Reasons and countermeasures for damage to the limit speed of bolted roller bearings

Reasons and countermeasures for the damage of the limit speed of the bolted roller bearing Generally speaking, the accurate application of the bolted roller bearing can achieve a long life. However, if an accidental early damage occurs, it can no longer be used. Unlike fatigue life, this early damage is called failure or failure. Many reasons are due to poor consideration of placement, application, and lubrication, foreign matter intruding from the outside, or insufficient research on shafts and bearing housings. The damage of the bolted roller bearing, such as the abrasion of the ring rib of the roller bearing, may be caused by insufficient lubricant, inappropriate trademark, defective oil supply and discharge layout, foreign matter intrusion, bearing installation error or excessive deflection of the shaft. , and also may be caused by the above reasons. Therefore, it is very difficult to know the real cause of the damage only by observing the bearing damage to the Tiida plane bearing. However, if you fully inquire about the machinery, working conditions and peripheral layout of the applied bearing, clarify the situation before and after the failure, and then analyze the damage of the bearing and various related reasons, you can prevent similar failures from happening again. Bearing damage causes and countermeasures that represent Tiida's flat bearing properties. Even if it adopts the advanced manufacturing technology of modern Tiida plane bearings, the rotating bearing parts are processed. Observe the method of Tiida plane bearing to observe the change of its reading with the preload load. The preload method has its downsides and is well known. The working surface will always have the appropriate part of the dial indicator against the bearing end face or shaft. 1. Bearing layout and enlistment conditions. Different layouts apply to different enlistment conditions; different layouts of automobile bearing parts have different processing techniques, which also affects their quality. Therefore, we should develop new layout products to adapt to different enlistment conditions, and can explain the applicable enlistment conditions or performance on the rotating bearing application description to facilitate customers' selection. 2. Strengthen the research on the technology of Tiida plane bearings, improve the processing technology, improve the processing quality, and reduce the possibility of defects in processing. For example, in terms of heat treatment, for larger types of inner and outer rings, although the middle and lower quenching heating temperatures are used, Tiida plane bearings are adapted to extend the holding time to improve the alloy concentration, increase the fracture strength of martensite, and ensure the quality. Select a higher tempering temperature to enhance the impact toughness of the workpiece. 3. Improve processing monitoring methods to stimulate the improvement of processing quality. Such as improving the monitoring of the curvature position of the flow channel, improving the overall performance of the automobile bearing installation, and improving the working condition of the rotary bearing and the flat bearing.
