According to the outer surface of the bearing Sphere installation, use, maintenance, maintenance of the technical requirements for the operation of the outer bearing surface of the bearing balls to withstand load, speed, temperature, vibration, noise and lubrication condition monitoring and inspection, abnormal immediately find out the reasons, to adjust it back to normal. Sphere outer surface of the bearing using the adjustment factor mainly refers to the installation, use and maintenance, repair and other maintenance meets the technical requirements.
Installation conditions are the primary factors to use one of the factors bearing is often undesirable due to the installation of composite bearings caused by the stress state suitable package bearing between the various parts changes, bearing in abnormal state operation and early termination of the life of internal factors mainly refers to the design, manufacturing processes and materials quality three factors determine the quality of the bearing.
Metallurgical quality bearing materials was the major factor in the failure of the early Rolling influence. As metallurgical techniques (such as bearing steel vacuum degassing, etc.) progress, improve the quality of raw materials. Raw material quality factors in bearing failure analysis, the proportion has decreased significantly, but it is still one of the main factors bearing failure. The selection is still appropriate factors bearing failure analysis must be considered.
Bearing manufacturing generally through forging, heat treatment, turning, grinding and assembly of multi-channel processing. The reasonableness of the processing technology, advanced, stability will also affect the life of the outer surface of the bearing balls. Which affect the quality of products bearing the heat treatment and grinding processes, often have a more direct relationship with the failure of the bearing. In recent years, research on the bearing surface metamorphic layer showed that the grinding process is closely related to the bearing surface quality.
The main task of bearing life analysis is based on a lot of background material, analysis of data and failure modes, failure to identify the main factors causing the bearing to make targeted improvements to extend bearing service period, to avoid the occurrence of unexpected bearing early failure.
(1), exercise extreme caution.
Give as bearing a strong impact, it will have scars and indentations, a cause of the accident. In severe cases, it will crack, break, care must be taken.
(2), kept clean and bearings work environment.
Even the eyes can not see the small dust, will give the outer surface of the bearing balls adversely affected. Therefore, to keep the surrounding clean, so that the dust will not invade bearings.
(3), pay attention to corrosion of bearings.
Operation outer surface of the bearing balls, the hands sweat will become rusty reasons. Pay attention to clean hands operation, the best possible wear gloves.
(4), with a proper operation tool.
Avoid existing tools in place, you must use the right tools.
