Improper removal of vibrating screen of SKF bearings, bearing internal damage may be. Pollutants may enter the SKF bearings installed or may generate errors. Therefore, removing vibrating bearings must be very careful, the axis must have appropriate support, otherwise demolished power might hurt SKF bearings.
1, perimeter demolition
Demolition of the interference fit outer ring in advance on the circumference of the shell sets the extrusion screw several outer rings with screws, and equally tighten the screw. Demolition. Blind plug the screw holes on the usual cover, vibrating screen separation such as tapered roller bearings bearings, the setting shell shoulders several incisions, using the pad, press remove, or gently beating demolition.
2 cylindrical holes, vibrating screen of SKF bearing removal
Demolition of inner ring, can pressure machine pull the latest simple. At this point, should pay attention to the inner ring to sustain its pullout.
Large vibrating screen disassembly using hydraulic method of inner ring of the bearing. By setting the oil hole oil pressure on the axis, so easy to draw. Width large SKF bearings for oil injection combined with drawing fixture, the demolition job.
Vibrating screen of NU, NJ type cylindrical roller bearing inner ring removal can take advantage of induction heating method. Local heating in a short time, after the inner ring expansion method for drawing.
3, taper hole of SKF bearing removal
Demolition of the relatively small bearings with a SKF adapter sleeves, fastened in the document supporting the inner ring on the shaft and nut back after several times, use the pad with a hammer beating demolition.
