汽车齿轮在使用过程中，由于轴、轴承和齿轮箱在载荷传递下的变形，使齿轮的对中状态发生很大变化。在这样的条件下，要求齿轮不仅满足在最大载荷条件下的强度和耐久性的可靠性，而且满足在汽车巡航期间的轻载荷条件下的低振动特性。在这份报告中，齿轮的振动和承载能力方面的最佳齿面形状的特点是明确的。局部最优齿面形状出现在每个激励谷，在那里的振动激励是低的，实际重合度取一个特定的值。研究了不同局部最优解的选择对优化齿轮振动性能的影响。提出了从振动和承载能力两个方面考虑的齿轮组最佳齿面形状的实用设计算法，并根据现场经验对其结果进行了评价。
The alignment condition of automotive gears changes considerably during operation due to the deformation of shafts, bearings, and gear box by transmission of load. Under such conditions, the gears are required to satisfy not only reliability in strength and durability under maximum loading conditions, but also low vibrational characteristics under light loading conditions during the cruising of a car. In this report, the characteristics of the optimum tooth flank form of gears in terms of both vibration and load carrying capacity are clarified. The local optimum tooth flank form appears in each excitation valley, where the vibrational excitation is low and the actual contact ratio takes a specific value. The influence of the choice of different local optimum solutions on the vibrational performance of the optimized gears is investigated. The practical design algorithm for the optimum tooth flank form of a gear set in terms of both vibration and load carrying capacity is then proposed and its result is evaluated by field experience.
