Effect of negative clearance on dynamic characteristics of high-speed high-temperature thin-walled cylindrical roller bearings

摘要

摘要: 计算了圆柱滚子轴承径向游隙为负值时的等效径向预紧载荷，并考虑等效径向预紧载荷下的套圈弹性变形，通过求解包含套圈弹性变形-接触变形-等效径向预紧载荷的非线性方程组，得到负游隙圆柱滚子轴承内部的载荷分布情况，以及负径向游隙带来的套圈周向应力.以此分析了负游隙对轴承承载性能及疲劳寿命的影响.结果表明：负径向游隙能够有效降低轴承打滑率，但同时也会降低轴承疲劳寿命，因此在负游隙设计时需同时考虑打滑率和轴承寿命，选择恰当的负游隙.

Abstract: A equivalent radial preload analytical model was developed by taking negative clearances and elastic deformation of cylindrical roller bearings into account. Loading characteristics and internal hoop stress of rings were calculated by this model. Results showed that negative clearances decreased the maximum contact pressure and cage sliding ratio, but made the fatigue life decline at the same time. So it's necessary to take cage sliding ratio and fatigue life both into account when designing negative clearance roller bearings.
