摘要
为了提高压力机齿轮啮合能力,开展面向齿面剥落的斜齿轮啮合刚度研究。构建斜齿轮副的接触线模型,综合考虑切片算法和积分过程,计算斜齿轮副运行状态下的啮合刚度。研究结果表明:增加四边形剥落的故障长度、啮合位置呈现持续增大,啮合刚度降低。轴向剥落区域差异引起啮合刚度降低,剥落区域啮入点与啮出点出现较大变化。圆形与三角形状态对应的啮合刚度呈现非线性特征下降趋势,四边形剥落条件下啮合刚度的线性下降,剥落区对应的啮合位置也存在较大差异。
In order to improve the meshing ability of press gear,the meshing stiffness of helical gear facing the tooth surface spalling was studied.The contact line model of helical gear pair was constructed,and the meshing stiffness of helical gear pair was calculated considering slicing algorithm and integral process.The results show that the meshing position increases continuously and the meshing stiffness decreases when the fault length of quadrilateral spalling is increased.The difference of axial spalling area results in low meshing stiffness and great changes in the entry and exit points of the spalling area.The meshing stiffness corresponding to the circular and triangular state assumes a nonlinear decline trend,and the meshing stiffness in the quadrilateral spalling condition decreases linearly,and the corresponding meshing position in the spalling area also differs significantly.
