Abstract
The invention relates to an H-type rotary joint which comprises a joint body, a space ring, a hollow shaft, an inner water pipe, an internal circlip, a bearing, an external circlip, a spring compensating component and a sealing component, wherein the inner water pipe is arranged in the joint body, and the spring compensating component and the sealing component are connected mutually and are arranged in the rear of the hollow shaft. The H-type rotary joint is small in size, lightweight, more reliable in sealability, less in friction force and longer in service life, and working stability and the service lives of rollers of a continuous casting machine are further guaranteed.
Description
Technical field
The present invention relates to the roller cooling unit on a kind of casting machine, relate in particular to a kind of H type swivel joint.
Background technique
The temperature of control Continuous Casting Machine Rollers is the key that prolongs normal running and reduce maintenance cost.Controlling energetically liquid stream and temperature produces defective and guarantees that product stability is extremely important for avoiding in the casting process.Swivel joint allows cooling water to flow into and flows out Continuous Casting Machine Rollers, so that the temperature of control roll and bearing prevents bearing failure.Existing swivel joint volume is large, Heavy Weight, and sealing is relatively poor, and leakage accident occurs easily, and working life is shorter.
Summary of the invention
The present invention is in order to overcome the above problems the H type swivel joint that a kind of simple in structure, easy to use, good airproof performance, long service life are provided.
Technological scheme of the present invention is: comprise adapter body, spacer ring, hollow shaft, inner conduit, circlip for hole, bearing, circlip for shaft, described inner conduit is arranged in the adapter body, described joint also comprises interconnective spring-compensating assembly and black box, and described spring-compensating assembly and black box are arranged on the rear portion of hollow shaft.
Described spring compensator comprises spring, pad and O RunddichtringO, and described spring one end is arranged in the endoporus of adapter body, and the other end connects pad and O RunddichtringO successively; Described black box comprises silicon carbide Sealing and straight pin, and straight pin is arranged in the hole of silicon carbide periphery.
Also be provided with lubricating cup and peep hole on the described adapter body, the oil outlet of described lubricating cup communicates with bearing.
Volume of the present invention is little, and is lightweight, employing be mechanical seal, mechanical seal not only forms and tiny leakage, and produces quite little frictional force at a high speed down again.What our Sealing was selected is silicon carbide, have good especially frictional behavior and high thermal conductivity, and our Sealing machines at CNC lathe and special grinder bed, smooth surface is as minute surface, make sealing more reliable, frictional force is less.Adopt spring-compensating, spring auto-compensation when sealing part abrasion contacts the end face of Sealing all the time, does not leak, and has prolonged the working life of swivel joint.Can guarantee the maintainability of swivel joint bearing regularly to the bearing oiling by lubricating cup, prolong the working life of bearing.Can observe swivel joint and whether leak regularly by the peep hole on the main body of swivel joint, observe the abrasion condition of inner body, in order to timely swivel joint is maintained and changed.Can prevent machinery to shut down or mechanical failure, reach preventive effect and reduce the loss.Thereby working stability and the working life of Continuous Casting Machine Rollers have further been guaranteed.
