Why the motor bearing damage

Motor running shaft problem cause of bearing burning 1. Motor axial channeling dynamic problems usually use most frequently is deep groove ball bearings and cylindrical roller bearing. And when decorate, end do axial positioning, on the other side do the axial float. Axial positioning if reliable, deep groove ball bearing axial channeling momentum should be its axial clearance, generally will not be too big, but depends on the choice of radial clearance. For cylindrical rod bearing ( N and NU series bearing) , cannot serve as locating bearing, otherwise, I'll move too much. Bearing burning problem if too much positioning bearing axial load, will cause bearing burned. So, to understand when choosing location bearing axial load, whether the selected bearing bore. If is the NJ series cylindrical rod bearing the axial load is entirely by sliding a partial bear, so I can't. For deep heavy ball bearing, the axial capacity up to only a quarter of the radial, for different bearings are different. The motor shaft are now to HuiCuan, rely on a waveform spring washer to adjust, but still able to move. Shafting are generally required axial positioning. So you need to end as a positioning side, the other end as swimming. Waveform spring is not used to locate, is used to add axial preload. So, to cross positioning of the motor, is bound to exist waveform spring washer caused by axial channeling. To control motion, which make the traditional a positioning, the positioning end, and then on the positioning and waveform spring washer. According to the change of bearing grease color determine bearing running state is judged by the color of the grease bearing operation is normal, more difficult. Because of different internal grease additives is different, different running conditions, to adapt to the different temperature range, there can be no unified standard. Even the same kind of grease, also may be due to the production batch is different, a slightly different formula, and the difference of color. Therefore, in order to change color as a basis for may vary. In addition, even if not in bearing grease, would become angry. This is because the grease oxidation problems.
