Abstract
A special shaped bearing with guard edge is composed of external ring, internal ring, roller holder between said internal and external rings, the rollers arranged in said roller holder, and a guard edge connected to external (or internal) ring for increasing the strength and rigidity of external (or internal) ring.
Description
Technical field:
The present invention relates to a kind of bearing, relate in particular to 6700 in the NBS, 6800,6900 serial bearing and deformation bearings thereof.
Background technique:
At present, in instrument, instrument, household electrical appliances, business automation equipment and other special precision detection facility, used bearing majority is 6700,6800,6900 serial bearings in the NBS, they all comprise outer ring, rolling element, retainer and inner ring, rolling element is being evenly distributed under the gripping of retainer between outer ring and the inner ring, this bearing has three kinds of forms: 1. open bearing, i.e. two ends dirt lid all in the air; 2. single face shield bearing, promptly the end at bearing is equipped with dust cover; 3. two-sided shield bearing, promptly two ends at bearing all are provided with dust cover; Described dust cover is located between outer ring and the inner ring.The inner ring of this class bearing and outer ring are slim or ultrathin, and its wall thickness is very thin, has only 0.8～2.5mm.
Bearing is accurate driving component, the requirement on machining accuracy of its inner ring, outer ring is all very high, because the outer ring of this class bearing is very thin, has only 0.8～2.5mm, the intensity of this thin-walled type bearing and rigidity are all very weak, behind shaft strength, the outer ring of bearing and the amount of deformation of inner ring are all very big, hold as 6705 profile shafts, do the time spent bearing the 2kg radial force, its amount of deformation easily makes the shaft strength inequality at 0.03～0.05mm, cause dust cover loosening or come off, can occur when serious that retainer falls apart, rolling element is scattered phenomenon.This class bearing in use, its overall precision of stressed back can swash huge decline, easily makes bearing lose original precision, simultaneously, vibration, noise increase, reliability decrease can't satisfy the supporting requirement of associated host.It is reported, all have the problems referred to above on the similar bearing both at home and abroad, up to the present still do not have the thoroughly way of radical cure, thereby the applying working condition condition of this class bearing is very limited, and can not be extensive use of.
Summary of the invention:
Goal of the invention of the present invention is to provide a kind of special-shaped rib bearing, to overcome many deficiencies that existing thin-wall bearing exists.
Technological scheme of the present invention is:
Special-shaped rib bearing of the present invention, comprise outer ring, rolling element, retainer and inner ring, rolling element is being evenly distributed under the gripping of retainer between inner ring and the outer ring, it is characterized in that: the end at bearing outer ring or inner ring is provided with special-shaped rib, special-shaped rib and bearing inner race or outer ring are connected as a single entity, the radial dimension of special-shaped rib is less than the interior hole dimension of outer ring, greater than the excircle dimension of inner ring.
As to of the present invention perfect, described special-shaped rib and bearing outer ring are connected as a single entity, and are Spielpassung between special-shaped rib and the bearing inner race, also are provided with dust cover at the other end of bearing, and place between bearing inner race and the outer ring.
Owing on the outer ring of bearing or inner ring, be provided with special-shaped rib, can greatly improve the strength and stiffness of bearing outer ring or inner ring like this, thereby integral rigidity of the present invention and running accuracy are increased substantially, can fundamentally overcome many deficiencies that existing similar bearing exists, the amount of deformation after it is stressed can reduce significantly.Contrast after tested, act on the similar bearing of same size with identical radial force, its amount of deformation has only 10% of existing product amount of deformation, as with the bearing of the present invention of 6705 type same sizes, bearing under the effect of 2kg radial force, its amount of deformation has only 0.002mm, and the synthesis precision of this bearing can reach more than the P5 level, simultaneously, the bearing capacity of bearing can improve 50%.
Description of drawings:
Fig. 1 is a kind of structural representation of the present invention;
Fig. 2 is an another kind of structural representation of the present invention;
Among the figure: the 1-outer ring; The 2-rolling element; The 3-retainer; The 4-inner ring; The 5-dust cover; The special-shaped rib of 6-;
Embodiment:
Embodiment 1: special-shaped rib bearing of the present invention, form by outer ring 1, rolling element 2, retainer 3, inner ring 4 and dust cover 5, rolling element 2 is being evenly distributed under the gripping of retainer 3 between inner ring 4 and the outer ring 1, be provided with special-shaped rib 6 with bearing outer ring 1 disjunctor at the right-hand member of bearing outer ring 1, between special-shaped rib 6 and the bearing inner race 4 is Spielpassung, its gap is 0.01～0.15mm, and this bearing is the single face shield bearing; When the distance between special-shaped rib 6 and the bearing inner race 4 during, be open bearing greater than 0.5mm; Make this bearing become two-sided shield bearing, then dust cover 5 should be housed at the other end of bearing, its installation form is identical with existing similar bearing.
Embodiment 2: special-shaped rib bearing of the present invention, form by outer ring 1, rolling element 2, retainer 3, inner ring 4 and dust cover 5, rolling element 2 is being evenly distributed under the gripping of retainer 3 between inner ring 4 and the outer ring 1, be provided with special-shaped rib 6 with bearing inner race 4 disjunctors at the right-hand member of bearing inner race, between special-shaped rib 6 and the bearing outer ring 1 is Spielpassung, its gap is 0.01～0.15mm, and this bearing is the single face shield bearing; When the distance between special-shaped rib 6 and the bearing outer ring 1 during, be open bearing greater than 0.5mm; Make it to become two-sided shield bearing, then dust cover 5 should be housed at the other end of bearing, its installation form is identical with existing similar bearing.
The above-mentioned two routine basic model thin-wall bearings of only lifting can be made various deformation bearings on this basis as required, hold as band locking groove or band stop ring profile shaft.No matter bearing structure how,, all belong to protection scope of the present invention as long as on the outer ring of bearing or inner ring, be provided with special-shaped rib.
