摘要
针对高速球轴承塑料保持架在高速工况下易脱落的问题,以2种不同结构的塑料保持架为研究对象,建立有限元模型,分析了转速及保持架结构特征(锁口侧切、减重凹槽及侧梁宽度)对保持架变形的影响,并搭建试验台验证了模型的正确性,结果表明:随转速升高,保持架兜孔锁口变形增大,较多镂空和切割设计的小质量保持架变形较大;保持架侧切结构补全后,保持架变形增大;缩小减重凹槽和增大侧梁宽度,保持架锁口变形减小。
Aimed at the problem that the plastic cages of high-speed ball bearings are easy to fall off under high-speed working conditions, taking two kinds of the cages with different structures as research objects, the finite element model is established, and the influence of rotational speed and structural characteristics of the cages(counterbore side cutting, weight reduction groove and side beam width) on deformation of the cages is analyzed. A test bench is built to verify the correctness of the model. The results show that: with the increase of rotational speed, the deformation of counterbore of cage pocket increases, and the deformation of small mass cages with more hollow and cut design is larger;the deformation of the cages increases after completion of side cutting structure of the cages;the deformation of counterbore of the cages is reduced by reducing the weight reduction groove and increasing the side beam width.
