Description
Technical field
The utility model relates to technical field of bearings, specifically a kind of full permanent magnetism magnetic suspension bearing.
Background technique
The kind of bearing is a lot, but be deep groove ball bearing, thrust-bearing or plane bearing all requires that roller and raceway fit tightly, the installation of roller is very inconvenient, in addition, there is contact just to have friction, have friction just to have wearing and tearing, therefore, current bearing has the situation running damping and wearing and tearing, and working life, lifting was obstructed, and motion speed has room for promotion.
A kind of magnetic repulsion suspension bearing of existing Chinese patent unit (patent No.: 201410016545.1), this technological scheme comprises: axle, internal magnetic ring, outer magnetic ring, auxiliary bearing, limiting stopper and support; Install internal magnetic ring at the close end of axle, outer magnetic ring corresponding is with it rack-mount, and two magnet ring adjacent surfaces are same polarity; Axle is equipped with magnetic cylinder in diametrical magnetization, and it is outer and be fixedly mounted on support that the outer magnetic cylinder of diametrical magnetization is sleeved on interior magnetic cylinder, and two magnetic cylinder adjacent surfaces are same polarity, between axle and support, be also provided with auxiliary bearing; Shaft end head is provided with limiting stopper corresponding with it and spacing ball.The rolling element that between axle with support, nothing directly contacts, dependence magnetic repulsion axle is state of suspension, and nothing friction between axle and support, nothing are worn and torn, transmission efficiency is high, and without the need to lowering the temperature and lubricating, long service life, has very high applied value at High Speed Fields such as Aero-Space.But the horizontal and vertical distance of this technological scheme is comparatively large, and structure irregularity, position of bearings need be needed to carry out processing could apply this technological scheme to existing; In addition, this technological scheme carries out the support of bearing only by maglev magnetic, and the inside and outside magnet ring contact when load is heavier, this technological scheme lost efficacy, and caused damage and was difficult to estimate.
Model utility content
The technical problems to be solved in the utility model be to provide a kind ofly be convenient to install, the full permanent magnetism magnetic suspension bearing of one easy to use.
For solving the problems of the technologies described above, the utility model provides a kind of full permanent magnetism magnetic suspension bearing, mainly comprise inner sleeve, along the circumferential direction fixed groove is provided with in the middle of described inner sleeve, described inner sleeve two ends are along the circumferential direction provided with positive stop lug boss, described positive stop lug boss is along the circumferential direction provided with lower raceway, mode by glueing joint in described fixed groove is fixed with arc bar permanent magnet, repulsion permanent magnet is provided with outside described arc bar permanent magnet, described repulsion permanent magnet by glued joint mode and overcoat be connected, inside, described overcoat both sides is provided with bracing ring, described bracing ring internal surface is provided with raceway, in described upper raceway and lower raceway, multiple ball is installed, described ball is fixing by fixing frame circumference.
As optimal way, described ball diameter is less than the circle diameter 1-1.5mm that described upper raceway and lower raceway are formed.
As optimal way, described arc bar permanent magnet and repulsion permanent magnet are all block, and described multiple arc bar permanent magnet is fixed in fixed groove and forms circumferential body shape, and multiple repulsion permanent magnet is fixed on jacket internal and forms cylindrical shape.
The beneficial effects of the utility model are: the utility model structure is simple, and cheap, compound with regular structure, without the need to making any change to existing product, directly can need the place of bearing in existing product by this products application.The principle that the utility model utilizes the repulsion same sex of permanent magnet to repel, make bearing carry out non-contact operation, reduce the operation damping of bearing, bearing wear is little, runs smooth and easy.Ball diameter described in the utility model is less than the circle diameter 1-1.5mm that described upper raceway and lower raceway are formed, and ball size is less, easy for installation, and during use, ball does not stress, and weares and teares less between ball and raceway, bearing long service life; When load is heavier, when arc bar permanent magnet and the repulsive force repelled between permanent magnet are difficult to support, ball and raceway contact support, rolling friction is utilized to run, avoid arc bar permanent magnet and repel permanent magnet direct contact wear, improve arc bar permanent magnet and repel permanent magnet working life.

Embodiment
Below in conjunction with concrete the drawings and specific embodiments, the utility model is described in further detail:
As Figure 1-4, a kind of full permanent magnetism magnetic suspension bearing, mainly comprise inner sleeve 5, described inner sleeve 5 is axially arranged with cylindricality through hole 11, described cylindricality through hole 11 is convenient to that the utility model is a kind of weighs installing and using of permanent magnetism magnetic suspension bearing, fixed groove 8 is along the circumferential direction provided with in the middle of described inner sleeve 5, described inner sleeve 5 two ends are along the circumferential direction provided with positive stop lug boss 9, described positive stop lug boss 9 is along the circumferential direction provided with lower raceway 10, arc bar permanent magnet 4 is fixed with by the mode of glueing joint in described fixed groove 8, be provided with outside described arc bar permanent magnet 4 and repel permanent magnet 3, described repulsion permanent magnet 3 is connected by the mode of glueing joint and overcoat 1, inside, described overcoat 1 both sides is provided with bracing ring 2, described bracing ring 2 internal surface is provided with raceway, in described upper raceway and lower raceway 10, multiple ball 7 is installed, described ball 7 is fixing by fixing frame 6 circumference.Described ball 7 diameter is less than the circle diameter 1-1.5mm that described upper raceway and lower raceway 10 are formed.Ball 7 diameter described in the utility model is less than the circle diameter 1-1.5mm that described upper raceway and lower raceway 10 are formed, ball 7 size is less, easy for installation, and during use, ball 7 does not stress, ball 7 and wear and tear less between upper raceway and lower raceway 10, bearing long service life; When load is heavier, when arc bar permanent magnet 4 and the repulsive force repelled between permanent magnet 3 are difficult to support, ball 7 and upper raceway contact with lower raceway 10 and support, rolling friction is utilized to run, avoid arc bar permanent magnet 4 and repel permanent magnet 3 directly contact wear, improve arc bar permanent magnet 4 and repel permanent magnet 3 working life.
