Metal-based inlaid solid self-lubricating bearing


A novel lubricated bearing that combines the characteristics of a metal bearing with the characteristics of a self-lubricating bearing, is subjected to a load by a metal substrate, and a specially formulated solid lubricating material acts as a lubricant. It has the characteristics of high bearing capacity, impact resistance, high temperature resistance and strong self-lubricating ability. Traditional oil-impregnated bearings: Due to the advantages of low hum and self-lubrication, oil-impregnated bearings have become the new darling of computer CPU fan Tilting pad journal bearing , and the market demand is large. In addition, as people's requirements for voices are getting higher and higher, oil-impregnated bearings are The application of everyday household appliances is also expanding.
The basic requirements of the bearing for the material depend to a large extent on the performance of the bearing. Choosing the right material for the rolling bearing will have a major impact on its performance and longevity. In general, the main form of failure of rolling bearings is fatigue spalling under alternating stress and loss of bearing accuracy due to frictional wear. In addition, there are cracks, indentations, rust and other causes of abnormal damage to the bearing. Therefore, the rolling bearing should have high resistance to plastic deformation, less friction and wear, good rotation accuracy, good dimensional accuracy and stability, and long contact fatigue life. And many of these properties are determined by the combination of materials and heat treatment processes.
