编辑同志: 读贵刊1978年第5期上刊登的何宗川同志的“端齿盘加工斜角β的作用与计算”一文(简称原文),很受启发。我们在实践中对斜角β有另一种计算方法,现提出来供参考。 此法基于这样一种想法,即对直齿盘来说,要使上下齿盘正确啮合,齿的锥顶必在齿盘中心线上。不但在轴向视图中齿形以定位中心为圆心呈幅射分布,而且在横剖面上(见图)β角之角顶必位于齿盘中心线上。这样我们就可较方便地进行计算了。

Editor comrades: read your issue published in 1978 on the 5th issue of Comrade He Zongchuan “Toothed Bevel gear processing β role and calculation,” a text (referred to as the original), very inspired. In practice, we have another method for calculating the bevel angle β, which is presented for reference. This method is based on the idea that for a spur gear, the top of the gear must be on the center line of the gear in order to properly engage the upper and lower spur gear. Not only in the axial view of the tooth profile centering on the center of the radial distribution, but also in the cross-section (see Figure) angle β angle must be located in the center line on the gear. So we can calculate more conveniently.
