摘要:
螺杆转子的形状精度直接影响螺杆压缩机的性能。为分析成形磨削加工螺杆转子的廓形误差,该文基于砂轮-转子间的坐标变换及啮合原理,以转子整体廓形误差为评价指标,提出了一种螺杆转子廓形误差分析方法。通过调整砂轮的安装参数,分析了人工扰动下成形磨削螺杆转子的实际廓形,得到砂轮各安装误差对螺杆转子廓形精度的影响规律及程度。结果表明,砂轮安装角误差和砂轮与转子中心距的误差导致转子廓形缩放,砂轮轴向位置误差导致转子廓形自转,且砂轮安装参数对阳转子廓形的影响大于对阴转子廓形的影响。
Abstract:
The profile accuracy of the screw rotor affects the performance of the screw compressor.To analyze the profile error of the screw rotor under form grinding,the overall rotor profile error is taken as the evaluation index,the engagement theory and the coordinate transformation between the grinding wheel and the screw rotor are considered,and then an error analysis on the screw rotor profile is proposed.To study the installation error impact on the accuracy of the screw rotor profile,the installation parameters of the grinding wheel are adjusted,and the real profile of the screw rotor under artificial disturbance is analyzed.The results show that the installation angle error of the grinding wheel and the center distance error between the grinding wheel and the rotor result in the the rotor profile variation.The axial position error of the grinding wheel also results in the rotor profile rotation.The grinding wheel installation parameters have more influence on the male rotor profile than on the female one.
