Two relative rotation bodies be sealed, generally included labyrinth type, Weight type, fish scale chip, presser type sealing structure；This is several
Kind of sealing structure using when revolving part and fixing piece between because relative displacement that sealing generates all can caused by reveal, i.e., in sealing
All there is leakage problem, and amount of leakage is very big, cannot satisfy the use demand.
Invention content
It is an object of the invention to the rotary joint structure complexity for existing diameter 400mm or more cumbersome, diameter compared with
Two big relative rotation bodies are sealed the problems such as causing leakage, provide a kind of rotatory sealing of axial-radial automatic adjustment
Mechanism.
To achieve the above object, institute is the present invention using technical solution：A kind of rotation of axial-radial automatic adjustment
Sealing mechanism, including static housing and rotary barrel further include having ceramic cotton, transition ring flat-plate and support ring frame, the pottery
Porcelain cotton one end is fixed on by cotton pressing plate on static housing, and the ceramic cotton other end is fixed on transition rings by cotton pressing plate
Plate side, the transition ring flat-plate are circumferentially provided with multiple connecting springs, and transition ring flat-plate passes through multiple connecting springs and support ring
The inner ring of frame is connected, and herein multiple are three or three or more, and the rotary barrel is fixed by spring press roll component
In the transition ring flat-plate other side.
The KmTBCr12 cast iron layers of anticorrosive anti-wear are provided between the transition ring flat-plate and rotary barrel contact surface.
The spring press roll component includes screw rod, pressure roller shaft, pressure roller and leading screw axle sleeve, and the screw rod is welded on transition
On ring flat-plate, the idler wheel of the pressure roller is connected by the axis of pressure roller shaft with leading screw axle sleeve, and the leading screw axle sleeve is hollow ring set,
Leading screw axle sleeve is nested in screw rod close to transition ring flat-plate end, and the screw rod other end is provided with bolt, the leading screw axle sleeve and
Spring is provided between bolt.
Compared with prior art, the beneficial effects of the invention are as follows：
Ceramic cotton one end is fixed on by cotton pressing plate on static housing in the present invention, and the ceramic cotton other end passes through cotton
Cloth pressing plate is fixed on transition ring flat-plate side, and transition ring flat-plate is circumferentially provided with multiple connecting springs, and transition ring flat-plate passes through multiple connections
Spring is connected with the inner ring of support ring frame, and rotary barrel is fixed on the transition ring flat-plate other side by spring press roll component.Pass through
Transition ring flat-plate is hung up using the characteristic of connecting spring, rotary barrel and transition ring flat-plate is allowed to be fitted tightly over together；And it makes pottery
The flexibility of porcelain cotton itself solves fixing pieces and the rotary barrel relative displacements such as static housing, ceramic cotton, transition ring flat-plate
Caused by deform, therefore it is with good leakproofness and pressure-sensitive ability, solves two relative rotation bodies being relatively large in diameter not
The problem of being absolutely sealed can be reached.
