在实践中,即使具有良好工艺状态的高精度滚珠轴承,在其装入电机之后,往往会成为强烈振动的振源。分析表明,这种现象的原因是由于轴承安装时的误差以及与其相配合的零件在制造上的误差而引起轴承圈歪斜所造成的。轴承圈的歪斜除激发振动外,还大大地影响到转动系统的动态,使作用于轴承上的力重新分布,从而也缩短了它的使用寿命。就精密的和低噪音的电机来说,装配时检验轴承
In practice, even high precision ball bearings with good process conditions often become sources of strong vibrations after they are loaded into a motor. Analysis shows that the reason for this phenomenon is due to the installation of the bearing error and its matching parts in the manufacturing error caused by the bearing ring skew caused. In addition to the vibration of the bearing ring, the bearing ring also greatly affects the dynamics of the rotating system, redistributing the forces acting on the bearing and thus shortening its useful life. For precision and low-noise motors, inspect the bearings during assembly
