Wear-resisting plate for bridge support
The invention discloses a wear-resisting plate for a bridge support, which is characterized in that the wear-resisting plate adopts a high-molecular polymer matrix, a rubbed surface of the matrix is provided with groove rows and pit rows which are alternately arranged, and each groove row is a sine curve-shaped groove; and each pit row is formed by alternately arranging two kinds of ellipsoidal pits with different orientations. After the sine curve-shaped grooves and the diversion ellipsoidal pits are compounded, a vortex enhancement effect is achieved, rolling-shaft-like movement can be formed, sliding friction is converted into rolling friction, the effects of friction reduction and friction coefficient stabilization of pit-type textures are achieved, and the effect of wear resistance enhancement of groove-type textures is achieved. And the sine curve-shaped grooves and the ellipsoidal pits which have effects in reciprocating motion are used, and the test result shows that the friction coefficient reduction rate of the wear-resisting plate is as high as 31% or above compared with a blank sample without a texture on the surface.
本发明公开了一种桥梁支座用耐磨板，耐磨板采用高分子聚合物基体，基体的受摩擦面设有交替排列的沟槽列和凹坑列，每一沟槽列为一条正弦曲线形沟槽；每一凹坑列由两种不同朝向的椭球形凹坑交替排列而成。正弦曲线形沟槽与导流椭球形凹坑的复合后具有涡流增强效应，能形成类似滚轴运动，将滑动摩擦转化为滚动摩擦，既具有凹坑类织构减摩和稳定摩擦系数的效果，还具有凹槽类织构的增强耐磨性能的效果，并使用了在往复运动中均有效果的正弦曲线形沟槽和椭球形凹坑，试验结果表明，该耐磨板相对于表面无织构的空白样品，摩擦系数降低率高达31％以上。
