Damage of bearing vibration is very sensitive, such as peeling, indentation, rust, crack, wear of bearing vibration measurement reflected, therefore, by using a special measurement of bearing vibration (frequency analyzer etc) to measure the vibration of the size, frequency cannot infer abnormal. SKF bearing due to different conditions of use or the sensor measurement of the position, so every machine, and comparative analysis of standard measurement values previously determined.
Is often manifested in the high temperature anomaly. Bearing lubrication oil temperature is harmful. Sometimes can be attributed to the overheated bearings bearing lubricating oil. If the bearing in more than 125 ℃ long-term continuous transmission bearing life. Bearing caused by including high temperature causes: lack of lubrication and lubrication, lubricant. Containing impurities, overload, bearing seal damage, lack of space, and generate high friction sealing. When it is damaged, may cause the importance of equipment downtime, so it should be added other bearing temperature detectors.
Pay attention to installation direction angular contact ball bearing. Angular contact bearings with contact zone of a duck egg circle, and only bear axial thrust at a party. In the opposite direction actor assembly FAG bearing, because the ball is raceway edge, the surface will germinate the groove shape wear belt. Because this should pay attention to the installation of the installation direction accurately.
Assembly contact surface on the outer ring of the bearing, exposed circumferential abrasion or discoloration, is composed of a bearing matched parts fit too loose caused. Corrosion initiation oxide as a pure brown natural abrasives, the final results will lead to bearing wear, further heating Huhu initiation noise and initiation a series of problems jump, because the assembly should be accurate and proper.
And as the spherical raceway track wear serious, suggesting that by appropriate tight bearing gap smaller, because the torque is increased, the bearing temperature rise, make the NSK bearing soon due to wear and fatigue and loss of effectiveness. At this time, as long as the appropriate reduction of radial gap, less interference can solve this problem.
