37SiMn2MoV调质齿轮弯曲疲劳可靠性试验

Test Research on Reliability of Gear-tooth Bending Fatique Strength for Through Hardening Steel 37SiMn2MoV

摘要: 论述37SiMn2MoV调质齿轮轮齿弯曲疲劳强度的可靠性试验研究,该试验是在英国制造的EMR-1603型电磁谐振疲劳试验机上进行的,分4个应力级,每个应力级的试验样本不少于6个。在试验数据基础上,拟合出R-S-N曲线及方程,最后求得不同可靠度下37SiMn2MoV调质齿轮轮齿的弯曲疲劳强度极限。

Abstract: The experimental investigation on the reliability of gear-tooth fatigue strength for through hardening steel 37SiMn2MoV was tested. The tests were carried out on a electro-magnetic resonance fatique test machine of type EMR-1603 (U. K). Four loading sbtrss levels (of 6 samples each) were conducted. Based on the test data, the R-S-N curves and the related equations were fitted. Finally, the limiting bending fatique strength σ_Flim of the 37SiMn2MoV gear-tooth under different reliabilities have been evaluated.
