Hendin said hub bearings should pay attention to the following items:
One, to maintain the bearing and the surrounding environment clean
Even if the invisible smile dust into the bearing, it will increase the bearing wear, vibration and noise.
Two, the use of the installation should be carefully carefully
Do not allow strong stamping, do not allow the use of direct percussion hammer bearings, does not allow the transfer of pressure through the rolling body.
Three, the use of appropriate and accurate installation tools
Try to use special tools, try to avoid the use of cloth and short fiber and so on.
Four, to prevent the corrosion of bearing
Directly with hands to pick up the bearing to fully wash hands sweat, and coated with high quality mineral oil for operations, paying particular attention to rust in the rainy season and summer.
However, in some special operating conditions, the bearing can obtain longer life expectancy in traditional computing, especially in light load conditions. Hengding hub said these special operating conditions, that is, when the rolling surface (track and rolling) is a lubricating oil film to effectively separate and limit the pollutants may cause surface damage. In fact, under ideal conditions, the so-called permanent bearing life is possible.
Five, bearing life
Therefore, in the calculation of bearing size, there must be a clear definition of the word "life". All information about the basic dynamic load rating of the general offer, is a large enough number of bearing surface completely based on the same 90% can reach more than life as a basis.
The different definitions of the bearing life. One of them is "working life", said the bearings in the actual working conditions, failure to before the actual life. Hendin hub must pay attention to remind, life only individual bearing was predicted by statistical methods. Just on the reliability of bearing life calculation groups and certain procedures, about 90%. Failure in actual use is usually not due to fatigue, the situation is more pollution, abrasion, misalignment, corrosion, or fault retainer, lubricant or seal caused by.
Another kind of "life" is "life agreement" appointed by the lawsuit department or industry standards organizations, and based on an assumption that the load and speed of working conditions. This is basically the basic rating life of all bearings, is generally based on similar applications to the experience of the.
