Improper removal vibrating screen bearings may cause damage to the bearing inside. Pollutants may enter the bearing or re-installation may produce errors. Therefore, the demolition of the vibrating screen bearings must be very careful axis must have the appropriate support, otherwise disassemble force may injure the bearings.
1, the external demolition
Removing the outer ring, the interference fit provided on the circumference of the housing in advance several outer ring extrusion screw with a screw, side evenly tighten the screw. Side demolished. These screw holes are usually covered with blind plugs, the vibrating screen tapered roller bearings and other separation-bearing, set in a housing block on the shoulders of several incision, using the pads, the presses demolition or gently beating demolition.
2, the demolition of the vibrating screen cylindrical bore bearings
The demolition of the inner ring, with pressure mechanical pull out the latest simple. At this point, we should pay attention to the inner ring to withstand its pull.
Large vibrating screen bearing inner ring disassembly using the hydraulic method. The shaft hole by setting the hydraulic pressure in order to enable easy drawing. Width bearing hydraulic method and drawing fixtures with the demolition job.
NU type NJ type cylindrical roller vibrating screen bearing inner ring disassembly can take advantage of the induction heating method. In a the heating localized within a short period of time, so that the method of drawing in the inner ring after expansion.
3, cone bearing demolition
Demolished relatively small with adapter sleeve bearing to support inner ring, shaft stopper fastening nut back a few times, using the pads with a hammer and beat demolition.
