一、前言 近代精密齿轮的加工方法,种类很多,尤以插齿、剃齿应用较为广泛。但对于小模数齿轮(m≤0.5)的加工,这些方法不免要受到限制,因其使用的刀具磨制较困难,砂轮磨耗亦很快。 因滚刀本身是一蜗杆,所以在螺丝磨床上加工滚刀时,砂轮的磨耗均匀且较少。又因滚刀是直线齿形,检 First, the foreword The modern precision gear processing methods, many types, especially gear teeth, shaving teeth more widely used. However, for the small modulus gear (m ≤ 0.5) of the processing, these methods inevitably have to be limited, because the use of the tool grinding more difficult, grinding wheel wear quickly. Because the hob itself is a worm, so grind hob in the screw grinder, the grinding wheel wear uniform and less. Because the hob is a straight tooth, seized
