Tips for repairing abnormalities in water pump rolling bearings

The engine of the automobile center is developing in the direction of high power and high power, so higher performance requirements are put forward for automobile water pumps, such as higher heat resistance, greater load-bearing ability, and good sealing performance. However, the editor of automobile water pump bearings will give you a detailed introduction to the varieties of automobile water pump bearings and the device structure of water pump bearings of different models:

Classification of automobile water pump shaft bearings:

Water pump bearings in ordinary automobiles include deep groove ball bearings, cylindrical roller bearings, etc., with bearings with single and double seals, and open bearings with sealed installations.

Device structure of water pump bearings for different models of automobiles:

In light vehicles, commercial vehicles, and car water pumps, the water pump bearing adopts a water pump shaft-connected unit structure, which is compact in structure, comes with a seal, and is convenient to install. The outer ring is a double row integral type, and the inner ring is a water pump shaft. There are multiple combinations of double-row balls, single-row balls and needle rollers, single-row balls and cylindrical rollers.

Tips for repairing abnormal water pump rolling bearings

1) The ordinary average service life of rolling bearings is about 5000h. If they are used for a long time or the device is improperly maintained, the bearings will be destroyed. If it is found that there are cracks in the inner and outer rings of the rolling bearing, the ball is broken, and the gap between the ball and the inner and outer rings is measured with a feeler gauge of 03mm beyond the rules, the bearing should be replaced with a new one.

2) If the inner ring is tight or the rotation is not sensitive enough, it may be due to the deformation and distortion of the holding frame of the rolling ball and the friction of the bearing ring. At this time, the holding frame can be quietly hit with a hand hammer to correct the deformed part.

3) If there is rust on the surface, it can be wiped off with fine sandpaper, and then washed and dried.

4) The pump shaft and the inner ring of the bearing are tightly matched. The press-in method is generally used, and the heating method can be used if it is difficult.
