Abstract
The present invention provides an outer locating bearing which comprises bearing body composed of an inner ring, an outer ring, a steel ball, a holder and a dustproof cover. The bearing body can also be not provided with the dustproof cover. An annular groove is arranged in the outer ring. A ring belt on which two and more than two hollow bulges is connected in the annular groove, and the ring belt is matched with the annular groove. The bearing can be directly fixed in a bearing seat without a mould and a tooling clamp; the small spherical surfaces of the hollow bulges on the ring belt enable the bearing seat to be positioned. The present invention has the advantages of simple structure, easy manufacture, low manufacture cost, wide use range, no limitation, good versatility, use convenience and long service life; the outer locating bearing can be used on bearings of different structures.
Description
Technical field
The present invention relates to a kind of bearing, particularly a kind of directly with bearing fixing in bearing support, make bearing location accurately, and the outside fix bearing of easy to use and long service life.
Background technique
General bearing in use, the user must be pressed in the bearing support with mould or with bearing outside diameter, be generally transition or interference fit, if tolerance fit is selected improper or is installed incorrect, the axle center easily produces skew or the play that leaves is diminished or produces interference, bearing moves, rotation is dumb thereby make, and causes the inefficacy of bearing, influences the working life of bearing.
Some user adopts the bonding method of glue, and bearing top circle is bonded and fixed on the bearing support, if misoperation also can make tackiness agent splash in the bearing, directly influences bearing and normally uses.
Number of patent application 02145114.1 " interior locate mode bearing " is just for to overcome the some shortcomings part of above-mentioned existence, and a kind of new structure is provided, and reliability bearing preferably.
But its structure of the bearing of this kind structure is complicated, and is difficult to processing, and the manufacture cost height also need make simultaneously and its supporting use, the bearing support that matches, thereby using scope is little, narrow limitation is big, versatility is poor.
Summary of the invention
Technical problem to be solved by this invention is: provide a kind of outside fix bearing, its simple in structure, easy making, fabricating cost low, can use in the bearing of different structure, and use more convenient, no narrow limitation, versatility is good, can guarantee that bearing normally uses, and long service life.
The present invention addresses the above problem the technological scheme that is adopted: positioning bearing comprises by inner ring, outer ring, steel ball, retainer, dust cover or does not have the bearing support that dust cover constitutes, have annular groove on the described outer ring, and endless belt is housed in annular groove, the little sphere of uniform hollow projection more than two and two is arranged on the described endless belt.
Compared with prior art, the invention has the advantages that: this bead surface elastic body endless belt that is free cardiac prominence to rise is easily made, fabricating cost is low, easily installs, and can directly be enclosed within on the annular groove of outer ring external diameter, do not need mould, frock clamping just can directly put into bearing support, use more convenient, and bearing support no requirement (NR), so using scope is wide, no narrow limitation to being mated, all can use on the bearing of different structure, versatility is good.Because bad at going up the uniform little sphere of hollow projection, when bearing when mounted, the little sphere on the bearing endless belt touches in the bearing support, relies on the pressure that resiliently deformable produced of hollow little sphere, bearing fixing in bearing support.Because the hollow little sphere on the endless belt is uniform contact on bearing support, so shaft strength is even, thereby makes bearing easy to install and use, reliable, has stopped the hidden danger that causes bearing to lose efficacy in advance owing to Bearing Installation is incorrect.
Description of drawings
Fig. 1, structural representation of the present invention.
The structural representation of Fig. 2, endless belt.
The A-A sectional drawing of Fig. 3, Fig. 2.
Embodiment
Below in conjunction with accompanying drawing embodiments of the invention are further described.
Constitute bearing support or do not have dust cover 8 by inner ring 5, outer ring 4, steel ball 6, retainer 7, dust cover 8.
Endless belt 2 bends to the thin slice annular of both ends open by rectangular elastomer, and it is bead face 3 that uniform two and plural hollow projection are arranged on the outer surface of endless belt.The peak of the height of projection of bead face 3 should exceed the depth H of bearing outside diameter or annular groove 1.
Have annular groove 1 in the middle of the outer ring 4, and a depth H of annular groove 1, be greater than the thickness δ of twice endless belt, i.e. H＞2 δ.
During use, endless belt 2 is installed in the annular groove 1 on 4 peripheries of bearing support outer ring, and then directly put into bearing support (figure draw), bead face 3 by the highest point on the inwall compressing endless belt 2 of bearing support makes its downward flattening, is out of shape, extends, also constantly regulates, two ends up to endless belt 2 is closed up, till the staggered again overlapping together, at this moment the bearing support inwall supports the location by endless belt, reaches the purpose of interference fit.
Claims (4)
1, a kind of outside fix bearing, comprise by inner ring (5), outer ring (4), steel ball (6), retainer (7), dust cover (8) or do not have the bearing support that dust cover constitutes, it is characterized in that: have annular groove (1) on described outer ring (4), and endless belt (2) is housed in annular groove (1), the little sphere (3) of uniform hollow projection more than two and two is arranged on the described endless belt (2).
2, bearing according to claim 1 is characterized in that endless belt (2) is bent to the thin slice annular of both ends open by rectangular elastomer.
3, bearing according to claim 1 is characterized in that the depth H of annular groove (1) is greater than the thickness δ of twice endless belt (2).
4, bearing according to claim 1 is characterized in that the peak of little sphere (3) height of projection should exceed the depth H of the external diameter or the annular groove (1) of bearing outer ring (4).
