1, the outer ring of the disassembly
Demolition of the interference fit outer ring, the outer ring arranged beforehand several on the circumference of the shell with a screw extrusion screw, a fastening screw equally, while the demolition. The screw holes usually cover a blind plug, the separation bearing tapered roller bearing, in the casing retaining shoulders set up several notches, using the pad, press remove, or gently beating demolition.
2, a cylindrical hole bearing removal
Demolition of inner ring, can be used to pull out the simple mechanical pressure. At the same time, we should pay attention to inner bear the pulling force. The inner ring of large bearing removal using hydraulic method. The oil through the oil hole is arranged on the shaft, so easy to draw. Width of FAG bearings oil injection combined with drawing fixture, disassembly operations. The inner ring of NU type, NJ type cylindrical roller bearing can be disassembled by induction heating method. Local heating in a short time, the inner ring of the drawing after expansion method.
3, cone bearing removal
Demolition of relatively small adapter sleeve bearing inner ring, support with the fastening on the shaft block, the nut back after several times, using the pad with a hammer beating demolition. Large FAG bearings, hydraulic removal easier, oil hole on the cone axis of pressurization oil, so that the expansion of the inner ring, method of disassembling bearing. In operation, a bearing prolapse may suddenly, the best will use nuts as a block as well.
