矿用减速器齿轮根切半径的求法

Method of Calculating Root Cut Radius of Gear for Mine Reducer

在德国进口的煤矿机械用减速器中,大量使用着根切齿轮,并且齿轮的齿根弯曲疲劳强度和使用寿命不会因此而过度降低,也就是说存在一个最佳的根切量以及对应的最佳变位系数,要确定最佳变位系数,首先得计算齿轮根切半径。

In the reduction gear used in the coal mine machinery imported from Germany,extensive use of root cutting gear,and the gear root bending fatigue strength and service life will not be excessively reduced,that is to say,there exists an optimal root cut and corresponding optimal displacement coefficient.To determine the optimal displacement coefficient,first,the cutting radius of the gear root must be calculated.
