Description
Technical field:
The utility model relates to technical field of bearings, specifically a kind of full permanent magnetism full magnetic suspension bearing.
Background technique:
People generally believe, roller is the requisite constituent element of bearing, but the inside and outside raceway of the roller of iron and steel and iron and steel must need oiling agent to carry out antirust and lubricated, noly know the needs that bearing still can not meet the brisk rotation of people and support, current people close the positive effect of filling magnetic suspension to field of bearings gradually, and many model utility persons also attempt maglev theory to be applied to technical field of bearings.
A kind of magnetic repulsion suspension bearing of Chinese patent unit (patent No.: 201410016545.1), discontinuous construction of the present utility model is by internal magnetic ring and outer magnetic ring, and interior magnetic cylinder and outer magnetic cylinder two pairs of magnets are formed, internal magnetic ring and outer magnetic ring composition magnet ring are to, interior magnetic cylinder and outer magnetic cylinder composition magnetic cylinder pair.Interior magnetic cylinder and axle are fixed, its external diameter is less than the internal diameter of outer magnetic cylinder, two magnetic cylinder adjacent surfaces are same polarity, owing to being that radial radiation magnetizes, homopolar-repulsion is installed, and natural centering under magnetic repulsion effect, plays radial location effect, maintain very little certain interval between inside and outside magnetic cylinder, make axle radially state of suspension.Adopt two groups of discontinuous constructions to be arranged on a support, two play axially locating effect to the magnet ring axially installed to producing repulsion respectively; The internal orifice dimension of outer magnetic ring is a bit larger tham the diameter of axle, and internal magnetic ring is fixed on axle, keeps very little gap between two magnet rings, makes axle be axial suspension state.Magnetic cylinder pair and magnet ring between be also provided with auxiliary bearing, during normal mounting, auxiliary bearing and support or auxiliary bearing and axle have certain interval, also be the radial activity side-play amount of axle, but the radial activity side-play amount of axle is less than the gap of two radial magnetic cylinders, prevent axle when being subject to radial impact power, inside and outside two magnetic cylinders produce and mutually produce fire by friction, and even explode; In fact, auxiliary bearing plays radial position limitation protection effect, makes the radial activity side-play amount of axle be less than gap between interior magnetic cylinder and outer magnetic cylinder.But the bearing unit structure irregularity that this patented technology relates to, needs to carry out correction to existing product and could apply this bearing unit, and this patented technology still applies roller as an one important constituent element, is difficult to some defects avoiding existing bearing.In addition, this patented technology just rests on theory stage, and in actual application, the magnet of a full circle shape is difficult to make, and therefore the actual application prospect of this patented technology is troubling.
Model utility content:
For solving the problem, the following technological scheme that the utility model adopts realizes.
A kind of full permanent magnetism full magnetic suspension bearing, mainly comprise inner sleeve and overcoat, described inner sleeve and overcoat are in a tubular form, described overcoat is enclosed within outside described inner sleeve, be enclosed within above inner sleeve outside described, described inner sleeve periphery two ends are provided with a magnet-fixation grooves, a described magnet-fixation grooves distributes along inner sleeve circumferencial direction, a described magnet-fixation grooves internal fixtion has a magnetic stripe, described overcoat periphery two ends are provided with No. two magnet-fixation grooves, described No. two magnet-fixation grooves distribute along overcoat circumferencial direction, described No. two magnet-fixation grooves internal fixtion have No. two magnetic stripes, a described magnetic stripe arctic is outside, the described No. two magnetic stripe arctic are inside, described inner sleeve outside diameter is less than circular diameter 0.5-10mm in overcoat.
As optimal way, described overcoat top is provided with flange, and the tight circumferencial direction of described end face of flange is evenly distributed with fixed hole.
The utility model beneficial effect is: the utility model by fixing the mode of magnetic stripe in inner sleeve and overcoat, thus achieves the effect repelled mutually between overcoat with inner sleeve, makes overcoat along inner sleeve non-contact rotation or inner sleeve along overcoat; In using process, in inner sleeve, a magnetic stripe has upwards active force to No. two magnetic stripes in overcoat, make inner sleeve can support overcoat suspension to rotate, in addition, rotational velocity is faster, and centrifugal force is larger, really achieves full magnetic suspension rotation, non-contact rotation, decrease the contact friction of bearing, extend the working life of bearing.
Accompanying drawing illustrates:
Below in conjunction with accompanying drawing, the utility model is further illustrated.
Fig. 1 is structural representation of the present utility model;
Fig. 2 is stressed schematic diagram between this magnetic stripe and No. two magnetic stripes;
