齿数z_1<25牙的少齿数齿轮,径剃齿后出现齿形中凹,是齿轮加工行业一个长期得不到解决的重要课题。齿轮齿形中凹是造成传动的高噪声和低寿命的重要原因。为了解决这种中凹现象,一个常用的方法是对剃齿刀齿面作反修形。即在剃齿刀齿面的对应中部修磨成内凹形式。但是这种修形方法十分困难,因为它的位置和修形量都需要进行反复试磨和试剃才能成功。最近,小啮合角剃齿刀,已被成功地应用在少齿数齿轮的剃削加工。它比反修形方法
Number of teeth z_1 <25 Number of teeth less gear teeth after gear shaving dentate, gear processing industry is a long-term unresolved an important issue. Gear teeth in the concave is caused by transmission of high noise and low life important reason. In order to solve this concave phenomenon, a common method is to reverse shaving the tooth surface. That is, in the middle of the tooth shaving face corresponding sharpened into a concave form. However, this modification method is very difficult, because its position and shape modification requires repeated trial grinding and try to shave to be successful. Recently, small-angle gear shaving knives have been successfully applied to shaving with fewer teeth. It is more than anti-modified method
