Description
Technical field
The utility model belongs to rotary joint technical field more particularly to a kind of hydraulic tubular rotary joint.
Background technique
Hydraulic rotary joint be it is a kind of dedicated for high pressure, multimedium, multi-pass pipeline equipment rotary joint, hydraulic swing switching
Head is internally provided with independent pipeline, can support the demand of different operating situation, has very strong practicability.
The high-speed joint of domestic production at present generally uses clearance seal, and seal clearance can be due to external interference
And change, cause abrasion to aggravate, and then leak, in the work of large-diameter high-speed rotary joint, this problem is more
Add protrusion.In order to guarantee overall mass, which often relies on import, and import parts are expensive, substantially increase and are produced into
This.
Utility model content
In order to solve problem above, the utility model provides a kind of hydraulic tubular rotary joint.
The utility model is realized in this way: a kind of hydraulic tubular rotary joint, including shell, described shell one end are provided with
Drive end bearing bracket, the other end are provided with rear end cap, are fixed protection to shell by drive end bearing bracket and rear end cap, and the one of the drive end bearing bracket
Side is connected with shaft joint, and the side of the rear end cap is connected with axle sleeve union elbow, and inner tube is provided in the shell, carries out
The circulation of medium, the both ends of said inner tube are respectively arranged with the first precision bearing and the second precision bearing, operate rotary joint
It is steady it is persistently reliable, firm flexibly, coefficient of friction it is small, first precision bearing is located at close to one end of drive end bearing bracket, described the
Two precision bearings are located at close to one end of rear end cap, and the junction of first precision bearing and shaft joint is provided with UN sealing
Circle reduces abrasion, and the junction of second precision bearing and axle sleeve union elbow is provided with O-ring seal, close using UN
Seal and O-ring seal have completely cut off the contact of the first precision bearing and the second precision bearing with medium, it is therefore prevented that medium is to first
The equipment such as precision bearing and the second precision bearing cause to corrode, and the service life of equipment are extended, between said inner tube and shell
It is provided with connecting tube, the side that the connecting tube is located at inner tube is provided with steel ball, and connecting tube is located at shell side and is provided with interior six
Angle screw, the connecting tube between the soket head cap screw and shell have been peripherally installed with red copper pad.
Preferably, the material of the UN sealing ring is polyurethane material.
The beneficial effects of the utility model are: the structure design of the utility model is reasonable, by the use of UN sealing ring, reduce
Abrasion, extends the service life of equipment, using precision bearing, keeps rotary joint operating persistently reliable, firm flexibly, friction
Coefficient is small, realizes the safety to run at high speed, reliability.

It is connected to shaft joint 4, the side of the rear end cap 3 is connected with axle sleeve union elbow 5, is provided with inner tube 6 in the shell 1, into
The circulation of row medium, the both ends of said inner tube 6 are respectively arranged with the first precision bearing 7 and the second precision bearing 8, make rotary joint
Smooth running is persistently reliable, firm flexibly, coefficient of friction is small, and first precision bearing 7 is located at close to one end of drive end bearing bracket 2,
Second precision bearing 8 is located at close to one end of rear end cap 3, and the junction of first precision bearing 7 and shaft joint 4 is set
Be equipped with UN sealing ring 9, the material of the UN sealing ring 9 is polyurethane material, reduce abrasion, second precision bearing 8 and
The junction of axle sleeve union elbow 5 is provided with O-ring seal 10, using UN sealing ring 9 and O-ring seal 10, has completely cut off first
The contact of precision bearing 7 and the second precision bearing 8 with medium, it is therefore prevented that medium is to the first precision bearing 7 and the second precision bearing 8
Etc. equipment cause to corrode, extend the service life of equipment, connecting tube 11, the company be provided between said inner tube 6 and shell 1
The side that adapter tube 11 is located at inner tube 6 is provided with steel ball 12, and connecting tube 11 is located at 1 side of shell and is provided with soket head cap screw 13, institute
The connecting tube 11 stated between soket head cap screw 13 and shell 1 has been peripherally installed with red copper pad 14.
The above description is only a preferred embodiment of the present invention, therefore all according to described in the utility model patent application range
