How do ball bearings work?

A ball bearing is a precise mechanical element that reduces the friction loss by changing the sliding friction between the running shaft and the shaft seat into rolling friction.

How do ball bearings work?

The ball bearing mainly adopts rolling friction, which changes the friction mode of the bearing. This method more effectively reduces the friction between the bearing surfaces, effectively improves the service life of the fan bearing, and thus prolongs the service life of the radiator. . The disadvantage is that the process is more complicated, resulting in increased cost and higher working noise. Generally used in low-load mechanical transmission equipment. Because the bearing area of ball bearings is small, serious mechanical damage is very likely to occur in the case of high-speed operation, so needle roller bearings are often used in heavy-load mechanical transmission to increase the bearing surface, improve mechanical transmission efficiency and reduce mechanical injury.

What are the reasons for the widespread use of ball bearings?

(1). Significant energy saving. Due to the characteristics of the ball bearing's own motion, its friction force is much smaller than that of the sliding bearing, which can reduce the power consumption of friction resistance, so the energy saving effect is remarkable. From theoretical analysis and production practice, general small ball mills with rolling bearings as main bearings save electricity by 30%~35%, medium ball mills by 15%~20%, and large ball mills by 10%~20%. Since the ball mill itself is a large energy consumer in production, this will mean a considerable savings.

(2). Easy maintenance and reliable quality. The use of ball bearings can eliminate a series of complex and technically demanding maintenance processes such as material smelting, casting and scraping, as well as oil supply, water supply and cooling systems, so the maintenance amount is greatly reduced. Moreover, since the ball bearings are manufactured by professional manufacturers, the quality is often guaranteed. It also brings convenience to the manufacturer of the ball mill.

What are the advantages of using ball bearings?

1. The friction resistance of the ball bearing is small, the power consumption is small, the mechanical efficiency is high, and it is easy to start;

2. The size of the ball bearing is standardized, interchangeable, easy to install and disassemble, and easy to maintain;

3. The ball bearing has a compact structure, light weight and reduced axial size;

4. The ball bearing has high precision, large load, small wear and long service life;

5. The ball bearing has the performance of self-aligning;

6. ball bearings are suitable for mass production, with stable and reliable quality and high production efficiency;

7. The transmission friction torque of the ball bearing is much lower than that of the hydrodynamic bearing, so the friction temperature rise and power consumption are lower;

8. The starting friction torque of the ball bearing is only slightly higher than the rotating friction torque.
