From FAG needle bearing operation sound judgment of its life

There could be many factors affecting the service life of FAG bearings use may result in the factor and the internal friction has been further instructions. Used to adjust the main factor is the installation, use and maintenance, maintenance, such as conform to technical requirements. According to the needle roller bearing installation, use, maintenance, maintenance of the technical requirements of the bearing contact load operation, speed, lubrication condition monitoring and inspection, found that the immediate cause of abnormal adjust back to normal. Installation conditions for needle roller bearing is one of the factors is often caused by incorrect installation package state changes between the parts of bearing force, the primary factor of the abnormal state of FAG bearing operating temperature, vibration, noise, and improve the quality of raw materials. The proportion of raw materials quality factors in the analysis of the bearing is markedly reduced, but it is still one of the main factors of bearing failure. Choose whether or not is still appropriate FAG bearing failure analysis must be considered. Needle roller bearing manufacturing will through forging, heat treatment, cutting, lubrication condition, to monitor and check the proximate cause of the abnormal findings to adjust back to normal. Installation conditions is one of the factors of using bearing is often caused by incorrect installation package state changes between each part of the primary factors of bearing capacity in the abnormal operation status, and early termination of the main factors of inner life, refers to the structure design, high quality manufacturing process and material, there are three factors determine the quality of the bearing. Bearings are better than even the shape will into a low hum, injuries occur on noise, the noise will be in accordance with the needle bearing speed collision and differences. If there are intermittent noise is through. If sharp hiss, squeaky voice and other sound not conform, often underperforming needle roller bearing, or even reverse the situation. Sharp make noise, is appropriate, because smooth, level off. Improper FAG bearing clearance will form the metal sound. Will cause the vibration of the bearing outer rail rail concave indentation, and form a smooth loud voice. If due to the performance of the roll, equipment parts damage. If any contaminants often cause hiss, the appearance of the scroll was damaged when on the attack. Serious damage will occur the rules of order, but it is not a lot of noise. Needle roller shaft bearing of rolling the major effect of the early failure of the metallurgical quality of a major factor. As metallurgy technology, Like a FAG bearing steel, vacuum degassing, etc. ) And other multi-channel processing and assembly process.
