Analysis On Disassembly Skills Of Fag Bearing

Analysis On Disassembly 

The disassembly of fag bearing shall be carried out with the same care as the installation. Pay attention not to damage fag bearings and parts, Analysis On Disassembly especially the disassembly of interference fit fag bearings, which is difficult to operate.

Therefore, in the design stage, it is necessary to consider the convenience of disassembly in Analysis On Disassembly advance, and it is also very important to design and manufacture disassembly tools according to needs.

During disassembly, the disassembly method and sequence shall be studied according to the drawings, and the matching conditions of fag Analysis On Disassembly bearings shall be investigated, so as to ensure the safe disassembly operation.

1. Removal of outer ring

Remove the outer ring of the interference fit. Set several outer ring extrusion screws on the circumference of the shell in advance. Tighten the screws equally while removing. These screw holes are usually covered with blind plugs, tapered roller bearings and other separated fag bearings. Several cuts are set on the housing shoulder. Use cushion blocks, disassemble with a press or knock gently.

2. Disassembly of cylindrical bore bearing

The inner ring can be easily removed by pressure machinery. At this time, Analysis On Disassembly pay attention to make the inner ring bear its pulling force.

The inner ring of large fag bearing is disassembled by oil pressure method. Oil pressure is applied through the oil hole arranged on the shaft to make it easy to pull out. The fag bearing with large width is disassembled by the Analysis On Disassembly combination of oil pressure method and drawing fixture.

The inner ring of Nu and NJ cylindrical roller bearings can be disassembled Analysis On Disassembly by induction heating. It is a method of drawing after heating part in a short time to expand the inner ring.

3. Disassembly of tapered bore bearing

Disassemble the relatively small fag bearing with fixed sleeve, support the inner ring with the stop fastened on the shaft, turn the nut back several Analysis On Disassembly times, and knock it with a cushion block and a hammer for disassembly.

For large fag bearing

it is easier to disassemble by oil pressure. Pressurize and send oil in the oil hole on the taper hole shaft to expand the inner ring and disassemble fag bearing. During Analysis On Disassembly operation, FAG bearing may come out suddenly. It is better to use the nut as a stop.

Maintenance and judgment of SKF Bearing: in order to judge whether the disassembled bearing can be used, it shall be checked after the bearing is cleaned. Check the state of raceway surface, rolling surface and mating surface, wear of cage, increase of SKF Bearing Clearance and damage irrelevant to the decline of dimensional accuracy.

For non separable small ball bearing, support the inner ring horizontally with one hand and rotate the outer ring to confirm whether it is smooth. Tapered roller bearing and split SKF Bearing can inspect the raceway surface of rolling element and outer ring respectively.

Since large SKF bearings cannot be rotated by hand, pay attention to the appearance of rolling elements, raceway surfaces, cages, edge retaining surfaces, etc. the higher the importance of SKF bearings, the more careful the inspection is.

Cleaning of SKF Bearing: when disassembling the lower bearing for maintenance, first record the appearance of SKF Bearing, confirm the residual amount of lubricant, and wash SKF Bearing after sampling the lubricant for inspection.

As a cleaning agent, gasoline and kerosene are commonly used. The SKF Bearing removed shall be cleaned in coarse cleaning and fine cleaning. They shall be placed in the container respectively, and the metal mesh pad shall be placed at the bottom first, so that the bearing will not directly contact the dirt of the container.

During rough cleaning, if SKF Bearing rotates with dirt, it will damage the rolling surface of the bearing, which should be paid attention to. In the coarse cleaning oil, use a brush to remove the grease and adhesion. After it is roughly clean, turn to fine cleaning. Fine cleaning is to carefully clean the SKF Bearing while rotating in the cleaning oil. In addition, the cleaning oil should also be kept clean.
