摘要
针对整体式、无装球缺口的自润滑铝合金关节轴承无法采用传统方法装配的问题,提出采用施加预载荷使内、外圈产生弹性变形的装配法。以某轴承为例,基于ANSYS建立套圈仿真分析模型,分析了预载荷作用下内、外圈的最大等效应力和变形,结果表明内、外圈最大变形量之和大于外圈沟底深度,可以采用内、外圈弹性装配法。实际装配后轴承整体外观良好,旋转灵活,进一步证明了装配方法的可行性。
In order to solve the problem that the integral self-lubricating aluminum alloy spherical plain bearing without ball notch is unable to assemble by traditional methods,the assembly method is proposed by applying preload to make the inner and outer rings produce elastic deformation.Taking a bearing as an example,a simulation analysis model of ring is established based on ANSYS to analyze the maximum equivalent stress and deformation of inner and outer rings under preload.The results show that the sum of maximum deformation of inner and outer rings is greater than groove bottom depth of outer ring,and the elastic assembly method of inner and outer rings can be adopted.After actual assembly,the overall appearance of the bearing is good and the rotation is flexible,which further proves the feasibility of assembly method.
