Description

High-temperature-resistant wear-resistant sliding bearing

Technical Field

The utility model relates to the technical field of sliding bearings, in particular to a high-temperature-resistant and wear-resistant sliding bearing.

Background

Plain bearings, bearings that operate under sliding friction. The sliding bearing works stably and reliably without noise. Under the condition of liquid lubrication, the sliding surface is separated by lubricating oil without direct contact, the friction loss and the surface abrasion can be greatly reduced, and the oil film also has certain vibration absorption capacity. But the starting frictional resistance is large. The portion of the shaft supported by the bearing is called the journal, and the part that mates with the journal is called the bearing shell. The layer of antifriction material cast on the inner surface of the bearing shell in order to improve its frictional properties is referred to as the bearing lining. The materials of the bearing shell and the bearing liner are collectively referred to as sliding bearing materials. Sliding bearing applications are typically under high speed, light load conditions.

When the conventional sliding bearing is used for a long time, the sliding bearing is easy to wear, and simultaneously, accumulated heat can be released in a harmless manner, so that the service life of the bearing is influenced. Therefore, there is a need for an improved structure to overcome the above-mentioned drawbacks.
