基于修形插齿刀具的非圆柱齿轮齿廓修形方法
摘要
Abstract
Non-cylindrical gear is a special kind of gear for variable gear ratio transmission. As with the meshing transmission of cylindrical gear, non-cylindrical gear is also subject to meshing impact during gear meshing, and meshing impact is more obvious because non-cylindrical gear's meshing radius and pressure angle change greatly. However, considering tooth profile curve of non-cylindrical gear cannot be accurately expressed with equation, its tooth profile cannot be directly modified. The paper presents two shaper cutters respectively for variable-polar radius profile modification and variable-polar angle profile modification, and obtains the non-cylindrical gear after profile modification with linear increasing variable-polar angle profile modification shaper cutter. Finite element simulation results indicate that transmission performances of the modified non-cylindrical gear such as bending stress and contact stress are better.关键词
