摘要

齿轮副啮合刚度的周期性变化是齿轮系统产生振动的主要内部激励,以直齿圆柱齿轮副外啮合模型为研究对象,考虑齿面接触特性对齿轮刚度的影响,建立齿轮副接触分析有限元模型,计算轮齿啮合刚度,讨论了齿轮在发生轴向偏载以及受到不同负载情况下,齿轮啮合刚度变化的情况。针对接触区域应力分布情况,探究啮合刚度的变化原因。讨论刚度变化原因和研究分析发现:在齿轮发生轴向偏载的情况下,随着轴向偏载的增大,齿轮啮合刚度逐渐减小。对啮合齿轮施加不同的负载时,随着负载的增大,齿轮啮合刚度呈线性趋势逐渐增大,增大到一定的情况后,啮合刚度趋于平缓。

Abstract

The periodic change of gear pair meshing stiffness is the main internal motivation of gear system vibration,taking the external meshing model of the straight tooth cylindrical gear pair as study object,considering the influence of tooth contact characteristic on the gear stiffness,the contact analysis of finite element model of the gear pair is established,the gear meshing stiffness is calculated,the change situation of gear meshing stiffness is discussed with gear in the case of the axial load and under different load cases. In view of the stress distribution of contact area,the changing reason of the meshing stiffness is researched. It is found that gear meshing stiffness decreased with the increase of axial load. When the meshing gear is subjected to variant loads,the stiffness increased in a linear pattern with the increase of load,and it tended to remain stable after reaching a certain degree.
