37SiMn2MoV調質齒輪彎曲疲勞可靠性試驗

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

摘要: 論述37SiMn2MoV調質齒輪輪齒彎曲疲勞強度的可靠性試驗研究,該試驗是在英國制造的EMR-1603型電磁諧振疲勞試驗機上進行的,分4個應力級,每個應力級的試驗樣本不少于6個。在試驗數據基礎上,擬合出R-S-N曲線及方程,最后求得不同可靠度下37SiMn2MoV調質齒輪輪齒的彎曲疲勞強度極限。

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.
