According to the installation of outer spherical ball bearing, use, maintenance, maintenance of technical requirements, the sliding bearing of outer spherical ball bearing on the operation of load, speed, temperature, vibration, noise and lubrication condition monitoring and inspection, found that abnormal immediately to find the reason, adjustment, so that it is back to normal.Outer spherical ball bearing using factors mainly refers to install, use, maintenance, maintenance, repair and so on meets the technical requirements.
Installation conditions is to use one of the primary factor of factors, not because of the installed bearing are often caused by composite bearing optimum bearing stress between the parts of a complete set of changes, bearing in the abnormal state of operation and the service life of the early end internal factors mainly refers to the structure design, manufacturing process and material quality of the three major factors in determining the quality of bearing.
Bearing materials of metallurgical quality were the main factors influencing the premature failure of the rolling bearing.As metallurgy techniques (such as vacuum degassed bearing steel) progress, raw material quality is improved.Raw material quality factor in the bearing failure analysis share has declined obviously, but it is still one of the main influence factors of bearing failure.Select material adequacy is still bearing failure analysis factors must be considered.
Bearing manufacturing generally go through forging, heat treatment, cutting, grinding and assembly, and multi-channel processing operations.The rationality of the processing technology, advanced, stability will also affect the life of outer spherical ball bearing.Which affects the quality of finished products bearing heat treatment and grinding process, tend to have a more direct relationship with bearing failure.In recent years the study of metamorphic layer of bearings working surface show that the grinding process and is close to the surface quality of the bearing.
The main task of the bearing service life analysis, is based on a lot of background material, analysis data and failure forms, find out the main factors of bearing failure, so that the improvement measures are put forward, prolonging bearing, avoid premature failure of the bearing of the sudden.
(1), used carefully.
In use for bearing strong impact, will produce scar and creasing, become the cause of the accident.Severe cases, can crack, fracture, so must pay attention to.
(2), maintain the cleanness of bearing and its working environment.
Even the eyes can't see the little dust, also can bring bad influence to outer spherical ball bearing.So, keep the surrounding clean, dust from invading bearing.
(3), to pay attention to the corrosion of the bearing.
Operating outside the spherical ball bearing, the sweat will become the cause of rust.Pay attention to the operation with clean hands, it is better to try to bring gloves.
(4), use the appropriate operating tools.
Avoid to existing tools to replace, must use the appropriate tools.
