Engineering machinery bearing bush is a very important transmission component, which is used to support and locate between the inner and outer rings of the bearing and the axial load surface. In engineering machinery, there are many different classification methods of bearing bush, and several classification methods and their characteristics will be introduced below.
- Classification by Material
According to its material, the bearing bush can be divided into several categories, such as copper, aluminum, and steel. Copper bushing is the most common type of bearing bushing because it can provide better wear resistance and convenient manufacturing technology. In addition, aluminum bushing bearings have the advantages of light weight, high strength, and good corrosion resistance; while steel bushings have extremely high strength and wear resistance, and perform particularly well under large loads.
- Classification by Structure
The bearing bush can be divided into unit bearing bush and coupling bush. The unit bearing bush usually consists of a pair of inner and outer shells, making the bearing more stable as a whole; while the coupling bush is mostly used to connect a series of long sleeves, usually connected by a rigid connector in two or more bearing bush assemblies.
- Classification by Use
The bearing bush can also be classified according to its use, such as unloading bush, fastening bush, and self-aligning bush. Among them, the unloading bush is usually installed in the position of the bearing, can withstand large radial loads and a certain number of axial loads; while the fastening bush mainly strengthens the support capacity of the bearing, and is usually installed with nuts and other fixing parts.
In addition, there are other classification methods, such as size and working environment. When selecting bearing bush, we need to consider various factors comprehensively according to specific application requirements to choose suitable products.
