Abstract

The invention discloses a non-contact bearing dynamic pressure supporting device and a manufacturing method thereof. The device is characterized by comprising a shaft core, a shaft end turbofan, a permanent magnet rotor and stator part, and a convection end turbofan, wherein the surface of the shaft core is precisely machined; the shaft end turbofan is installed at one end of the shaft core; the permanent magnet rotor and stator component is installed in the middle of the shaft core so as to ensure driving rotation power; and the convection end turbofan is installed at the other end of the shaft core. Any external pressure supply is not needed, and the higher the rotating speed is, the larger the pressure is; the design of large inlet area and high pressure intensity and small outlet area and small pressure intensity is adopted, and the whole device is supported and lubricated in an air suspension mode; and the working condition of a traditional bearing in a severe environment is avoided, so that the product can be used for a long time, and is excellent product equipment with zero friction, zero material consumption, ultra-high-speed operation and long-term operation.

Description

technical field [0001] The invention relates to a supporting device, in particular to a non-contact bearing dynamic pressure supporting device and a manufacturing method thereof. Background technique [0002] Nowadays, the high-speed blower rotation or miniature wind rotation of home appliances in society are all composed of the shaft, bearing, wire winding power and fan blades. Because of the high speed, the self-grinding and friction service life of its bearings is shortened, and there are also adverse environmental effects such as rising operating temperature, external dust, wind, sand, foreign objects, etc., generally losing its life soon. Elimination needs to be updated and replaced, or accidents may occur, resulting in faults such as jamming, damage, and blade injury; plus the damage to the bearing caused by the use environment such as cold and hot wind and dust in the middle of use. Ultra-high-speed wind rotation refers to wind rotation at speeds above 5,000 to 700,0...
