托辊是带式输送机用量最多的旋转部件,托辊的质量特性、使用寿命对带式输送机的运行效率和可靠性有很大影响。在 GB10595-89《带式输送机技术条件》中,对托辊的质量制定了严格的标准。1 问题提出托辊的径向跳动、旋转阻力、轴向位移量和焊缝焊接质量是衡量托辊质量优劣的4个重要指标。其中
Roller is the largest amount of belt conveyor rotating parts, roller quality characteristics, service life of the belt conveyor operation efficiency and reliability have a significant impact. In GB10595-89 “belt conveyor technology”, the quality of the roller has set a strict standard. 1 PROBLEMS It is proposed that the roller runout, rotational resistance, axial displacement and weld quality are four important indexes to measure the quality of roller. among them
