Description

A kind of built-in two-way swivel joint
Technical field
The utility model relates to a kind of joint, particularly relates to a kind of built-in two-way swivel joint.
Background technique
The roll of steel rolling equipment needs to gyrate in rolling process, and is to carry out work under high temperature condition; For this reason must be to the inner chamber water flowing of each rotary roller in order to cool, so the swivel joint that a cooling roll is used all will be installed in each roll end.Existing two-way swivel joint, complex structure, volume are bigger.Be subjected to the qualification of its structure, the two-way swivel joint of this kind can only be placed on the outside of roller assembly when reality is used; The defective that is caused is as follows: 1, occupied than large space, brought inconvenience therefore for the installation of all the other annexes; 2, neat and artistic inadequately with the monnolithic case of roller assembly combination back formation.
The model utility content
At the deficiencies in the prior art part, the utility model provides a kind of built-in two-way swivel joint that can be placed in roller assembly inside.
The utility model is for reaching above purpose, be to realize: a kind of built-in two-way swivel joint is provided by such technological scheme, comprise water service pipe, also comprise housing I and housing II, the rotating shaft of hollow and housing I are fixedly linked, and housing II links to each other by rolling bearing with rotating shaft, are provided with water service pipe in rotating shaft, form the gap between the inwall of water service pipe and rotating shaft, on housing II, be respectively equipped with water intake and water outlet; The intracavity inter-connection of water outlet and water service pipe, water intake is connected with the gap; Between water intake and gap, face seal components is set.
A kind of improvement as built-in two-way swivel joint of the present utility model: face seal components is made up of rotating ring, stationary ring, the stationary seat that is provided with flow channel, O-ring seals and pressure spring; Stationary seat links to each other with housing II, and the two ends of flow channel communicate with water intake and gap respectively; The end face of rotating ring and rotating shaft is fixedly linked, and the end face of stationary ring and stationary seat is fixedly linked, and rotating ring contacts with stationary ring; Be provided with O-ring seals between the internal surface of stationary seat and housing II, an end of pressure spring is supporting housing II, the other end is supporting stationary seat.
During the actual use of built-in two-way swivel joint of the present utility model, can basically whole swivel joint be placed roller assembly inside, make whole swivel joint not expose substantially.Therefore compare with swivel joint, have following advantage: saved the space, helped the installation of all the other annexes as prior art; Make and the compactness more that combines structurally of roller assembly, therefore make monnolithic case more neat and artistic.
Description of drawings
Fig. 1 is the cross-sectional schematic of built-in two-way swivel joint of the present utility model.
Embodiment
With reference to above-mentioned accompanying drawing, embodiment of the present utility model is elaborated.Fig. 1 has provided a kind of built-in two-way swivel joint, comprises housing I2 and housing II4.Housing I2 is a circle ring column; Housing II4 is a cylindrical body, and its left end has dug counterbore, and its right-hand member is provided with positioning base, is provided with flange 41 (rely on this flange 41, housing II4 can link to each other with roller support when reality is used) on this positioning base.Rotating shaft 3 parts of hollow are positioned at the inside of housing I2, the counterbore that part is positioned at housing II4.Rotating shaft 3 is fixedlyed connected by fixing pin 1 with housing I2; Housing II4 is provided with rolling bearing 9, and rotating shaft 3 realizes flexibly connecting with housing II4 by rolling bearing 9.In rotating shaft 3, be provided with water service pipe 11, form gap 10 between the inwall of water service pipe 11 and rotating shaft 3; On housing II4, be respectively equipped with water intake 7 and water outlet 6; The intracavity inter-connection of water outlet 6 and water service pipe 11, water intake 7 is connected with gap 10.In order to keep sealing, to prevent that cooling water from leaking, and is provided with face seal components between water intake 7 and gap 10.
This face seal components is made up of rotating ring 54, stationary ring 55, stationary seat 51, O-ring seals 52 and pressure spring 53.Stationary seat 51 is cylinders that a left end has positioning boss 513, and the right-hand member of this cylinder is made chamfered and formed chamfer surface 511; The center of this stationary seat 51 is provided with flow channel 512.The column part of stationary seat 51 is positioned at water inlet 7, and and the inwall of water inlet 7 between keep certain little gap.Positioning boss 513 links to each other with housing II4 by pin 8.Between the chamfer surface 511 of stationary seat 51 and the inwall of water inlet 7 O-ring seals 52 is set, thereby guarantees water leakage phenomenon not to take place.Stationary ring 55 is embedded on the end face of positioning boss 513, and rotating ring 54 is embedded on the end face of rotating shaft 3; Pressure spring 53 1 ends that are positioned at water inlet 7 are supporting housing II4, the other end is supporting stationary seat 51; Thereby guarantee stationary ring 55 and rotating ring 54 closely contact mutually.Stationary ring 55 adopts bright finished technology to handle with the surface of contact of rotating ring 54, has guaranteed the sealing of this surface of contact.The material of stationary ring 55 and rotating ring 54 is different according to working environment (for example operating temperature, rotating speed or the like), can adopt engineering ceramics, silicon carbide, impregnated graphite and cemented carbide or the like.
During built-in two-way swivel joint real work of the present utility model, housing II4 links to each other with roller support by the flange on the positioning base 41, so housing II4 is maintained fixed motionlessly, and stationary ring 55, stationary seat 51 and water service pipe 11 all are maintained fixed motionless.Except the positioning base on this housing II4, the remaining part of swivel joint of the present utility model all is positioned at roller assembly.Its middle shell I2 is positioned at roll, and the outer surface of housing I2 and the inwall of roll form the interference fit of negative clearance; Therefore rely on frictional force between the two, roll just can drive housing I2 and rotating shaft 3 rotates together.Cooling water 7 flows into gaps 10 through flow channel 512, stationary ring 55 and rotating ring 54 successively from the water inlet, finally enters the roll inner chamber and implements to cool.Waste water after the heating flows into water service pipe 11 from the roll inner chamber, discharges from water outlet 6 at last.
At last, it is also to be noted that what more than enumerate only is a specific embodiment of the present utility model.Obviously, the utility model is not limited to above embodiment, and many distortion can also be arranged.All distortion that those of ordinary skill in the art can directly derive or associate from the disclosed content of the utility model all should be thought protection domain of the present utility model.
