1. Production process
Because of the requirements of the production process, some key equipment of the industrial and mining enterprises are operating under extremely harsh conditions. Because of the heavy equipment and high ambient temperature, large dust dry bearings or acidic corrosive gases such as CO and SO2 in the air cause many problems in the smoothness of the equipment. The wear of the friction is severe. So far, the above-mentioned companies have large bushing bearings. Some still follow traditional oils and fats, but in fact these working conditions have exceeded the smooth scale of oil and grease, and they easily suffer from bite or bite of bearings and other conflicting pairs, causing severe parts wear and damage. Causes equipment outages on a regular basis. In order to produce a continuous operation, many repairs must be made in addition to the original design that requires the installation of multiple equipment to be repaired. Strictly restraining the improvement of productivity, the spare parts and energy consumption are enormous, and it has become an important obstacle to the development of production. Sliding composite bearing industries, such as car production, cement production, and petrochemicals, have all proposed special smoothing data requirements for the supply of messy working conditions. To this end, the study of inlaid self-smooth composite materials has distinguished itself in data formulation and preparation processes, and the data function has reached the international advanced level. It has solved the problem of smoothness under special working conditions and brought significant The economic and social benefits. However, for many reasons, more domestic enterprises have not chosen, and the above situation still exists.
2. Key technical principles new
The inlaid self-smooth composite material is a new type of extreme pressure resistant solid smooth material consisting of a metallic substrate and a solid smoother paste embedded in the pores or grooves of the substrate. In the conflict process, the metal substrate bears most of the load. Through the collision, the solid smoothing agent in the hole or trough is transported or reversed to the conflict surface, and the solid handling film that is smooth and outstanding, firmly attached and evenly covered on the conflict surface is formed, and the conflict wear is greatly reduced. As the conflict progressed, the embedded solid smoothing agent was continuously supplied to the collision surface, ensuring excellent smoothness during long-term operation.
3. Application and basic functional requirements
SF-2 plus boundary smooth bearing: acid polymethyl aldehyde, has a high wear resistance, the surface of the bearing has an arrangement of the rules of the oil pit with the need to be filled with smooth grease, especially suitable for high load and low speed Rotary motion, shaking motion, and often under load, open and close and not easy to form a fluid smooth part, in the smooth conditions of the gap, can be used for a long time without refueling maintenance, and the process of refueling can make the bearing life time can be More extensions are currently applied to metallurgical machinery, mining machinery, water conservancy machinery, car accessories, construction machinery, and agricultural machinery.
Self-smooth bearing: This product is made of steel plate as the base body, sintered spherical bronze powder in the middle layer, and surface-rolled mixture of polytetrafluoroethylene [ptfe] and lead. It has the characteristics of small conflict coefficient, wear resistance and corrosion resistance, no oil self-smoothness and long service life. It can reduce costs, reduce noise and avoid stickiness and slippage. It is widely used in various mechanical sliding parts such as printing presses, textile machines, hydraulic trucks, tobacco machines, medical machinery, fitness equipment, micro-motors, cars, motorcycles and so on.
Metal base inlaid solid self-smooth bearing: It is a novel and smooth bearing with both metal bearing characteristics and self-smooth bearing characteristics. It is supported by the metal substrate and the specially formulated solid-smooth material has a smooth effect. It has the characteristics of high bearing capacity, impact resistance, high temperature resistance, and strong self-smoothness. Traditional oil bearing: because of its low noise and self-smooth strength, oil bearing has become the new darling of the computer CPU fan bearing, and the market demand is large; in addition, people are increasingly demanding the voice, oil bearing in the The use of everyday household appliances is also expanding.
The basic requirements of the bearing on the material depend to a large extent on the operating function of the bearing. The appropriate choice of material for the production of rolling bearings will have a great influence on their function and life. In general, the primary damage to rolling bearings is fatigue peeling under the effect of alternating stress and loss of bearing accuracy due to frictional wear. In addition, there are cracks, indentations, corrosion and other reasons to form abnormal bearing damage. Therefore, rolling bearings should have high resistance to plastic deformation, low collision wear, outstanding rotation accuracy, excellent dimensional accuracy and stability, and long contact fatigue life. And many of these functions are determined by data and heat treatment processes.
