專利名稱：一種螺桿壓縮機轉子的制作方法
技術領域：
本實用新型涉及ー種轉子，尤其涉及ー種螺桿壓縮機轉子。
背景技術：
螺桿壓縮機中，轉子的形狀基本上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，由于設計的取向不同，應該說各有各的優(yōu)缺點。但是，現在有技術存在的共同缺點是轉子直徑較小，線速度偏高，齒數比較多。在實際應用中會出現噪聲高，振動大，特別轉子齒形比較單薄，剛性不足，從而影響到加工效率，壓縮效率，使用壽命等一列問題
實用新型內容
本實用新型需要解決的技術問題是提供ー種增強剛性，降低線速，齒輪小且噪音低的螺桿壓縮機轉子。為解決上述技術問題，本實用新型采用以下技術方案ー種螺桿壓縮機轉子，包括陽轉子和陰轉子，其特征在于陽轉子和陰轉子的雙邊非対稱，其組成曲線均為圓弧或圓弧包絡線，陽、陰轉子的齒數比為4 5，陽轉子和陰轉子之間的間隙為0. 07 0. Ilmm,以陽轉子的中心為原點，陽轉子、陰轉子有間隙的實際型線的坐標如下
