托辊径向跳动量对胶带输送机的影响：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 influence of the radial runout of the roller to the belt conveyor: in the range of the country's prescribed beat quantity, the belt conveyor can be kept smoothly, otherwise the belt conveyer belt will resonate, the material is thrown, the environment is polluted and the more radial runout is smaller in the case of the higher speed. The national standard stipulated in our country is 0.7 millimeters, and the volume stipulated in the Japanese JIS standard is 0.5 millimeters.

托辊灵活度对胶带输送机的影响：在胶带输送机运行过程中，托辊的灵活度显得非常的重要，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。所以，选用旋转阻力系数低（最好低于0.020）的托辊是胶带输送机设计、选型的重要内容。

The impact of the roller spirit activity on the belt conveyor: in the operation of the belt conveyor, the flexibility of the roller is very important. If the roll flexibility is not good and the coefficient of rotation resistance is high, the whole belt conveyor system will have to pay more power, consume more electricity, and sometimes cause the tape to tear. The situation of motor burn can cause fire when it is more serious. Therefore, the selection of idlers with low rotational resistance coefficient (preferably below 0.020) is an important part of belt conveyor design and selection.

轴向窜动量对胶带输送机的影响：我国的胶带输送机制造技术越来越先进，但是轴线窜动还是一个需要重点研究的课题，因为我国的胶带制造技术，胶带输送机安装技术还和世界上先进国家有较大的差距，往往会出现胶带跑偏的情况，如果托辊的轴向窜动量大，就会造成托辊的较早损坏。一般轴向窜动量控制在0.5-0.7毫米以内较好。

The influence of the axial channeling on the belt conveyor: the manufacturing technology of the belt conveyer is more and more advanced in our country, but the axis movement is still a subject which needs to be studied emphatically. Because of the rubber belt manufacturing technology in our country and the installation technology of the belt conveyor, there is a big gap between the advanced countries in the world and the belt deviation often occurs. In case of the large axial movement of the idler, the idler will be damaged earlier. The general axial momentum is less than 0.5-0.7 mm.
