The model utility content
The utility model promptly be to exist in the present oil-containing fan since pad and cushion rubber in the process of fan rotation because the defective that fan working life is short, noise is big that wears out and cause; Provide a kind of magnetic material that adopts that the rotating shaft of fan is attracted, thereby overcome the fan of above-mentioned defective.
The mentality of designing of the utility model is at traditional oil-containing fan; Comprise on the basis of DC fan and ac fan; Original pad and rubber ring between endoporus and rotating shaft removed, set up the adsorption piece of being processed by magnetic material at the other end of rotating shaft, countershaft produces suction; Avoid fans deviating from rotary course, and prolonged the working life of fan.
Specifically, the described oil-containing fan with magnetic absorption of the utility model is characterized in that: described fan comprises flabellum and the fan housing that is positioned at the flabellum periphery; The rotating shaft of metal material is positioned at the flabellum center, and the middle part of fan housing is provided with center pillar, and the center of center pillar is an endoporus; Rotating shaft is inserted in the endoporus; Be full of lubricant oil in the hole between rotating shaft and the endoporus, the rotating shaft top end is set up a magnetic part in endoporus, and there is rubber stopper the center pillar bottom over against the opening filling of endoporus.
Described oil-containing fan with magnetic absorption is characterized in that: also be provided with near the position of magnetic part in the said rotating shaft and be used to increase and the attract each other platform of power of magnetic part.Described platform plays the effect that increases the magnetic attraction area, prevents fan under the situation of high speed rotating, and that possibly cause deviates from.
Described oil-containing fan with magnetic absorption, it is characterized in that: described platform is processed by magnetic material, and the one side polarity that platform and magnetic part are relative is opposite.
Described oil-containing fan with magnetic absorption, it is characterized in that: described platform is processed by metallic material.
Described metallic material can be that iron, cobalt, nickel are processed, or contained their alloy.
Described oil-containing fan with magnetic absorption is characterized in that: said rotating shaft contacts with magnetic part or at a distance of certain distance, the distance of institute's distance is wanted to guarantee enough suction certainly.
Described oil-containing fan with magnetic absorption, it is characterized in that: the top that said rotating shaft contacts with magnetic part is the plane or has an arc shaped surface.The area of contact of arc shaped surface is little, magnetic force slightly a little less than, but the friction of rotation is littler, noise is lower, and can also increase magnetic adsorptive power through increasing platform.
The described oil-containing fan with magnetic absorption of the utility model has following advantage:
1, on the basis of traditional oil-containing fan; Original pad and rubber ring between endoporus and rotating shaft removed; Avoided fan in the process of long-term high speed rotating, because the aging powder that causes of pad and rubber ring falls into the big defective of noise that causes in the endoporus;
2, improved the working life of fan significantly; Owing to adopt magnetic material to adsorb; Prolonged the working life of fan; Existing conventional fan general working life is 20000 hours under 25 ℃ condition, and can reach 48000 hours the working life of the described fan of the utility model;
3, make simply, with low cost, be easy to promote.
