The relationship between the life of the automobile water pump bearing and the load it receives

The life of the automobile water pump bearing is closely related to the load, and the load is related to the unbalanced amount of the rotating component.

Through the test of the WR3258152 automobile water pump bearing, the influence of the unbalance of the fan and pulley eccentricity on the load and life of the automobile water pump bearing is studied. It is calculated that the eccentricity of the pulley and the fan will cause the radial load of the rolling elements on both sides of the automobile water pump bearing to fluctuate greatly, and the service life will be reduced accordingly.

At present, the automobile has been widely used as a means of transportation. It is not difficult to buy a car, but it is difficult to buy a good one. Cars of the same brand will be divided into different models and price points. In addition to the engine, there are also automobile water pump bearings that affect the price of automobiles. The role played by the car's integrity is not to be underestimated.

The development of automobile water pump bearings has promoted the development of the automobile industry. At the beginning, the automobile water pump bearings of many automobile manufacturers have complicated structures, many links, and low efficiency. With the advancement of science and technology, this batch of water pump bearings has been phased out, because these bearings are not conducive to the work of automobile water pumps, and the heat dissipation area is also reduced, which greatly reduces the heat dissipation performance of the car. Gradually, more reasonable prices, simpler structures, and higher efficiency automotive water pump bearings came into being, which promoted the development of the automotive industry. Small automotive water pump bearings are inestimable to the development value of the automotive industry.

When installing the water pump bearing, it is necessary to apply equal pressure on the circumference of the end face of the ferrule, and then press the ferrule in. In order to avoid damaging the bearing, be careful not to directly knock the end face of the bearing with tools such as 鎯头.

       In the process of installing the water pump bearing, there is a small amount of interference, we can use the sleeve to press the end surface of the bearing ring at room temperature, use the head to beat the sleeve, and then use the sleeve to hold the sleeve. The ring is pressed in evenly. When pressing in, it is necessary to ensure that the end face of the outer ring of the bearing and the end face of the shell shoulder are pressed tightly, and the end face of the inner ring of the water pump bearing and the end face of the shaft shoulder should also be pressed tightly without any gap. If you need to install in large quantities, you can use a hydraulic press.
