调速器前壳加工工艺与工装设计
摘要：本次文档设计题目是调速器前壳加工工艺与工装设计。本人致力于调速器前壳的工艺与工装的设计，前壳是调速器箱体的一个重要零件。调速器的零部件安装于壳体内，主要通过调速器箱控制动元件的快慢运动。调速器是用来保持柴油机的转速稳定的。在柴油机的负载变化的过程中，它的转速是会相应发生变化的。当转速降低时，如果调速器不调节，柴油机最终将停掉；当转速升高时，如果调速器不作用，柴油机最终将无法承受过大的离心力而损坏。调速器的作用就是保持柴油机的转速稳定。另外调速器还可以保持柴油机的最低转速和最高转速，防止低转速运转时熄火和高转速运转时“飞车”，造成机械损坏。运行时，柴油机所带的负载是不断变化的。在负载变化时，特别是突然变化时，必须保持柴油机的转速稳定。调速器就是自动保持转速稳定的装置。对于发电用的柴油机，要求其转速基本恒定在同步转速，对调速器的调速特性要求很高。而调速器前壳是调速器的工作场所（调速器主要安装于壳体内）。其工艺工装设计的是否合理将会直接关系到油泵能否正常的工作，从而影响调速器的性能指标。关键字：调速器 调速器箱 柴油机
Governor and the former Shell tool design process
Abstract：The graduation project topic is the former governor shell processing technology and tooling design. I am committed to the former governor shell process and tooling design, the former governor tank shell is an important part. Governor parts are installed in the shell, mainly through the governor control of dynamic components of the speed box movement. Governor is used to keep the engine speed and stability. Changes in the process of loading the diesel engine, its speed will change accordingly. When the speed is reduced, if the governor does not adjust, engine eventually stopped; when the speed increases, if the governor does not function, can not afford diesel will eventually damage the centrifugal force is too large. The role of governor is to keep the engine speed stability. Another governor can maintain the minimum speed and maximum engine speed to prevent the extinction and low speed running at high speed when the "speed", resulting in mechanical damage. Running, engine load is carried by the ever-changing. When the load changes, especially sudden changes, the need to maintain the engine speed stability. Governor is a device that automatically maintains speed stability. Diesel engines for power generation, asking them to speed almost constant in the synchronous speed, the speed characteristics of the governor demanding. The governor is the governor before the shell of workplace (governor mainly installed in the shell.) The technology and equipment design is reasonable will be directly related to the pump can work properly, thus affecting the governor's performance.
