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 總結了名義壓力角和齒形工藝角對輪齒彎曲應力的影響規(guī)律,并得出跑合前最大彎曲應力發(fā)生在齒腰處的結論,為雙圓弧齒輪的設計和使用提供理論依據。
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 摘要研究了橢圓形截面容器在升壓過程中的趨圓變形對彎曲應力的影響,建立了彎曲應力通用計算公式和簡化計算公式,導出了由圓度引起的圓筒形容器最大彎曲應力計算公式,給出了橢圓形截面容器壁厚的計算方法。
