摘 要
隨著機(jī)械加工行業(yè)的快速發(fā)展，對(duì)機(jī)床設(shè)備要求越來(lái)越高，數(shù)控機(jī)床已廣泛應(yīng)用。
1、在機(jī)床傳動(dòng)系統(tǒng)中，同步帶傳動(dòng)應(yīng)用越來(lái)越廣。因?yàn)樗涯Σ羵鲃?dòng)改善為嚙合傳動(dòng)，避免了打滑，傳動(dòng)精神準(zhǔn)確，效率高，傳動(dòng)比大，功率高?，F(xiàn)在已初步系列化，標(biāo)準(zhǔn)化，帶輪和同步帶可以直接購(gòu)買(mǎi)。
2、軸用來(lái)支承回轉(zhuǎn)零件或同時(shí)傳遞運(yùn)動(dòng)和動(dòng)力，軸的結(jié)構(gòu)設(shè)計(jì)就是確定軸的外形和全部結(jié)構(gòu)尺寸。影響軸的結(jié)構(gòu)因素很多，如軸在機(jī)器中的安裝位置形式；作用在軸上的載荷性質(zhì)、大??；零件在軸上的位置及其和軸的聯(lián)接方式；軸的加工工藝和裝配工藝等，所以軸沒(méi)有標(biāo)準(zhǔn)的結(jié)構(gòu)形式，設(shè)計(jì)時(shí)應(yīng)對(duì)不同情況進(jìn)行具體分析。對(duì)一般軸的結(jié)構(gòu)設(shè)計(jì)要求是：1）軸和軸上零件有準(zhǔn)確的工作位置；2）軸上各零件應(yīng)有可靠的相對(duì)固定；3）良好的制造和安裝工藝性；4）形狀、尺寸應(yīng)有利于減少應(yīng)力集中。
3、滾珠絲杠傳動(dòng)是在絲杠和螺母之間放入適當(dāng)數(shù)量的滾珠，使絲械和螺母之間的摩擦由普通絲杠的滑動(dòng)摩擦改善為滾動(dòng)摩擦的一種螺旋傳動(dòng)裝置。其作用是裝旋轉(zhuǎn)運(yùn)轉(zhuǎn)變?yōu)橹本€運(yùn)動(dòng)，它由滾珠絲杠、螺母、滾珠、滾珠循環(huán)返回裝置等零件組成。其特點(diǎn)為：摩擦小，逆正效率高；磨損小，壽命長(zhǎng)；通過(guò)預(yù)緊可消除軸向間隙，提高傳動(dòng)精度；不自鎖；結(jié)構(gòu)較復(fù)雜，工藝性差，成本高。
4、零件加工應(yīng)遵循基本的機(jī)械加工順序安排：先粗后精，先面后孔，先主后次，基面先行，熱處理按段穿插，檢驗(yàn)按需安排，完善加工工藝體系可以保證和提高產(chǎn)品的質(zhì)量，提高勞動(dòng)生產(chǎn)率，降低成本。
