带式输送机“飘带”问题探讨

Resently research on belt lifting off in use of belt conveyors

针对现有计算方法的不足，本文从柔索的力学理论出发，提出了一个新的保证不飘带的凹弧段最小曲率半径的计算公式；

Accordance with the problems of current calcu lation methods,based on the rnechanics principle of softrope,this paper presentes a new formula of calculatingthe catenary's minimum radius of curvature,with whichthe belt lifting off is avoided, and then analyses theforces on the pressing idlers when these are available:
