Abstract
The utility model discloses a self-aligning roller bearing, in particular to the self-aligning roller bearing which can adjust the inside clearance, which comprises an inner ring, an outer ring, a holder and a plurality of rollers, wherein pockets are evenly distributed on two sides of the holder, the rollers are spherical rollers and are taken in the long drum shape, two ends are planes, bus bars on the external side faces are taken in the circular arc shape, the external side face is slidingly engaged with the pockets on two sides of the holder, the distance between the external end of a longitudinal center line and the inner ring is less than that between the internal end of the longitudinal center line and the inner ring, thereby an included angle is formed between the longitudinal center lines and shafts of the inner and the outer rings, the outer ring is composed of two piece outer rings, the thickness of the outer end faces of the two piece outer rings is respectively less than the thickness of the inner end faces which are all spherical surfaces and are slidingly engaged with the outer side faces of the rollers and distances are remained. The self-aligning roller bearing has the adjustable inside clearance and long service life.
Description
Technical field
The utility model relates to a kind of roller bearing.Specifically, be the selfaligning roller bearing of adjustable inside play.
Background technique
At present, the various roller bearings that mechanically use all are to be made of inner ring, outer ring, retainer and some rollers.Retainer both sides wherein are evenly equipped with the pocket hole, and the cross-shaped layout in pocket hole of both sides.Roller is a long drum shape, its two ends are circular, its outer side surface is a sphere, be slidingly matched between the pocket hole of its outer side surface and retainer both sides, the outer end of its vertical center line and the spacing between inner ring be less than the inner of its vertical center line and the spacing between inner ring, thus make they vertical center line and inside and outside circle axially between all form angle.Outer ring wherein has only one, this outer ring inner side surface be sphere, its two-end thickness is greater than the thickness in the middle of it so that with roller between be the slip shape and match.Because the outer ring has only one, the inner side surface of this outer ring is a sphere, and its two-end thickness is greater than the thickness in the middle of it, service time one is long, can increase because of wearing and tearing make the inner play of bearing between roller and inside and outside circle, and the play of bearing inside increases, and can produce mechanicalness noise again.For the play that reduces because of bearing inside increases the mechanicalness noise that produces, just need to change roller bearing.Therefore, the working life of this roller bearing is not long.
The model utility content
Problem to be solved in the utility model provides a kind of selfaligning roller bearing.This selfaligning roller bearing, its inner play is adjustable, long service life.
For addressing the above problem, take following technological scheme:
Selfaligning roller bearing of the present utility model is made of inner ring, outer ring, retainer and some rollers, and retainer both sides wherein are evenly equipped with the pocket hole, and the cross-shaped layout in pocket hole of both sides.Roller is a spherical roller, it is long drum shape, its two ends are the plane, the bus of its outer side surface is a circular arc, be slidingly matched between the pocket hole of its outer side surface and retainer both sides, the outer end of its vertical center line and the spacing between inner ring be less than the inner of its vertical center line and the spacing between inner ring, thus make they vertical center line and inside and outside circle axially between all form angle.Be characterized in that said outer ring is made up of two semi outer rings, the exterior edge face thickness of these two semi outer rings is all less than their interior edge face thickness, their inner side surface be sphere and and the outer side surface of roller between be and be slidingly matched, and leave spacing between them.
Take such scheme, have the following advantages:
Because selfaligning roller bearing of the present utility model, its outer ring is made up of two semi outer rings, the exterior edge face thickness of these two semi outer rings is all less than their interior edge face thickness, their inner side surface be sphere and and the outer side surface of roller between be and be slidingly matched, and leave spacing between them.When using a period of time inner play to occur, can eliminate inner play by turning two spacings between semi outer rings down, thereby prolonged the working life of roller bearing.Therefore, the working life of selfaligning roller bearing of the present utility model is longer.
Description of drawings
Accompanying drawing is a selfaligning roller bearing structural representation of the present utility model.
Embodiment
As shown in drawings, selfaligning roller bearing of the present utility model is made of inner ring 2, outer ring, retainer 4 and some rollers 3.Retainer 4 both sides wherein are evenly equipped with axial pocket hole, and the cross-shaped layout in axial pocket hole of both sides.Said roller 3 is a spherical roller, it is long drum shape, its two ends are the plane, the bus of its outer side surface is a circular arc, be between the pocket hole of its outer side surface and retainer 4 both sides and be slidingly matched, the spacing that the outer end of its vertical center line and inner ring are 2 is less than the spacing of 2 of the inner of its vertical center line and inner rings, thus make they vertical center line and inner ring 2, outer ring axially between all form angle.Said outer ring is made up of two semi outer rings 1, and the exterior edge face thickness of these two semi outer rings is all less than their interior edge face thickness, their inner side surface be sphere and and the outer side surface of roller 3 between be and be slidingly matched, and leave spacing between them.By regulating two spacings between the semi outer rings 1, can change the size of the inner play of bearing.Therefore,, bearing inner play long when service time one increases, when producing mechanicalness noise, can eliminate mechanicalness noise by turning two spacings between the semi outer rings 1 down, thereby prolong the working life of roller bearing.
