广泛使用的剃齿工艺存在着一个关键问题,剃后齿形中凹。它影响齿轮接触精度和噪声特性,对提高产品质量不利,阻碍了这项工艺的使用前景。两年来,我厂采用靠模法对剃齿刀进行修形后剃齿,克服了中凹,提高了接触精度,使齿轮噪声平均降低了5dB,音质柔和。剃齿刀修形量是根据标准剃刀剃齿后,产生齿形误差的数值和分布形状来确定的。再根据修形量来设计专用靠模板使砂轮成形,修磨剃齿刀,靠模
A key problem with the widely used shaving process is that the shave has a concave profile. It affects the gear contact accuracy and noise characteristics, to improve product quality adversely hinder the use of the process. Over the past two years, I plant by shaving method to shave the shaving cutter after shaving, to overcome the concave, improve the contact accuracy, the average gear noise is reduced by 5dB, soft sound quality. Deformation of shaving knives is determined based on the numerical value and shape of the toothed errors resulting from the shaving of a standard razor. According to the amount of repair to design a special template to wheel forming, grinding shaving knives, by the mold
