设计简介
摘要 液压系统是以电机提供动力基础，使用液压泵将机械能转化为压力，推动液压油。通过控制各种阀门改变液压油的流向，从而推动液压缸做出不同行程、不同方向的动作。完成各种设备不同的动作需要。液压系统已经在各个工业部门及农林牧渔等许多部门得到愈来愈广泛的应用，而且愈先进的设备，其应用液压系统的部分就愈多。所以像我们这样的大学生学习和亲手设计一个简单的液压系统是非常有意义的。

Abstract The special milling machines, hydraulic system design in the design programme and the hydraulic system shall be able to finish the work into fast forward, and backed out when the milling machine architecture to understand and grasp for the hydraulic knowledge on the basis of from a given conditions, and the value analysis of the theory with practice, the work of drawing in autocad software diagram of the hydraulic system, the principle of the assembly drawing and analyzing the parts, the process, Set down to a time too short, the time of the short, at the start of the larger, slow down a short time will result in oscillatory too much, so damage to equipment, make failure of the jug, the main argument is based on innovation innovation power, the motor drivers head first, revolution speed and work in the process of the maximum load and the itinerary for design calculations. Friction factor is also a need to think of it. although friction of the relatively small, but will also be affected. the design of the difficulty is mainly the principle of the analysis and design purpose is to achieve appropriate control, and to choose a relative rationality, high precision, economically affordable hydraulic components, and design talents widely used.
Key words hydraulic transmission, control system, hydraulic system.
