專利名稱：一種螺桿壓縮機(jī)轉(zhuǎn)子的制作方法
技術(shù)領(lǐng)域：
本實(shí)用新型涉及一種轉(zhuǎn)子，尤其涉及一種螺桿壓縮機(jī)轉(zhuǎn)子。
背景技術(shù)：
螺桿壓縮機(jī)中，轉(zhuǎn)子的形狀基本決定了螺桿壓縮機(jī)的性能，目前世界上已有的有代表性的轉(zhuǎn)子型線主要有德國(guó)某公司的型線，瑞典某公司的型線，以及臺(tái)灣、日本等公司的型線，這些型線選取不同的曲線及其組合，由于設(shè)計(jì)取向不同，應(yīng)該說各有各的優(yōu)缺點(diǎn)。但是，現(xiàn)有技術(shù)存在的共同缺點(diǎn)是轉(zhuǎn)子直徑較小導(dǎo)致轉(zhuǎn)速高，在實(shí)際應(yīng)用中會(huì)出現(xiàn)噪聲、振動(dòng)大、剛性不足，從而影響使用壽命。
發(fā)明內(nèi)容
本實(shí)用新型的目的在于提供一種新型的螺桿壓縮機(jī)轉(zhuǎn)子，其設(shè)計(jì)取向是轉(zhuǎn)子間完全實(shí)現(xiàn)“曲面對(duì)曲面”的密封，而不包含任何“曲線對(duì)曲線”的密封，有助于形成流體動(dòng)力潤(rùn)滑膜，降低通過接觸帶的橫向泄漏，提高壓縮機(jī)效率；改善轉(zhuǎn)子的加工性能，便于采用磨削法加工，也更容易檢驗(yàn)；大轉(zhuǎn)子、低轉(zhuǎn)速，以降低噪聲和振動(dòng)，提高轉(zhuǎn)子剛性，延長(zhǎng)使用壽命。對(duì)加工精度、雜質(zhì)和油碳化物的敏感性小。
為克服現(xiàn)有技術(shù)的上述不足，本實(shí)用新型采用了如下技術(shù)方案，這種螺桿壓縮機(jī)轉(zhuǎn)子，包括陰轉(zhuǎn)子、陽轉(zhuǎn)子，陰轉(zhuǎn)子和陽轉(zhuǎn)子的雙邊非對(duì)稱，組成曲線為圓弧及其包絡(luò)線，陰陽轉(zhuǎn)子的齒數(shù)比為6∶5，陰陽轉(zhuǎn)子之間具有間隙，其特征在于以陰轉(zhuǎn)子的中心點(diǎn)為坐標(biāo)原點(diǎn)，陰陽轉(zhuǎn)子之間的間隙為0.02-0.06mm，其實(shí)際型線坐標(biāo)如下
具體實(shí)施時(shí)，陰陽轉(zhuǎn)子之間的間隙為0.05mm。
本實(shí)用新型與已有技術(shù)相比，由于采用了本型線使轉(zhuǎn)子間完全實(shí)現(xiàn)了“曲面對(duì)曲面”的密封，而不包含任何“曲線對(duì)曲線”的密封，有助于形成流體動(dòng)力潤(rùn)滑膜，降低通過接觸帶的橫向泄漏，提高壓縮機(jī)效率。由于完全采用了圓弧或圓弧包絡(luò)線，從而改善轉(zhuǎn)子的加工性能，便于采用磨削法加工，也更容易檢驗(yàn)。采用大轉(zhuǎn)子、低轉(zhuǎn)速設(shè)計(jì)思路后，可以降低噪聲和振動(dòng)，提高轉(zhuǎn)子剛性，延長(zhǎng)使用壽命，也對(duì)加工精度、雜質(zhì)和油碳化物的敏感性相對(duì)減小。

2.如權(quán)利要求1所述的一種螺桿壓縮機(jī)轉(zhuǎn)子，其特征是陰陽轉(zhuǎn)子之間的間隙為0.05mm。
專利摘要一種螺桿壓縮機(jī)轉(zhuǎn)子，其結(jié)構(gòu)包括雙邊為非對(duì)稱的陰轉(zhuǎn)子、陽轉(zhuǎn)子，它們的組成曲線為圓弧及其包絡(luò)線，齒數(shù)比為6∶5，且陰陽轉(zhuǎn)子之間具有間隙，其特征在于以陰轉(zhuǎn)子的中心點(diǎn)為坐標(biāo)原點(diǎn)，陰陽轉(zhuǎn)子之間的間隙為0.02－0.06mm，按其實(shí)際型線坐標(biāo)制造的轉(zhuǎn)子具有“曲面對(duì)曲面”、“大轉(zhuǎn)子、低轉(zhuǎn)速”的特點(diǎn)。本實(shí)用新型與已有技術(shù)相比，具有完全實(shí)現(xiàn)“曲面對(duì)曲面”密封，從而有助于形成流體動(dòng)力潤(rùn)滑膜，降低通過接觸帶的橫向泄漏，提高壓縮機(jī)效率；以及改善轉(zhuǎn)子的加工、檢驗(yàn)性能，采用大轉(zhuǎn)子、低轉(zhuǎn)速設(shè)計(jì)思路后，可以降低噪聲和振動(dòng)，提高轉(zhuǎn)子剛性，延長(zhǎng)使用壽命，相對(duì)減小對(duì)加工精度、雜質(zhì)和油碳化物敏感性的優(yōu)點(diǎn)。
