【摘要】：基于Smith切片法理论,提出了一种快速计算斜齿轮副传递误差和啮合刚度的改进方法。该模型将斜齿轮沿齿宽方向划分为一系列相互独立的薄直齿轮,考虑单个切片的弯曲-剪切变形、局部接触变形及轮体结构变形,通过各切片间的变形协调关系建立斜齿轮非线性承载接触模型,进而得到齿面载荷分布、传递误差和啮合刚度等信息。该方法较Smith切片法增加了时变单齿刚度、接触变形非线性效应以及轮体结构参数的影响,提高了模型的计算精度和适用性。该模型的计算精度与有限元方法相当,但具有更高的计算效率,更适合于齿轮传动系统振动和噪声的快速预测。
[Abstract]:Based on the theory of Smith slicing, an improved method for fast calculating the transfer error and meshing stiffness of helical gear pair is proposed. In this model, helical gears are divided into a series of independent thin spur gears along the width of the tooth. The bending shear deformation, local contact deformation and wheel structure deformation of a single slice are considered. The nonlinear load bearing contact model of helical gear is established by the deformation coordination relationship among sections, and then the information of tooth surface load distribution, transmission error and meshing stiffness are obtained. Compared with Smith slice method, this method increases the time-varying single-tooth stiffness, the nonlinear effect of contact deformation and the influence of wheel structure parameters, and improves the accuracy and applicability of the model. The accuracy of the model is similar to that of the finite element method, but it has higher computational efficiency and is more suitable for rapid prediction of vibration and noise of gear transmission system.
