判断托辊好坏的标准有以下几条：
Criteria to judge good or bad rollers were the following:
托辊径向跳动量；托辊灵活度；轴向窜动量。
Radial roller capacity; roller flexibility; axial runout.
在国家规定的跳动量的范围内，可以保持胶带机平稳运行，否则就会使得胶带输送机胶带共振跳动，造成物料抛洒，污染环境，在带速越高的情况下越显得径向跳动量小的好处。我国国家标准规定量为0.7毫米，日本JIS标准规定的量为0.5毫米。
The amount prescribed by the state beating in the context of, you can maintain the tape machine running smoothly, otherwise you will make conveyor belt resonance beating, resulting in material spilled, polluting the environment, in the case with the higher speed, the more amount of small radial benefits. China\'s national standard is 0.7 mm, the Japanese JIS standard specifies the amount of 0.5 mm.
在胶带输送机运行过程中，如果托辊灵活度不好，旋转阻力系数高的时候，整个胶带输送机系统就得付出更大的动力，消耗更多的电力，有时还会造成胶带撕裂，电机烧毁的情况，更严重的时候可以引起火灾。针对这种情况，长期的技术研究反复的测试检验，设计、选型了旋转阻力系数低（最好低于0.020）的托辊。
In the belt conveyor is running, if not good roller flexibility, high spin drag coefficient, the entire belt conveyor system would have to pay a higher power, consume more power, sometimes resulting tape tear,Motor burned, and more time can cause serious fires. In response, long-term technology research and repeated testing testing, design, selection of a rotating low drag coefficient (preferably less than 0.020) in roller
