It can be the connection of two element internals.For the ordinary skill in the art, may be used
Above-mentioned term concrete meaning in the present invention is understood with concrete condition.
As shown in drawings, the invention provides the hydraulic swivel head with built-in oil circuit, including case
Body 6, case lid 7, input assembly and output assembly,
Case lid 7 is arranged on the upside of casing 6；
Input assembly is arranged on case lid 7；
Output assembly includes output gear component 2 and output flange 1；
Output gear component 2 is arranged on casing 6, and is connected with input assembly, can be defeated
Enter assembly to drive；
The two ends of output gear component 2 are provided with output flange 1, and output flange 1 is provided with
Connect the interface of hydraulic pressure pipe slips assembly；
The first oil duct 16 it is provided with in output flange 1；
The two ends of output gear component 2 are provided with the second oil duct connected with the first oil duct 16
17；
Seal ring set 3 is installed outside output gear component 2；
Seal ring set 3 is arranged between case lid 7 and output flange 1；
Annular oil groove 11 it is provided with inside seal ring set 3；
Annular oil groove 11 connects with the second oil duct 17；
The outside of seal ring set 3 is provided with logical hydraulic fluid port 12, connects with annular oil groove 11.
Seal ring set 3 is set outside output gear component 2, can effectively prevent hydraulic pressure
Oil sprays from output gear component 2.
Owing to two ends are provided with output flange 1, make output gear component 2 relatively big, for convenience
The manufacture of output gear component 2, can be set to a gear ring by output gear component 2,
And gear ring is fixedly installed on the outside of a hollow cylinder, form output gear wheels
Part 2, and output flange 1 is arranged on the two ends of hollow cylinder.
Annular oil groove 11 is set inside seal ring set 3, connects with the second hydraulic oil port 9,
The most no matter how output gear component 2 rotates, and hydraulic oil all can be transported to annular oil
In groove 11.
Logical hydraulic fluid port 12 is set in the outside of seal ring set 3, is allowed to be connected with annular oil groove 11
Logical.When the first hydraulic oil port 8 oil-feed on the output flange 1 of lower end, from output gear wheels
One of them second hydraulic oil port 9 of part 2 exports and then in annular oil groove 11, then pass through
Logical hydraulic fluid port 12 exports, and enters another annular oil groove 11 by another logical hydraulic fluid port 12 afterwards,
The first hydraulic oil port 8 on the output flange 1 of upper end is entered by the second hydraulic oil port 9,
Hence in slips assembly, it is achieved the lubrication to slips assembly.

Between produce friction, protect casing 6, extend the service life of casing 6.
High pressure rotary sealing part 10 it is provided with between seal ring set 3 and output gear component 2；
High pressure rotary sealing part 10 is arranged on the both sides of annular oil groove 11, is used for preventing hydraulic pressure
Oil is from annular oil groove 11 internal leakage.
High pressure rotary sealing part 10 is set between seal ring set 3 and output gear component 2,
It is disposed at the both sides of annular oil groove 11, is mainly used in preventing hydraulic oil from annular oil groove
11 internal leakages out, and then throw away from the outside of output gear component 2, cause waste.
High pressure rotary sealing part 10 is for rotating Glais ring.
Rotate Glais ring to be combined by a rubber o-ring and politef circle, material
For PTFE+NBR, in particular cases rubber elastomer NBR NBR uses polyfluoroprene FKM.
It can be divided into hole Glais ring and axle lattice to enclose, but its sealing function is the same, according to it
The deformation of itself produces higher initial contact stress to sealing surfaces, stops no pressure liquid
Leakage.During hydraulic cylinder works, pressure fluid is begun by the elastic deformation of ○-shaped seal ring
Limits ground extruding square seal ring, is allowed to be close to sealing surfaces and produces higher with pressure
The supplementary contact stress that the pressure of liquid increases and increases, and together with initial contact stress altogether
With the leakage stoping pressure fluid.
Therefore, in the present embodiment, high pressure rotary sealing part 10 uses Glais ring, and it can be
Axle Glais ring, it is also possible to be hole Glais ring, use hole lattice in the present embodiment
Lai Quan, will Glais ring be arranged on seal ring set 3 again with the axis body of output gear component 2
Coordinate and seal.
