Abstract
The utility model discloses a high-speed rotary joint which comprises a shell (1), a spring (2), a spring cushion (3), an auxiliary sealing ring (4), an antimony-impregnated graphite ring (5), a ceramic ring (6), a shaft check ring (7), a bearing (8), a hole check ring (9) and a hollow shaft (10). One end of the spring (2) is positioned at the bottom of the shell (1); the other end of the spring (2) is in contact with the spring cushion (3); the auxiliary sealing ring (4) is arranged between the inner wall of the shell (1) and the outer diameter of the antimony-impregnated graphite ring (5); the ceramic ring (6) is embedded on the end face of the hollow shaft (1) and is sealed with the antimony-impregnated graphite ring (5) in a friction manner; the bearing (8) is arranged between the inner wall of the shell (1) and the outer diameter of the hollow shaft (10); and the shaft check ring (7) and the hole check ring (9) are used for limiting to connect all parts into a whole. The high-speed rotary joint has the advantages and effects of simple structure, high-speed rotation, stability for supporting and the realization of the highest rotating speed of 2,000 revolutions per minute.
Description
Technical field
The utility model relates to a kind of swivel joint, particularly a kind of high-speed type swivel joint.
Background technique
At iron and steel, the rubber manufacturing machinery industry is met the problem that cooling roll cools off at the media such as transporting water under the rotation status through regular meeting, all adopts the plain edition whirligig to solve basically.What often see at present is for enhancing productivity, and the cooling roll rotating speed increases substantially, and this just makes that original common whirligig is easy to wear, and the life-span is short, change frequent, waste material resources, financial resources.
Summary of the invention
The utility model is to the deficiency of above-mentioned existing technology, provide a kind of simple in structure, rotation at a high speed, the high-speed type swivel joint of supporting & stablizing.
The technological scheme of the utility model is: the high-speed type swivel joint; Comprise: housing 1, spring 2, spring pad 3, auxiliary seal ring 4, soak antimony graphite annulus 5, ceramic ring 6, shaft block ring 7, bearing 8, hole with back-up ring 9, hollow shaft 10; It is characterized in that: said spring 2 one ends are positioned at housing 1 bottom; Spring 2 the other ends contact setting with spring pad 3, and auxiliary seal ring 4 is between housing 1 inwall and soak between antimony graphite annulus 5 external diameters, and ceramic ring 6 is embedded in hollow shaft 1 end face and to soak antimony graphite annulus 5 friction sealed; Bearing 8 is arranged between housing 1 inwall and hollow shaft 10 external diameters, and shaft block ring 7 and hole connect into integral body with back-up ring 9 is spacing with all parts.
The utility model has the advantages of: when cooling roll rotates, can drive hollow shaft and be rotated.The hollow shaft rotation time has bearing to carry out stable support, and the ceramic ring that the hollow shaft end face is inlayed is playing under the ring compression friction sealedly with soaking the antimony graphite annulus, and friction is extremely low, and bearing adopts NSK to be suitable for high speed rotating.Medium is got into by housing bore, be transported to through hollow shaft in the cooling roll of rotation, accomplished medium by quiet to moving course of conveying, accomplished purpose to cooling roll safe transport medium.2000 rev/mins of the utility model maximum speeds, maximum pressure is 1.8MP, is applicable to media such as air, water.
