Test Research on the Reliability of Gear-tooth Bending Fatigue Strength for Through Hardening Steel 35CrMo
-
摘要: 論述35CrMo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1603型電磁諧振疲勞試驗機上進行的的,分4個應力級,每個應力緩的試驗樣本不少于7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35CrMo調質齒輪輪齒的彎曲疲勞強度極限,Abstract: Deals with the experimental investigation on the reliability of gear-tooth fatigue for through hardening steel 35CrMo. The tests were canied out on a electro-mag-netic resonance fatigue test machine of type 1603 (U. K). Four loading stress levels (7 sample for each test) were conducted. Based on the test data, a R-S-N curve and related equation were fitted. Finally, the limiting bending fatigue strengh of the 35CrMo gear-tooth under different reliability have been evaluated.
