摘要
针对煤矿井下胶筒液压卡盘存在垫板啃噬胶筒的问题,提出了采用翼片式卡瓦将垫板与卡瓦设计为整体的方法,运用将径向运动转化为平动基本原理计算出最佳的搭接距离和搭接厚度,通过分析翼片式卡瓦受力情况对其进行有限元仿真分析,从而进行优化改进。
In view of the coal mine rubber-sleeve type hydraulic chuck plate chew rubber sleeve problem,the vane slip integrating the plate and the slip for the overall design method was put forward,using the basic principle of translational radial motion can be converted to calculate the best lap distance and the thickness of the lap joint,through the analysis of blade slip stress distribution on the finite element simulation analysis,so as to optimize the improvement.
