IKO cylindrical roller bearing common abnormal damage solution principle

1) If there is a rhythmic knocking or percussion sound during the operation of the IKO bearing, it may be caused by the peeling of the raceway of the cylindrical roller bearing, the indentation, or improper installation of other parts;
2) It is found that the IKO bearing has a "small, sturdy" sound, which may be caused by the tight seal of the bearing, the oil is not clean, and the bearing clearance is too large;
3) It is found that the bearing has a squeaking sound of “吱咛, 吱咛”, which may be caused by dryness of the lubricant or lack of lubricant;
4) If the bearing is found to have the sound of “shashasha”, it may be that the cylindrical roller bearing is not cleaned, and the interior is mixed with debris, sand, dust and other debris;
5) The inner ring of the bearing is overheated by heat, and the bearing and the seal are rubbed with the relevant parts;
6) When installing IKO bearings, the bearings are deformed by tapping bearings or other parts;
7) The tightening sleeve of the bearing is too tight or loose;
8) The size of the bearing housing is too large (including the use of large), causing the IKO bearing outer ring to rotate in the bearing housing...etc., etc., it is possible to make the bearing produce noise and abnormal sound. The cause of the vibration of the cylindrical roller bearing is basically the same as the cause of the bearing noise and abnormal sound, and there is a strong correlation between the two. However, the vibration frequency that is not in the audio range will not cause noise and abnormal sound.
The rolling noise of the bearing and its control method The rolling sound is the harsh metal friction sound that can occur in cylindrical roller bearings in all occasions. Most of them occur in the larger type of grease-lubricated bearings, and the lubrication of the base oil deteriorates. It is more likely to occur in fat and hardly occurs when oil is lubricated. In addition, it is more likely to occur in winter. When subjected to pure radial load, it is easy to occur in the case of large radial clearance, and it is easy to occur in a certain speed range depending on the size of the model, and it will occur continuously. It will appear intermittently. Special processing methods for the outer ring raceway can prevent the occurrence of rolling noise. If necessary, use this kind of high temperature bearing, or reduce the radial clearance of the bearing properly, use the excellent grease and improve the matching with the cylindrical roller bearing. The rigidity of the machine.
 (1) Select low-noise bearings; this depends on the purchase of high-quality cylindrical roller bearings, generally good IKO bearings are made of high-material steel, with high density, high resistance;
 (2) From the application of the bearing to try to eliminate the noise, is to add grease on the link, must choose the lubrication material, can play twice the result with half the effort;
 (3) Avoid resonance with the host and avoid resonance sensitive speed; this point requires professional installation and debugging to avoid resonance problems;
 (4) If other methods are not effective, take additional measures for sound insulation and noise reduction, install some sound control equipment, and so on.
