Abstract

To enhance the bearing capacity and minimize the loaded transmission error for unparallel beveloid gears, a continuous optimization method of micro geometry is proposed. Considering that the conjugate characteristic of tooth surfaces is destroyed by misalignments and modification, an unload contact analysis model is first developed. This includes a contact tooth sequence determination model and an unloaded transmission error calculation model for multi-tooth contact. To determine contact due to deformation, a potential contact point matching model of non-contact tooth surfaces is introduced. Further, a numerical loaded contact analysis model based on the influence coefficient method for unparallel beveloid gear is developed. For multi-tooth contact of modified tooth surfaces, the transmission error compatibility condition is introduced. Based on the loaded contact model, a continuous optimization model for the comprehensive performance of contact pressures and loaded transmission error within a meshing cycle is established. To improve optimization efficiency, a calculation strategy for continuous optimization is developed. The feasibility of the proposed method is validated using a numerical example.

非平行双曲面齿轮微观几何的连续优化方法
为了提高非平行齿面齿轮的承载能力并最大限度地减小载荷传动误差,提出了一种微观几何连续优化方法。考虑到齿面的共轭特性会因错位和改动而遭到破坏,首先开发了一种非负载接触分析模型。这包括一个接触齿序确定模型和一个多齿接触的无负荷传动误差计算模型。为了确定变形引起的接触,引入了非接触齿面的潜在接触点匹配模型。此外,还开发了基于影响系数法的非平行齿面齿轮加载接触数值分析模型。对于修正齿面的多齿接触,引入了传动误差兼容条件。基于加载接触模型,建立了啮合周期内接触压力和加载传动误差综合性能的连续优化模型。为了提高优化效率,还开发了连续优化的计算策略。通过一个数值实例验证了所提方法的可行性。
