Abstract
The utility model is a single-tube type rotating joint for cooling roller. The characters thereof are that: a casing(1) adopts integral structure and a bearing(6) is arranged between a rotating shaft(2) and the casing(1); sealing parts(7) contains a mechanical seal device(7') which consists of a moving ring(7a'), a static ring(7b'), a static ring seat(7c') and compression spring(7d'); the moving ring(7a') is inlayed at the left end of the rotating shaft(2); the static ring(7b'), static ring seat(7c') and compression spring(7d') are successively arranged between the moving ring(7a') and the left end of the inner cavity of the casing(1). Compared with the present technology, the utility model has the following outstanding advantages: 1) compared to the simple static seal structure, adopting the seal style having mechanical seal device has the following merits: the seal is more reliable, the leaking quantity is small and the service life is long. 2) adopting rolling shaft to replace graphite sliding bearing can improve rotating speed and can match and use with roller of different rotating speed requirements, which enlarges the application range.
Description
Technical field
The utility model relates to a kind of mechanically-sealing apparatus, particularly a kind ofly cools off the single hose swivel joint that roll is used.
Background technology
The roll of steel rolling equipment gyrates in rolling process, and works under hot conditions, must the water flowing of breaker roll inner chamber cool, so each roll all will dispose the swivel joint that the cooling roll is used for this reason.Fig. 1 is a kind of existing single hose swivel joint, be installed in the face end of roll respectively, this swivel joint is by housing 1a, housing 1b, rotating shaft 2, ring flange 3, subdivision ring 4, connecting ring 5, bearing 6, seal member 7 constitutes, be screwed connection between housing 1a and the housing 1b, have into (going out) mouth of a river on the housing 1a, connecting ring 5 matches with endoporus on the roll end, graphite sliding bearing 6 is arranged between housing 1b and the rotating shaft 2, housing 1a and housing 1b maintain static, rotating shaft 2 is by ring flange 3, subdivision ring 4, be connected as a single entity with screw and roll, cooling water enters the inner chamber of roll through rotating shaft 2 inside, discharge through roll other end single hose swivel joint after the cooling again, leaks in order to prevent cooling water, a plurality of seals 7 are set, and these seals adopt O RunddichtringO and unreinforced seal circle.The defective one of above-mentioned swivel joint is that sealing effectiveness is relatively poor, the 2nd, and adopt sliding bearing can not adapt to high speed rotary motion, limited the scope of application of swivel joint.
Summary of the invention
The purpose of this utility model provides a kind of single hose swivel joint that roll is used that cools off, and uses the problem that this single hose swivel joint can overcome the poor sealing performance of prior art effectively, and can with the at a high speed supporting use of roll of rotation
A kind ofly cool off the single hose swivel joint that roll is used, comprise housing 1, rotating shaft 2, ring flange 3, subdivision ring 4, connecting ring 5, bearing 6, seal member 7 is characterized in that: housing 1 adopts monolithic construction, and bearing 6 is arranged between rotating shaft 2 and the housing 1; Seal member 7 contain a mechanically-sealing apparatus 7 ', this mechanically-sealing apparatus 7 ' form by rotating ring 7a ', stationary ring 7b ', stationary seat 7c ', compression spring 7d ', wherein rotating ring 7a ' is embedded in the end of rotating shaft 2, and stationary ring 7b ', stationary seat 7c ', compression spring 7d ' are arranged between rotating ring 7a ' and the housing 1 inner chamber left part successively; Rotating ring 7a ' employing aluminium oxide ceramics ring, the carbon graphite ring that stationary ring 7b ' employing was soaked in phenolic aldehyde, bearing 6 adopts rolling bearing.The single hose swivel joint that this cooling roll is used rotating ring 7a ' and stationary ring 7b ' composition sealing surface, compression spring 7d ' is used to compensate the gap between rotating ring and the stationary ring, guarantee closely contact all the time between the dynamic and static ring, to improve the reliability and the service life of sealing, replace graphite sliding bearing with rolling bearing, can adapt to the various speed demand of roll.Cooling water glide path in single hose swivel joint and roll is same as the prior art.
With prior art relatively, the utlity model has following advantage: 1) adopt the sealing means that contains mechanically-sealing apparatus to compare than the simple static seal structure that adopts, sealing is reliable more, little, the long service life of leakage rate; 2) adopt rolling bearing to replace graphite sliding bearing, can improve rotating speed, the use that can match with the roll that different rotating speeds requires has enlarged the scope of application.
Description of drawings
The structural representation of the single hose swivel joint that Fig. 1 uses for existing cooling roll.
The structural representation of the single hose swivel joint that Fig. 2 uses for the design's cooling roll.
The specific embodiment
A kind ofly cool off the single hose swivel joint that roll is used, its structure as shown in Figure 2, housing 1 adopts monolithic construction, bearing 6 adopts rolling bearings, is arranged between rotating shaft 2 and the housing 1; Mechanically-sealing apparatus 7 ' rotating ring 7a ' employing through Φ 32 * Φ 22 * 6mm aluminium oxide ceramics ring of end face polishing, be embedded in rotating shaft 2 left parts, stationary ring 7b ' employing end face polishing soak phenolic aldehyde carbon graphite ring, be of a size of Φ 33 * Φ 22 * 5mm, stationary seat 7c ' employing bronze is made, the material of compression spring 7d ' is 3Cr13, its external diameter, internal diameter, line directly is respectively 35mm, 29mm, 2.5mm, remaining seal adopts the fluororubber O-type sealing ring, stationary ring 7b ', stationary seat 7c ', compression spring 7d ' is arranged between rotating ring 7a ' and the housing 1 inner chamber left part successively, ring flange 3 diameters are 140mm, fixedly connected with roll by 4 M12 * 40mm stainless steel screw, make rotating shaft 2 and roll do rotation synchronously.
Claims (3)
