Angular contact ball bearing of checking the impact on the use

Source: Time:2016-08-27 18:32:35 frequency:

Machine shaft parts, especially spindles, are generally thrust ball bearings assembled into one, and a high rotational speed, and sometimes will produce a very high heat. This phenomenon if not removed, will result in angular contact ball bearings overheat, and the corresponding parts of the machine temperature and thermal deformation, serious cause spindle and tailstock is not high, which not only affects the precision and accuracy of the machine itself and bearings will burn out, so usually choose high-temperature bearings.
Rated fatigue life, refers to a group of the same type of bearing, running under the same conditions, 90% of the angular contact ball bearings from total number of revolutions of rolling contact fatigue spalling due to appear. At constant speed, more than the rated fatigue life of the total running time.
In the study of thrust ball bearing life, not only consider the fatigue life, but also should have a bearing according to the performance of the integrated use of several limits to consider. For example, greased bearing grease life. Noise life, abrasion life, etc., depending on the use, limit the use of reference is different, and therefore, most of the pre-selected empirical limits.
Therefore, only the investigation angular contact ball bearing damage, it is difficult to know the real cause of injury. However, if you know the mechanical conditions of use, the structure around the bearing thrust ball bearings, to understand the situation before and after the accident, combined with state of the bearing and damage several reasons, it can prevent similar incidents from recurring.
Angular contact ball bearing is available to judge, mainly on account of the extent of damage bearings, mechanical properties, the importance of operating conditions to be determined during the next maintenance. If you have the following defects can no longer use, it must be replaced with new thrust ball bearings. Inner, outer ring, rolling body, any cracks or notches on a cage.
