Description

High temperature and wear resistant nano bearing fan

Technical field

The invention relates to a fan, in particular to a bearing made of nano material, which has the effects of high temperature resistance and wear resistance, and belongs to the technical field of fan equipment.

Background technique

The bearing is a component that fixes and reduces the friction coefficient of the load during the mechanical transmission process. When other components move relative to each other on the shaft, the mechanism for reducing the friction coefficient during power transmission and maintaining the center position of the shaft is fixed. , has a wide range of applications in mechanical equipment.

Most of the materials used in existing bearings are steel, including bearing steel, carbon steel and stainless steel. Although steel bearings have good toughness, strong impact resistance and large bearing capacity, they are not resistant to wear. It is susceptible to oxidative corrosion and is not resistant to high temperatures. There are also ceramic materials, which have the advantages of corrosion resistance, high temperature resistance and friction resistance, but are not resistant to impact and toughness, and cannot load large bearing capacity.

A good fan, in addition to its large air volume and high wind pressure, its own reliability is quite important, of which the bearing used by the fan plays a very important role. Generally, high-speed fans use ball bearings (ba ll bear ing), while ^ 氐 idle fans use s leeve bear ing which is cheaper. The oil-impregnated bearing is a sleeve bearing that uses sliding friction. Lubricating oil is used as a lubricant and a drag reducing agent. In the initial use, the running noise is low and the manufacturing cost is low. However, the bearing is severely worn and the life span is much larger than that of the ball bearing. Moreover, the bearing is used for a long time. Due to the oil seal, the lubricating oil will gradually evaporate, and the dust will also enter the bearing, causing problems such as slower fan speed, increased noise, etc., and serious fan eccentricity due to bearing wear. Inflammatory vibrations occur, and these phenomena occur either by opening the oil seal and refueling, or by eliminating the purchase of a new fan. The ball bearing has good running stability, but the price is also high. The above-mentioned defects of the existing bearings limit the service life of the fan. Summary of the invention

The application of the present invention is directed to the above-mentioned defects existing in the manufacture of a fan, and provides a fan of a nano material bearing, which has high bearing capacity, high temperature resistance, wear resistance and long service life.

There is a ring-shaped magnetic piece inside, and a plurality of silicon steel sheets are stacked in the magnetic piece. The wire is wound on the silicon steel sheet, and is distributed in the magnetic sheet and placed in the center of the magnetic bearing. The motor shaft is located in the nano bearing. The circuit board is connected to a coil wound on a silicon steel sheet.

Further, the nano bearing comprises an outer ring and an inner ring, wherein the inner ring is a discontinuous upper and lower ring structure, the middle part is a receiving cavity, and the storage cavity is provided with oil storage cotton, the outer and inner圏 is made of nano materials.

The silicon steel sheet is also called a silicon steel sheet, and is a ferrosilicon alloy having a very low carbon content. The silicon content is generally 0.5 to 4.3%, and is rolled by heat and cold. The addition of silicon increases the electrical resistivity and maximum magnetic permeability of iron, reduces coercivity, core loss (iron loss) and magnetic aging. It is mainly used to make iron cores of various transformers, motors and generators, depending on the amount of silicon. Can be divided into low silicon and high silicon.
