Abstract
The invention provides a shield pump bearing. The shield pump bearing comprises an inner ring, an outer ring, a rolling body and a maintaining frame, wherein the rolling body of the bearing is manufactured by using graphite as a main material and adding a small amount of a compound material of silicon carbide and carbon fiber; and the inner ring, the outer ring and the maintaining frame are made of carbon fiber. The shield pump bearing has the advantages that: the inner ring and the outer ring of the bearing are made of carbon fiber materials with high hardness, the rolling body is still mainly made by using graphite as main materials and adding silicon carbide and carbon fiber for strengthening, so that the lubricating property of the graphite bearing is retained, the friction between the inner ring and the outer ring is reduced, and the service life of the berating is prolonged.
Description
Technical field
The present invention relates to a kind of bearing, especially a kind of shield pump bearing.
Background technique
Bearing is the fixed member in the machinery.When other parts produce relative movement each other on axle, be used for retainer shaft the central position and control the parts of this motion, just be referred to as bearing.
Study carefully it and be used for saying be to support, promptly literal interpretation is used for holding axle, but this is the part of its effect, supports its essence and can bear radial load exactly.Also can be understood as it and be used for fixing axle.Be exactly that stationary axle makes it can only realize rotating, and control its moving axially and radially.It is exactly can not work that motor does not have the consequence of bearing at all.Because axle may be to the motion of any direction, and require axle to rotate during machine operation.Can not realize the effect of transmission theoretically, moreover, bearing also can influence transmission, must realize good lubricating in order to reduce this influence on the bearing of high speed shaft, the bearing that has itself has had lubricated, is called prelubricated bearing, and most bearing must have lubricant oil, be responsible for when running up, because friction not only can increase energy consumption, more fearful is to be easy to damage bearing.The saying that sliding friction is changed into rolling friction is unilateral, because kind of a thing that is sliding bearing is arranged.Under certain loading, revolution that bearing is experienced before spot corrosion occurring or hour number are called bearing life.Since accuracy of manufacturing, the difference of material uniformity coefficient, even same material, the same a collection of bearing of same size uses under same operating conditions, its life-span length is also inequality.For determining the standard of bearing life, bearing life and reliability are connected.
But bearing is had relatively high expectations to its precision and quiet performance as a kind of accurate industrial devices, and the explanation bearing has had wearing and tearing largely when generally appearing at big noise, just is not suitable for continuing using for the bigger occasion of required precision again.
Summary of the invention
At the problems referred to above, the invention provides a kind of shield pump bearing.
A kind of shield pump bearing, comprise inner ring, outer ring, rolling element, retainer, the rolling element that it is characterized in that bearing adopts graphite as main raw material, wherein adds the composite material of small amount of carbonized silicon and carbon fiber, and its Internal and external cycle and retainer adopt carbon fiber to make.
Remarkable result of the present invention is that common shield pump bearing is improved, adopt the bigger carbon fibre material of hardness to make the Internal and external cycle of bearing, and rolling element still mainly adopts graphite is main raw material, added silicon carbide and carbon fiber is strengthened, not only keep the lubricity of graphite bearing but also can reduce frictional force between the Internal and external cycle, also prolonged the working life of bearing.
Embodiment
Below the present invention will be further described: the rolling element of bearing adopts graphite as main raw material, the composite material that wherein adds small amount of carbonized silicon and carbon fiber, its Internal and external cycle and retainer adopt carbon fiber to make, have excellent contact between graphite and the carbon fiber, also can not impact rotating speed.
Apply the present invention in the mechanical system, common shield pump bearing is improved, adopt the bigger carbon fibre material of hardness to make the Internal and external cycle of bearing, and rolling element still mainly adopts graphite is main raw material, added silicon carbide and carbon fiber is strengthened, not only keep the lubricity of graphite bearing but also can reduce frictional force between the Internal and external cycle, also prolonged the working life of bearing.
