The speed of the INA bearing vibration when solving

INA bearings can reach the speed limit of the. Usually depends on the material used in lubricant and bearing parts can reach operating temperature. Bearing operating temperature limit is reached when the rotating speed, depending on when the rolling bearing because of the heat generated by the friction ( Include any other external heat) And how many quantity of heat can be taken from bearing. INA bearing type and size, internal structure, bear the load, lubrication and cooling conditions, the structure of the cage, manufacture precision and clearance, etc. , to the speed of the bearing can achieve has certain influence. In the related products are usually listed in the table of the two different definitions of the rated speed; The reference speed ( Associated with heat) And the limit speed ( Related to physical structure) , both of which are based on the consideration of the different parameters. Most of the INA bearing damage for many reasons, such as more than previously estimated load, the effective sealing, tight fit too small, as a result of bearing clearance, and so on. Any of these factors factors there is its special damage forms and will leave a special signs of deterioration. Therefore, examining the damaged shaft bearing, in most cases can find its possible causes. Generally speaking, a third of the INA bearing damage resulting from the fatigue damage, a third of the other resulting from poor lubrication, a third of the other resulting from pollutants into the bearing improper handling or installation. However, the damage pattern is also related to industrial don't. Pulp and paper industry, for example, mostly due to bad lubrication bearing damage or contamination is not due to material fatigue.
