Most of the bearing damage is due to a number of loads beyond the original estimate; such as non-useful seals, excessively small bearing clearances caused by over-tight cooperation, etc. Any of these elements have their particular damage type and Special traces of damage will be left. Thus; inspection of the bearing of the damaged shaft; in most cases, the cause of its ability can be found. In general; one-third of bearing damage is caused by fatigue damage; the other third is due to poor smoothness; the other third is due to contaminants entering the bearing or the device is not properly handled.
However, these types of damage are also related to industrial types. For example, the pulp and paper industry is mostly due to poor smoothness or contamination to form bearing damage rather than data fatigue.
The bearings are attributed to the fine parts; therefore, the requirements are appropriate and stable when used; even if high-performance bearings are used; if they are not properly used, they cannot reach the expected function; and the bearings are simply damaged. Therefore, the following should be applied to the bearings. matter:
First, adhere to the sanitary environment of the bearing and its surroundings, even if small dust that is invisible to the naked eye enters the bearing; it will also add bearing wear; oscillation and noise.
Second, the use of the device should be careful not to allow strong stamping; do not allow the hammer to directly hit the bearing; do not allow the pressure to pass through the rolling body.
Third, use appropriate and precise equipment to try to use special things; it is necessary to avoid the use of cloth and short fibers and the like.
Fourth, to avoid the corrosion of the bearing directly when taking the bearing by hand; to wash away the sweat on the hand; and apply high-quality mineral oil before operation; especially in the dry season and summer to pay attention to rust.
However, under certain special operating conditions; the bearing can obtain a better life than the traditional accounting; especially in the case of light loads. These special operating conditions are; when the rolling surface (track and tumbler) is smoothed The oil film is useful to separate and confine the external damage that can be caused by contaminants. In fact; under ambition; the so-called Essence bearing life is capable.
Bearing life The number of life of the rolling bearing is defined by the number of revolutions (or the number of hours of operation at a certain speed): the bearing within this number of hours; should be fatigued on any bearing ring or rollover. Or incomplete). But whether in laboratory experiments or in practice, it can be seen significantly; the appearance is the same under the same working conditions; the life expectancy is very different. There are also several different definitions. The bearing "life"; one of them is the so-called "operating life"; it indicates that the actual life of a bearing before it is damaged is caused by wear and damage, which is generally not caused by fatigue; , corrosion, seal damage and other reasons.
