Screw air compressors have been being used widely for 45 years. There are many research works on these machines, but there have been still many problems, especially on designing and machining their screw pair, to study. This paper focuses on gate screw profiling from the main screw profile and disc tool profiling for manufacturing the screw pair. The air compressor screw 3D model pair, designed by using the proposed methods, have satisfied the meshing condition. The disc tool 3D models created for machining the screws have also been tested in many ways, these testing results show high accuracy of the disk tool 3D model, which can be used in industrial manufacturing.

空压机螺杆副的设计加工新方法

螺杆式空气压缩机已广泛使用 45 年。这些机器有很多研究工作，但仍有许多问题需要研究，特别是在设计和加工它们的螺杆副方面。本文主要从主螺杆轮廓和圆盘工具轮廓来研究用于制造螺钉副的浇口螺钉轮廓。采用该方法设计的空压机螺杆3D模型对满足啮合条件。为加工螺钉而创建的圆盘刀具3D模型也经过了多方面的测试，这些测试结果表明圆盘刀具3D模型的精度很高，可用于工业制造。
