Everyone has seen bearings, so have you seen oil-free bearings? So do you know the technical principle and production process of oil-free bearings? this
Key technical principles
Inlaid self-lubricating composite material is a new type of extreme pressure-resistant solid lubricating material, which is composed of a metal substrate and a solid lubricant paste embedded in the holes or grooves of the substrate. During the friction process, the metal substrate bears most of the load.
After friction, the solid lubricant in the hole or groove is transferred or reversely transferred 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. As the friction progresses, the embedded solid lubricant is continuously supplied to the friction surface, ensuring good lubrication during long-term operation.
Production Process
Oil-free bearing is a novel lubricating bearing that combines the characteristics of metal bearing and oil-free bearing.
Due to the requirements of the production process, some key equipment of industrial and mining enterprises operate under extremely harsh working conditions. Due to the heavy equipment, high ambient temperature, large dust or acidic corrosive gases CO, SO2, etc. in the air, it brings many problems to the lubrication of the equipment, and the friction and wear are serious.
Up to now, most of the above-mentioned domestic enterprises still use traditional oil and grease lubrication, but in fact these industrial and mining conditions have exceeded the scope of oil and grease lubrication, and it is very easy to bite or bite the bearings and other friction pairs, causing Severe wear and tear of parts often causes equipment outages.
In order to produce continuous operation, in addition to the original design requiring the installation of multiple equipment for round-robin maintenance, a large number of maintenance personnel must also be invested. Seriously restricting the improvement of productivity, spare parts and energy consumption are extremely large, which has become an important obstacle to the development of production.
Automobile manufacturing, cement production, petrochemical and other enterprises have put forward requirements for providing special lubricating materials under complex working conditions. To this end, the research on inlaid self-lubricating composite materials highlights its own characteristics in material formulation and preparation process. The material properties have reached the international advanced level, which solves the lubrication problem under special working conditions for enterprises and brings obvious advantages. economic and social benefits. However, due to various reasons, more domestic enterprises have not adopted it, and the above situation still exists.
Oil-free bearing (SF-1) is a new type of lubricating bearing that combines the characteristics of metal bearing and oil-free bearing.
Widely used in metallurgical continuous casting machines, rolling equipment, mining machinery, ships, steam turbines, water turbines, injection molding machines and equipment production lines.
advantage
Advantages of Oil-Free Bearings As we all know, all machinery must use some kind of bearing to run smoothly.
Oil-free bearing is a novel lubricating bearing that combines the characteristics of metal bearing and oil-free bearing.
It has the characteristics of high bearing capacity, impact resistance, high temperature resistance, strong self-lubricating ability, etc. It is especially suitable for heavy load, low speed, reciprocating or swinging and other occasions that are difficult to lubricate and form an oil film, and it is not afraid of water and other acid erosion. and scour. The majority of users generally reflect that the embedded bearing not only saves oil and energy, but also has a longer working life than ordinary sliding bearings.
Oil-free bearing The product is made of steel plate as the base, sintered spherical bronze powder in the middle layer, and a mixture of PTFE and lead rolled on the surface layer. It has the characteristics of small friction coefficient, wear resistance, corrosion resistance, oil-free self-lubrication and long service life. Using it can reduce costs, reduce noise, and prevent sticking and slipping.
