对非车制倒角的圆锥滚子来说,倒角的好坏直接影响成品滚子的质量,而在设计冲模时,冲模凹穴倒角圆弧半径R值多采用经验数据,常出现滚子倒角质量不稳定。本文推导出R值的计算公式,从而提高模具凹穴倒角圆弧半径的精度。 For non-car chamfering tapered roller, chamfer directly affect the quality of the finished roller, and in the design of die, the die cavity chamfer arc radius R value using empirical data, often appear to roll Chamfer quality is not stable. In this paper, the formula of R value is deduced to improve the accuracy of chamfering arc radius of die cavity.
