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。技術(shù)背景螺桿壓縮機(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)"曲面對曲面"的密封，而不包含任何"曲線對曲線"的密封，有助于形成流體動(dòng)力潤滑膜，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，延長使用壽命。對加工精度、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)用新型釆用了如下技術(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O.06-0.12鵬。具體實(shí)施時(shí)，陰陽轉(zhuǎn)子之間的間隙為0.10mm。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"曲面對曲面"的密封，而不包含任何"曲線對曲線"的密封，有助于形成流體動(dòng)力潤滑膜，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，便于釆用磨削法加工，也更容易檢驗(yàn)。釆用大轉(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，延長使用壽命，也對加工精度、雜質(zhì)和油碳化物的敏感性相對減小。附圖為本實(shí)用新型陰陽轉(zhuǎn)子在直角坐標(biāo)系中端面形狀示意圖。具體實(shí)施方式以下結(jié)合附圖對本實(shí)用新型的具體實(shí)施方案作詳細(xì)說明實(shí)施例一種螺桿壓縮機(jī)轉(zhuǎn)子(參見圖)，它包括陰轉(zhuǎn)子l、陽轉(zhuǎn)子2，陰轉(zhuǎn)子1和陽轉(zhuǎn)子2的雙邊非對稱，組成曲線均為圓弧或圓弧包絡(luò)線，陰轉(zhuǎn)子的齒數(shù)為6,陽轉(zhuǎn)子的齒數(shù)為5,陰陽轉(zhuǎn)子之間的間隙為O.lOmm,考慮到加工誤差問題，間隙可放寬至O.06-0.12mm。以陰轉(zhuǎn)子l的中心點(diǎn)為坐標(biāo)原點(diǎn)，陰轉(zhuǎn)子l、陽轉(zhuǎn)子2的有間隙的實(shí)際型線坐標(biāo)如下序號(hào)陽轉(zhuǎn)子陰轉(zhuǎn)子x2y2xlyi149.3319-49.662568.0270-52.5004249.4614-49.535468.1936-52.2821;49.6588-49.347968.3546-52.0596449.8596-49.164168.5100-51.832950.0640-48.984068.6597-51.6021650.2717-48.807868.8036-51.3674750.4829—48.635368.9416一51.1291<table>tableseeoriginaldocumentpage5</column></row><table>3557.7076-45.400b70.0^79—4i64643658.0246-45.337169.9954-43.37763758.3488-45.276469.9261-43.11053858.6810-45.218269.8499-42.84533959.0222-45.162469.7670-42.58204059.3735-45.108669.6774-42.32104159.7362-45.056869.5812-42.06244260.1117-45.006569.4784-41.80624360.5017-44.957669.3692-41.55284460.9081-44.909569.2535-41.30224561.3334-44.861969.1331-41.053161.7799-44.814469.0063-40.80724762.2509-44.766168.8734—40.56454862.7495-44.716468.7343-40.32534963.2800-44.664468.5891-復(fù)08975063.8466-44.608968.4380-39.85785164.4546-44.548468.2810-39.62985265.1098—44.481368.1182-39.40605365.8185—44.405267.9498-39.18635466.5882-44.317467.7758-38.97095567.4269-44.214367.5964-38.76015668.3433-44.091767.4117-38.55395769.3472-43.944267.2217-38.35245870.4486-43.765267.0267-38.15585971.6585-43.546566.8268-3796436072.9878-43.278666.6220-37.77796i74.4478-42.9497666.4126-37.59686276.0494—42.54616377,8027-42,05196479.7167-41.44846581.7987-40.71516684.0539-39.82846780.4846-38.76296888.2021-37.93966988.2858-37.89797088.3693-37.85627188.4528-37.81437288.5360-37.77237388.6191-37.73027488.7021-37.68807588.7849-37.64577688.8675-37.60327788.9500-37.56077889.0323-37.5〗817989.1145-37.47538089.1966-37.43258i89.2784-37.38968289.3602-37.34658389.4418-37.30348489.5232-37.26018589.6045-37.216889.6856-37.17338789.7666-37.12988889.8475-37.0861766.1985—37.421165.9801-37.250965.7574-37.086365.5306-36.927465.2998-36.774465.0652一36.627364.9737-36。572164.9360-36.549564.8984-36.527064.8607-36.5(M464.8231-3(3.481864.7855-36.459264.7479-36.436664.7103-36.413964.6727-36.39i264.6351-36.368564.5976-36.345864.5600-36,323164.5225-36.300364.4850-36.277664.4475-36.254864.4100-36.232064.3725-36.209164.3350-36.186364.2975-36.163464.2601-36.140564.2226-36.11768989.9282-37.042464.1852-36.09479090.0087-36.998564.1478-36.07189190.0891-36.954664.1104-36.04889290.1694-36.910564.0730-36.02589390.2495-36.866464.0356-36.00289490.3294-36.822163.9982-35.97989590.4093-36.777863.9609-35.9568%90.4889-36.733363.9235-35.93379790.5685-36.688863.8862-35.91069890.6479-36.644263.8489-35.88759990.727]-36.599463.8116-35.864410090.8062-36.554663.7743-35.841310190.8851-36.509763.7370-35.818110290.9640-36.464763.6997-35.794910391.0426-36.419663.6625-35.771710491.1212-36.374463.6252-35.748510591.1995-36.329163.5880-35.725310691.2778-36.283763.5508-35.70201079L3559-36.238363.5136-35.678810891.4338-36.192763.4763-35.6555i()99i.5117-36.147063.4392-35.632211091.5893-36.101363.4020-35.608811191.6669-36.055563.3648-35.585511291.7443-36.009563.3277-35.56211]391.8215-35.963563.2905-35.5387".491.8987-35.917463.2534-35.515311591.9757—35.871263.2163—35.491992.0525-35,825063.丄792-35.4684in92.1292-35.778663.142]-35.445011892.2058-35.732163.1050-35.4211992.2822-35.685663.0679-35.3980i2092.3585-35.639063,0309-35.3745i2192.4346-35.592262.9938—M"0912292.5107-35.545462.9568-35.327412392.5865-35.498662.9198-35.303812492.6623-35.451662.8827-35.280212592.7379-35.404562.8458一35.25"12692.8134-35.357462.8088-35.233012792.8887-35.310262.7718-35.209312892.9639-35.262962.7348-35.185612993.0390-35.215462.6979-35.161913093.1140-35.168062.6610-35.138213193.1888-35.120462.6240-35.1145〗3293.2634-35.072862.5871-35.090713393.3380-35.025162.5502-35.067013493.4124-34.977262.5133-35.043213593.6123-34,847862.1634-34.814913694.1342-34.502261.6428-34.465913794.6508-34.148761.1274-34.109013895.1621-33.787560.6176-33.744513995.6679-33.418760.1132-33.372314096.1680-33.042259.6145-32.99261
