螺桿式壓縮機轉子的制作方法

專利名稱：螺桿式壓縮機轉子的制作方法
技術領域：
本實用新型涉及一種螺桿式壓縮機轉子。
背景技術：
在螺桿式壓縮機中，需要用于螺桿轉子，在工作過程中，陰轉子上的陰轉子齒與陽轉子 上的陽轉子齒互相嚙合，陰轉子齒與陽轉子齒的設計對壓縮機的工作性能具有重要影響，但 目前的螺桿式壓縮機設計尚存在如下缺點-,
1、 陰轉子齒、陽轉子齒的型線設計不合理，兩者嚙合不平穩，使得壓縮機在工作過程 中噪音大、密封性差、效率低；
2、 現有陰轉子齒、陽轉子齒設計不合理，導致齒的強度低，容易損壞。
發明內容
本實用新型的目的在于提供一種螺桿式壓縮機轉子，其中陰轉子、陽轉子嚙合平穩、噪 音小、密封性好、工作效率高。
本實用新型是通過以下技術方案來實現的-
一種螺桿式壓縮機轉子，包括有陰轉于及陽轉子，陰轉子的陰轉子齒與陽轉子的陽轉子 齒互相嚙合；各陰轉子齒、陽轉子齒的外輪廓型線分別由以下各離散點依次連接而成陽轉子 陰轉子

前述坐標值可以采用任一長度單位(如均為毫米)，因為只要壓縮機轉子具有都述形狀 的型線即可，其具體尺寸可按相同比例放大或縮小。
所述陰轉子齒與所述陽轉子齒的數量不等，優選的，所述陰轉子齒的數量多于所述陽轉
于齒的數量，如所述陰轉子齒為7個，所述陽轉子齒為5個。
本實用新型相對于現有的螺桿式壓縮機轉子來說，由于轉子采用不對稱結構，作為主動 轉子的陽轉子其齒數少，齒相對較厚，剛度好，具有較小的熱變形及彎曲變形，強度也較高， 不易損壞；齒的型線無尖點，齒面光順連接，便于加工與檢測，振動小，噪音低，轉子齒高 半徑和齒頂高合理，面積利用系數大；在工作時輸氣量大，效率高。

具體實施方式

如圖1所示， 一種螺桿式壓縮機轉子，包括有陰轉子及陽轉子，陰轉子上設有7個陰轉 子齒，陽轉子上設有5個陽轉子齒，陰轉子齒與陽轉子齒互相嚙合，各陰轉子齒、陽轉于齒 的外輪廓型線分別由以下各離散點依次連接而成

其中，各離散點的坐標原點為陰轉子的中心，以上各離散點的值為理論值，在制造加工 時，考慮制造成本及精度要求為其預留一定的公差范圍。本實施例相對于現有的螺桿式壓縮機轉子來說，由于轉子采用不對稱結構，作為主動轉 子的陽轉子其齒數少，齒相對較厚，剛度好，具有較小的熱變形及彎曲變形，強度也較高， 不易損壞；齒的型線無尖點，齒面光順連接，便于加工與檢測，振動小，噪音低，轉子齒高 半徑和齒頂高合理，面積利用系數大；在工作時輸氣量大，效率高。
