The most desirable pitch difference for improving the fatigue life is relatively smaller than the most suitable pitch difference for improving anti-loosening performance. In this paper, the effect of the nut height on the tightening and untightening of the pitch difference nut is investigated experimentally and analytically. It is found that the suitable pitch difference range for anti-loosening can be reduced with increasing the nut height. Therefore, the larger nut height may realize both anti-loosening performance and high fatigue strength., 本論文では,ナット高さを大きくしたピッチ差付きナットの締結力とトルクの関係を3次元FEM解析により求め,実験結果と比較して,ナット高さの緩み止め性能への影響を明らかにする.その後,疲労強度への影響についても考察し,緩み止め性能と疲労強度向上の両立できるナット高さを提案する.}, pages = {58--63}, title = {ピッチ差を有するナットの締め付け/緩ませ過程におけるナット高さの緩み止め性能への影響}, volume = {52}, year = {2020}, yomi = {ノダ, ナオアキ and サノ, ヨシカズ and タカセ, ヤスシ} }
