Abstract
The utility model pertaining to bearing art, is a biserial cylindrical roller bearing with dust cap in both sides consisting of an outer ring, an inner ring, conical rollers, a cage and a spacer, both end faces of the bearing outer ring are provided with dust caps, the wall thickness of the outer ring is 3 times of the wall thickness of the outer ring 1 in normal design, the said outer ring can directly act as a supporting working surface. The utility model has the advantages of that, the strength of the outer ring is strengthened, the outer ring can directly act as a supporting working surface, the dust prevention of the bearing is setteled effectively, and with the strengthening of strength of the outer ring, the carrying capacity of the bearing is increased greatly and the service life of the bearing is increased by 50percent.
Description
Technical field
The utility model belongs to technical field of bearings, especially a kind of Biserial cylindrical roller bearing with dust-proof cover.
Background technique
CSP line special bearing, former employing open type double-row conical bearing is because work under bad environment, often there is dust to enter, make the proper functioning of tapered roller bearing be subjected to influence, and bearing outer ring intensity is lower, the short and installation inconvenience of bearing life.
Summary of the invention
The utility model proposes a kind of double-row conical bearing, can effectively prevent entering of dust, can improve bearing reliability and life-span with dust-proof cover.
The technological scheme that its technical problem that solves the utility model adopts is: a kind of double-row conical bearing of two sides band dust-proof cover, form by outer ring 1, inner ring 2, tapered roller 3, retainer 4 and spacer ring 6, bearing outer ring 1 both ends of the surface have dust-proof cover 5, the wall thickness of outer ring 1 is 3 times of normal design outer ring 1 wall thickness, and described outer ring 1 can be directly as the working surface that supports.The beneficial effects of the utility model are, have increased the intensity of outer ring, and the outer ring can effectively solve the dustproof problem of bearing directly as the working surface that supports, and the increase of outer ring intensity has simultaneously strengthened the bearing capacity of bearing greatly, and bearing life improves 50%.
Description of drawings
The utility model is described in further detail below in conjunction with drawings and Examples.
Fig. 1 is a structural representation of the present utility model.
Among the figure: 1, outer ring, 2, inner ring, 3, tapered roller, 4, retainer, 5, dust-proof cover, 6, spacer ring.
Embodiment
This bearing is 1700 medium thin slab continuous casting and rolling line special uses, is a kind of double-row conical bearing of two sides band dust-proof cover.Constituent elements is made up of outer ring 1, inner ring 2, tapered roller 3, retainer 4 and spacer ring 6.The both ends of the surface of bearing outer ring 1 have dust-proof cover 5, can effectively prevent entering of dust, the outer ring wall thickness strengthens, and is 3 times of normal design outer ring wall thickness, has increased the intensity of outer ring, the outer ring can be directly as the working surface that supports, after adopting this design, effectively solved the dustproof problem of bearing, simultaneously the increase of outer ring intensity, strengthened the bearing capacity of bearing greatly, bearing life improves 50%.
