DK28 diesel engine accessories introduction to Marine bearings

The essence of Marine diesel engine parts support is to bear radial loads. It can also be understood as something used to fix the shaft. Includes a bearing block that holds the shaft in place for rotation and controls axial and radial motion. Without bearings, the motor cannot work. Because the shaft may work in any direction, but the motor only needs the shaft to rotate when it works.

Bearings for high speed shafts require good lubrication. Although some bearings are already lubricated by themselves, most bearings require lubricating oil. When running at high speed, it not only increases energy consumption due to friction, but also easily damages the bearing. It is one-sided to transform sliding friction into rolling friction. Because of the plain bearings. Marine bearings also have high requirements for lathes. High precision spraying maintenance technology.

Intermediate bearing is a kind of bearing widely used in mechanical equipment. The intermediate bearing is the main support unit of the ship shaft system, and the working load is large. The working performance of the intermediate bearing directly affects the dynamic performance of the Marine propulsion system. Therefore, the lubrication performance of the intermediate bearing is analyzed, the lubrication of the bearing is effectively predicted, and the bearing structure parameters are optimized according to the design requirements and analysis results to reduce the friction resistance of the intermediate bearing, reduce the vibration and noise of the shaft system, and improve the transmission efficiency and reliability of the shaft system.
