What factors will cause the temperature of the special bearing for the main shaft to rise? What are the solutions? The summary is as follows: 1) The installation position of the bearing is wrong, which will cause a large axial force between the steel ball port, the inner hole of the bearing seat and the outer stopper, and cause the bearing to overheat. When assembling the bearing, the bearing force should be even and should not be hammered directly. 2) Use bearings with the required precision level. 3) During use, the special bearing for the main shaft is deformed or the hole of the bearing box (assembly) is misaligned to cause heat. The solution is to repair the main shaft bearing. 4) The tolerance fit of the bearing is too tight, and the expansion gap is too small to cause heat generation. Choose your own tolerance fit and moderate clearance. 5) Poor lubrication causes heat generation. The lubricating material of a specific brand should be selected, and it is strictly forbidden to mix grease of different brands and different viscosities. 6) Low installation quality causes heat generation. Enhanced installation quality. 7) The inner and outer rings of the bearing run hot. Replace bearings and related damaged parts. 8) Excessive axial force causes heat generation. Check the axial force balance measures and structures of the special bearings for the main shaft. 9) The bearing itself is damaged and generates heat. Replace the bearings. Only when the torque is accurate can the rotation be stable. We specialize in the production of special bearings for the main shaft! (http://)
