Abstract
The utility model relates to a self-aligning roller bearing which comprises a bearing outer ring and a bearing inner ring, wherein double rows of rollers and retaining frames thereof are arranged between the bearing inner ring and the bearing outer ring, and an intermediate baffle ring is arranged between the double rows of rollers. The self-aligning roller bearing is characterized in that two sides of the bearing outer ring are respectively provided with a sealing cover, and the sealing cover is used for sealing space between the bearing inner ring and the bearing outer ring. The double rows of rollers are symmetrically distributed. The retaining frames are symmetrically sleeved between the bearing inner ring and the bearing outer ring. The inner surface of the bearing outer ring is a spherical surface, the radian of the inner surface of the bearing outer ring is matched with that of the surfaces of the rollers, double lines of roller tracks are arranged on the outer surface of the bearing inner ring, and surfaces of the roller tracks are matched with surfaces of the rollers in radian. According to the self-aligning roller bearing provided by the utility model, the sealing ring is additionally provided, grease is added in the bearing, so that the bearing is self-lubricated.
Description
Technical field
The utility model relates to a kind of roller bearing, especially a kind of selfaligning roller bearing with selflubricating.
Background technique
Selfaligning roller bearing can bear heavy load and impulsive load; The present normally used selfaligning roller bearing of people, its structure is generally: the bearing outer ring with spherical raceway, the bearing inner race with two raceways; A solid cage; Two row rollers, the rotation of bearing inner race guide ring guiding retainer, and the width of bearing inner race and bearing outer ring is identical.
In prior art, selfaligning roller bearing all is to carry out circulating lubrication through lubricant oil, can't realize selflubricating.
Summary of the invention
The purpose of the utility model is to overcome the deficiency that exists in the existing technology, and a kind of selfaligning roller bearing is provided, and can realize the selflubricating of selfaligning roller bearing.
According to the technological scheme that the utility model provides, said selfaligning roller bearing comprises bearing outer ring and bearing inner race, and the retainer of biserial roller and support rollers is installed between said bearing outer ring and bearing inner race, between said biserial roller, is with guide ring; Characteristic is: the both sides at said bearing outer ring are placed a slice sealing cover respectively, and said sealing cover seals up the space between bearing outer ring and the bearing inner race.
Said biserial roller is symmetrical distribution.Said retainer symmetry is enclosed between bearing inner race and the bearing outer ring.
The internal surface of said bearing outer ring is a sphere, and the surperficial radian of the radian of the internal surface of bearing outer ring and roller is complementary.Outer surface at said bearing inner race is provided with the biserial roller track, and the surperficial radian of the surface of this roller track and roller is complementary.
The described selfaligning roller bearing of the utility model is through adding seal ring, and fatten in bearing makes bearing realize selflubricating.
Description of drawings
Fig. 1 is the structural representation of the utility model.
