摘要:
在齿轮副传动过程中，常因加工误差、安装误差、受力变形引起齿轮副偏载。分析了直齿圆柱齿轮副、斜齿圆柱齿轮副的偏载产生机理及齿轮修形的局限性，提出应用新型弧齿圆柱齿轮，来提高齿轮副传动承载能力与抗偏载能力。基于弧齿圆柱齿轮独特的几何特征分析了弧齿圆柱齿轮抗偏载的原理，采用有限元分析方法分别对直齿、斜齿、弧齿圆柱齿轮副进行受力分析，结果显示弧齿圆柱齿轮可以明显改善齿轮副齿面受力状态，具有明显的抗偏载特性。
The processing errors, installation errors and deformation often lead to Gears partial load during gear pair transmission process. The paper analyzes generating mechanism of partial load and limitations of gear modification about the spur gear pair as well as the Helical Gear Pair, proposing to use this new arc cylindrical gear to improve the carrying capacity and anti-bias load capacity of the auxiliary drive gear. The paper analyzed the principle of anti-bias arc cylindrical gear carrier based on the geometric characteristics of the arc cylindrical gear, using the finite element method to analyze the stress of straight teeth, Helical and arc tooth cylindrical gear pairs respectively, showed that the arc cylindrical gear pairs can significantly improve the stress state of tooth surface, with a clear anti-side load characteristics.
