摘 要
機(jī)床是機(jī)械加工的重要設(shè)備，在機(jī)械制造中占有重要的地位。在一般的機(jī)器制造中，機(jī)床所擔(dān)負(fù)的加工工作量占總制造工作量的40%－60%，機(jī)床在國(guó)民經(jīng)濟(jì)現(xiàn)代化的建設(shè)中起著重大作用。本次設(shè)計(jì)的題目是CK6125機(jī)床主傳動(dòng)設(shè)計(jì)。設(shè)計(jì)內(nèi)容包括：確定有關(guān)尺寸參數(shù)、運(yùn)動(dòng)參數(shù)及動(dòng)力參數(shù)；據(jù)所求得的有關(guān)運(yùn)動(dòng)參數(shù)及給定的公比，寫(xiě)出結(jié)構(gòu)式，校驗(yàn)轉(zhuǎn)速范圍，繪制轉(zhuǎn)速圖；確定各變速組傳動(dòng)副的傳動(dòng)比值，定齒輪齒數(shù)、帶輪直徑，校驗(yàn)三聯(lián)滑移齒輪齒頂是否相碰，校驗(yàn)各級(jí)轉(zhuǎn)速的轉(zhuǎn)速誤差；繪制傳動(dòng)系統(tǒng)圖。
關(guān)鍵詞: 參數(shù)；傳動(dòng)比；結(jié)構(gòu)式；轉(zhuǎn)速圖；轉(zhuǎn)速誤差；傳動(dòng)系統(tǒng)圖
ABSTRACT
Lathe is an important machining equipment, machinery and holds an important position. In the general machinery manufacturing, machine processing shouldered by the total manufacturing work accounts for 40-60% of the workload. Machine modernization of the national economy building plays a major role. The design is Ordinary main drive design. Rebuild right design for the main drive to master machine side case design, and machine tools can reasonably determine the main technical parameters; Transmission master machine design and the calculation method; structural design and master the method of calculation, and so on. Design elements include: a parameter to determine the size, movement parameters and dynamic parameters; According to the two sought by the movement parameters and to the transmission ratio, as well structured and testing speed, rendering ageing period; to determine the variable speed drive Group Vice drive ratio gear teeth fixed, pulley diameter, Check triple Top Gear slip whether a collision speed calibration levels of speed error; Drawing drive system diagram.
Keywords: parameter; transmission ratio; structured; ageing period; speed error; drive system diagram.
