SKF bearing failure analysis of main tasks is based on the large amount of background material, analysis of data and failure modes, identify the main factors contributing to failure so that targeted measures for improvement, and extended bearing service, avoid sudden early bearing failure.
First of all, along with advancement of the reasonable structure design, SKF bearings have longer life expectancy. Bearing manufacturing generally after forging, heat treatment, machining, grinding and assembling multiple processing procedure. Rationality, advanced processing technology, can also affect the stability of the bearing life. Which affect the finished product quality SKF bearing heat treatment and grinding operations are often associated with failure of the bearing has a more direct relationship. Study on bearing surface degenerating layer in recent years shows that close to the surface quality of bearing grinding process.
1, note bearing installation
Bearing is properly installed, which will affect accuracy, longevity, performance. Therefore, design and Assembly departments for installation of bearing products to fully study. Want to follow the standard installation. Standard projects are usually as follows:
(1) clean bearing and related parts;
(2) check the sizing and finishing of correlative parts;
(3) installation;
(4) when the bearing is installed check;
(5) supply of lubricants. Bearing installation carefully this five-step
2, tuneup, straightening
SKF bearing after installation, if not carefully tuned, straightening may lead to bearing subjected to additional loads, friction and vibration. This might accelerate fatigue and reduced bearing service life of the product, and it may damage other parts of life, in addition to increased vibration and friction may significantly increase energy consumption and premature failure risk.
3, basic condition monitoring
During its use, to run basic external bearing condition monitoring on a regular basis, such as temperature, vibration and noise measurement, and so on. Bearing experts pointed out that these regular checks for early detection of potential problems and prevent unexpected machine suspension, make production plans can be realized, improving factory productivity and efficiency.
4, again lubrication
During the operation, requires correct SKF bearings lubricated again, perfect its performance. Lubrication of bearings products, divided into grease lubrication and oil lubrication. In order for the function of bearing products play well, first of all, to select suitable for conditions of use, use of methods of lubrication. If only lubrication, oil lubrication of lubrication-dominated. Grease lubrication can be simplified bearing structure around like that.
Periodic maintenance, operation of the SKF bearing device and other external parts replaced when SKF bearings are removed when suspended soujian, demand in turn identify the bearing components can be used again and record use of good from bad. In order to ascertain and queries visit the remaining amount of lubricant, sampled recently, a good wash bearings.
