Abstract
The utility model discloses a double-row angular contact bearing with a flange. The double-row angular contact bearing comprises an outer ring assembly, an inner ring, rolling bodies and holding frames, wherein the outer ring assembly comprises a first outer ring, an outer ring spacer and a second outer ring, the first outer ring is provided with a flange plate, the outer ring spacer is arranged between the first outer ring and the second outer ring, the outer ring spacer is evenly provided with a plurality of oil injection holes which penetrate through from up to down, roller path positions of the first outer ring and the second outer ring are respectively provided with a holding frame, rolling bodies are arranged inside pocket holes of the holding frames, and the rolling bodies are matched with the two roller ways of the inner ring. Therefore, the double-row angular contact bearing with the flange can remove axial play of the bearing and prolong service life.
Description
Technical field
The utility model relates to technical field of bearings, particularly relates to a kind of flanged (FLGD) biserial angular contact bearing.
Background technique
The biserial angular contact bearing is mainly used in high-accuracy CNC machinery, precision tool machine, industrial machine, electric mechanical, conveying mechanism, aerospace industry etc. and requires on highi degree of accuracy, the high-revolving ball screw.
Existing ball screw bearing, owing to need to bear larger radial load and thrust load, the general form that adopts the pairing bearing, namely adopting two covers or the above wrapping angle of two covers is that 60 ° the mode of bearing by pairing combines, what use was maximum at present is back-to-back matching form, and its load that can bear and carrying moment are maximum, and have preferably rigidity, can bear tilting moment, axially locating is best.But it more or less has certain axial internal clearance, and the installation precision of bearing is low, directly has influence on stability, noise and the precision of machinery integral, thereby affects the working life of bearing.
The model utility content
The technical problem that the utility model mainly solves provides a kind of flanged (FLGD) biserial angular contact bearing, can eliminate the axial internal clearance of bearing, increases the service life.
For solving the problems of the technologies described above, the technological scheme that the utility model adopts is: a kind of flanged (FLGD) biserial angular contact bearing is provided, comprise: outer coil assembly, inner ring, rolling element and retainer, described outer coil assembly comprises the first outer ring, outer ring spacer and the second outer ring, described the first outer ring is with flange plate, described outer ring spacer is arranged at the centre of described the first outer ring and described the second outer ring, and evenly be provided with some oil holes that run through up and down on the described outer ring spacer, the raceway place of described the first outer ring and described the second outer ring is equipped with retainer, be provided with rolling element in the pocket hole of described retainer, described rolling element matches with two raceways of described inner ring respectively.
In preferred embodiment of the utility model, the wrapping angle of described biserial angular contact bearing is 45 ° or 60 °.
In preferred embodiment of the utility model, also be provided with seal ring between described inner ring and the described outer coil assembly.
In preferred embodiment of the utility model, the quantity of described oil hole is 4.
In preferred embodiment of the utility model, also be provided with mounting hole on the described inner ring.
The beneficial effects of the utility model are: the utility model has disclosed a kind of flanged (FLGD) biserial angular contact bearing, the bearing enclose that adopts integrated, and adopt spacer ring to eliminate the axial internal clearance of bearing in the middle of two outer rings, can improve the installation precision of bearing, make bearing have good rigidity and stable service behaviour, thereby prolong the working life of bearing; In addition, adopt overall construction design, can strengthen seal space, make sealing configuration more reliable.
