Wear of related parts of roller bearing of vertical mill

28 Sep,2020 UTC+8 Views:


 Because the assembly requirements for roller bearings of vertical roller mills are relatively strict, many companies use the method of directly cooling the bearings in dry ice for assembly.

During operation, if there is a gap between the bearing and the bearing seat, it will directly affect the operation of the bearing and cause the bearing to heat up. In severe cases, it will directly cause the bearing to sinter. There are many factors that need to be considered when repairing it. For example, traditional repair welding and brush plating methods have certain drawbacks. The thermal stress generated during repair welding has an impact on the material of the bearing. In severe cases, it will deform or break. When brush plating (the pollution is more serious), there is a limit to the thickness, so the use will also be limited.

Because the polymer conforming material has certain strength and hardness, but also it has a certain degree of concession, it can be repaired by other processes to match the size of the casting part and the matching part, and it can also use the advantages of the conforming material to absorb external forces. The impact can resolve or offset the radial impact of the bearing on the shaft, which can avoid the appearance of gaps and secondary wear between equipment.
