Why the bearing is damaged <br> The bearing is attributed to the fine part; therefore, the demand is quite stable when used; that is, the variable is the use of high-performance bearings; if it is not properly used; it can not reach the expected function; and the bearing is simple Damage. Therefore; the use of bearings should focus on the following: /*250*250 was created on 2017/12/25*/ var cpro_id = 'u3171089';
First, adhere to the health of the bearing and its surrounding environment
Even the light smile that is invisible to the naked eye enters the bearing; it also adds wear and tear to the bearing; oscillation and noise.
Second, the use of the device should be careful and careful <br> Do not 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, the use of appropriate, precise device things <br> Try to use special things; try to avoid the use of cloth and short fibers and the like.
Fourth, to avoid the corrosion of the bearing <br> When taking the bearing directly 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 <br> The number of revolutions of the rolling bearing in revolutions (or the number of hours of operation at a certain speed); the definition: the bearing within this number of hours; should start on any of its bearing rings or rollover Weakness damage (shedding or missing). But it can be seen clearly in laboratory experiments or in practice; it looks like a bearing under the same working conditions; the life expectancy is very different. There are also several kinds. Not the same as the number of bearings "life"; one of them is the so-called "working life"; it indicates that the actual life expectancy of a bearing before it is damaged is caused by wear and damage and is generally not caused by fatigue; But it is formed by wear, corrosion, seal damage and other reasons.
Why is the bearing worn and damaged?
Only some of the bearings are damaged in practice.
Most of the bearing damage is caused by many loads beyond the original estimate; non-useful seals, too small bearing clearances caused by over-tightening cooperation, etc. Any of these elements have their special damage type and will Leaving a special trace of damage. Thus; examining the bearing of the damaged shaft; in most cases it is possible to find its cause; in general; one third of the bearing damage is caused by fatigue damage; other three points One is due to poor smoothness; the other third is due to contamination of the contaminant into the bearing or device disposal.
However, these types of damage are also related to industrial types. For example, 85% of the pulp and paper industry is due to poor smoothness or contamination to form bearing damage rather than data fatigue.
