Abstract: The topology of parallel axis gears, such as spur and helical gears is modified to produce quieter and more smoothly operating gear sets with more uniform load distribution. A finite element analysis of the gear in its operating mode is made to produce a plot of radial and tangential deflections of the pinion and gear tooth surfaces which will occur when the gears are loaded during operation. The resultant plot is then inverted to produce a plot, or set of coordinates, which will define the path of travel of the gear tooth grinding wheel, which path is a mirror image of the plot of the finite element analysis. The resulting gears, when subjected to operating loads, will thus be deflected tangentially and radially to their optimum operating, or theoretical true involute, positions so as to produce quieter, smoother, and more evenly loaded gear trains.

Abstract translation: 平行轴齿轮（如直齿轮和斜齿轮）的拓扑结构被修改，以产生更均匀，更均匀的负载分布更加平稳的齿轮组。 在其操作模式下进行齿轮的有限元分析，以产生在操作期间装载齿轮时将发生的小齿轮和齿轮齿面的径向和切向偏转的曲线。 然后将所得到的图反转以产生绘图或坐标系，其将限定齿轮齿轮的行进路径，该路径是有限元分析图的镜像。 所产生的齿轮在经受操作载荷时将因此被切向地和径向地偏转到其最佳操作或理论真实的渐开线位置，以便产生更安静，更平滑和更均匀地装载的齿轮系。
