影响鼓形齿联轴器力学性能的参数研究

Research of the Influence Parameter of Crown Gear Coupling Mechanical Property

利用有限元分析软件ANSYS建立了鼓形齿联轴器三维实体模型,系统地研究了两轴线平行工况下压力角A、齿顶高系数ha*以及刀具位移圆半径R三个参数的变化对鼓形齿联轴器承载性能的影响。研究结果表明,在两轴线平行工况下,随着位移圆半径和齿顶高系数的增大,鼓形齿联轴器的承载性能会相应增强,但压力角的变化对鼓形齿联轴器的承载性能影响不大。

The crown gear coupling three - dimensional entity model is established by using finite element analy- sis software - ANSYS. At the working condition that the two axis are parallel, the influence of crown gear coupling bearing performance is studied when the pressure angle, addendum coefficient or tool displacement circle radius is changed. The results of the study show that at the working condition that the two axes are parallel, the bearing perfor- mance of the crown gear coupling is corresponding enhancement along with the displacement circle radius and adden- dum coefficient increases. But the bearing performance of the crown gear coupling remains stable when the pressure angle is changed.
