What is self-lubricating bearing
Self-lubricating bearings are divided into composite material self-lubricating bearings, solid inset self-lubricating bearings, bimetal material self-lubricating bearings, special material self-lubricating bearings. According to different uses and working conditions, different self-lubricating bearings are selected. One big category of solid inlaid self-lubricating bearings is a kind of novel lubricating bearings with both the characteristics of metal bearings and oil-free lubricating bearings. The metal matrix bears the load, and the special formula of solid lubricating materials acts as lubrication.
Features of self-lubricating bearings
1. No oil lubrication or less oil lubrication, can be used in no maintenance or less maintenance.
2. Good wear resistance, small friction coefficient and long service life.
3. There is an appropriate amount of elastoplastic, can distribute the stress on a wider contact surface, improve the bearing capacity.
4. The static and dynamic friction coefficient is close, so as to ensure the working accuracy of the machine.
5. The machine can reduce vibration, reduce noise, prevent pollution, improve working conditions.
6. Transfer film can be formed during operation to protect the grinding shaft.
7. The hardness requirement of grinding shaft is low, thus reducing the processing difficulty of related parts.
8. Thin wall structure, light weight, can reduce the mechanical volume.
9. The back of steel can be electroplated with a variety of metals, can be used in corrosive media; It has been widely used in sliding parts of various machines.
Special production process of self - lubricating bearings
Due to the requirements of special production technology, some key equipment in industrial and mining enterprises are running under extremely bad working conditions. Due to the heavy equipment, high temperature, dust or air containing acid corrosion in gas CO, SO2, etc., bring many problems of equipment lubrication, friction and wear serious, most of the domestic enterprises is still using the traditional oil, grease, and the fact that the industrial and mining condition is beyond the scope of oil, grease, easily happened bearing and other friction pair of bite or bite dead, Causes serious parts wear and damage, often leading to equipment outage.
In order to run the production continuously, a large number of maintenance personnel must be invested in addition to the installation of several equipment on the original design. It seriously restricts the increase of productivity, and the consumption of spare parts and energy is great, which has become an important obstacle to the development of production. Automobile manufacturing, cement production, petrochemical and other enterprises have put forward the requirements of providing special lubricating materials under complex working conditions.
Therefore, the research on the inlaid self-lubricating composite material has highlighted its own characteristics in the material formulation and preparation process, and the material properties have reached the international advanced level, which has solved the lubrication problem under special working conditions for enterprises and brought obvious economic and social benefits. However, due to a variety of reasons, more domestic enterprises have not adopted the above situation still exists.
