【摘要】：基于Smith切片法理論,提出了一種快速計算斜齒輪副傳遞誤差和嚙合剛度的改進(jìn)方法。該模型將斜齒輪沿齒寬方向劃分為一系列相互獨立的薄直齒輪,考慮單個切片的彎曲-剪切變形、局部接觸變形及輪體結(jié)構(gòu)變形,通過各切片間的變形協(xié)調(diào)關(guān)系建立斜齒輪非線性承載接觸模型,進(jìn)而得到齒面載荷分布、傳遞誤差和嚙合剛度等信息。該方法較Smith切片法增加了時變單齒剛度、接觸變形非線性效應(yīng)以及輪體結(jié)構(gòu)參數(shù)的影響,提高了模型的計算精度和適用性。該模型的計算精度與有限元方法相當(dāng),但具有更高的計算效率,更適合于齒輪傳動系統(tǒng)振動和噪聲的快速預(yù)測。
[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.
