The NSK aligning ball bearing failure is often multifactorial, and all design and manufacturing process factors and bearing failure, analyzing them is not easy to judge.
Under normal circumstances, in general, from the use of factors and internal factors to consider and analyze.
Using the factor mainly refers to the installation and adjustment, maintenance, maintenance, repairs, etc. to meet the technical requirements. Installation conditions is one of the primary factors bearing often by the installation of inappropriate changes lead to the stress state of the entire bearing various parts NSK-aligning ball bearing operation and early failure in the normal state.
Bearing installation, use, maintenance, maintenance, technical requirements, bear on the operation of the bearing load, speed, operating temperature, vibration, noise and lubrication condition monitoring and inspection, abnormal immediately find reasons to adjust to back to normal. In addition, the grease quality and the surrounding media, and the atmosphere is also very important to carry out analytical testing.
The internal factors mainly refers to three major factors of the decision bearing the quality of structural design, manufacturing processes and materials quality.
First of all, reasonable structure design have advanced nature will have a longer bearing life. The manufacture of bearings generally have to go through a multi-channel processing such as forging, heat treatment, turning, grinding and assembly.
The rationality of the process, advanced, stability will also affect the bearing life. Which affect the quality of the finished bearing heat treatment and grinding process, and often have a more direct relationship with the bearing failure. In recent years, the grinding process and the quality of the bearing surface is closely related to the bearing surface deterioration layer.
NSK-aligning ball bearing metallurgical quality of the materials used to influence the Rolling early failure of the main factors. Metallurgical technology (such as advances in bearing steel vacuum degassing, etc.), raw material quality is improved. The proportion of raw material quality factors in the analysis of bearing failure has decreased significantly, but it is still one of the main factors bearing failure. The selection of the adequacy of the still bearing failure analysis must take into consideration.
NSK-aligning ball bearing failure of the main task of the analysis is based on a lot of background material, analyzing data, and the form of failure to identify the main factors that cause bearing failure, so that proposed improvements to extend bearing service period, to avoid bearing the early occurrence of sudden failure.
