compound bearing的意思|示意

'

Compound bearing is a kind of bearing which consists of two parts: the inner ring and the outer ring, one of which is mounted directly on the shaft and the other is on the bearing. It is used to bear the radial and axial load, and reduce the frictional resistance, and also maintain the radial orientation.

Compound bearing is widely used in various industrial fields. For example, in the fields of aircraft engines, machine tools, ships, high-speed rail, railway vehicles, automotive, agricultural machinery and other fields, it is used to bear radial and axial loads, maintain radial orientation, and reduce frictional resistance.

In addition, compound bearing has the advantages of low friction, long service life and easy installation. Generally speaking, the structure of the bearing is very simple, with the size of the mounting hole and the bearing surface, which can ensure the cooperation of the bearing and the shaft, and the installation is more convenient.

Moreover, compound bearing can be divided into two types according to its structure: tapered roller bearings and cylindrical roller bearings. Tapered roller bearings are suitable for heavy load and impact load, while cylindrical roller bearings are suitable for bearing high speed and radial load. Therefore, the choice of bearing should be based on the use of the machine, so as to choose the most suitable bearing structure.
