弧齿锥齿轮的数字标准齿轮研究

The Study on Numerical Standard Gear of Spiral Bevel Gear

模拟生成了多组不同的带误差齿面并分别进行了相应的仿真计算、图像处理和量化比较,分析了齿面误差沿齿高分布、沿齿向分布、综合分布等不同分布形式和大小对弧齿锥齿轮传动性能的影响;在给出一定载荷下齿面承载印痕的相对偏移范围和承载传动误差曲线幅值波动范围的前提下,经进一步分析,得到了实际齿面误差分布的合理范围——数字标准齿轮,使齿面误差分布落在该范围内的实际齿面在相应工况下能够满足所给出的动态印痕要求和承载传动误差的幅值波动限制要求。

Many groups of digital gear faces with error is simulated, and the influence of load - bearing properties is tudied if the error along the high, along the length and integrated. On the assumption that the evaluation criterion of gear bearing performances is the relative offset of the contact pattern and the fluctuation of transmission error under load, after further analysis, appropriate tooth surface error distribution scope - numerical standard gear is obtained, so that the gear will meet the dynamic demand of contact pattern and transmission error, in the same condition, if its＇ error distribution falls within the scope.
