What is the reason for the damage of the rolling bearing of the high-pressure roots blower?

As the high-voltage roots blower is allowed to operate continuously for a long time, the temperature of the motor itself will rise too high. And if the filling and vegetable grease of rolling bearing are not in place, the rolling bearing oil will be reduced until the rolling bearing is damaged. Then, what is the reason for the damage of the rolling bearing of the high-pressure roots blower?

What is the reason for the damage of the rolling bearing of the high-pressure roots blower?

1. The bearing assembly is not reasonable. If the shaft is damaged due to uneven knocking on the inner ring of the bearing during cold assembly, the interference between the inner ring of the bearing and the outside will be lost or reduced, which will lead to the inner hole running. If the motor end cover is installed, uneven knocking will lead to the loose matching between the bearing chamber of the bearing end cover and the outside of the shaft, which will lead to the outer hole running. Running the inner hole or going to the outer side several times will also cause the temperature rise of the rolling bearing to rise sharply. As long as the rolling bearing is intact, the condition of allowing intermittent running to the outer side will exist.

2. The bearing wall of rolling bearing is not cleaned up, or it is too dirty to add vegetable grease. When the rolling bearing slides to damage during operation, the rolling bearing will be damaged if the temperature rises too high.

3. The rolling bearing is replaced again for production and processing. After the motor end cover is embedded, the interference is large or the ovality exceeds the standard, which causes the bearing ball side clearance to be too small or uneven, which causes the sliding friction of the rolling bearing to increase during operation, and the ambient temperature rises sharply until it is damaged.

4. Due to radial displacement of stator and motor rotor cores or insufficient precision after re machining the transmission shaft, the inner and outer sides of the rolling bearing are not on the same cross section, resulting in high temperature until damage after the rolling bearing runs "hard to eat".

5. Because different types of vegetable oils are mixed, the rolling bearing is damaged.

6. The rolling bearing itself has product quality problems, such as swallow tail guide rail rust, insensitive rotation, too small side clearance, ball bearing deformation, etc.

7. The standby mobile phone has not been operated for a long time, the quality of vegetable oil has changed, and the rolling bearing has been rusted. The maintenance and repair must be carried out on a regular basis and the same well-known brand of vegetable oil must be replaced regularly.
