The main performance is as follows: the inner ring has changed color, indicating that the bearing is too hot. The main reasons are as follows:

1. No oiling, the grease will cause high temperature damage to the bearing, the bearing dry grinding, the outer ring, the ball, the cage and the inner ring will be rubbed hard, resulting in an increase in temperature.

2. If the bearing housing has a cooling water jacket, there may be a phenomenon that the cooling water is blocked and the bearing box is exposed to high temperature for a long time.

Therefore, we should regularly check and regularly update new grease.

How to prevent the oil pump shaft and bearing from locking? The specific operations are as follows:

1. Assembly process:

1 Measuring the journal, and matching the bearing of the measured gap combination grid;

2 According to the bearing type and matching clearance requirements, choose the appropriate bearing assembly method;

3 adjust the assembly clearance according to the bearing type;

4 According to the technical requirements of the bearing housing, adjust the bearing compression clearance and end clearance, add lubricating oil or grease as required.

2, the use of links:

1 on-time inspection, record the vibration, temperature and sound of the bearing, there is an increase and abnormal trend, that is, need to pay attention to, check the bearing;

2Qualification and oil change on demand to ensure the quality of lubrication;

3 According to the service life of the bearing, the equipment should be overhauled regularly, and the wearing parts such as bearings should be replaced;

4 Before the start of the car, the car will be parked for a long time.
