摘要
将GB/T12759-1991型双圆弧齿轮作为分析对象,运用模糊数学理论和可靠性优化设计方法,考虑圆弧齿轮传动中许用应力的随机性和模糊性,以圆弧齿轮传动中弯曲强度和接触强度的模糊可靠度以及齿轮的模数、齿数、螺旋角、纵向重合度等为约束条件,以一对圆弧齿轮体积最小为优化目标,建立了双圆弧齿轮传动的模糊可靠性优化设计数学模型,并给出实际算例,结果表明,用模糊可靠性优化设计方法进行圆弧齿轮设计具有更好的合理性。
Taking the double arc gear in the national standard GB/T12759-1991 as the analysis object,by using the theory of fuzzy mathematics and reliability optimization design method,considering arc gear transmission allowable stress randomness and fuzziness,taking the fuzzy reliability of arc gear bending modulus strength and contact strength and the modulus,tooth number,helix angle,longitudinal coincidence degree of gear as constraint condition,a minimum volume of arc gear optimization as target,the fuzzy reliability optimum design model of double arc gear is established,and a practical example is given,the results indicate that,the circular gear design with fuzzy reliability optimization design method has better rationality.
