Such case, it is necessary to sanding and polishing again be carried out to wear-resistant ball, to ensure to grind quality.This results in wear-resistant ball to replace frequency
It is numerous, make production efficiency reduction and cost increases.
Invention content
Technical problems based on background technology, the present invention propose a kind of internal support type wear-resistant ball.
A kind of internal support type wear-resistant ball proposed by the present invention, including：Skeleton, supporting layer, hollow ball and wearing layer；
Skeleton is the hollow out sphere structure of the arcuate struts composition of more rotational symmetry distributions, and skeleton is mounted on hollow ball
Inside is simultaneously overlapped with the hollow ball centre of sphere；Supporting layer is the more straight-bars in each arcuate struts, and more straight-bars are hollow
Ball interior radial distribution spherical in shape, the extending direction of each straight-bar are overlapped with the radius of hollow ball；
Each straight-bar is correspondingly provided with a cambered surface respectively, and cambered surface is mounted on the one end of straight-bar far from skeleton, and the convex surface of cambered surface is pasted
It closes in hollow ball inner circumferential, straight-bar is from the concave surface of cambered surface against cambered surface；
Wearing layer is the spherical surface for being coated on hollow ball periphery of two hemispheres composition, two hemispheroidal edge difference
Equipped with the first extended surface and the second extended surface, the first extended surface and the second extended surface are equipped with the helicitic texture to match.
Preferably, hollow ball is equipped with injection hole, is dismantled at injection hole and is equipped with cock body.
Preferably, injection hole is cylindrical hole, and cock body is the cylinder that diameter is more than injection bore dia.

Preferably, straight-bar is spring lever.
A kind of internal support type wear-resistant ball proposed by the present invention, first, the setting of hollow ball is conducive to save wear-resistant ball
Cast raw material reduces cost；Secondly, by the setting of skeleton and supporting layer, it ensure that the result of wear-resistant ball is stablized.In particular, arc
The setting in face so that straight-bar is contacted with hollow ball dignity, hollow to improve to ensure that the uniform of hollow ball inner circumferential stress
The ability of anti-deformation of sphere, to be further ensured that the stable structure of wear-resistant ball.
In the present invention, in the wear-resistant ball course of work, wearing layer directly with polishing object contact, when wearing layer is worn,
Wear-resistant ball working performance is influenced, wearing layer can be directly replaced, not influence the continue working of wear-resistant ball.
Description of the drawings
Fig. 1 is a kind of internal support type wear-resistant ball structure chart proposed by the present invention.
Specific implementation mode
Referring to Fig.1, a kind of internal support type wear-resistant ball proposed by the present invention, including：Skeleton 1, supporting layer 2, hollow ball 3
With wearing layer 4.
Skeleton 1 is the hollow out sphere structure of the arcuate struts composition of more rotational symmetry distributions, and skeleton 1 is mounted on hollow ball
3 inside of body is simultaneously overlapped with 3 centre of sphere of hollow ball.Supporting layer 2 is the more straight-bar 2-1 in each arcuate struts, and more straight
Bar 2-1 in the radial distribution spherical in shape of the inside of hollow ball 3, the extending direction of each straight-bar 2-1 with the radius weight of hollow ball 3
It closes.In present embodiment, skeleton 1 is welded by more arcuate struts and is formed, to ensure the stable structure of skeleton.
Each straight-bar 2-1 is correspondingly provided with a cambered surface 2-2 respectively, and cambered surface 2-2 is mounted on the one end of straight-bar 2-1 far from skeleton 1,
The convex surface of cambered surface 2-2 is fitted in 3 inner circumferential of hollow ball, and straight-bar 2-1 is from the concave surface of cambered surface 2-2 against cambered surface 2-2, so as to straight-bar 2-
1 resists hollow ball 3, to ensure the stabilization of 3 structure of hollow ball.The setting of cambered surface 2-2 so that straight-bar 2-1 and hollow ball
3 face of body contacts, to ensure that the uniform of 3 inner circumferential stress of hollow ball, to improve the ability of anti-deformation of hollow ball 3, to
Ensure the stable structure of wear-resistant ball.In present embodiment, straight-bar 2-1 is spring lever.
In present embodiment, hollow ball 3 is equipped with injection hole 3-1, is dismantled at injection hole 3-1 and is equipped with cock body 3-2.Such as
