辊道的传动形式有集体传动，单独传动和空转辊道三种。
①集体传动辊道——由一台电动机同时带动所有的或其中一部分辊子。通常是4~10根辊子。
②单独传动辊道——每个辊子或每两个辊子由一个单独电动机带动。
The drive form of the roller table has three types: collective drive, single drive and roller table.
(1) a collective drive roller - a motor that drives all or some of the rollers at the same time. It is usually the 4~10 root roller.
(2) a separate drive roller track - each roller or two rollers are driven by a single motor.
皮带输送机的常规设计方法所存在的问题带式输送机常规设计方法实际上是一种安全或是偏于保守的设计方法。例如。选用的输送带安全系数、运行阻力系数偏大，从而造成选用的电动机功率过大，带宽过宽或是抗拉强度要求较高。
The conventional design method of belt conveyor is a safe or cervative design method. For example. The safety factor and the running resistance coefficient of the selected conveyor belt are too large, resulting in excessive power selection, wide bandwidth or high tensile strength.
皮带输送机的结构参数的优化方法皮带输送机的结构虽然受到了种种工况的限制，而输送机的工作状态是处于满载正常运行的状态，在常规设计计算方法完成后，可以进行采用离散变量优化的网络法，对带式输送机参数进行优化设计 。
Optimization of the structural parameters of belt conveyer, the structure of belt conveyer is restricted by various working conditi, and the working state of the conveyor is in a state of full load. After the completion of the conventional design calculation method, the network method of discrete variable optimization can be used to optimize the parameters of the belt conveyor. Chemical design.
