在ISO/DP6336—88中,有几个问题交特得不够清楚,国内对此也未见明确的解释。现将这些问题及其解决办法分析如下,供参考。一、刚性联接齿轮的当量质量动载系数k的计算中,在确定临界转速比N时,是将相啮台的轮齿根据等效质量原理简化成双质量振动系统进行处理的。弹簧刚度取为轮齿的啮台刚度Cr,而两质量即为小轮及大轮转化到啮台线上的单位齿宽当量 In ISO / DP6336-88, there are a few problems that are not clearly understood and there is no clear explanation in this regard. These problems and their solutions are analyzed as follows for reference. I. Equivalent mass of rigid coupling gear In the calculation of dynamic load factor k, when determining the critical speed ratio N, the gear teeth of the phase gear are simplified into the dual mass vibration system according to the equivalent mass principle. The spring stiffness is taken as the gear tooth surface stiffness Cr, and the two masses are the unit tooth width equivalent
