摘　　要：船式耕作机变速器传动系统在实际工作中传动轴和齿轮存在受力变形,导致齿轮副存在较大的啮合误差和严重的偏载。基于齿轮齿向修形方法,利用Romax软件对齿轮螺旋角修形参数和鼓形修形参数分别进行仿真分析与优化,确定出最佳修形方案。结果表明,齿轮齿向修形后大幅降低了齿轮接触应力,避免了齿轮齿面的应力集中,提高了船式耕作机变速器传动系统的承载能力和稳定性。Considering the actual deformation of the transmission shaft and gear of the transmission system of the ship tillage machine in actual work,the gear pair has a large meshing error and a serious eccentric load problem.Based on the gear tooth shape modification theory,Romax software was used to simulate and analyze the gear's helical angle modification and drum modification respectively to determine the best modification plan.The results show that after the tooth face is modified,the contact stress of the gear is greatly reduced,the stress concentration on the tooth face of the gear is avoided,and the load carrying capacity and transmission performance of the key gear pair of the transmission are improved.
