Radial sliding bearing seat

One of the main functions of bearings in machinery is to support the rotating body, reduce the friction coefficient during its motion, and ensure its rotational accuracy. Bearings can be divided into various types such as sliding bearings, rolling bearings, joint bearings, deep groove ball bearings, angular contact ball bearings, self-aligning ball bearings, seat bearings, and combination bearings.

Maintenance of bearings:

The lubrication methods for radial sliding bearing seats are divided into grease lubrication and oil lubrication. Special attention should be paid to the amount of lubrication, whether it is oil lubrication or grease lubrication. Insufficient lubrication with too little amount will affect the bearing life, while too much amount will generate large resistance and affect the speed. The bearing clearance should be appropriate. If the generator set is too large, it will cause impact, while if it is too small, it will result in poor lubrication and may burn the bearings. The disassembly of bearings is a regular maintenance and is carried out during bearing replacement.

feature

Strong bearing capacity: It operates well under high-speed and heavy load conditions. When using liquid friction sliding bearings, the internal friction force in the fluid replaces the friction force on the metal surface, which can effectively avoid wear and prolong the service life. It is suitable for equipment such as rolling mills, hydro generators, etc. that can withstand huge impact and vibration loads or extremely heavy loads.

High operating accuracy: stable operation, no noise, can ensure precise support position. When the liquid friction bearing is designed reasonably and used correctly, it can achieve high rotational accuracy. It is commonly used in equipment such as precision grinders that require particularly precise support position for shafts.

Good buffering and damping: The oil film on the working surface of liquid friction sliding bearings has the functions of vibration reduction, buffering, and noise reduction, which can effectively absorb vibration and reduce impact. It is suitable for occasions such as automotive engines that require buffering of vibration and impact.

Small radial size: suitable for situations where the shaft is densely packed or the diameter of shaft type rotating parts is small, it has advantages when the radial size is limited, such as multi roll rolling mills and other equipment.

There are various structural forms, including integral, sectional, and self-aligning structures. The integral structure is simple and cost-effective, but the clearance cannot be adjusted after the shaft sleeve wears out, making it inconvenient to assemble and disassemble. It is suitable for low-speed, light load, or intermittent mechanical work; Split type assembly and disassembly are convenient, and it is easy to adjust the bearing clearance after bearing wear, making it widely used; The self-aligning type can adapt to the deformation of the shaft, ensure good contact between the shaft neck and the bearing shell, and is used in situations where the shaft neck is long, the main shaft stiffness is small, or the two bearings are difficult to align.

application field

In the industrial field, it is widely used in metallurgy, mining, transportation systems, environmental protection equipment and other industrial scenarios. For example, rolling mills in the metallurgical industry require sliding bearing seats to withstand enormous rolling forces and impact loads; Sliding bearing seats are also commonly used in crushers and conveyor systems in mines to adapt to harsh working environments and heavy load requirements.

In the field of electric power, sliding bearing seats are used to support rotors, reduce friction and wear, and ensure smooth operation of equipment such as water turbines and generator sets in hydropower stations. The hydroelectric generator of the Three Gorges Dam adopts high-performance sliding bearing seats for its rotor bearings to ensure long-term stable operation under enormous hydraulic forces.

In the field of transportation, sliding bearing seats are used in the traction motors and bearings of railway locomotives, which can work well under high-speed and heavy load conditions, ensuring the safe operation of trains. In addition, sliding bearing seats are also used in the crankshaft bearings and other parts of some car engines to improve the performance and reliability of the engine.

In the field of mechanical processing, high-precision machining equipment such as precision grinders and boring machines require extremely high precision for shaft support. The high precision and stability of sliding bearing seats can meet the needs of these equipment and ensure machining accuracy.
