机械毕业设计（论文）-直角式可控调速装置机械系统的设计.docVIP

摘 要 在煤炭工业发展过程中，长距离、大运量、大功率的带式输送机的应用越来越广泛。而合理的带式输送机的驱动方式已成为长距离、大运量、大功率的带式输送机的一个瓶颈，因而我们要求带式输送装置具有较好的力矩。直角式可控调速装置就可满足该要求，可实现速度控制功能。 全套图纸，加 直角式可控调速装置是在原有普通的2K--H型行星齿轮减速器的基础上展开的，并进行了改良与创新，使得原有的单一减速功能变为由液压马达实现的可控调速的高性能的减速装置。该装置的设计采用了机械传动、液压传动与现代电器控制技术想结合，构思新颖独特，且方案在技术上是切实可行的，有一定的创新性。直角式可控调速装置总体结构简单，制造容易，并与采煤生产密切相结合，具有广泛的推广与应用前景。 关键词：直角 调速 行星齿轮 减速器 Abstract In the process of coal industry development in long distance,large capacity, high power belt conceyor application more and more widespread. Reasonable belt converor drivng mode has become a long distance, large capacitity, high power belt conveyor of a bottleneck. Therefore we request a belt conveying device has good torque. Right angle type controlled speed regulating device can meet the requirement, which can realize the speed control function. The right-angle type device that can control of changing the speed is a function in the original common 2K--H plant wheel gear , which to go forward the improvement and innovation, make the only-one lower the speed function change into be press by the liquid the motor carry out of can control to adjust the speed of the deceleration of high performance equip. This equipments design project adoption machine spreeds to move, the liquid presses to move control the technique with modern electric appliances to combine together, conceive outline novel, the project is on the technique is to slice actually viable, have the innovation and unique, the total structure is simple, make easily, the cost is low with adopting the coal production to combine together closely, having the extensive expansion application foreground.
