Disassembly and assembly of automobile water pump bearings

Under the background of the rapid development of the new era, automobiles as the products of the times are also undergoing rapid changes. As the source of power for automobiles, automobile engines are constantly developing toward higher and higher powers to increase the driving speed of automobiles. Under this background, the requirements for automobile water pump bearings have naturally increased. Only the performance of the water pump bearing is strong enough to support the operation of the entire automobile engine and the entire automobile can drive safely on the road. Therefore, in recent years, automobile water pumps Bearings are also constantly being eliminated and updated in development.

First of all, the heat resistance of automobile water pump bearings is getting stronger and stronger in the continuous change and development. As the power of automobile engines continues to increase, the speed of the water pump is also increasing, so the heat generated is also increasing. With high heat resistance, the bearing can continue to work without being affected in a high-heat environment. In addition, the bearing capacity of automotive water pump bearings has also been improved in the long run. Due to the acceleration of the speed, the bearing must have a strong resistance to pressure during operation to effectively complete the work and maintain a longer service life. With the continuous development of the new era, water pump bearings will continue to develop in accordance with new requirements.

Disassembly and assembly of the water pump bearing drag force needs to continue to a certain extent, for example, when installing the bearing, the screw pump needs to stop applying force when the bearing is installed in the correct position to ensure that the end face of the gasket abuts against the end face of the seat hole or the shoulder of the shaft. , Pay attention not to squeeze too tightly or not to fit in place.

As far as possible, the resultant force exerted by the bearing of the disassembly and assembly of the water pump should pass through the axis of the oil-free bearing. For plastic pumps, the force point must be uniform, stable and symmetrical, and the force must be applied through a spherical surface or parallel to the axis. Avoid applying force through the rolling elements, and the force should be uniform and stable, and there should be no impact.

When the bearing is installed, it should be ensured that the drag force continues to the required level, and the use of rolling elements to apply force should be avoided. Ensure that the end face of the washer when installing the bearing abuts against the end face of the seat hole or the shoulder of the shaft, which not only avoids the situation of not being installed in place, but also avoids the situation of being too tight.

   When the bearing diaphragm pump requires the assembly and disassembly of the shaft ring (inner ring), the force needs to be applied through the inner ring, and the force is applied through the outer ring during the assembly and disassembly of the outer ring. When installing the bearing, it is necessary to install the bearing just to the correct position. Stop applying force.
