Abstract
The utility model relates to a wear-resisting rotating joint with advantages of low cost and good use effect. The wear-resisting rotating joint comprises a shell, wherein a hollow shaft is sleeved at the right part of the shell and is connected with the shell through a bearing, a second O-shaped ring and a third O-shaped ring, an oil nozzle is arranged at the upper part of the shell, and an oil-discharging bolt nut is designed at the lower part of the shell. The wear-resisting rotating joint is characterized in that a graphite seal compensation ring is designed at the left side of the hollow shaft, wherein the end face of the graphite seal compensation ring corresponds to the left end face of the bearing, and the graphite seal compensation ring is connected with the shell through a first O-shaped ring.
Description
Technical field
The utility model relates to a kind of SEALING FITTING, relates 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, the graphite grazing sealing compensation ring, auxiliary seal ring, spring forms.This kind swivel joint, simple in structure, rotation torque is little, and is multiplex in the rotary seal to various rotations or rotation motion component cooling water (or gas).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 the first, 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 in use hollow shaft end face of the hard ring of conduct, 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 the bearing rust 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 utility model provides 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 adopted in the utility model 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, lower housing portion is designed with the oil discharge screw nut, it is characterized in that: the left of hollow shaft is designed with 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, be designed with spring mounting hole and spline pin-and-hole on the described graphite grazing compensated loop, 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, be designed with half point ring combination cover between the described bearing.
In this structure, be designed with circlip for hole between the right side wall of described bearing and housing.
The utility model has the advantages of and be: because this structure of the present utility model, 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 utility model 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 utility model is described in further detail below in conjunction with the drawings and specific embodiments:
The utility model 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, housing 1 bottom is designed with oil discharge screw nut 11, it is characterized in that: the left of hollow shaft 9 is designed with 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, be designed with 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, be designed with half point ring combination cover 10 between the described bearing 6.In the present embodiment, be designed with circlip for hole 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 Technology of Mechanical Seal 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 Separated 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.
