摘要
分析了起重机减速器变载荷工况下等效载荷的计算方法,推导出齿轮疲劳强度计算和轴承疲劳寿命计算时不同的使用系数计算公式,并根据寿命系数重新计算了用于齿轮疲劳强度计算时的指数值。指出了齿轮和轴承疲劳计算时载荷谱系数的不同之处。计算方法对起重机减速器设计计算具有指导性意义。
The calculation method of equivalent load for crane reducer under variable load condition is analyzed.Application factor formulas for the calculation of gear fatigue strength and bearing fatigue life are deduced,and the index value of the fatigue strength calculation of gear is recalculated based on the life coefficient.In addition,the differences of load spectral coefficients in gear and bearing fatigue calculations are pointed out.The calculation method has a guiding significance for the design and calculation of crane reducer.
