What aspects of bearing inspection are there? Bearing tell you

The check of the bearing 1 key has the following several aspects. Bearing the quality of the bearing box, first, check the RunHua grease have mildew, cluster, residue, such as poor condition, it is an important part of the resolution bearing damage reason. Second, check the bearing have damaged; Check the bearing inner and outer ring, rolling body, maintains the smoothness of the surface and if there is any crack, rust, molting, dent and overtemperature fading, accurate measurement of the bearing clearance is excessive; Did check the coupling damage, pit points, molting, if you have above should be changing a new bearing. 2. Interaction bearing bearing installation bearing inside diameter and shaft, diameter and chassis of interaction is critical, when the interaction is too loose, interaction can cause the relative sliding surface is called the stress relaxation. Stress relaxation to damage once cooperate with each other, or casing damage axis, and will damage the powder invasion of bearing internal cause burning, vibration and destroyed. Interference is too large, will cause the outer diameter to narrow or inner hole diameter increases, reduce the bearing internal clearance. To choose suitable main use of mutual cooperation, take into account the characteristic of bearing load, standard size, temperature, shape of inner hole of the lateral rotation all kinds of standard elements. 3. Bearing various mutual fit clearance adjustment bearing gap is too small, because the grease shear friction damage within the gap is too big, can cause bearing burning, in addition, the gap is too small, residual oil will reduce, ihave to calorific value caused by friction, will further improve the bearing temperature. But the gap is too large will change the driving force of the bearing characteristics of motor rotor run unstable. And therefore must be the same for the machinery and equipment and application of standard selected check bearing clearance. Above is today the author give you share content, to learn more about bearing small knowledge, pay attention to the bearing's official website.
