The manufacturing principle of bearings

Bearings are common mechanical parts widely used in various mechanical equipment. Its work is used to support and reduce the friction loss of machine components, so that the machine runs smoothly. As a result,

What is the manufacturing principle of bearings?

The production principle of bearings mainly includes three aspects: material selection, processing technology and lubrication methods.

1. Material selection

Bearing material selection has a significant impact on its performance and life. In general, the inner and outer rings and rolling elements of bearings are usually made of high-strength and high-hardness steel, such as GCr15.

Cages are usually made of materials such as copper alloys or engineering plastics to improve the wear and corrosion resistance of bearings. In addition, according to different working conditions and requirements, you can also choose

It has special materials, such as ceramic, plastic, stainless steel and so on.

2, processing technology

The processing technology of bearings mainly includes forging, heat treatment, precision machining and assembly. First, the inner and outer rings and rolling elements of the bearing are forged into their original shape; Then, after heat treatment, improve its hardness and strength, while improving the internal structure; Next, through precision machining, the size and shape of the bearing and the inner and outer rings of the rolling are precisely realized

Require; Finally, the inner and outer rings, rolling elements and cages are assembled together using an assembly process to form a complete orientation.

3. Lubrication method

The lubrication methods of bearings are mainly divided into dry friction lubrication and liquid lubrication. Dry friction lubrication refers to the self-lubrication of the material directly used in the working process of the bearing without the need to add lubricant sliding properties, such as ceramic bearings and plastic bearings. Liquid lubrication refers to the operation of bearings during this process, by adding liquids such as lubricating oil or grease, reducing friction loss and wear, and long service life of bearings. Liquid lubrication can be divided into two types: oil lubrication and grease lubrication; According to different working conditions and requirements, choose the appropriate lubrication method. The production principle of bearings mainly includes three aspects: material selection, processing technology and lubrication methods. Reasonable selection of bearing materials, appropriate processing technology, with reasonable lubrication methods; It can provide good performance and service life for bearings. At the same time, the design and selection of bearings in practical applications should meet the requirements according to the specific working conditions and requirements, and the mechanical equipment with the same demand. Through continuous research and innovation, the manufacturing principle of bearings will not continue to improve and perfect, to provide more reliable and efficient mechanical equipment support for various industries.
