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。
Three kinds of screw rotor screw lines with screw-type vacuum pumps, Archimedes line, involute and trochanter respectively, which are widely used in practice are analyzed. inferior. The turning machining method of the screw is elaborated in detail, and the three screw turning machining models with the cutter point are respectively established, and the basis of selecting the turning tool is given. Finally, a brief introduction of an efficient screw milling method of screw milling, and provides a practical measuring method of screw precision.
