How many kinds of bearings are there in sliding bearings? What's the function of each?
The shaft supported by the bearing is called the journal, and the part that matches the journal is called the bush. In order to improve the friction properties of the bearing surface, the antifriction material layer, which is cast on its inner surface, is called the bearing lining. Bearing and bearing lining materials are collectively referred to as journal bearing materials. The application of sliding bearings is usually under the condition of high speed and light load.
There are two kinds of clearance, one is the clearance between bearing and bearing bush, the other two is radial clearance of bearing. The first kind of clearance will cause the bearing or bush to be damaged, the lubricant pressure will be reduced, the gap will be too small, the bearing or bearing load will increase sharply, or even burn (tile).The second kind of clearance is too big, the bearing will move back and forth in the radial direction, the whole machine is not stable, the gap is too small, so that the load of the machine increases.Sliding bearings (sliding, bearing) bearings that work under sliding friction. Plain bearings work smoothly, reliably and without noise. Under the condition of liquid lubrication, the sliding surface is separated by the lubricant without direct contact, and the friction loss and surface wear can be greatly reduced. The oil film also has a certain vibration absorption capacity. But the starting friction resistance is larger.

The gap is too small, which will make the bearing or bearing load increase sharply and even burn (tile)The second kind of clearance is too big, the bearing will move back and forth in the radial direction, the whole machine is not stable, the gap is too small, so that the load of the machine increases
