Description

Technical Field

[0001] The utility model relates to the technical field of sliding bearings, in particular to a sliding bearing for a gear box. Background Art

[0002] 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 lubricating oil without direct contact, which can greatly reduce friction loss and surface wear. The oil film also has a certain vibration absorption ability. However, the starting friction resistance is relatively 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. The layer of anti-friction material cast on the inner surface of the bearing to improve the friction properties of the bearing surface is called the bearing liner. The materials of the bearing liner and the bearing liner are collectively called sliding bearing materials. Sliding bearings are generally used under low-speed and heavy-load conditions, or in operating parts that are difficult to maintain and add lubricating oil.
