准双曲面齿轮几何结构参数设计研究

Research on Geometrical Structure Parameter Design of Hypoid Gears

介绍了一种准双曲面齿轮几何结构参数设计方法,即在不考虑顶隙的情况下,小齿轮的顶锥与大齿轮的根锥相切,小齿轮的根锥与大齿轮的顶锥相切,应用准双曲面齿轮副的节锥几何关系来确定小齿轮的顶锥角、根锥角、顶锥顶点和根锥顶点到齿轮副轴线交错点的距离等几何结构参数,并推导和提供了相应的几何结构参数设计计算公式,最后,给出了一个计算实例说明这种方法。

A method for the geometrical structure parameter design of hypoid gears is introduced. Under the condition of no consideration of the bottom clearance, the pinion tip cone is tangent to the wheel root cone and the pinion root cone is tangent to the wheel tip cone. By means of the pitch cone geometrical relationship of a pair of hypoid gears, the geometrical structure parameters can be determined, such as root angle and tip angle of the pinion, the distances between the cross point of the gear pair axes and the apexes of the tip cone and the root cone of the pinion. The corresponding formulae for the geometrical structure parameter design are presented. And lastly a numerical example is given for demonstrating this method.
