專利名稱：：一種螺桿壓縮機轉(zhuǎn)子的制作方法
技術(shù)領(lǐng)域：
：本實用新型涉及一種轉(zhuǎn)子，尤其涉及一種螺桿壓縮機轉(zhuǎn)子。技術(shù)背景螺桿壓縮機中，轉(zhuǎn)子的形狀基本決定了螺桿壓縮機的性能，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)計取向不同，應(yīng)該說各有各的優(yōu)缺點。但是，現(xiàn)有技術(shù)存在的共同缺點是轉(zhuǎn)子直徑較小導(dǎo)致轉(zhuǎn)速高，在實際應(yīng)用中會出現(xiàn)噪聲、振動大、剛性不足，從而影響使用壽命。
發(fā)明內(nèi)容本實用新型的目的在于提供一種新型的螺桿壓縮機轉(zhuǎn)子，其設(shè)計取向是轉(zhuǎn)子間完全實現(xiàn)"曲面對曲面"的密封，而不包含任何"曲線對曲線"的密封，有助于形成流體動力潤滑膜，降低通過接觸帶的橫向泄漏，提高壓縮機效率；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；大轉(zhuǎn)子、低轉(zhuǎn)速，以降低噪聲和振動，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，本實用新型釆用了如下技術(shù)方案，這種螺桿壓縮機轉(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)子的中心點為坐標原點，陰陽轉(zhuǎn)子之間的間隙為O.06-0.12鵬。具體實施時，陰陽轉(zhuǎn)子之間的間隙為0.10mm。本實用新型與已有技術(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，有助于形成流體動力潤滑膜，降低通過接觸帶的橫向泄漏，提高壓縮機效率。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。釆用大轉(zhuǎn)子、低轉(zhuǎn)速設(shè)計思路后，可以降低噪聲和振動，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。附圖為本實用新型陰陽轉(zhuǎn)子在直角坐標系中端面形狀示意圖。具體實施方式以下結(jié)合附圖對本實用新型的具體實施方案作詳細說明實施例一種螺桿壓縮機轉(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的中心點為坐標原點，陰轉(zhuǎn)子l、陽轉(zhuǎn)子2的有間隙的實際型線坐標如下序號陽轉(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〗3293.2634-35.072862.5871-35.090713393.3380-35.025162.5502-35.067013493.4124-34.977262.5133-35.043213593.6123-34,847862.1634-34.814913694.1342-34.502261.6428-34.465913794.6508-34.148761.1274-34.109013895.1621-33.787560.6176-33.744513995.6679-33.418760.1132-33.372314096.1680-33.042259.6145-32.992614196.6625-32.658359.1216-32.605414297.1511一32.267158.6345—32.210814397.6337-31.868558.1535-31'809014498.1104-31.462657.6785-31,399914598.5808-31.049657.2097-30.983714699.0450-30.629756
