滑动磨擦 meaning in Chinese

break out friction
sliding friction

Table 2 : the loading p , abrasion linear velocity v , pv value and abrasion coefficient of some materials
表2几种材料的负载p滑动磨擦线速度v pv值和摩擦系数
If the using abrasion speed is low and the loading is not very big , but it undertakes heavy impact when running , it is better to apply thick wall shaft liner , for if the wall is too thin , the rigidity is not enough
如果使用滑动磨擦速度较低，负载不是很大，但运转时受很大的冲击，此时应采用厚壁轴套。如果轴套壁薄，刚度不足，可与金属外套复合使用。
