Novel air floatation thrust bearing and manufacturing method thereof

Abstract

The invention discloses a novel air-floating thrust bearing and a manufacturing method thereof, and the novel air-floating thrust bearing comprises a thrust frame, the middle of which is provided with a thrust plate; the two ends of the rotor are sleeved with radial bearings, and one end of the rotor penetrates out and then is connected with the thrust plate; the cooling foils are detachably arranged on the two sides of the thrust plate; the air floating foil is detachably arranged in the inner rings of the two radial bearings; the invention designs the air floating foils which can be sleeved at two ends of the high-speed rotating rotor and are sleeved at radial and axial inner rings, so that a rigid air film on the outer side of the rotor can be effectively manufactured, air floating is realized, friction is reduced, and the rotating speed of the rotor is increased; and the thrust plate rotating at a high speed can be effectively cooled, and the structure is more stable and durable.

Description

technical field [0001] The invention relates to the field of related devices for breeding fans, in particular to a novel air-floating thrust bearing and a manufacturing method thereof. Background technique [0002] Breeding fan refers to the compressor for breeding, which blows air into the breeding area through compressed air to meet the needs of breeding. The so-called compressor is a component in the gas turbine engine that uses high-speed rotating blades to work on the air to increase the air pressure; the compressor The front part of the impeller blade is curved, called the guide wheel, and its function is to introduce the gas into the working impeller without impact to reduce the impact loss of the airflow; the compressor impeller of a small supercharger generally integrates the guide wheel with the working impeller; There is a diffuser at the outlet of the impeller of the compressor, so that the kinetic energy obtained by the gas in the impeller can be converted into ...

AI Technical Summary

Problems solved by technology

[0003] When the internal rotor of the current breeding fan rotates at high speed, the physical contact between the rotor and the radial bearings set at both ends is too large, and the friction is too large. At the same time, because the rotor will vibrate axially when rotating at high speed, the existing The fan cannot effectively limit this axial vibration, so that the rotor cannot further increase the speed. At the same time, the thrust plate will also generate considerable frictional heat. The existing configuration does not cool the thrust plate well. , it is easy to cause equipment damage, which seriously limits the performance of the fan and the efficiency of compressed air blowing
