剃齿已成为一种低成本、高效率的齿轮精加工方法,并被广泛地应用于成批、大量生产中,剃齿的加工精度可达6～7级。如选用的工艺合理,其效果不低于磨齿,还能降低齿轮传动的噪音。剃齿工艺存在的最大问题是产生齿形中凹误差,但可通过一些方法加以消除或减小至允许范围内(见本文二节)。此外,如果保证一定的剃前精度(如:齿圈径向跳动为6级精度,周节累积误差接近5级精度,齿形误差6级精度),并且在剃齿时尽可能提高齿轮的装夹定位精度,则可能剃出5级精度的齿轮。
Gear shaving has become a cost-effective and efficient method of gear finishing, and is widely used in mass production in large quantities, with gear shaving accuracy of 6-7. Such as the choice of technology is reasonable, the effect is not less than grinding teeth, but also reduce the noise of gear transmission. The biggest problem with the shaving process is that there is a toothed dent error that can be eliminated or reduced in some ways (see section 2 of this article). In addition, if you ensure a certain pre-shave precision (such as: ring gear radial runout accuracy of 6, the cumulative error of the week close to 5-precision, 6 error gear accuracy), and in gear shaving as much as possible to improve the gear installed Clip positioning accuracy, it may be shaved five-level precision gear.
