Abstract
Disclosed is a low-cost and useful wear-resistant rotating joint. The wear-resistant rotating joint comprises a housing, the right portion of the housing is connected with a hollow shaft in a sleeve mode, the hollow shaft is connected with the housing through a bearing, a second O-shaped ring and a third O-shaped ring, the upper portion of the housing is provided with an oil nozzle, and the lower portion of the housing is provided with an oil discharging bolt and nut. The wear-resistant rotating joint is characterized in that a graphite sealing compensation ring is arranged at the right of the hollow shaft, the end surface of the graphite sealing compensation ring corresponds to the left end surface of the bearing, and the graphite sealing compensation ring is connected with the housing through a first O-shaped ring.
Description
Technical field
The present invention relates to a kind of SEALING FITTING, relate in particular to a kind of wear-resisting type swivel joint.
Background technique
Swivel joint of the prior art claims H type swivel joint (as shown in Figure 1) in the swivel joint industry
Mainly comprise hollow shaft, bearing, housing, graphite grazing sealing compensation ring, auxiliary seal ring, spring is formed.This kind swivel joint, simple in structure, rotation torque is little, the rotary seals that are used for various rotations or rotation motion component cooling water (or gas) more.Its sealing pair, routine has several: 1. stainless steel is to graphite; 2. silicon carbide is to silicon carbide; 3. cemented carbide is to graphite; 4. silicon carbide is to tin bronze etc.Cost is minimum, the use amount maximum be exactly first kind, stainless steel is to graphite.Because general Austenitic Stainless Steel material heat treatment process, bad realization can only improve its performance with solution treatment.This kind structure great majority do not take any processing to improve its performance to the stainless steel sealing surface in the industry at present.Cause the hollow shaft end face of the hard ring of conduct in use, groove appears in wearing and tearing too early.Cause leakage, as leak untimely processing, not only cause the waste of water resources, and the bearing length time contact with water, may cause bearing corrosion locking, pull apart the metallic hose of connection.
The swivel joint of all the other 3 kinds of sealing pair structures needs to inlay various materials at the hollow shaft end face; Change the material of compensated loop.All there is raising in various degree in cost.
Summary of the invention
The purpose of this invention is to provide the wear-resisting type swivel joint that a kind of cost is low, using effect is good.
For achieving the above object, the technical solution used in the present invention is: a kind of wear-resisting type swivel joint, comprise housing, the right part of housing is socketed with hollow shaft, be connected by bearing, the 2nd O shape circle and the 3rd O shape circle between hollow shaft and the housing, the housing upper design has oil nozzle, the lower housing portion design has the oil discharge screw nut, it is characterized in that: the left design of hollow shaft has the graphite grazing compensated loop, the end face of graphite grazing compensated loop is corresponding with the left side of bearing, is connected by O shape circle between graphite grazing compensated loop and the housing.
In this structure, design has spring mounting hole and spline pin-and-hole on the described graphite grazing compensated loop, and the split spring that passes on left of graphite grazing compensated loop is connected with housing with the spline pin, and split spring and spline pin lay respectively in spring mounting hole and the spline pin-and-hole.
In this structure, design has half point ring combination cover between the described bearing.
In this structure, the porose circlip of using of design between the right side wall of described bearing and housing.
Advantageous effect of the present invention is: because this structure of the present invention, the sealing pair of the stainless steel of swivel joint and graphite is changed to the sealing pair of bearing face (Bearing Steel) and graphite, so use the present invention wear-resisting, leak-down rate obviously reduces, alleviate 20-30% according to the statistics bearing face degree of wear than stainless steel end face, also have 20% raising working life, improved the abrasion resistance of the hard ring of swivel joint, the working life of having improved swivel joint.

Embodiment
The invention will be further described below in conjunction with the drawings and specific embodiments:
The present invention is shown in Fig. 2,3,4, a kind of wear-resisting type swivel joint, comprise housing 1, the right part of housing 1 is socketed with hollow shaft 9, be connected by bearing 6, the 2nd O shape circle 4 and the 3rd O shape circle 7 between hollow shaft 9 and the housing 1, housing 1 upper design has oil nozzle 5, the design of housing 1 bottom has oil discharge screw nut 11, it is characterized in that: the left design of hollow shaft 9 has the graphite grazing compensated loop, the end face of graphite grazing compensated loop is corresponding with the left side of bearing 6, is connected by O shape circle 2 between graphite grazing compensated loop and the housing 1.In the present embodiment, design has spring mounting hole 12 and spline pin-and-hole 13 on the described graphite grazing compensated loop, the split spring 3 that passes on left of graphite grazing compensated loop is connected with housing 1 with the spline pin, and split spring 3 and spline pin lay respectively in spring mounting hole 12 and the spline pin-and-hole 13.In the present embodiment, design has half point ring combination cover 10 between the described bearing 6.In the present embodiment, design is porose with circlip 8 between the right side wall of described bearing 6 and housing 1.
The bearing left side that is installed in the left side is ground to the mechanical seal technological requirement, it is cooperated with the graphite grazing compensated loop, carry out motive sealing.And at the close left side of brearing bore place's design spline point, prevent the rotation of bearing inner race and hollow shaft, and the hollow shaft left side mills out two U-shaped grooves, and the spline point is buckled in the U-groove bevel, and left side brearing bore and hollow shaft place arrange seal ring, prevent that medium from leaking outside;
The Monolithic spring change in design that will be in the medium is the split spring, and quantity is decided by the specification of swivel joint, is placed under the boss of graphite-seal ring compensated loop, the graphite grazing compensated loop is designed boss, spring is not in medium, and split type spring, and is more even to the pressure of sealing surface.Also avoided spring at the medium influence rate-of flow, at graphite grazing compensated loop boss, design prevents the U-shaped mouth, utilizes elastic cylindrical pin to prevent its rotation.
Intrinsic circlip for shaft is changed to half point ring combination cover, be placed in the middle of two bearings, also can play the effect of an oil flinger ring.
