一、序言在高负荷条件下,需要有不发生折损、齿面耐点蚀、耐磨耗、耐烧伤的齿轮。因为齿轮负荷多受齿面接触强度的限制,所以最近通过齿面硬化来增加齿面硬度,提高接触压力的方法被广泛应用。齿面硬化法,虽有渗碳淬火、高频淬 First, the preamble Under high load conditions, there is no need for damage, tooth surface pitted, wear-resistant, burn-resistant gear. Because the gear load is greatly limited by the contact strength of the tooth flank, the method of increasing the flank hardness and increasing the contact pressure recently by tooth flank hardening is widely used. Tooth surface hardening method, though carburizing and quenching, high frequency quenching
