Abstract
The utility model discloses a balance compensation type rotating joint which comprises a shell body (1), an O-shaped ring (2), a combined spring (3), a static disc (4), a first ceramic ring (5), a second ceramic ring (6), a shaft check ring (7), a bearing (8), a spacer bush (9), a hole check ring (10) and a hollow shaft (11). The balance compensation type rotating joint is characterized in that the combined spring (3) is positioned on the bottom portion of the shell body (1), and the O-shaped ring (2) is arranged between the outer ring of the static disc (4) and the inner diameter of the shell body (1). The static disc (4) is contacted with the combined spring (3), the first ceramic ring (5) and the second ceramic ring (6) are inlaid in the end face of the hollow shaft (11) and are in rubbing seal with the end face of the static disc (4), the bearing (8) is arranged between the inner wall of the shell body (1) and the outer diameter of the hollow shaft (11), and the shaft check ring (7) and the hole check ring (10) are used for limiting and connecting the mentioned components into a whole. The balance compensation type rotating joint is evenly balanced in pressure and reliable in sealing.
Description
Technical field
The utility model belongs to mechanical device, particularly a kind of balance compensating swivel joint.
Background technique
At iron and steel, plastics, the pharmaceutical machine industry often can be met the problem that the media such as conveying water of cooling roll under rotation status cools off, and basically all adopts the plain edition whirligig to be solved.What often see at present is in cooling equipment, uses single spring to carry out pressure compensation, because the inhomogeneous build-up of pressure compensating for tilt that spring end face polishes, sealing effect is bad.Summary of the invention
For above-mentioned the deficiencies in the prior art, the utility model provides a kind of balance compensating swivel joint, and this swivel joint pressure uniform balance seals more reliable.
The technical solution of the utility model is: a kind of balance compensating swivel joint comprises housing 1, O type circle 2, cluster spring 3, quiet dish 4, the first ceramic rings 5, the second ceramic ring 6, shaft block ring 7, bearing 8, spacer 9, hole back-up ring 10, hollow shaft 11 is characterized in that: described cluster spring 3 is positioned at housing 1 bottom, and O type circle 2 is located between quiet dish 4 outer rings and housing 1 internal diameter.Quiet dish 4 contacts with cluster spring 3, the first ceramic ring 5, the second ceramic ring 6 are embedded in hollow shaft 11 end faces and the sealing of quiet dish 4 end-face frictions, bearing 8 is arranged between housing 1 inwall and hollow shaft 11 external diameters, and shaft block ring 7 and hole connect into integral body with back-up ring 10 is spacing with above-mentioned parts.
Further, described cluster spring 3 is formed by 3 groups of spring assemblies.
The utility model beneficial effect is: can drive hollow shaft and be rotated when cooling roll rotates.Have bearing to carry out stable support during the hollow shaft rotation, the ceramic ring that the ceramic ring that the hollow shaft end face is inlayed and quiet dish end face are inlayed plays under the ring compression friction sealed in combination.Medium is entered by housing bore, is transported to by hollow shaft in the cooling roll of rotation, has finished medium by quiet course of conveying to moving, and has finished the purpose to cooling roll safe transport medium.Owing to adopt cluster spring, so that the pressure uniform balance seals more reliable.
