubber bearing comprises a metal shell, a rubber layer and an anti-corrosion wear-resistant coating; the rubber layer is coated on the whole inner surface of the metal shell; the inner surface of the rubber layer is provided with the anti-corrosion wear-resistant coating. The rubber bearing has the characteristics of simple and reasonable structure, novel selected materials, good wear-resistant property and high anti-corrosion property, and can be used for prolonging the service life of the rubber bearing.
Description
Technical field
The utility model relates to a kind of bearing, is specifically related to the slurry generator rubber bush bearing in a kind of oil-well drilling equipment.
Background technique
Bearing is a kind of important base components that is widely used in all kinds of machineries, is used for bearing load and makes rotation, swing or linear reciprocating motion.Rubber bush bearing is to be used for the vitals of slurry generator in the serial pulse generator of wireless drilling gradient of petroleum drilling apparatus 650.Be applied at present the rubber bush bearing in this field, be subjected to the limitation of the temperature tolerance of rubber material own, wear resistance and chemical mediator-resitant property, use in the different down-hole slurry media of different regions and have different damage types, such as eccentric wear, seize stuck phenomenon, and easy to wear, perishable, the life-span is short, prior art is difficult to deal with problems with relatively simple unified rubber process and formula Design, increases the service life.
Summary of the invention
The purpose of this utility model is to overcome the above-mentioned problems in the prior art, and a kind of rubber bush bearing is provided, and that this rubber bush bearing has is simple and reasonable, wear-resisting property good, the characteristics that corrosion resistance is strong, the working life that can effectively improve rubber bush bearing.
The utility model provides a kind of rubber bush bearing, comprises metal shell, rubber layer and corrosion protection wear resistant coating, and described rubber layer is coated on the whole internal surface of described metal shell; Described rubber layer internal surface is provided with described corrosion protection wear resistant coating.
The material of described metal shell is bronze, as beryllium bronze, aluminum bronze etc.
The hardness of described rubber layer is not less than the hardness of the seal ring that is mated, and the hardness of described rubber layer is shore hardness 70～90 degree.
Described rubber layer is nitrile butadiene rubber, hydrogenated nitrile-butadiene rubber, butyl rubber, neoprene, carboxylic butyronitrile, chlorohydrin rubber, polyacrylate or fluorine rubber.
Described corrosion protection wear resistant coating is PTFE, FEP or PFA.
Described corrosion protection wear resistant coating thickness is 0.01mm-0.2mm.
Preferably, described corrosion protection wear resistant coating thickness is 0.2mm.
The utility model can adopt following any one mode in use:
(1) rubber bush bearing and metal shaft are used in conjunction with.(2) interior metal axle and rubber bush bearing relative rotary motion in using process.
The utility model is simple and reasonable, selection is novel, wear-resisting property is good, and corrosion resistance is strong, simultaneously, can effectively improve the working life of rubber bush bearing.
Description of drawings
Fig. 1 is generalized section of the present utility model;
Fig. 2 is structural representation of the present utility model;
Embodiment
Below in conjunction with accompanying drawing, the utility model is done further and explained.
As shown in Figure 1, the utility model provides a kind of rubber bush bearing, comprises metal shell 1, rubber layer 2 and corrosion protection wear resistant coating 3, and rubber layer 2 is coated on the internal surface of whole metal shell 1; Rubber layer 2 internal surfaces are provided with corrosion protection wear resistant coating 3.
Preferably, the material of metal shell 1 is bronze, preferably beryllium bronze or aluminum bronze, and bronze has the characteristics more wear-resisting than brass, that intensity is higher, can better improve the working life of rubber bush bearing.
The hardness of rubber layer 2 is not less than the hardness of the seal ring that is mated, and the hardness of rubber layer 2 is shore hardness 70～90 degree.
As shown in Figure 2, corrosion protection wear resistant coating 3 adopts fluorocarbon surface modified coating material and all kinds of fluorine coating, has excellent resistant to chemical media corrosivity, by rubber layer 2 all surfaces are carried out modification or adhere to rubber layer 2 all surfaces.Coating has excellent high temperature resistant and resistant to chemical media corrosivity, completely cuts off or weakens different mud mediums to the corrosion of rubber part.Corrosion protection wear resistant coating 3 is thick in 0.01～0.2mm scope.Degree abominable according to environment used, the cladding material kind is different with coating process thickness.
Preferably, corrosion protection wear resistant coating 3 is PTFE, FEP or PFA.
Preferably, corrosion protection wear resistant coating 3 thickness are 0.01-0.2mm.
Preferably, corrosion protection wear resistant coating 3 thickness are 0.2mm.Under this thickness, rubber bush bearing is best with coordinating of metal shaft, has best corrosion resistance and wear resistance, can effectively improve the life-span of rubber bush bearing.
In use, can adopt following any one mode: (1) rubber bush bearing and metal shaft are used in conjunction with.(2) interior metal axle and rubber bush bearing relative rotary motion in using process.
The above is only preferred embodiment of the present utility model, is not be used to limiting protection domain of the present utility model.All within spirit of the present utility model and principle, any modification of doing, be equal to and replace and improvement etc., within all should being included in protection domain of the present utility model.
