摘要
介绍了一种将齿轮接触疲劳强度的常规设计与可靠性设计相结合的改进计算方法。用常规设计方法计算齿轮的初始尺寸,同时用可靠性设计方法计算可靠性安全系数及可靠度。在保证齿轮合理可靠度的条件下,通过对计算结果的评价与调整,使齿轮的尺寸减小。供广大机械设计工作者在齿轮的小型化设计中选用。
A improved calculation method of combining general and reliability design of contact fatigue strength for gear is discussed. Initial size for gear is calculated with general design method, and furthmore reliability safety factor and reliability with reliability design method is calculated. By evaluation and alignment for calculating results the gear size is decreased in condhion ensured reasonable reliability for gear. This paper provides selected methods in small_ scall design of gear for machine designers.
