齿轮传动机构,随着机械产品更新的要求,向着高精度,低噪音、小体积、大功率和耐用的方向发展。因此,提高淬火后齿轮的精度,就要求有经济的、高效率的加工方法,以修正热处理(淬火)后齿形、齿向变形产生的误差。对于精度要求(JB179-60)7～6级的火后中硬齿面的加工,火后剃齿是比较实用的中硬齿面加工方法之一。所谓火后剃齿,即在批量生产中精切齿,留剃量,热处理后再进行剃齿。与火前剃齿相比,火后剃齿还应特别注意处理好下列工艺要求。
Gear transmission, with the requirements of mechanical products updated toward the high-precision, low noise, small size, high power and durability direction. Therefore, to improve the accuracy of the gear after quenching, requires an economical and efficient processing methods to correct the heat treatment (quenching) after the tooth-shaped, tooth-to-tooth deformation error. For the accuracy requirements (JB179-60) 7 to 6 after the fire in the hardened surface processing, after shaving fire is more practical in the hardened one of the methods. The so-called fire shaving, that is, in the mass production of fine teeth, leaving the amount of shaving, heat treatment and then shaving. Compared with pre-fire shaving, after-fire shaving should also pay special attention to handle the following process requirements.
