Spherical hinge chuck component is one of hydraulic motor kernel component, plays a supporting role and holds in oil cylinder rotary course
Carry certain load.Motor long-play can cause certain abrasion to ball pivot.Therefore ball pivot is to influence the hydraulic motor life-span
One of critical component.At present, hydraulic motor ball pivot is mostly that copper alloy or iron alloy are made, and its wearability needs further to be carried
It is high.
Utility model content
The purpose of this utility model is to overcome above-mentioned the deficiencies in the prior art, there is provided a kind of height for hydraulic motor
Performance ball pivot, its wearability can be strengthened, ensure hydraulic motor operation stability, improve its life-span.
To achieve the above object, the utility model uses following technical proposals：A kind of high-performance ball for hydraulic motor
Hinge, it is step cutting pattern face that the ball, which twists inwall, is installed on oil cylinder cylinder step surface, and it is spherical convex surface that the ball, which twists outer wall, with
Concave spherical surface is mutually matched in chuck, and some equally distributed flat blind holes are provided with the spherical convex surface that the ball twists, described flat
Bottom blind hole axial line inwardly converges to the center of circle of spherical convex surface, and solid lubrication post, the solid profit are provided with the flat blind hole
Traveller outer face flushes with spherical convex surface.
As optimization, the gross area of the solid lubrication post outer face is the 25-33% of spherical convex surface surface area.
As optimization, the gross area of the solid lubrication post outer face is the 30% of spherical convex surface surface area.
As optimization, the flat blind hole depth is equal.
As optimization, it is copper alloy or ferrous alloys that the ball, which twists, and the solid lubrication post is high-purity core graphite.
The beneficial effects of the utility model are：The carrying face pressure of this ball pivot is more than 220Mpa, working face friction factor value
Less than 0.3；In the case of temperature is not higher than 120 DEG C, the performance of ball pivot carrier and solid lubrication post enhances liquid without significant changes
