Bearing during operation, there must be sound, temperature, and vibration phenomena. Therefore, for the operation of the bearing maintenance may listen, touch, outlook and bearing fault diagnosis instrument anomalies found bearing the bearing according to the change of status to determine whether in normal working condition.
Sounding to check the size and sound quality of the rolling bearing in operation sound, bearing even a slight peeling or other damage, also making an abnormal sound and the irregular tone, with the measured sound able to distinguish.
Bearing vibration is very sensitive to the damage to the bearing, such as peeling, creasing, corrosion, cracks, wear, etc. will be reflected in bearing vibration measurement, through the use of special bearing vibration measurement (frequency analyzer) to measure the vibration The size of the frequency points can not infer the specific situation of the abnormality. After the measured values due to the conditions of use of the bearing or sensor mounting position, etc. different in advance of each machine measured values were analyzed and compared to determine the criterion.
The wear failure refers to relative sliding friction between the surfaces to lead to its work surface metal constantly wear arising VALID. Continuous wear will cause gradual damage of the bearing parts, and eventually led to the cylindrical roller bearing loss of dimensional accuracy and other related issues. Wear may affect the shape change, with the gap increasing and work surface morphology changes may affect the lubricant or its pollution reaches a certain level and cause lubrication complete loss of function, making the loss of cylindrical roller bearings rotating accuracy even can not operate normally . The Wear Failure is one of the common failure mode of all kinds of bearings, wear form usually can be divided into the most common abrasive wear and adhesive wear.
1. Outer ring running track roller bearings cylindrical inner ring rotating load plus radial load correctly.
2 is the relative inclination of the inner ring and the outer ring, the greater the deflection of the shaft running track, the raceway surface of the running track, in its longitudinal direction to produce shades of the load ring at the outlet of the running track is inclined, a double row tapered roller rotating inner ring bearings.
3 shows the trajectory of the outer ring only burden the radial load. L represents a subject only to the locus of the axial load. In the inner and outer rings relative inclination large bear radial load only when its trajectory deviation from the 180 two track surface. The location
