摘要
分析了三种实际应用较为广泛的,分别带有阿基米德线、渐开线、余摆线的螺杆真空泵螺杆转子型线,具体比较了三种型线组成曲线啮合特性和型线的优劣。详细阐述了螺杆的车削加工方法,分别建立了带有刀位点的三种螺杆车削加工模型,并且给出了车削刀具的选取依据。最后,简单地介绍了一种高效的螺杆铣削螺杆加工方法,并提供了一种实用的螺杆加工精度测量方法。
In this paper, the screw rotor profile of three widely used screw vacuum pumps were analyzed, including the ones with Archimedes , involutes and trochoid , and the advantages and disadvantages of their meshing characteristic as well as their profile were compared. Then it elaborates the turning methods for screw machining, establishes the machining model for three kinds of screw turning with cutter location point, and gives the basis for the selection of cutting tools. Finally, an efficient milling method for screw machining is introduced, and a practical precise measuring method is recommended for screw machining.
