Description
Technical field
The present invention relates to a kind of bearing, more particularly to a kind of circulating pump rubber shaft bearing.
Background technology
Recirculating cooling water system is the visual plant in nuclear power station conventional island, and its function is exactly to extract seawater to coagulate to steam turbine
Vapour device provides enough cooling waters, and the steam that work(is finished from turbine low pressure cylinder is cooled into condensate, participates in carbonated drink again and follows
Ring process, maintain the continuous operation of unit.
Used in nuclear power station water circulating pump is vertical pump, and the axial force of pump rotor is born by motor, and the radial load of rotor is by following
Ring pump guide bearing is born.Guide bearing is generally divided into two types, and one kind is rubber guide bearing, and another kind is babbit oil lubrication
Guide bearing.Rubber guide bearing has and can worked in seawater or water containing micro silt particle, and has absorbing, therefore wide
General use.
Circulating pump rubber guide bearing runs easy to wear exceeded, erosion resistant, antivibration, anti-impact for a long time in the seawater containing silt particle
The performance such as hit also to have much room for improvement.
The content of the invention
The present invention is directed to above-mentioned problems of the prior art, there is provided a kind of circulating pump rubber shaft bearing, solves existing
Rubber shaft bearing runs the problem of easy to wear exceeded for a long time in the seawater containing silt particle in technology.
Technical scheme is as follows：
Circulating pump rubber shaft bearing, bearing body are designed as splitted structure, and bearing body is combined into one by more valve strip bearings, often
Valve strip bearing is arranged on corresponding bearing body, and described every valve bearing uses metallic matrix liner rubber structure.
Described every valve bearing was provided with water groove vertically.
Described water groove excessively is shaped as arc asymmetry groove.
Described bearing body is combined into one by 6 valve strip bearings, and 6 described valve strip bearings are averagely set.
Described every valve bearing is installed on corresponding bearing body via fixing bolt and shop bolt.
Advantages of the present invention effect is as follows：
1st, bearing body is designed as splitted structure, improves the quick and convenience of bearing maintenance dismounting and installation.
2nd, water groove is integrally crossed per valve design bearing, it is ensured that bearing sufficient lubrication and cooling.
3rd, overall structure of the invention greatly improves erosion resistant, antivibration, the shock proof combination property of rubber shaft bearing, extends
The service life of rubber shaft bearing.

Embodiment
Embodiment
As illustrated, circulating pump rubber shaft bearing, bearing body is designed as splitted structure, and bearing body is combined by 6 valve strip bearings
Integrally, 6 valve strip bearings are averagely set, and corresponding bearing is arranged on via fixing bolt and shop bolt per valve strip bearing
On body, described every valve bearing uses metallic matrix liner rubber structure.Described every valve bearing was provided with water groove vertically.
That crosses water groove is shaped as arc asymmetry groove.
Matrix material of the present invention selects 316L, 316L to belong to austenitic stainless steel, equal to various inorganic acids, Organic Acid and Base, salt
There is preferable corrosion resistance, be that medium is the material that seawater is often selected；
Elastomeric material selects nitrile rubber, and nitrile rubber chemical-resistant stability is good, and tensile strength performance is high, has excellent physics
Property and processing characteristics.
Nitrile rubber physical property requirements：Shao Er hardness：50±3；30% stretching strength（N/cm2)：25；Breaking strength（N/
cm2)：85；Pull apart elongation percentage（%）：450；Pull-off strength（N/cm2)：35.
Bearing of the present invention can also be divided into the diversified forms such as 4 valves or 8 valves, above in association with accompanying drawing embodiment to the present invention
It is described in detail, those skilled in the art can make many variations example to the present invention according to the above description.Thus,
Some details in embodiment should not form limitation of the invention, and the present invention makees the scope defined with appended claims
For protection scope of the present invention.
