Tapered-land thrust pad with elastic supporting structures

Abstract

The invention discloses a tapered-land thrust pad with elastic supporting structures. The tapered-land thrust pad comprises a tapered-land thrust pad body, disc springs, five positioning columns and aretainer, and is characterized in that the five positioning columns are mounted at the geometric center and various corners of the periphery of the retainer, and each disc spring is mounted on the corresponding positioning column; the tapered-land thrust pad body is arranged on the retainer with the positioning columns and the disc springs, and pressure plates are welded on the tapered-land thrust pad body, so that the tapered-land thrust pad with the elastic supporting structures can be formed. The tapered-land thrust pad has the advantages that the tapered-land thrust pad body can be supported by the five disc springs at the center and the periphery of the tapered-land thrust pad body, accordingly the tapered-land thrust pad can be elastically supported and is excellent in uniform-loadperformance; the disc springs at the center and the periphery of the tapered-land thrust pad body are reasonably selectively arranged, and accordingly deformation of the tapered-land thrust pad can becontrolled, the lubrication performance and the use reliability of tapered-land thrust bearings can be improved, and the working lives of the bearings can be prolonged.

Problems solved by technology

[0002] The thrust sliding bearing is lubricated by the dynamic pressure oil film formed between the thrust pad and the mirror plate. The pressure and temperature generated by the oil film on the thrust pad surface will cause the thermal deformation and elastic deformation of the thrust pad; research shows that the appropriate thrust pad convex deformation is conducive to The formation of dynamic lubricating oil film, excessive convex deformation or concave deformation of the thrust pad are not conducive to the formation of dynamic lubricating oil film, the force deformation of the thrust pad on the fixed inclined plane is concave deformation, and the thermal deformation is convex deformation; when the bearing working load is large or the bearing When the size of the thrust pad on the inclined plane is large, it is easy to cause the overall deformation of the thrust pad on the inclined plane to be concave deformation, or the deformation is too small to reach the most suitable slightly convex deformation, resulting in poor lubrication performance of the bearing

The deviation of the axis of the mirror plate of the thrust disc, the dimensional error of the bearing assembly, the vibration of the bearing and other factors will lead to the unbalanced load of the bearing, which will lead to excessive force on individual thrust bearing pads and easy damage, thus affecting the performance of the entire unit

The above problems will reduce the lubrication performance of the bearing, thereby affecting the reliability, safety and working life of the bearing.
