摘要
针对轴承制造过程中形成的粗糙度、波纹度、圆度等影响轴承振动的主要因素,利用Lagrange动力学方程建立了具有表面特征的滚动轴承系统的振动模型.该模型可用于分析轴承各部件的表面特征对轴承振动的影响,同时也可用于分析轴承各部件表面存在加工缺陷时系统的振动特性.以轴承内外圈和滚动体表面的波纹度为例,从理论上推导了波纹度阶数与系统振动频率的关系,仿真结果验证了该模型的正确性,所得的结论对轴承振动理论研究和指导低噪声轴承生产有重要意义.
This paper applies Lagrangian dynamic equations to establish a vibration model of roller bearing systems based off component roughness, waviness, roundness, etc. It can be used to analyze how surface characteristics of a bearing system generated by manufacturing defects effect bearing vibration. Taking this waviness of the inner ring, the outer ring, and the surfaces of ball bearings, for example, this paper derives the relationship between waviness order and vibration frequency of a system. Both theoretical analysis and numerical simulation demonstrate the effectiveness of the proposed model. These results can aid theoretical studies and lead to production of lower noise bearings.
