Furthermore, it gives the normal pressure ahead of the cutting zone which can be predicted from orthogonal cutting using the concept of effective rake angle. 更可用有效倾角概念利用直角切削资料来预测斜角切削的切削刃前的平均压力。
It's testified by using theory of limit value that the sum of modification coefficients xE is more than the separate coefficient of normal pitch circle y at modified gearing of working pressure angle. 运用极值理论详细论证了角变位齿轮传动变位系数之和xE恒大于分度圆分离系数y。
In the light of this, the criteria for choosing the values of the normal pressure angle and helical angle of the gear ale laid down, and the equation for calculating the contact stress is simplified with coefficients and the corresponding coefficient graphs are presented. 为此,制定了齿轮法向压力角和螺旋角取值标准,并将击面接触应力公式系数化,最后给出筒化后的接触应力计算公式和相应的系数图表。
