Xi'an FAG small bearing www.zhoucheng8.com general considerations for disassembly

Bearings may be disassembled, lubricated, or rectified at regular intervals for maintenance. In the process of disassembly of the bearing, it is necessary to pay attention to certain methods and techniques, otherwise it may lead to bearing damage, crack deformation, etc., resulting in failure of Xi'an FAG bearing . General drive method for dismantling FAG bearings Positioning methods Cylindrical housings, tapered housings, adapter sleeves, push-over sleeves, small bearings can be disassembled using pullers or combinations of metal sleeves and hammers. When using a puller to remove FAG bearings need to pay attention to what matters?
1. When pulling out the bearing, keep the lead screw that is pulled right in line with the center of the shaft, do not touch the thread on the shaft, the shaft diameter and the shaft shoulder;
2. Put the brass ball on the head when loading the puller. When the pull is started, the movement should be slow. Do not overemerge too much. There should be no sudden change in the pull plate.
3. The distance between the rods and the length of the rod should be equal to avoid skew and uneven stress.
4. Pull puller's pulling position should be correct. Pull pull should pull straight the inner ring. In order to prevent pull pull off, tie wire can be tied together with wire;
If or in the process of bearing disassembly, while using a conventional puller can not be disassembled Xi'an FAG bearings , because the pressure fit is too tight, excessive corrosion, bearings and shafts have been melted into one, what are the solutions to such problems?
1, choose a larger type of puller
2. It is recommended to use a puller with a wide opening width that is 50% larger than the outside diameter of the bearing.
3, try to hit the bearing, then pull
4, use anti-rust oil penetration, and then quickly pull
5, mildly heated bearings (be careful not to damage the shaft), then express drawing
6, using hot oil pouring (less than 150 degrees), and then quickly pull
