齿轮齿根过渡曲线处圆角的大小,对齿轮强度有重要影响,而这圆角大小是与铣齿刀盘刀刃圆角有直接关系的。齿根过渡部分的圆角大,不仅有利于齿轮强度,而且由于大的刀刃圆角半径使刀具的使用寿命提高。为此,希望使用尽可能大的刀刃圆半径,以便取得理想的齿轮寿命和经济效果。但是,一般齿轮刀具设计时不进行刀刃圆角半径计算,而仅凭经验数据选 Gear tooth root transition curve at the corner of the size of the gear strength has a significant impact, which is the size of the fillet with the milling cutter cutter blade fillet has a direct relationship. Tooth root transition part of the fillet, not only in favor of gear strength, but also because of the large blade fillet radius of the tool life. For this reason, it is desirable to use as large a radius as possible in order to achieve the desired gear life and economy. However, the general gear cutter design does not calculate the radius of the fillet, and only empirical data selection
