Production Process and Principle of Oilless Sliding Bearing

Due to the requirements of production technology, some key equipment of industrial and mining enterprises operate under extremely bad working conditions. Due to the heavy weight of equipment, high ambient temperature, large dust or the presence of acidic corrosive gases such as CO and sulfur dioxide in the air, the lubrication of equipment has caused many problems and severe friction and wear. Up to now, most of the above enterprises in China still use traditional oil and grease lubrication. In fact, these working conditions have gone beyond the scope of oil and grease lubrication, and it is very easy to get bitten or killed by bearings and other friction pairs, It causes serious wear and damage of parts, and often leads to equipment shutdown.

In order to continuously operate the production, in addition to the original design, it is required to install multiple equipment for rotation maintenance, a large number of maintenance personnel must also be invested. It severely restricts the improvement of productivity, and the consumption of spare parts and energy is very high, which has become an important obstacle to the development of production. Automobile manufacturing, cement production, petrochemical and other enterprises have put forward the requirements for providing special lubricating materials under complex working conditions. For this reason, the research on inlaid self-lubricating composite materials has highlighted its own characteristics in terms of material formulation and preparation process, and the material performance has reached the international advanced level, which has solved the lubrication problem under special working conditions for enterprises, and has brought significant economic and social benefits. However, due to various reasons, more and more domestic enterprises have not adopted it, and the above situation still exists.

Embedded self-lubricating composite is a new type of extreme pressure resistant solid lubricating material, which is composed of metal substrate and solid lubricant paste embedded in the hole or groove of the substrate. The metal substrate bears most of the load in the friction process. Through friction, the solid lubricant in the hole or groove transfers or reversely transfers to the friction surface, forming a solid transfer film with good lubrication, firm adhesion and uniform coverage on the friction surface, which greatly reduces friction and wear. With the friction going on, the embedded solid lubricant is continuously provided on the friction surface, ensuring good lubrication during long-term operation.
