The electric spindle bearing has noise, can replacing the bearing solve it?

'Why does replacing the electric spindle bearing sometimes eliminate the noise, and sometimes not?' I talked to many people about these issues before, and everyone sometimes even complained that the noise of the bearing is like a Feng Shui metaphysics problem. It's fine that you don't know how, but sometimes it's hard to fix anyway. Is this really the case? Motor noise problems are a very common phenomenon that confuses customers. Regardless of the motor manufacturer or the user of the motor, a 'rote method, take care of one thing and lose the other' method is to change where it doesn't work. Therefore, the method we adopt on site is to change the bearing when the bearing rings. The method of 'replacing the bearing when the bearing rings' is sometimes really reasonable on site, but in a large number of cases, no matter how you change it, there should be some noise or there may be some noise. A more detailed understanding of such things is: replacing the bearing can reduce noise. It may be the problem of the bearing itself, but it may not be. If the bearing is replaced and the noise is still not reduced, the high probability indicates that it is not necessarily caused by the bearing. First, if it is the problem of the electric spindle bearing itself, then replace the bearing with no problem, and the noise will of course be reduced. The premise is: the replacement bearing does not have any quality problems. And the replacement method is appropriate. Second, if the process of assembling the bearings is wrong, every installation will cause damage to the bearings, so no matter how the bearings are replaced, the noise will never be resolved. In addition to the process method, assembly also needs to consider whether the process technology is stable. For example, the bearings are also assembled by beating. If the bearing is damaged by knocking, the possibility of bearing noise is greatly increased; and when the next bearing is installed, the knocking is relatively light, and the bearing is hardly damaged, so the noise of the bearing after installation will naturally be small. If this noise difference is attributed to the electric spindle bearing itself, it is obvious that no direct cause has been found. After a long time, such looming bearing noise problems cannot be completely eliminated. Third, if there is any problem with the shape tolerance of the bearing seat or the shaft member, the noise may or may not be improved after the spindle bearing is replaced. First of all, if the bearing seat or the shaft has a slight dimensional tolerance deviation, after the first bearing is assembled, the internal structure of the bearing will be squeezed and the dimensional tolerance deviation will cause noise. If the slight misalignment is adjusted, then there is no possibility of abnormalities in the installed bearings. Secondly, for the situation where the dimensional tolerance deviation is relatively serious, even with the 'adjustment' of the previous bearings, it is still impossible to adjust the product workpiece back within the tolerance range. So no matter how you replace the bearing, the noise will still exist. It can be seen from the above examples that if there is any problem with the electric spindle bearing itself, it is reasonable to replace the bearing. If the problem isn't the bearings at all, then replacing the bearings may or may not work. This confusing situation is very harmful. It is strongly recommended that when encountering bearing noise problems, it is necessary to refer to certain methods to find the root cause of the problem, rather than simply changing the bearing. Finding the cause of the disease can treat the symptoms rather than the root cause. Only when the torque is accurate can the rotation be stable! (http://)
