Disassembly of the outer ring disassemble the outer ring of the interference fit
Be careful not to damage the bearings and various parts, especially the
disassembly of interference fit bearings, which is difficult to operate. Oil
pressure is applied through the oil hole provided on the shaft to make it easy
to draw. Use spacers to remove them with a press or gently tap them.The
disassembly of the cylindrical bore bearing The disassembly of the inner
ring can be pulled out with a press machine, the latest and simple. It is better
to use the nut as a stop.
These screw holes are usually covered with blind plugs
and separable bearings such as needle roller bearings. At this time, pay
attention to let the inner ring bear its pulling force. Removal of the tapered
bore bearing Remove the relatively small bearing with adapter sleeve,
support the inner ring with the stopper fastened on the shaft, turn the nut back
several times, and use the cushion block to knock and remove it.
When
disassembling, study the disassembly method and sequence according to the
drawings, and investigate the matching conditions of the bearing to ensure that
the disassembly operation is foolproof.The inner ring of large bearings is
disassembled by hydraulic method.Therefore, it is very important to
consider in advance the ease of disassembly in the design stage, and design and
manufacture disassembly tools according to needs. For bearings with a large
width, the hydraulic method and the drawing fixture are used together for
disassembly.　　　　
Large bearings, it is easier to disassemble by oil
pressure.The disassembly of the bearing should be carried out as
carefully as during installation.NU type, NJ type cylindrical roller
bearing inner ring can be removed by induction heating method. The oil is pumped
through the oil hole on the tapered shaft to expand the inner ring and
disassemble the bearing. During operation, the bearing may suddenly come out.
The method of drawing after heating the part in a short time to expand the inner
ring. Disassembly of the outer ring disassemble the outer ring of the
interference fit, and set several outer ring extrusion screws on the
circumference of the shell in advance, and tighten the screws evenly while
removing non-standard bearing them.
Several cuts are provided on the housing shoulders
