Self-aligning ball bearing fault detection standard

1. first, it is identified and checked according to the sound of self-aligning ball bearing
We can use the sound detector to check the size and sound quality of the running self-aligning ball bearing rolling sound. Because self-aligning ball bearing, even if there are slight peeling and other injuries, will also produce abnormal sounds and irregular sounds, so it can be used to distinguish with the sound detector, and play an early preventive role.
2. second self-aligning ball bearing in the vibration of the work to identify and check
The vibration of self-aligning ball bearing is very sensitive to the damage of the bearing. For example, peeling, indentation, rust, crack, wear will be reflected in the self-aligning ball bearing, vibration measurement in so, through the use of self-aligning ball bearing vibration measuring device special (frequency analyzer etc) can measure the size of the vibration, the frequency can not be inferred from abnormal situation. The measured values are different due to the conditions of the bearing or the location of the sensors. Therefore, we need to analyze and compare the measured values of each machine beforehand, and then determine the criteria.
3. finally is based on the temperature of self-aligning ball bearing
The temperature of self-aligning ball bearing is generally deduced according to the temperature outside the self-aligning ball bearing chamber. If the oil hole can directly measure the temperature of bearing outer ring, it is more appropriate.
In general, the temperature of self-aligning ball bearing rises slowly with its operation, and reaches a stable state after 1-2 hours. The normal temperature of self-aligning ball bearing varies with the heat capacity of the machine, the amount of heat dissipation, the speed and the load. If the lubrication, install appropriate, bearing temperature quick rise, abnormal high temperature occurs, then you must stop, take the necessary preventive measures. According to a large number of test data, table 4-1 lists the average temperature of the outer ring of the bearing working in various machines for reference. As the temperature is affected by lubrication, speed, load, and environment, the median of the table only indicates a general temperature range. The use of the heat detector can monitor the working temperature of the bearing at any time, and automatically alarm or stop the accident of the burning shaft when the temperature exceeds the specified value.
