The influence of main design parameters of hypoid gears with low shaft angle, namely, the offset, shaft angle, cutter radius, gear ratio, and the spiral angle of wheel, on the geometrical morphology the gear tooth surfaces has been investigated. Checks for obtaining appropriate top-land widths and spiral angles at the toe and heel sides have been developed and applied. The limits for the main design parameters that yield non-adequate tooth surfaces because- of top-land pointing, undercutting, or having a negative value of the spiral angle of wheel at the toe side have been investigated based on the results obtained by the simulation of a large number of cases of design. A specific computerized flow chart has been designed to iterate among the main design parameters to obtain a qualified region for them. With those results, a limiting graph has been proposed to get the list of recommended values of main design parameters and provide a reference for their selection. Finally, the results of loaded tooth contact analysis of two cases of design arbitrarily chosen from the proposed limiting graph of recommended values are shown to verify its applicability to yield to successful designs with favorable conditions of meshing and contact.

研究了低轴角准双曲面齿轮的主要设计参数，即偏心距，轴角，刀具半径，齿轮比和车轮的螺旋角，对齿轮齿面的几何形态的影响。已经开发并应用了检查以在脚趾和脚跟侧获得合适的顶地宽度和螺旋角。根据模拟获得的结果，研究了由于顶面指向，侧切或在脚趾侧具有车轮的螺旋角的负值而导致齿面不足的主要设计参数的限制大量的设计案例。已设计出一种特定的计算机流程图，以在主要设计参数之间进行迭代以获得一个合格的区域。有了这些结果，已经提出了一个极限图来获取主要设计参数的推荐值列表，并为它们的选择提供参考。最后，显示了从建议的建议极限值图表中任意选择的两种设计情况的载荷齿接触分析结果，以证明其适用于屈服和接触条件良好的成功设计。
