输送带在运行过程中，有的时候会出现跑偏的现象。一般情况，由于输送带本身问题引起输送带跑偏的情况并不多见，输送带的跑偏主要还是输送机的原因。输送机由于辊筒不平行、支架不垂直、辊筒转动不灵活的原因，均可引起输送带跑偏。对于比较短的输送带，由于单侧辊筒转动不灵活以及其他一些因素的几率比较大，输送带出现跑偏的可能性比较大，而长的输送带，由于托辊个数的增加，单侧影响的不对称性会减少，因此在输送带上表现出来的跑偏现象会变少。
In the process of conveyor belt operation, sometimes there will be deviation phenomenon. Generally speaking, the deviation of conveyor belt caused by the problem of conveyor belt itself is not common. The main reason for the deviation of conveyor belt is conveyor. Conveyor belt deviation can be caused by the reasons of non-parallel rollers, non-vertical support and non-flexible rollers rotation. For shorter conveyor belts, because of the flexibility of one-side rollers and other factors, the probability of conveyor belt deviation is greater, while for long conveyor belts, the asymmetry of one-side effects will be reduced due to the increase of the number of idlers, so the phenomenon of deviation on conveyor belts will change. Less.
当然，个别情况除外，如：调心托辊摆动不灵活或被倾斜固定时，辊筒表面不够清洁等，均可引起输送带跑偏。
Of course, exceptions to individual cases, such as the flexible swing of the adjusting roller or the inadequate cleaning of the surface of the roller when it is tilted and fixed, can cause the deviation of the conveyor belt.
