本文针对NGW型行星减速器派生系列设计中若干参数进行了优选的探讨,其中包括按提高齿面接触强度选择外啮合的变位参数α_Ⅰ′;按等滑动率分配外啮合变位系数x_Ⅰ∑;按内啮合节点位于双齿啮合区确定内啮合传动的变位参数α_Ⅱ′;按接触和弯曲等强度原则对内、外啮合的组合寻求最佳m/a比值(0.028～0.045),依此经过分析研究,建立数学模型,经“电算”证实:得到不仅外啮合接触强度高,而且内啮合的重合度也高。最后将其拟合成数学表达式,以供设计者参考使用。
In this paper, some parameters in the design of derivative series of NGW planetary gear reducer were studied in detail, including the selection of the external gear displacement parameter α_Ⅰ ’by increasing the contact strength of the tooth surface, the external gear shift coefficient x_ⅠΣ at equal slip rate, According to the principle of contact and bending, the best m / a ratio (0.028 ~ 0.045) is sought for the combination of internal and external meshing, according to which the internal meshing node Analytical research, the establishment of mathematical models, the “computer operator” confirmed: get not only the outer contact high contact strength, but also the high degree of coincidence of the internal gear. Finally, it is fit into a mathematical expression, for the designer’s reference.
