The most important component in being.Hydraulic steering gear is turned a kind of cycloid rotary valve that stator pair forms by follow-up rotary valve and a width cycloid
Formula all-hydraulic steering gear.It is all-hydraulic with oil feed pump, overflow valve (or flow divider), steering cylinder and other connection attachment compositions
Steering.
Sealing ring of the existing hydraulic steering gear at input shaft when mounted, is pressed into shell by sealing ring press-loading head
's.Sealing ring is manually installed in before press fitting on press-loading head by operator.Mistake proofing step is carried on press-loading head, sealing ring relies on
Lip and the fitting of press-loading head axle portion are compressed to prevent sealing ring from being slid from press-loading head, then are pressed into shell by press-loading head.Because
Sealing ring is to place manually, is easy artificially to cause sealing ring slant setting on press-loading head.Mistake proofing step is easy to pluck out sealing ring
Spring causes assembly defect.Situation above all be easy to cause steering gear oil leak.
A kind of circumferencial direction uniform force is needed, the hydraulic sealing ring pressure for avoiding mistake that sealing ring is caused to tilt installation
Assembling structure.
Utility model content

The hydraulic sealing ring press mounting structure of installation.
A kind of hydraulic sealing ring press mounting structure, including：
Spindle nose is arranged in one end of press-loading head, the press-loading head, and the width of the spindle nose is less than the width of press-loading head, the pressure
Fill the contact position of head and spindle nose, the axial setting vacuum tube of press-loading head；
Counterbore is arranged in the inside of shell, the shell, and the counterbore is coordinated by sealing ring and spindle nose, the sealing ring
Packing spring is arranged in inside, and the inside of the packing spring is arranged sealing ring lip, is set on the outside of the packing spring
Set vacuum chamber, the packing spring, sealing ring lip and vacuum chamber are located at the contact position of press-loading head and spindle nose.
The press-loading head is cylinder.
The spindle nose is cylinder, and spindle nose axle center is overlapped with press-loading head axle center.
The vacuum tube is circular through hole, is evenly distributed on the surrounding of press-loading head.
The packing spring is annulus, and section is circle.
The sealing ring lip is stretched out towards the inside of sealing ring.
Spindle nose is arranged in one end of the utility model press-loading head, and the width of spindle nose is less than the width of press-loading head, press-loading head and axis
The contact position of head, the axial setting vacuum tube of press-loading head；Counterbore is arranged in the inside of shell, and counterbore is matched by sealing ring and spindle nose
It closes, packing spring is arranged in the inside of sealing ring, and sealing ring lip, the outside of packing spring is arranged in the inside of packing spring
Setting vacuum chamber, packing spring, sealing ring lip and vacuum chamber are located at the contact position of press-loading head and spindle nose.The utility model is justified
Circumferential direction uniform force avoids mistake that sealing ring is caused to tilt installation.

Specific implementation mode
Below in conjunction with the drawings and specific embodiments, the utility model is described further.
A kind of hydraulic sealing ring press mounting structure, including：Spindle nose 2, the width of spindle nose 2 is arranged in one end of press-loading head 1, press-loading head 1
Degree is less than the width of press-loading head 1, the contact position of press-loading head 1 and spindle nose 2, the axial setting vacuum tube 3 of press-loading head 1；Shell 5, shell
Counterbore is arranged in the inside of body 5, and counterbore is coordinated by sealing ring 4 and spindle nose 2, and packing spring 41 is arranged in the inside of sealing ring 4, close
The inside setting sealing ring lip 42 of seal spring 41, the outside setting vacuum chamber 43 of packing spring 41, packing spring 41,
Sealing ring lip 42 and vacuum chamber 43 are located at the contact position of press-loading head 1 and spindle nose 2.
Press-loading head 1 is cylinder.Spindle nose 2 is cylinder, and 2 axle center of spindle nose is overlapped with 1 axle center of press-loading head.Vacuum tube 3 is circle
Through-hole is evenly distributed on the surrounding of press-loading head 1.Packing spring 41 is annulus, and section is circle.Sealing ring lip 42 is towards close
The inside of seal 4 is stretched out.
Cancel mistake proofing step, increases blank pipe 3 really in press-loading head 1.After sealing ring 4 is installed to press-loading head 1, sealing ring 4
