1. The first is based on deep groove ball rolling sound to be identified and checked
We can use the sound measuring device, the running of the deep groove ball bearing rolling sound size and sound quality to be checked. Because deep groove ball bearings even slight damage such as stripping, will issue abnormal sound and irregular sound, so with the sound sensor can be resolved, play a role in the prevention in advance.
2. The next deep groove ball bearings in the work of vibration to identify the inspection
Deep groove ball bearing vibration on the bearing damage is very sensitive. Such as flaking, indentation, corrosion, cracks, wear and tear will be reflected in the deep groove ball bearings vibration measurement, so, by using a special deep groove ball bearings vibration measuring instrument (frequency analyzer, etc.) can measure the size of vibration , Can not be inferred through the frequency of abnormal points of the specific circumstances. The measured values differ depending on the conditions of use of the bearings or the mounting positions of the sensors. Therefore, it is necessary to determine and compare the measurement values of each machine beforehand.
3. Finally, according to the deep groove ball bearings to check the temperature
Deep groove ball bearing temperature, generally based on deep groove ball bearing room outside the temperature can be inferred, if the use of oil hole can directly measure the bearing outer ring temperature, the more appropriate.
Generally, the temperature of the deep groove ball bearing gradually increases with the start of operation, and reaches a steady state after 1-2 hours. The normal temperature of deep groove ball bearings varies with the heat capacity, heat dissipation, speed and load of the machine. If the lubrication, the installation of the appropriate, the bearing temperature will rise abruptly, there will be unusually high temperature, then must stop running, take the necessary preventive measures. According to a large number of test data, Table 4-1 lists the various machinery in the bearing outer ring when the average temperature for reference. Since the temperature is affected by lubrication, speed, load, and environment, the values in the table represent only the approximate temperature range. The use of thermal sensors can always monitor the bearing temperature, and to achieve the temperature exceeds the specified value automatically alarm the user or stop to prevent burning shaft accident.
