Background
The bimetallic bearing is one of oil-free lubrication bearings, and is formed by rolling a copper-steel integrated bimetallic strip which is formed by sintering a lead-tin-bronze alloy on the surface of a high-quality low-carbon steel backing serving as a matrix and sintering and densely rolling the alloy for multiple times, and is suitable for bearing medium-speed and high-impact loads. The product has the advantages of good wear resistance and the like, and various oil grooves, oil holes and oil holes can be processed on the friction surface by a special process means, so that the product is suitable for use under different lubricating conditions.
At present, when the bimetallic bearing is used, enough friction force is generally obtained through the extrusion of the outer diameter of the bimetallic bearing and a bearing seat, so that the bimetallic bearing is prevented from rotating relative to the bearing seat. However, when the rotating shaft starts to rotate in an accelerating manner from zero rotating speed, because an oil film is not formed at the moment, the rotating shaft and the inner diameter of the bimetallic bearing can rub, and the bimetallic bearing and the bearing seat can possibly rotate relatively; in addition, because some bimetallic bearings are thin, when the bimetallic bearings are unevenly pressed with the bearing seat during installation, the roundness ratio of the bearings may be poor, and the rotation of the rotating shaft is further influenced. Therefore, there is a need for an improved structure that overcomes the above-mentioned deficiencies.
