Aero dynamic bearing with metal rubber and elastic chaff composite support structure

Abstract

The invention relates to a radial elastic aero dynamic bearing, in particular to an aero dynamic bearing with a metal rubber and elastic chaff composite support structure. The novel aero bearing with the composite support structure comprises a bearing sleeve, metal rubber blocks, elastic chaffs and a top chaff. The elastic support structure is formed by superimposing the metal rubber blocks and the elastic chaffs. One end of each elastic chaff and one end of the top chaff are fixed on the bearing sleeves, and the other end of each elastic chaff and the other end of the top chaff are free. The metal rubber blocks are formed by metal wire winding and a cold stamping technology, and surrounded and fixed by the elastic chaffs and the bearing sleeve. The elastic chaffs are higher in rigidity and lower in damping, while a metal rubber material is lower in rigidity and high in damping. According to the aero bearing, the elastic support structure of the aero bearing is improved and formed by superimposing the metal rubber blocks and the elastic chaffs, so that the bearing has the characteristic of high rigidity and damping, the carrying capacity of the bearing is improved, the vibration impact is reduced, and the reliability of the bearing is improved.

AI Technical Summary

Benefits of technology

This new design improves how well it works when used on certain types of equipment such as turbines or engines that experience strong movements caused from external forces like winds or impacts during operation. It also has higher stiffness compared to previous designs but still allows for better resistance against damage even if there are more powerful motors involved.

Problems solved by technology

This patented technical problem addressed in this patents relates to improvements on conventional metallic or plasma polymer type air bearors used at extreme conditions (high speeds) without losing their effectiveness over longer periods of operation under severe environmental factors like heat). Specifically, there needs improvement in the design of the spring support system within these types of bearings to increase their durable lifespan and prevent damage from external influences during long hours of service life.
