摘　　要：对准双曲面齿轮副进行不同载荷下的承载接触分析(loaded tooth contact analysis,LTCA),获得等效啮合力、承载传动误差、综合弹性变形、时变啮合刚度及实际重合度等参数。对比了LTCA与加载接触试验得到的齿面啮合印痕,分析了载荷大小对啮合参数的影响。结果表明,载荷变化对啮合力、传动误差、啮合刚度及重合度等参数的影响显著,传动误差及啮合刚度曲线随载荷增大呈显著非对称特征。载荷较低时,实际重合度随载荷增加上升明显,载荷达到一定幅值后其变化趋于平缓。获得的时变啮合参数能够准确反映准双曲面齿轮副不同载荷下的啮合特征,为准双曲面齿轮系统不同工况下的动态啮合特性及动力学行为分析提供了支持。Loaded tooth contact analysis of a hypoid gear drive under different loads was implemented.The loaded transmission error,equivalent meshing force,comprehensive elastic deformation,time-varying meshing stiffness and actual contact ratio were obtained.The contact patterns obtained by LTCA were compared with those obtained by a loaded rolling test.The influence of the load amplitude on the meshing parameters was analyzed.Results show that the effects of the variation of the load on the meshing force,transmission error(TE),meshing stiffness and contact ratio are significant.The TE curve and meshing stiffness curve show obvious asymmetric characteristics with the increase of the load.Under low load,the actual contact ratio increases significantly with the increase of the load,while the change tends to be flat after the load reached a certain amplitude.The obtained time-varying meshing parameters can accurately reflect the meshing features of the hypoid gear drive on different loads,and provide a support for analyzing the dynamic meshing characteristics and dynamics behavior of the hypoid gear system.
