What are the classifications of sliding bearings
Author:admin Date:2022-04-15
Sliding bearings are bearings that work under sliding friction. Sliding bearings work smoothly, reliably and without noise.
Sliding bearings are bearings that work under sliding friction. Sliding bearings work smoothly, reliably and without noise. Under liquid lubrication conditions, the sliding surfaces are separated by self lubricating bearing oil without direct contact, which can greatly reduce friction loss and surface wear, and the oil film also has a certain vibration-absorbing ability. But the starting friction resistance is large. The part of the shaft supported by the bearing is called the journal, and the part that matches the journal is called the bearing bush. In order to improve the friction properties of the bearing surface, the layer of anti-friction material cast on its inner surface is called a bearing lining. The materials of the bearing shell and bearing bush are collectively referred to as sliding bearing materials. Sliding bearing applications are generally under high-speed and light-load conditions.
1. According to the direction that can bear the load, it can be divided into two categories: radial (radial) sliding bearing and thrust (axial) sliding bearing.
2. According to the type of lubricant, it can be divided into 7 categories: oil-lubricated bearings, grease-lubricated bearings, water-lubricated bearings, gas bearings, solid-lubricated bearings, magnetic fluid bearings and electromagnetic bearings.
3. According to the thickness of the lubricating film, it can be divided into two categories: thin film lubricated bearings and thick film lubricated bearings.
4. According to the bearing material, it can be divided into bronze bearings, cast iron bearings, plastic bearings, gemstone bearings, powder metallurgy bearings, self-lubricating bearings and oil-impregnated bearings.
5. According to the bearing pad structure, it can be divided into round bearings, elliptical bearings, three oil wedge bearings, stepped bearings, tilting pad bearings and foil bearings.
