摘要/Abstract

摘要： 传统的螺杆转子成形砂轮设计研究主要集中在成形砂轮廓形精度提升方面,成形砂轮的切削加工性能与成形砂轮安装参数之间的耦合关系没有得到足够的关注,导致设计出来的螺杆转子成形砂轮切削加工性能不高,从而致使螺杆转子的成形磨削表面质量差、加工效率低。本文提出了一种新的基于切削加工性能的螺杆转子成形砂轮安装参数二次优化设计方法。首先,基于空间啮合原理设计螺杆转子成形砂轮安装参数优化设计程序,获得不干涉条件下的螺杆转子成形砂轮安装参数范围;其次,对不同安装参数下成形砂轮与螺杆型面的接触特性,以及不同安装参数条件下成形砂轮的轮廓特性、切削加工特性进行系统的分析和研究,获得了螺杆转子成形砂轮安装参数选择策略。以某型号三螺杆泵阳转子为例对该方法进行验证,结果表明,在保证加工质量的前提下,该方法可以显著降低螺杆转子精密磨削成本,具有较好的理论创新性与工程应用价值。

Abstract: Traditional research on the screw rotor forming grinding wheel mainly focuses on improving the profile accuracy of the forming grinding wheel.The coupling relationship between the cutting performance of the forming grinding wheel and the installation parameters of the forming grinding wheel has not received enough attention,leading to the unsatisfying cutting performance of the designed screw rotor forming grinding wheel,further deteriorating the surface quality and machining efficiency of the screw rotor.A novel secondary optimization design method for the installation parameters of the screw rotor forming grinding wheel was proposed based on the cutting performance.In this method,an optimization design program was designed to obtain the parameters range of the screw rotor forming wheel installation without interference based on the spatial meshing principle.The contact characteristics of the forming grinding wheel and the screw profile under different installation parameters,as well as the profile characteristics and cutting characteristics of the forming grinding wheel under different installation parameters were systematically analyzed,obtaining the installation parameter selection strategy of the screw rotor forming grinding wheel.The method was validated with a male rotor of three-screw pump as an example.The results demonstrated that the proposed method could significantly reduce the precision grinding cost of screw rotor as well as guaranteeing the grinding quality,and had good theoretical innovation and engineering application value.
