Bearing in operation in the failure and treatment

Update:2017-12-27

The company is located in:
In the process of using imported bearings, we may encounter some problems, especially in the processing of imported bearings rolling sound, vibration, lubrication and temperature of the state, these problems should be how to find and solve today and we share a piece of experience.
We start with the vibration of the imported bearings, rolling and temperature of the three aspects to talk about:
The first is to check the vibration of the imported bearings in the work
From peeling, indentation, corrosion, cracking, abrasion etc. Vibration Measurement bearings are reflected in the view of the vibration bearings bearing damage is very sensitive, therefore, the use of special bearings by measuring vibration (frequency analysis Etc.) can measure the size of the vibration, through the frequency of points can not infer the specific circumstances of the anomaly. Since the measured values differ depending on bearing conditions or sensor mounting positions, etc., the measured values of each machine must be analyzed and compared beforehand to determine the judgment criteria.
Followed by the inspection of imported bearings rolling sound situation
Because the bearings even with minor damage such as peeling, an abnormal tone will sound irregular, can therefore be used to distinguish sound measuring device, using sound measuring device, the rolling bearing operation sound inlet size and quality checks performed , Play a preventive role in advance.
The last is to check the temperature of the bearing rotation
If the use of oil hole can be measured directly bearing outer ring temperature, the more appropriate bit. Under normal circumstances, the temperature of imported bearings, generally based on the temperature outside the inlet bearing chamber can be speculated out. If the lubrication, the mounting section is appropriate, the bearing temperature will rise sharply, there will be abnormal high temperature, then you must stop running, take the necessary precautions. Normally, the temperature of the imported bearings gradually rises with the start of operation and reaches a steady state after 1-2 hours. The normal temperature of imported bearings due to the heat capacity of the machine, heat dissipation, speed and load different. When necessary, the use of thermal sensors can monitor bearing temperature at any time, and to achieve the temperature exceeds the specified alarm or stop automatically when the fire shaft to prevent accidents.
