Bearing burn usually shows that the bearing is hot, discolored and unable to rotate. Today, I will analyze the problems and solutions of bearing burn for you.
Importance of bearing
Crusher bearing is the core supporting component of crushing equipment operation, and its performance directly determines the stability, efficiency and service life of the whole machine. In the industrial environment with high impact, heavy load and much dust, bearings bear key functions such as transmitting power, bearing radial and axial combined loads, compensating shafting deflection, etc. Any failure will lead to chain production accidents.
Solution
1. The clearance is too small. In particular, check the deformed parts to see if the clearance is too small, and then set the appropriate clearance to avoid burns again.
2. The problem of roller deflection. The roller can’t run normally in the bearing, which will produce large sliding friction and aggravate the wear. At this time, it is necessary to improve the assembly method of the bearing.
3. The problem of excessive load or preloading. Preloading can make the bearing bear the load without gap, but excessive load will aggravate the fatigue of the bearing. At this time, it is necessary to check the design and use conditions around the bearing, including the bearing heating problem caused by improper lubrication, and prevent the positioning error.
4. Improper use of lubricant. To use lubricants correctly, it is necessary not only to select suitable lubricants, but also to ensure sufficient injection to meet the lubrication needs of bearings.
