以往，我公司所产的振动压路机上的中模数齿轮采用250kHz电流感应加热淬火工艺，由于Xi艺存在硬化层分布不合理的缺陷，造成齿轮质量不稳定、使用寿命短，直接影响产品质量。为此，我们改为在超音频设备上进行中模数齿轮淬火。1．淬火方法门）设备选用根据实际情况，我们选用两 In the past, my company produced the vibratory roller on the modulus gear with 250kHz current induction hardening process, due to the presence of hardened Xi layer has an unreasonable distribution of defects, resulting in gear quality is unstable, short life, a direct impact on product quality. To this end, we are in the super audio equipment in the modulus gear quenching. 1. Quenching method door) Equipment selection According to the actual situation, we use two
