通常的修正齿轮计算复杂,往往使初学者望而生畏,不但耗时较多,而且由于计算繁琐,还容易发生计算差错。通过多年齿轮测绘工作,觉得有许多计算内容和公式可以略去。我们应用的计算方法,是按齿轮滚切时滚刀切入量与公法线长度变化量的关系来进行的。公制齿轮20°压力角的关系式如下: 公法线长度(毫米)/滚刀切入量(毫米)=1/1.46=0.6849315/1=0.6849315 (英制齿轮公式:1/1.997=0.5007511/1) 计算实例如下: 例一、一对啮合的大小齿轮副磨损后需要换新,但苦于找不到毛坯,需
The usual correction gear calculation complex, often daunting for beginners, not only time-consuming, but also because of the calculation is complicated, but also prone to calculation error. Through many years of gear mapping work, I think there are many calculations and formulas can be omitted. The calculation method we applied is based on the relationship between the amount of cutting of the hob and the change of the length of the common normal according to the gear hobbing. The relationship of metric gear 20 ° pressure angle is as follows: Common normal length (mm) / hob cut amount (mm) = 1 / 1.46 = 0.6849315 / 1 = 0.6849315 (Inch gear formula: 1 / 1.997 = 0.5007511 / 1) Calculation example As follows: Example 1, a pair of meshing gear wear after wear, need to renew, but suffer from can not find the rough, need
