調(diào)速器前殼加工工藝與工裝設(shè)計(jì)
摘要：本次畢業(yè)設(shè)計(jì)題目是調(diào)速器前殼加工工藝與工裝設(shè)計(jì)。本人致力于調(diào)速器前殼的工藝與工裝的設(shè)計(jì)，前殼是調(diào)速器箱體的一個(gè)重要零件。調(diào)速器的零部件安裝于殼體內(nèi)，主要通過調(diào)速器箱控制動元件的快慢運(yùn)動。調(diào)速器是用來保持柴油機(jī)的轉(zhuǎn)速穩(wěn)定的。在柴油機(jī)的負(fù)載變化的過程中，它的轉(zhuǎn)速是會相應(yīng)發(fā)生變化的。當(dāng)轉(zhuǎn)速降低時(shí)，如果調(diào)速器不調(diào)節(jié)，柴油機(jī)最終將停掉；當(dāng)轉(zhuǎn)速升高時(shí)，如果調(diào)速器不作用，柴油機(jī)最終將無法承受過大的離心力而損壞。調(diào)速器的作用就是保持柴油機(jī)的轉(zhuǎn)速穩(wěn)定。另外調(diào)速器還可以保持柴油機(jī)的最低轉(zhuǎn)速和最高轉(zhuǎn)速，防止低轉(zhuǎn)速運(yùn)轉(zhuǎn)時(shí)熄火和高轉(zhuǎn)速運(yùn)轉(zhuǎn)時(shí)“飛車”，造成機(jī)械損壞。運(yùn)行時(shí)，柴油機(jī)所帶的負(fù)載是不斷變化的。在負(fù)載變化時(shí)，特別是突然變化時(shí)，必須保持柴油機(jī)的轉(zhuǎn)速穩(wěn)定。調(diào)速器就是自動保持轉(zhuǎn)速穩(wěn)定的裝置。對于發(fā)電用的柴油機(jī)，要求其轉(zhuǎn)速基本恒定在同步轉(zhuǎn)速，對調(diào)速器的調(diào)速特性要求很高。而調(diào)速器前殼是調(diào)速器的工作場所（調(diào)速器主要安裝于殼體內(nèi)）。其工藝工裝設(shè)計(jì)的是否合理將會直接關(guān)系到油泵能否正常的工作，從而影響調(diào)速器的性能指標(biāo)。關(guān)鍵字：調(diào)速器 調(diào)速器箱 柴油機(jī)
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.
