剃齿是用来光整未经淬火的齿轮,可以获得2～1级或更高的精度(剃齿通常能使齿轮的精度比剃齿前提高一级);光洁度达。剃齿的生产率比磨齿高,而成本却比磨齿低,因此在大批和大量生产中几乎全以剃齿来代替磨齿了。但是在小批生产中,若配备一台剃齿机供剃齿是不可能的,同时也是不经济的。此外,因一般剃齿机有一定的使用范围,若碰到非正规形状的工件(如大小轮径相差较多的双联齿轮),有时无法加工,须改用其他机床代替。根据这些要求,现在介绍用万能臥式铣床或立式铣床进行剃齿,同样能保证精度,现将加工方法说明如下:
Shaving the teeth is used to smooth the unhardened gear, you can get 2 to 1 or more precision (shaving usually make the gear accuracy than shaving before the increase of one); finish up. The productivity of shaving teeth is higher than that of grinding teeth, and the cost is lower than that of grinding teeth, so shaving teeth are substituted for grinding teeth in mass and mass production. However, in a small batch, it is not possible at the same time to equip a shaving machine for shaving teeth, and it is not economical at the same time. In addition, due to the general use of shaving machine has a certain range, if the encounter non-standard shape of the workpiece (such as the size of the wheel diameter difference between more double gear), sometimes can not be processed, to be replaced by other machine instead. According to these requirements, now introduce universal horizontal milling machine or vertical milling machine for shaving, the same guarantee accuracy, the processing methods are described below:
