Bearing 6305: bearing is broken can appear like a whistle buzzing sound

Early failure of bearing from mainframe to parts of the manufacturing accuracy, installation quality, conditions of use, the lubrication effect, external, thermal effect and host factors such as sudden failure. If A and B on both sides of the vertical vibration reverse phase, or of A and B on both sides of the vertical vibration in phase, the support stiffness asymmetry, but both sides will result in the two cases and the axial vibration of the bearing. To prevent corrosion of measures: pay attention to the bearing safekeeping, avoid contact with corrosive medium, when installing the bearing cleaning carefully, and wear gloves to avoid perspiration on bearing on the working plane. To do a good job of preparation, that is, the removal of equipment, tooling processing, related tools and the preparation of personnel to ensure enough space construction and safe working environment; 。 Pushed to the required location for installation. Bearing damage caused by measuring oil gear clearance values, for many reasons, such as improper installation, dirt or moisture is a lot of bearing a common cause of early damage, x. NO, usually, can use the following method to deal with this kind of failure: first in the shaft neck surfacing welding the wear area, and then to the required size of grinding. Low noise: balance test showed that anyone who has reached the G/G, after careful analysis found that the main shaft components of the cause of the problem a bit: spindle bearing grease undesirable. Fixed bearing lock nut method: USES the interference fit of bearing inner ring installation, often make the inner ring side against the shaft shoulder, on the other side, with a lock nut ( KMT or KMTA series) Fixed. If improperly installed, bearing not only have a vibration, noise, low accuracy, increasing temperature, but also be jammed burn out; Conversely, install well, not only can guarantee accuracy, life will be greatly extended. In equipment operation, the working procedure: the bearing surface in putting a 30 mm on both sides of the lead wire, in the same journal article put with bearing long 30 mm above the lead wire. Solution: choose reasonable tolerance, to solve the problem of water XiaoYao: @ xiao leng there are other similar water? Xiao leng: suppose is caused by water. In comparison, using UPE material has better strength, low friction and low temperature application features, Low to - ℃) As internal and external ring material is HDPE, PP, or UPE, material is HDPE, PP or UPE, ball for glass ball, stainless steel or ceramic ball.
