Small local bearing raceways and rolling elements may be damaged. Operation, local damage due to operation or installation errors. Across the damaged bearing component generates a specific vibration frequency. Vibration frequency analysis can identify the damaged components of cylindrical roller bearings. The vibration behavior of the application properties that in many applications, the same stiffness and rigidity of the structure around the bearing. Because of this feature, as long as the correct choice of bearing (including preload and clearance) and their configuration in the application, it is possible to reduce the application of vibration.
INA bearings rolling bearing itself does not produce noise. Noise in fact is generally felt bearing INA bearing directly or indirectly generate a sound effect and vibration of the surrounding structure.
The number of its load bearing rolling elements in the operation will be a slight change, which is why a lot of the time noise problems can be considered to involve the entire Cylindrical Roller Bearings vibration problems. Exciting when a radial load due to load changes in the number of rolling elements produced at the time of a load bearing. The resulting vibration is occurring but can not be prevented by the axial pre-load to reduce load at all rolling elements.
Bearing ring shape may be deformed adjacent parts mate. If the situation waviness deformation member between the bearing ring and the bearing or shaft appears under tight fit. Operation may produce vibration. Therefore, the bearing and the shaft machined to the required tolerance is very important.
Contact fatigue failure means INA bearing surface by alternating the role of stress arising from failure. Contact fatigue spalling occurred in the bearing surface, often accompanied by fatigue crack, the first maximum alternating shear stress generated at the contact surface of the following, and then extended to the surface of different flake shapes, such as punctate pitting corrosion or pitting, spalling, peel into small pieces called superficial peeling.
Wear failure refers to the relative sliding friction between the surface of the work surface of the metal lead to constant wear and tear resulting from failure. Continuous bearing parts wear will cause gradual damage, and eventually lead to the dimensional accuracy of cylindrical roller bearing loss and other related issues. Wear may affect the change in shape, with the gap increasing and working surface morphology changes that may affect the lubricant or pollution to the extent that it caused a complete loss of lubrication, thus making cylindrical roller bearings as well as the loss of rotational accuracy can not operate normally . Wear failure is one of the various types of bearing common failure mode, press wear is usually divided into the most common form of abrasive wear and adhesive wear.
1. Is the inner ring rotating load when used together with cylindrical roller bearing outer ring properly when running track radial load.
2. The inner and outer rings are tilted relative to the deflection axis of the larger running track, running track roller pavement, resulting in shading at the exit of the load in its longitudinal lap, running track is inclined, double row tapered roller bearing inner ring rotates.
3. Expresses its burden of running track radial load only when the outer ring. L represents the axial load only when the track by. When the inner and outer rings relative inclination big bear only the case of radial load, which deviate from the running track at two orbital plane 180. Location (m).
