35CrNiMo感应淬火齿轮接触疲劳强度试验

Experimental Study on Contact Fatigue Strength of Induction Hardened Gears of 35CrNiMo

限于大模数齿条新材料35Cr Ni Mo弯曲接触疲劳基础数据的空白,采用成组与爬山试验方法,获得了三峡升船机大模数齿条新材料35Cr Ni Mo感应淬火齿轮接触疲劳极限,基于labview软件的数据处理方法,得到了齿轮的疲劳极限应力、接触疲劳寿命分布和不同可靠度下的R-S-N曲线族,为该材料齿轮齿条可靠性设计提供了基础数据。

This paper discusses the experiment of the contact fatigue strength of 35 Cr Ni Mo induction hardened gear and Labview-based data processing. Obtained the fatigue limit stress of gear、distribution of the life of contact fatigue and the P-S-N curve family of different reliability. Provided reference data based on experiment for reliability design materials gear strength.
