Description

Hydraulic rotary joint

Technical Field

The utility model relates to the technical field of hydraulic rotary heads, in particular to a hydraulic rotary joint.

Background

The hydraulic rotary joint is a rotary joint specially used for low-speed high-pressure various media and multi-channel equipment, and is used for equipment such as a hydraulic workstation, a large-scale rotary table, a hydraulic machine, a multi-channel high-pressure controller and the like.

The rotary joint is a connecting sealing device for inputting high-pressure fluid medium into rotary equipment from a static pipeline, and when the high-pressure fluid actuating mechanism equipment has angle swinging and rotation requirements in the action process, the rotary joint is generally used for butting the pipeline to meet the requirement of medium transmission, especially in the fields of steel, mines and the like. In the working condition of bearing high pressure and high impact load, the traditional rotary joint has the advantages that the impact force of high-pressure oil liquid to the inside of the rotary joint enables the bearing of the rotary mechanism to bear alternating impact locally, abrasion is increased, coaxiality stability is deteriorated, and service life is influenced. The rotary joint of traditional structure adopts single row ball bearing structure's axiality stability is poor, lead to rotary joint seal extrusion deformation, can appear high pressure oil liquid leakage when bearing high impact, influence production cost and safety in production, for example authorize bulletin as CN205877513U, have shock resistance hydraulic rotary joint, this rotary joint structure includes the rotator, the shell, O type circle, back lid and jump ring, a serial communication port, still including setting up the double ball bearing on the rotator, compress tightly by the shell, a row of ball bearing sets up between O type circle and the oil inlet of rotator front end, another row ball bearing sets up on the axle of rotator rear end, the rotator inside is equipped with oil inlet and oil-out, the oil-out with the rotator is coaxial, the oil inlet with the oil-out communicates perpendicularly, the oil inlet both ends of rotator radial direction are equipped with sealing device, the shortcoming that traditional rotary joint single row rotary bearing was worn out in bearing local when high impact load has been solved, the oil feed mode is from traditional rotator tip oil feed to rotator middle part oil feed, reduce rotator radial force, improve tip seal and wear oil, and adopt the duplex bearing to make high pressure oil to offset the internal pressure of two directions, and the balanced joint life of bearing is realized, and the self-balancing wear is leaked. When the rotary joint works, the design of the high-pressure self-balancing structure of the double-row bearing in the rotary joint ensures that the whole structure of the rotary joint is more stable and reliable, the front end bearing and the rear end bearing of the rotary body can still be kept coaxial under the conditions of radial force and vibration of the assembled fluid actuating mechanism, and the occurrence of severe extrusion failure condition of sealing under external force is reduced.

The hydraulic rotary joint has no automatic cleaning function, is complex and troublesome to clean used equipment, does not clean for a long time, aggravates the work load of the hydraulic rotary joint, reduces the service life of the machine, and is unfavorable for long-term use of the machine.
