Detailed description of the invention
As depicted in figs. 1 and 2, it is provided that a kind of integrated rotary, being specially radial tire forming machine swivel joint, swivel joint includes afterbody to be had the elbow 1 of radial air inlet mouth, has the threeway 2 of air inlet, outer tube 12, interior pipe 14 and shaft parts 17；One end of described threeway is positioned at described elbow, the other end of described threeway is connected by one end of the rotatable and described outer tube of bearing 10, described bearing is axially positioned by hole back-up ring 11, bearing 10 supports outer tube 12 by endoporus, axially positioned by the shaft block ring 9 on outer tube 12, flange 15 and outer tube 12 weld together, and are fixed in shaft parts 17 by screw 19；The other end of described outer tube is connected to described shaft parts, described outer tube sleeve is located at outside said inner tube, described outer tube is by gripper shoe 13 and the integrally welded formula structure of said inner tube, and one end of said inner tube extend out in elbow in outer tube and contacts with described threeway, the other end of said inner tube extend out in shaft parts in outer tube.
It is to be appreciated that described gripper shoe is along the circumferential direction distributed between outer tube and interior pipe.Preferably, described gripper shoe is six.Outer tube and interior pipe are set in together by six gripper shoes, reach the purpose of inner and outer pipes one, on the basis of the ventilatory effect ensured between outer tube and interior pipe, the weight of interior outer shaft can be made again to be supported all through bearing, it is ensured that interior pipe two ends sealing ring does not stress；And inner and outer pipes integral structure solves interior axle and supports problem, the outer end spring bearing of the desirable shaft parts that disappears, solve bearing removal difficulty and cause that problem not easily changed by sealing ring；And inner and outer pipes integral structure, the alternative of axle outlet side form in ensureing, bright finish axis hole can be adopted to add the fit system of sealing ring, ensure that gas directly and makes the conveying between appliance, may be used without interior pipe outer end processing sealing pipe screw thread to be connected with modular, pneumatically powered female thread quick connector, carried out the form of indirect gas transmission by PU pipe, this form can solve the problem that hollow axle cavity is divided into two-way gas to cause interior pipe long.Concrete, described six gripper shoes are divided into two groups, adopt at outer tube two ends and are attached in the mode that circumferencial direction is uniform, it is ensured that outer tube and the circulation effect of gas in interior pipe.
As one embodiment of the present of invention, front end and the described threeway of described outer tube are sealed by black box, and described black box includes spring 5, is installed on the spring pad 6 of spring right-hand member, is installed on the auxiliary seal ring 7 of spring pad right-hand member, is installed on the sealing ring 8 of auxiliary seal ring right-hand member.Preferably, the material of described sealing ring is impregnated graphite materials or the coefficient of friction of the minimizing of other associated materials and outer between centers, applies a force to sealing ring 8 by spring 5 is continual, it is ensured that the long term seal effect between sealing ring 8 and outer tube 12.
As one embodiment of the present of invention, described outer tube and described shaft parts are sealed by exterior seal ring 16
Sealed by sealing ring 18 as one embodiment of the present of invention, said inner tube and described shaft parts.Eliminating spring bearing of the prior art, two pieces sealing ring has reached sealing effectiveness, and solving bearing affects the problem that sealing ring is changed, it is ensured that in shaft parts 17, two-way gas is each flat.
As one embodiment of the present of invention, said inner tube and described threeway are sealed by inner seal ring 3, namely inlet end adopts two inner seal rings, strengthens the sealing effectiveness between threeway and interior pipe, it is ensured that swivel joint is long lasting for the sealing effectiveness in uninterrupted operation process.
It is additionally provided with sealing ring 4 as one embodiment of the present of invention, said inner tube and described threeway touching position.The internal pipe of sealing ring at air inlet place plays the effect that an auxiliary supports, and strengthens the support of interior pipe inlet end, and the use of sealing ring 4 can eliminate the situation of inner seal ring 3 discontinuity, has thoroughly stopped the inlet end inner seal ring problem by radial force.Further, described inner seal ring selects the coefficient of friction between impregnated graphite materials or the minimizing of other associated materials and interior pipe, solves the problem that between former interior pipe and threeway, frictional force is big.
The present invention can summarizing without prejudice to the spirit of the present invention or the concrete form of principal character with other.Therefore, no matter from which point, the embodiment above of the present invention all can only think that the description of the invention can not limit the present invention, claims indicate the scope of the present invention, and the scope of the present invention is not pointed out in above-mentioned explanation, therefore, any change in the implication suitable with claims of the present invention and scope, all it is considered as being included in the scope of claims of the present invention.
