目前，残磁对各型轴承精度、寿命等指标的影响尚无资料提供定量的数据。从定性角度分析，它可以吸引磁性物质，使轴承在运转过程中遭到破坏，同时因磁场产生的引力，加大了轴承的起动和摩擦力矩；在残磁集中处，还可因磁电效应，加剧电腐蚀速度，影响轴承的使用寿命；另外... At present, residual magnetism on the accuracy of various types of bearings, life expectancy and other indicators there is no data to provide quantitative data. From the qualitative point of view, it can attract magnetic substances, so that the bearing during operation is damaged, and due to the magnetic field generated by gravity, increased bearing start and friction torque; in the residual magnetic concentration, but also due to magnetoelectric effect , Aggravate the electric corrosion rate, affecting the service life of the bearing; In addition ...
