    带传动设计tape transport(中文3500字,英文2600字)
    在机械传动中传动有多种多样，V带式输送机在长距离的传动中起到了非常重要的竞争作用。传动系统将会变得更大、更复杂，而驱动系统也己经历了一个演变过程，并将继续这样下去。如今，带传动和多驱动系统需耍更大的功率，比如3驱动系统需耍给输送带750KW(成庄煤矿输送机驱动系统的要求)。控制驱动力和加速度扭矩是输送机的关键。一个高效的驱动系统应该能顺利的运行，同时保持输送带张紧力在指定的安全极限负荷内。为了负载分配在多个驱动上，扭矩和速度控制在驱动系统的设计中也是很重要的因素。由于输送机驱动系统控制技术的进步，目前更多可靠的低成本和高效驱动的驱动系统可供顾客选择[1]

    Among the methods of material conveying quantity, belt conveyors play a very important part in the reliable carrying of material over long distances at competitive cost. Conveyor systems have become larger and more complex and drive systems have a l so been going through a process of evolution and will continue to do so. Nowadays, bigger belts require more power and have brought the need for larger individual drives as well as multiple drives such as 3 drives of 750 kW for one belt(this is the case for the conveyor drives in Chengzhuang Mine). The ability to control drive acceleration torque is critical to belt conveyors' performance. A efficient drive system should be able to provide smooth, soft starts while maintaining belt tensions within the specified safe limits. For load sharing on multiple drives. torque and speed control are also considerations in the drive system's design. Due to the advances in conveyor drive control technology, at present many more reliable. Cost-effective and performance- driven conveyor drive systems covering a wide range of power are available for customers' choices[1].
