the influence law of gear's bending stress affected by nominal pressure angle and technological angle of tooth profile has been summarized and obtained a conclusion that the maximum bending stress before running in period occurred at the waist place of the tooth, thus provided a theoretical foundation for the design and application of double arced gears 总结了名义压力角和齿形工艺角对轮齿弯曲应力的影响规律,并得出跑合前最大弯曲应力发生在齿腰处的结论,为双圆弧齿轮的设计和使用提供理论依据。
the impact of the shape-change trend towards round on bending stress during the process of pressure increase was researched, a common formula and a simplified one for bending stress calculation were established, the formula of maximum bending stress caused by round degree of cylindrical vessels was deduced, the calculation method for wall thickness of pressure vessels of elliptical cross section was introduced 摘要研究了椭圆形截面容器在升压过程中的趋圆变形对弯曲应力的影响,建立了弯曲应力通用计算公式和简化计算公式,导出了由圆度引起的圆筒形容器最大弯曲应力计算公式,给出了椭圆形截面容器壁厚的计算方法。
