Gear contact fatigue has becoming a bottleneck restricting the safety and reliability of wind turbine transmission systems. Tooth interior fatigue fracture (TIFF) failure is commonly observed in case-hardened wind turbine gears. In this work, a contact fatigue model is developed to investi...
Tooth Interior Fatigue Fracture&Robustness of Gears 来自 urn.kb.se 喜欢 0 阅读量: 48 作者: M Mackaldener 摘要: The demands the automotive gear designer has to considerduring the gear design process have changed. To design a gearthat will not fail is still a challenging task, but now ...
Furthermore, the crack initiation of the tooth root breakage happens mostly at or just below the surface and not in greater material depth like the initial crack of the tooth flank fracture. The failure type of tooth interior fatigue fracture is most common on gears with alternating loads, ...
1)tooth root fatigue齿根疲劳 1.Helical and spur gears were used in the study where the densification as well as the resulting gear quality andtooth root fatiguewas tested.在研究中所用的螺旋齿轮与正齿轮,对致密化及所得到的齿轮的质量与齿根疲劳都进行了试验。
Define tooth root. tooth root synonyms, tooth root pronunciation, tooth root translation, English dictionary definition of tooth root. Noun 1. tooth root - the part of a tooth that is embedded in the jaw and serves as support root anatomical structure, b
A several kinds of numerical models, including moving force model, for determination the service life of gears in regard to bending fatigue in a gear tooth root, is presented. Finite element method and linear elastic fracture mechanics theories are then used for the further simulation of the fati...
aOn the fracture surface of the teeth, the crack initiation region and beach marks could be seen clearly with naked eye. It was observed that the fatigue crack originated from destructive pitting and spalling areas in the vicinity of tooth pitch line and propagated toward tooth region of tooth....
Mackaldener and Olsson [27] studied the tooth interior fatigue fracture considering the hardness and residual stress gradients through a numerical simulation method and gear fatigue tests. When evaluating the high cycle fatigue performance, the mutiaxial fatigue criteria and the damage accumulation rules...
Observation of Fatigue Fracture Surface of Carburized Steel Rotating bending fatigue tests were conducted on the gas carburized specimens with internal oxides and non-martensitic microstructure beneath the surface. ... T Naito,H Ueda,M Kikuchi - 《Journal of the Society of Materials Science Japan》...
