2102 薄肉対称ウェブ構造はすば歯車の歯元応力と曲げ疲労強度に及ぼすリム・ウェブ厚さの影響(歯車の疲労強度,一般講演)

抄録

This paper presents a study on effects of rim and web thickness on root stresses and bending fatigue strength of thin-rimmed helical gears with symmetric web arrangement of various rim and web thickness. Measurement of root stresses and bending fatigue test were carried out for thin-rimmed helical gears with symmetric web arrangement of various rim and web thickness. The changes of the root stresses from the beginning of engagement to the end of engagement, the meshing position (worst loading position), where the maximum root stress occurred, the effects of rim and web thickness on bending fatigue strength and bending fatigue cracks were clarified. Furthermore, the results obtained were compared with the solid helical gear results.
