Abstract
The utility model relates to a bearing which can rotate with zero friction. The bearing is only provided with an outer shaft sleeve and an inner shaft sleeve which are both composed of magnets. Both poles of each magnet are respectively arranged on an inner cylindrical surface and an outer cylindrical surface of each shaft sleeve, and the inner cylindrical surface of the outer shaft sleeve and the outer cylindrical surface of the inner shaft sleeve are provided with magnetic poles with the same magnetism. Thus, with the principle of homopolar repulsion, the inner and the outer shaft sleeves can not contact each other to form a magnetic suspension state, and the friction produced by a general mechanical bearing in rotation is eliminated.
Description
The utility model relates to a kind of friction-free mechanical bearing.
At present, the common mechanical bearing mainly is made up of external axle sleeve, internal axle sleeve and ball (roller) three parts, and ball (roller) contacts with external axle sleeve, internal axle sleeve between external axle sleeve and internal axle sleeve.Be subjected to the frictional resistance between ball (or roller) and external axle sleeve and the internal axle sleeve when rotating like this.
The purpose of this utility model provides a kind of new-type bearing, and it only is made up of external axle sleeve and internal axle sleeve two-part, according to the like pole principle of repelling each other, exterior and interior axle sleeves is all made magnet, thereby exterior and interior axle sleeves does not contact mutually, forms magnetic suspension, eliminates the frictional resistance when rotating.
The purpose of this utility model is achieved in that this bearing external axle sleeve and internal axle sleeve all make the column garden ring magnet with magnetic, and the outer garden cylinder of column garden ring magnet is a utmost point of magnet, and interior garden cylinder is made another utmost point of magnet.The magnetic pole that again design bearing is become the outer garden cylinder of the interior garden cylinder of external axle sleeve and internal axle sleeve to have same magnetic.Because like pole repels each other, can not be in contact with one another between the external axle sleeve of bearing and the internal axle sleeve like this.There is a slight gap in middle meeting, in fact is in magnetic suspension state, thereby has eliminated the frictional resistance when rotating.
Owing to adopt such scheme, because of being in contact with one another the frictional resistance of generation, and mechanical efficiency is improved greatly when having eliminated bearing and rotating.
The utility model is described in further detail below in conjunction with accompanying drawing and example
Fig. 1 is a structure principle chart of the present utility model
Among the figure 1, external axle sleeve 2, internal axle sleeve
Because the like pole principle of repelling each other makes to have the gap between external axle sleeve and the internal axle sleeve forever, can not be in contact with one another and produce friction between external axle sleeve in Fig. 1 (1) and the internal axle sleeve (2), in fact be in magnetic suspension state, so the frictional resistance when having eliminated rotation.
Claims (1)
- A kind of friction-free magnetic suspension bearing, it only is made up of external axle sleeve and internal axle sleeve two-part, it is characterized in that external axle sleeve and internal axle sleeve all are the magnet with column garden annular, the magnetic pole of column garden ring magnet is respectively on the cylinder of inside and outside garden, and the magnetic pole of the outer garden cylinder of the interior garden cylinder of external axle sleeve and internal axle sleeve with same magnetic.
