Judge bearings will use again, to consider the extent of the damage of bearings, machine performance, importance, operating conditions, such as checking cycle later decided. Check the results, if it is found that the bearing damage and abnormal situation, injury section to find out the causes and countermeasures. In addition, the examination results, if you have the following defects, bearing is not then the need to replace the new bearing hub of Hengding said.
A. inner and outer ring, rolling body holder, in which any cracks and debris.
B. inner and outer ring, rolling body in which any split.
C. raceway surface, rib, rolling card significantly hurt.
D. cage wearing serious or rivets loose badly.
E. rolling body raceway surface, rust and bruises.
F. rolling, rolling a significant indentation and trace.
A creep g. diameter of the inner ring or outer ring outside diameter.
H. powerful thermochromism.
I. sealing grease bearings seals and shields to serious damage.
(1) in operation, inspection and fault handling
In the operation of inspection items of bearing rolling sound, vibration, temperature, lubrication condition, as follows:
A sound, bearing rolling
The sound of the operation of the bearing rolling sound and sound check, bearingI even with minor injuries such as split, abnormal sound and irregular sound issued, by measuring the sound to distinguish.
bearing vibration
Damage to the bearing of bearing vibration very sensitive, such as peeling, indentation, rust, crack, wear will be reflected in the bearing vibration measurement, Hengding hub said through the use of special measuring bearing vibration (frequency analyzer, etc) can measure the vibration of the size, through frequency cannot be inferred from the specific situations of exception. The measured values for different conditions of use of SUNTHAI bearing or sensor installation location, therefore require prior to each machine measurement are analyzed and compared to determine the criteria.
