專利名稱：一種大型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轉子，尤其涉及一種大型螺桿式壓縮機轉子。
背景技術：
螺桿式壓縮機有一對相互嚙合的按一定傳動比反向旋轉的螺旋形轉子，水平且 平行配置于機體內部，具有凸齒的轉子為陽轉子，通常為驅動轉子，具有凹齒的轉子稱 為陰轉子，通常為從動轉子。螺桿式壓縮機屬于容積式壓縮機，它利用一對相互嚙合的 陰陽轉子在機體內作回轉運動，周期性地改變轉子每對齒槽間的容積完成吸氣、壓縮、 排氣過程。螺桿式壓縮機轉子的齒形決定螺桿式壓縮機的性能。目前螺桿式壓縮機轉子的 齒形組成曲線有圓弧、擺線和橢圓及其包絡線等，但陰陽轉子的齒數比一般為6 5， 陰陽轉子的直徑差較大，陰轉子直徑較小，不適合陰轉子驅動陽轉子，且因轉速比為1.2 倍，對螺桿式壓縮機排氣量的提高有限；由圓弧、擺線及其包絡線組成的螺桿式壓縮機 轉子的齒形存在尖點棱角，不利于加工和檢測，噪聲較大。
發明內容本實用新型的目的在于克服上述現有技術的不足而提出一種易于加工，嚙合面 光滑，密封性好，陰陽轉子的直徑差小，可互換驅動轉子，振動小，噪聲低，提高螺桿 式壓縮機的排氣量和效率的螺桿式壓縮機轉子。本實用新型的目的可以通過如下措施來達到參見附圖，一種大型螺桿式壓縮 機轉子，它包含陰轉子1和陽轉子2，其特征在于陰轉子1和陽轉子2的齒形為雙邊非對 稱，齒形的組成曲線為圓弧和橢圓及其包絡線，陰陽轉子的齒數比為7 5，陰陽轉子的 直徑分別為248mm和262mm，陰陽轉子的中心距為206mm。本實用新型同現有技術相比可產生如下積極效果1.轉子的齒形組成曲線為圓弧和橢圓及其包絡線，接觸線短，泄漏三角形小， 嚙合平穩，密封性好，效率高；2.各組成齒形曲線間光滑連接，型線上無尖點，便于加工和檢測，流線性好， 噪聲低；3.節圓處成點嚙合，使整個嚙合線均可形成油膜；4.齒形為雙邊非對稱，陰陽轉子直徑調整方便，轉子間力矩分配合理，振動 小；5.陰陽轉子的齒數比為7 5，轉速比為1.4倍，陰陽轉子直徑相差不大，轉子 剛度接近，承載能力高，可用于壓差和壓比較大的工況，可實現陰轉子1驅動陽轉子2， 減少壓縮機的開發系列。我們知道，一種規格轉子的螺桿式壓縮機當R22制冷劑更換成R134a制冷劑 時，其制冷量和功率降低至0.7左右，也就是說，要制冷量不變，通常的技術是用大一個規格轉子的螺桿式壓縮機。而采用本實用新型的技術，陰陽轉子的齒數比為7 5，轉速 比為1.4倍，不用增大一個規格轉子，就用原規格轉子實現了制冷量不變，且因排氣量的 提高，容積效率將提高，壓縮機性能也就提高；對該規格轉子螺桿式壓縮機而言，因轉 子規格相同就可壓縮機的鑄件通用，因轉子齒形通用則加工齒形的刀具通用，從而可以 減少機型的開發和刀具的投入，可以大大節省開發成本，加快開發進度，使螺桿式壓縮 機有更廣的應用領域。
