Abstract
The invention relates to the technical field of bearings, in particular to a high-intensity carbon fiber composite bearing. The high-intensity composite bearing consists of tapered rollers, a double-rollaway outer ring, outer spacing rings, single-rollaway outer rings, retainer frames, struts, double-rollaway inner rings and an inner spacing ring; the double-rollaway outer ring and the two single-rollaway outer rings are arranged in the middle of the bearing; the outer spacing ring is arranged between each single-rollaway outer ring and the double-rollaway outer ring; the bearing is provided with the two double-rollaway inner rings; the inner spacing ring is arranged between the double-rollaway inner rings; the tapered rollers are arranged between the double-rollaway inner rings and the single-rollaway outer rings and between the double-rollaway inner rings and the double-rollaway outer ring; a strut passes through the center of each tapered roller; and the retainer frames are arranged at the two ends of each strut.
Description
Technical field
The present invention relates to technical field of bearings, concrete relate to a kind of high-strength carbon fiber composite bearing.
Background technique
Four-row tapered roller bearing is one of main rolling bearing, and the radial and axial load-carrying ability of this class bearing is all bigger, can bear bigger bi-directional axial load.The retainer material of traditional four-row tapered roller bearing is nonmetallic material such as alloy material or nylon.Because intermetallic friction is bigger, must guarantee when using the metal retainer that generally retainer guiding surface and bearing inside provide enough lubricating.Nylon cages has smooth surface, and friction factor is little, but there is certain problem in aspects such as its wear resistance and hydrolytic resistance, and workability is poor than metal.Therefore, explore new retainer material to satisfy in the high tenacity operation such as mining military industry field requirement to bearing high-temperature corrosion resistance, characteristic such as wear-resistant.
Summary of the invention
Defective in view of prior art exists the objective of the invention is to provide a kind of high-strength carbon fiber composite bearing, improves the high-temperature corrosion resistance of bearing, characteristic such as wear-resistant, prolongs its working life.
High-strength carbon fiber composite bearing of the present invention is made up of tapered roller, outer ring with double raceway, outer ring spacer, single raceway outer ring, retainer, pillar, two raceway inner ring and cone spacer; It is characterized in that: have an outer ring with double raceway in the middle of this bearing; There is an outer ring spacer two single raceway outer rings between each single raceway outer ring and the outer ring with double raceway; This bearing has two two raceway inner rings, is provided with a cone spacer between two raceway inner rings; Between two raceway inner rings and single raceway outer ring, the outer ring with double raceway tapered roller is set, a pillar is passed at each tapered roller center, and the pillar two ends are retainer.
The retainer of high-strength carbon fiber composite bearing of the present invention adopts carbon fiber composite.Described carbon fiber composite is handled gained by graphite fiber, teflon, graphite and polyether-ether-ketone through expecting multiple working procedures such as processing, has higher wear-resisting and corrosion resistance, lower friction factor.The four-row tapered roller bearing that utilizes this carbon fibre material to make has long working life.The present invention can be widely used in the machinery of various high tenacity operations.
