基于啮合理论的双导程ZN型蜗杆副精确建模
Exact solid-modeling of double pitch ZN-type worm gears based on meshing theory
摘要
Abstract
Exact solid-modeling of worm gears is very important for computer aided analysis,the model precision directly influences the accuracy of the subsequent CAE analysis.Aimed at the problem,a method for exact solid-modeling of double pitch ZN-type worm gears is presented based on meshing theory.Firstly,the paper analyzes the forming principle and characteristics of double pitch ZN-type worm gears and then deduces the mathematical equations of double pitch ZN-type worm gear;secondly,gear tooth working surface and boundary surfaces of worm gears are reconstructed by NURBS surface interpolation;finally,the three dimensional solid model of double pitch ZN-type worm gears is generated by trimming and stitching the surface.Error analysis shows that the geometric error of double pitch ZN-type worm gears established by this method is minimal,and it can meet the requirements of the subsequent CAE analysis,and proposes a new thought for the complex structure design of worm gears.关键词
