Working principle of slide bearings
Sliding bearings are mechanical elements that support bearing pairs through sliding friction. Its working principle can be simply summarized as follows:
Lubricant: In sliding bearings, lubricants play an important role. They can reduce the friction and wear between the bearing and the shaft, reduce the temperature of the friction surface, and prevent oxidation, corrosion and contaminants from entering the bearing.
Friction: The working principle of sliding bearings is to support the bearing pair through the sliding friction between two planes facing each other. When the bearing is subjected to external force, the friction will balance the external force and keep the bearing running stably.
Pressure distribution: Sliding bearings will form an oil film on the friction surface through lubricants to reduce the friction coefficient. The formation of this oil film will make the pressure distribution on the bearing uniform and reduce the stress concentration of surface contact.
Temperature control: Sliding bearings will generate a certain amount of heat during operation. The heat generated by the bearing is taken away by conduction, convection and radiation of the lubricant to keep the bearing temperature within an acceptable range.
In general, the working principle of sliding bearings is to rely on lubricants and friction to support the bearings. Suitable lubricants and appropriate working conditions can ensure the normal operation of sliding bearings and improve their service life and work efficiency.
