| Summary: | In practice, antifriction bearing failure is a major concern in rotating machinery.
When a machine is shut down, economical losses can occurred as a result of
production stoppage. Therefore, it is important to monitor the condition of antifriction
bearings before it causes a serious catastrophic failure.
In this research, antifriction bearing condition will be monitored to identify defect
of bearings. The monitoring will be done using several parameters, such as vibration,
shock pulse, and temperature. These parameters will be simultaneously monitored
until comprehensive result is obtained.
The bearing being tested in this research is a tapered roller bearing. In order to
identify damage on the bearing in a short time, the test is done using an accelerated
test. This technique is done by giving an overload force on the bearing.
The results of the accelerated test demonstrate the increment of vibration level,
shock pulse, and temperature have appeared before the bearing defect appears. The
result of linear spectrum analysis shows there are several characteristic frequencies
appeared when a defect occurred on bearing components. |
