Special attention should be paid to the following points during the use of integral sliding bearing seats:

(1) The use of bearing seat cooling system. When used correctly, the cooling water for the bearing seat not only extends its service life, but also improves production efficiency. The material of the bearing seat is generally made of specialized bearing seat steel through various treatments, and even the best bearing seat steel has its limitations in use, such as temperature. When the bearing seat is in use, if the mold temperature is too high, it is easy to cause early cracks on the surface of the mold core. Some bearing seats even have large areas of cracks before exceeding 2000 mold cycles. Even the mold core of the bearing seat changes color during production due to the high temperature of the bearing seat. After measurement, it even reaches over 400 degrees Celsius. When exposed to the cold state of the release agent at such temperatures, it is easy to develop cracks, and the produced products are also prone to deformation, strain, and mold sticking. When using cooling water for the bearing seat, the use of release agents can be greatly reduced. This way, during the processing of sliding bearing seats, operators will not use release agents to lower the temperature of the bearing seat. The advantage of manufacturers of sliding bearing seats lies in effectively extending the life of the bearing seat, saving die-casting cycles, improving product quality, reducing mold sticking, pulling, and aluminum sticking, and reducing the use of release agents. It can also reduce the loss of the top rod and core caused by overheating of the bearing seat temperature.

(2) During the production process, the bearing seat must be preheated to prevent the occurrence of turtle cracks caused by sudden contact with hot metal liquid in cold bearing seats. For more complex bearing seats, spray lamps and liquefied gas can be used, and for better conditions, mold warmers can be used. For simpler bearing seats, slow injection preheating can be used.

(3) Cleaning the parting surface of the bearing seat is very laborious and easy to overlook. Operators should thoroughly clean the parting surface of the bearing seat with kerosene, which not only prevents the bearing seat from being squeezed, but also opens up the exhaust groove blocked by residual release agent or other dirt on the bearing seat after cleaning, which is conducive to the discharge of gas from the cavity during the injection process and improves product quality.

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.
