Cylindrical Roller Bearing Maintenance

What is cylindrical roller bearing
Cylindrical roller bearings refer to the cylindrical roller and raceway for the line contact bearings.
Characteristics of cylindrical roller bearings
1. Roller and raceway for line contact or repair line contact, radial bearing capacity is large, suitable for bearing heavy load and impact load.
2. The processing requirements of the shaft or seat hole are high. The relative deviation of the outer ring axis should be strictly controlled after the installation of the bearing to avoid the concentration of contact stress.
3. The inner or outer ring can be separated for easy installation and disassembly.
4. Cylindrical roller bearing raceway and rolling body are in geometric shape.

Cylindrical roller bearing maintenance
1. The disassembly of cylindrical roller bearings is regularly maintained and carried out when the bearings are replaced.
After disassembly, if it continues to be used, or if the state of the bearing needs to be checked, the disassembly should be carried out as carefully as the installation.Pay attention not to damage the parts of the bearing, especially the disassembly of interference fit bearing, which is difficult to operate.It is also very important to design and make disassembly tools according to needs.During disassembly, the disassembly method and sequence should be studied according to the drawings and the matching conditions of bearings should be investigated in order to obtain the foolproof disassembly operation.To remove the outer ring of interference fit, set several screws for extruding the screw of the outer ring on the circumference of the shell in advance. Tighten the screw equally at the same time and remove it at the same time.These screw holes are usually covered with blind plugs, tapered roller bearings, etc. Separate bearings. Several notches are set on the shoulder of the enclosure, which are removed by a pad, by a press, or by gentle tapping.The disassembly of the inner ring can be pulled out with a press.At this point, pay attention to let the inner ring bear its pull force.Moreover, the drawing fixtures shown are mostly used. No matter what kind of fixtures, they must be firmly clamped to the side of the inner ring.For this reason, it is necessary to consider the size of the shaft shoulder retaining, or study the processing of the upper groove at the shoulder retaining, so as to use the drawing fixture.The inner ring of large bearing is disassembled by oil pressure method.The oil pressure is arranged in the oil hole of the bearing to make it easy to pull.Bearings with large width can be disassembled by oil pressure method and drawing fixtures.The inner ring of cylindrical roller bearings can be disassembled by induction heating.In a short time to heat the local, so that the inner ring expansion after the drawing method.Induction heating is also used when a large number of such bearing inner rings need to be installed.
2.Cylindrical roller bearing cleaning.When the bearing is removed for inspection, the appearance of the bearing should be recorded by photography and other methods.In addition, it is necessary to confirm the amount of residual lubricant and sample the lubricant before cleaning the bearing.The cleaning of bearings is divided into rough cleaning and fine cleaning, and metal mesh frame can be placed at the bottom of the container in use.Rough cleaning, in the oil with a brush to remove grease or adhesion.At this point, if the bearing is rotated in oil, pay attention to the damage to the rolling surface due to foreign bodies.When fine cleaning, slowly turn the bearing in the oil and carefully carry out.The cleaning agent is usually neutral without water diesel oil or kerosene, according to the need sometimes also use warm lye, etc.Whatever cleaning agent you use, filter it frequently to keep it clean.After cleaning, the bearing should be coated with anti-rust oil or anti-rust grease immediately.
