Bearing is contemporary carpenter grinding machine cnc woodworking machine
machinery complete set equipment is an important component.
Its main function is to support the mechanical rotator, reduce the coefficient of friction in the process of the movement, and ensure the accuracy of inversion.
As our demand for bearing is more and more big, the bearing of the premature failure, life is not long, and so on questions bothering each mechanical enthusiasts.
cold press bearing premature failure reason why?
How to progress the bearing life spans?
Due to its high efficiency analysis for you is as follows: under the relative load, bearing in case of pitting experience before the revolution or hours, referred to as the bearing life.
Within the full bearing, should be in any of its bearing ring or on the rolling body began to fatigue damage.
In our daily practice, however, can be significant observed that under the same working conditions the appearance of the joint bearing, a good practice is different.
What is the cause?
1, the device overshooting, its ornate hammer bearing to bearing damage is larger;
Also is the main reason for the forming deformation.
2, installation error or not installed to the bearing, bearing clearance is too small.
Inside and outside the circle is not in the same rotation center, forming different heart.
Proposition: select the appropriate or professional bearing assembly tools, end with a special instrument to detect device.
Second, the pollution,
Accounts for about 14%)
Pollution can also cause premature bearing damage, pollution is refers to the dust, metal scraps into the bearing inside.
Main reasons include: apply early to open the bearing before packing, formation pollution;
Device when the working environment is not clean, formation pollution;
Bearing of the working environment is not clean, working medium pollution, etc.
Proposition: don't unpack the bearing before use;
Device when the device environment clean, to use bearing for cleaning;
Enhance the bearing sealing device.
Three, smooth bad (
Accounts for about 50%)
According to the survey, smooth adverse is formed one of the leading causes of premature failure of the bearing.
Contains no timely smooth filling agent or smooth oil;
Smooth agent or smooth oil not filling in place;
It is no good smooth agent or smooth oil selection;
Smooth method is not correct, and so on.
Proposition: choose the correct smooth agent or smooth oil, using correct smooth filling method.
Accounts for about 34%)
Fatigue damage is a common damage bearing method.
Common causes of fatigue damage could be: bearing overload for a long time;
Failed to timely repair;
It is no good repair;
Abnormity grinding machine aging, etc.
Proposition: select the appropriate bearing type, timely replace exhausted bearing on a regular basis.
