Abstract
The utility model relates to a kind of single-row spherical-roller bearing with seal ring.It comprises outer ring and inner ring, and outer ring sleeve is in the outside of inner ring, and have the retainer of annular between outer ring and inner ring, the middle part of retainer is evenly equipped with pocket hole along its circumference, all has the roller in waist drum shape in pocket hole, coordinates between roller with pocket hole in rolling.The position of the corresponding roller of the internal surface of described outer ring, the outer surface of inner ring is all in inner ball surface shape.Described outer ring there is oilhole.Be characterized in the seal ring all having annular between the inner ring of described retainer both sides and outer ring.The working life of this bearing is longer.
Description
Technical field
The utility model relates to a kind of single-row spherical-roller bearing, is the single-row spherical-roller bearing of band seal ring specifically.
Background technique
All know in machinery is capable, large and need to compensate in the occasion of error of centralization at radial load, carry out supported mechanical solid of rotation by using single-row spherical-roller bearing.
At present, the single-row spherical-roller bearing used in industry comprises outer ring and inner ring, and outer ring sleeve is in the outside of inner ring, the retainer of annular is had between outer ring and inner ring, the middle part of retainer is evenly equipped with pocket hole along its circumference, all has the roller in waist drum shape in pocket hole, coordinates between roller with pocket hole in rolling.The position of the corresponding roller of the internal surface of described outer ring, the outer surface of inner ring is all in inner ball surface shape.Described outer ring there is oilhole.In use, the dust in environment, foreign material etc. are easy to enter into Bearing inner to this single-row spherical-roller bearing, thus accelerate the wearing and tearing of bearing, make working life lower.
Model utility content
The technical problems to be solved in the utility model is to provide a kind of single-row spherical-roller bearing with seal ring, and the working life of this bearing is longer.
For solving the problem, provide following technological scheme:
The single-row spherical-roller bearing of band seal ring of the present utility model comprises outer ring and inner ring, outer ring sleeve is in the outside of inner ring, and have the retainer of annular between outer ring and inner ring, the middle part of retainer is evenly equipped with pocket hole along its circumference, all there is the roller in waist drum shape in pocket hole, coordinating in rolling between roller with pocket hole.The position of the corresponding roller of the internal surface of described outer ring, the outer surface of inner ring is all in inner ball surface shape.Described outer ring there is oilhole.Be characterized in the seal ring all having annular between the inner ring of described retainer both sides and outer ring.
The angle being described oilhole center line and outer ring radial line to further improvement of the utility model scheme is 45 °.The advantage of such improvement is because the inner surface that roller centre is relative is maximum stress place, so make oilhole avoid maximum stress place, decreases the wearing and tearing that oilhole causes roller simultaneously, extends the working life of bearing.
Take above scheme, have the following advantages:
Due to the single-row spherical-roller bearing of band seal ring of the present utility model, comprise outer ring, outer ring, retainer and roller, between the inner ring of retainer both sides and outer ring, all have the seal ring of annular.So in use, the dust in environment, foreign material stop by seal ring, not easily enter into Bearing inner, thus avoid, because dust, foreign material etc. enter the problem that Bearing inner causes bearing wear to be accelerated, extending the working life of bearing.
Accompanying drawing explanation
Fig. 1 is the structural representation of the single-row spherical-roller bearing of band seal ring of the present utility model.
Embodiment
Below in conjunction with accompanying drawing, the utility model is described in further detail.
As shown in Figure 1, the single-row spherical-roller bearing of band seal ring of the present utility model comprises outer ring 1 and inner ring 3, outer ring 1 is enclosed within the outside of inner ring 3, the retainer 2 of annular is had between outer ring 1 and inner ring 3, retainer 2 is punching press iron retainer 2, the middle part of retainer 2 is evenly equipped with pocket hole 6 along its circumference, all has the roller 4 in waist drum shape in pocket hole 6, coordinates between roller 4 with pocket hole 6 in rolling.The position of the corresponding roller 4 of the internal surface of described outer ring 1, the outer surface of inner ring 3 is all in inner ball surface shape.There is oilhole 5 described outer ring 1, and the angle of oilhole 5 center line and outer ring 1 radial line is 45 °.The seal ring 7 of annular is all had between the inner ring 3 of described retainer 2 both sides and outer ring 1.
In use, the seal ring 7 of retainer 2 both sides can by dust gear in the outside of bearing for this single-row spherical-roller bearing, thus avoids, because dust, foreign material etc. enter the problem that Bearing inner causes bearing wear to be accelerated, extending the working life of bearing.And the oilhole 5 of this single-row spherical-roller bearing avoids maximum stress place, decrease the wearing and tearing that oilhole 5 pairs of rollers 4 cause, extend the working life of bearing further.
