在摩擦运动中保护钢丝绳的托辊，主动力源于绳辊间的摩擦力。对其保护性能的影响不仅有所处环境和提升物理过程因素，而且还有托辊自身的布局结构中的诸多因素。托辊有自身的运动待征，也应有与之适应的布局结构，这是发挥最佳保护能力的先决条件。从本质上讲．托辊的摩擦运动 In frictional movement to protect the rope roller, the main source of friction between the rope roller. The impact on its protective performance is not only the environment and the physical process to enhance the factors, but also the roller’s own layout of the many factors. Idler has its own movement to be sign, there should be adapted to the layout of the structure, which is to play the best protection of preconditions. Essentially. Roller friction movement
