Check the bearings in the operation of the failure and treatment methods

In the process of using imported bearings, we may encounter some problems, especially in dealing with imported bearings rolling sound, vibration, lubrication and temperature of the state, these problems should be how to find and solve, Xiaobian today and everyone to share experience.
We first from the imported bearings of the vibration, rolling and temperature of the three aspects to talk about the role of lubrication in the bearing is relatively large, so as a separate chapter we will start to explain:
The first is to check the vibration of imported bearings in the work
From the peeling, indentation, corrosion, cracks, wear, etc. will be reflected in the vibration measurement of imported bearings, bearing vibration on the bearing damage is very sensitive, so by using a special imported bearing vibration measuring device (frequency analysis Etc.) can measure the size of the vibration, through the frequency can not be inferred from the specific circumstances of the exception. Since the measured values are different depending on the conditions of use of the bearings or the position of the sensor installation, it is necessary to determine the judgment criteria after analyzing and comparing the measured values of each machine in advance.
Followed by checking the sound of imported bearings when rolling
Because the bearing even if there is a slight divestiture damage, but also issued an abnormal sound and irregular sound, so the sound can be used to distinguish, the use of sound, the operation of the imported bearings rolling sound size and sound quality to check , Play the role of early prevention.
The last is to check the temperature of the imported bearings
If the use of oil hole can directly measure the bearing outer ring temperature, the more appropriate. Under normal circumstances, the temperature of imported bearings, generally based on imported bearing outside the room temperature can be speculated. If the lubrication, the installation of appropriate, the bearing temperature will rise sharply, there will be abnormal high temperature, then must stop running, take the necessary precautions. Usually, the temperature of the imported bearings starts to rise slowly as the operation begins, reaching a steady state after 1-2 hours. The normal temperature of the imported bearings varies with the heat capacity, heat dissipation, speed and load of the machine. If necessary, the use of thermal sensors can monitor the operating temperature of the bearing at any time, and to achieve the temperature exceeds the specified value automatically alarm the police or stop to prevent the occurrence of the shaft accident.
On the operation of imported bearings encountered in the temperature, sound and vibration first mentioned here, I hope to have a little help to my friends.
