High-temperature-resistance abrasion-resistance nanometer bearing fan

Abstract

The invention provides a high-temperature-resistance abrasion-resistance nanometer bearing fan, which comprises a fan frame of a fan, wherein the fan frame of the fan is positioned at the bottom, a case is positioned at the upper part of the fan frame of the fan, a plurality of fan blades are in annular staggered distribution in a way of surrounding the case, an annular magnetic sheet is arranged in the case in a tight pasting way, multilayer silicon steel sheets are arranged in the magnetic sheet and are overlapped, coils are wound on the silicon steel sheets, the silicon steel sheets are annularly distributed in the magnetic sheet, in addition, nanometer bearings are placed in the centers of the silicon steel sheets, a motor rotating shaft is positioned in the nanometer bearings, a circuit board is connected with the coils wound on the silicon steel sheets, further, the nanometer bearings comprise outer rings and inner rings, the inner rings are in two discontinuous annular structures: an upper annular structure and a lower annular structure, the middle is an accommodating cavity, oil storage cotton is arranged in the accommodating cavity, and the outer rings and the inner rings are made of nanometer materials. The high-temperature-resistance abrasion-resistance nanometer bearing fan has the advantages that the high-temperature-resistance and abrasion-resistance capability is high, the service life is greatly prolonged, and wide application prospects are realized.

Description

technical field [0001] The application of the present invention relates to a fan, especially a nano-material bearing, which has the effects of high temperature resistance and wear resistance, and belongs to the technical field of fan equipment. Background technique [0002] Bearing is a component that fixes and reduces the friction coefficient of the load during the mechanical transmission process. When other parts move relative to each other on the shaft, it is used to reduce the friction coefficient during the power transmission process and keep the center of the shaft fixed. , are widely used in mechanical equipment. [0003] Most of the existing bearing materials are steel, including bearing steel, carbon steel and stainless steel. Although steel bearings have the characteristics of good toughness, strong impact resistance and large bearing capacity, they are not resistant to wear and are easily damaged. Oxidation corrosion, not resistant to high temperature. There are...

AI Technical Summary

Problems solved by technology

Oil-impregnated bearings are sleeve bearings that use sliding friction. Lubricating oil is used as a lubricant and drag reducer. In the initial use, the operating noise is low and the manufacturing cost is also low. However, this kind of bearing wears seriously, and its service life is far behind that of ball bearings. Moreover, if this kind of bearing is used for a long time, due to the reason of the oil seal, the lubricating oil will gradually volatilize, and the dust will also enter the bearing, which will cause problems such as slow fan speed and increased noise. In serious cases, the fan will be eccentric due to bearing wear. Violent vibrations are caused, and these phenomena appear, either open the oil seal to refuel, or buy a new fan; the ball bearing has good operation stability, but the price is also high. The above-mentioned defects of the existing bearings limit the service life of the fan.
