Abstract
The utility model relates to a bearing, in particular to an extended-inner ring self-aligning roller bearing with a bearing block. The roller bearing comprises an extended-inner ring self-aligning roller bearing comprising an inner ring, an outer ring, a retainer and a plurality of rollers. As the bearing block is arranged outside the outer ring of the roller bearing, when applied to large-scale equipment comprising mine conveyors and the like, the roller bearing needs not to be additionally assembled with a bearing block so as to be convenient for large-scale equipment users to use and install.
Description
Technical field
The utility model relates to a kind of bearing.Particularly, be the wide inner ring selfaligning roller bearing that has bearing support.
Background technique
At present, the various selfaligning roller bearings that mechanically use all do not have bearing support.When this bearing is installed, need processing mounting holes on equipment.For compact structure, volume small device, by all being provided with shell thereon, need only machining bearing mounting hole on its shell, and Bearing Installation is got final product in mounting hole.And,, generally all do not have shell because equipment is bigger for the main equipment that resembles mine conveyor and so on, need bearing support to be set bearing is installed by support and on support.Owing to need join bearing support in addition when installing, give the main equipment user use and installation has brought trouble.
The model utility content
Problem to be solved in the utility model provides a kind of roller bearing.This roller bearing does not need bearing support during installation, use and install more convenient.
For addressing the above problem, take following technological scheme: roller bearing of the present utility model comprises wide inner ring selfaligning roller bearing, and this wide inner ring selfaligning roller bearing is made of inner ring, outer ring, retainer and some rollers.Retainer wherein is made up of two punching press iron retainers, and spacer ring in the activity is installed between two retainers.Be evenly equipped with the pocket hole on two retainers, and cross-shaped layout between the pocket hole on two pressing cages.Roller is the symmetry properties spherical roller, all is between the raceway on the circle between the raceway between the pocket hole of their sphere and retainer, on the inner ring cylindrical and in the outer ring to be slidingly matched.Be characterized in that there is bearing support the outside, outer ring, the width of bearing support has two circumferential recess on the circle greater than the outer ring in the bearing support.Described two circumferential recess are in the two ends, outer ring, and stop ring is all arranged in each circumferential recess.Described stop ring protrudes outside the circumferential recess and on the both ends of the surface of retaining in the outer ring.The width of two circumferential recess is all greater than the width of stop ring, and that cell wall of their inboards is mutually concordant with the outer ring.All there is seal ring in the two stop rings outside, this two seal ring all contains ring skeleton, the inboard of ring skeleton is fixed with flexible rings, the interior circular diameter of flexible rings closely cooperates so that justify respectively and be between the interior circle of the cylindrical of inner ring and bearing support in ring skeleton cylindrical and the flexible rings less than the interior circular diameter of ring skeleton.
Take such scheme, have the following advantages: because there is bearing support its outside, outer ring of roller bearing of the present utility model, when on the main equipment that roller bearing of the present utility model is applied to resemble mine conveyor and so on, do not need to join in addition bearing support, give the main equipment user use and installation has brought convenience.
Description of drawings
Fig. 1 is a roller bearing structural representation of the present utility model.
Embodiment
As shown in drawings, roller bearing of the present utility model contains wide inner ring selfaligning roller bearing, and this wide inner ring selfaligning roller bearing is made of inner ring 1, outer ring 6, retainer and some rollers 10.Retainer wherein is made up of two punching press iron retainers 9, and two 9 of punching press iron retainers are equipped with middle spacer ring 4.Be evenly equipped with the pocket hole on the two punching press iron retainers 9, and cross-shaped layout between the pocket hole on two pressing cages 9.Described roller 10 is the symmetry properties spherical roller, all is between the raceway between the raceway between their sphere and pocket hole, on inner ring 1 cylindrical and the outer ring 6 on the circle to be slidingly matched.6 outsides are provided with bearing support 5 in the outer ring, and the width of this bearing support is processed with two circumferential recess on the circle greater than the width of outer ring 6 in the bearing support 5.Described two circumferential recess are in the two ends of outer ring 6 respectively, all be equipped with in each circumferential recess stop ring 7, two stop rings 7 all protrude outside the circumferential recess and retaining on the both ends of the surface of outer ring 6, make between outer ring 6 and bearing support 5 axial to be secure fit.
For adapting to the use needs of rugged environment, avoid dust to enter between the inner ring 1 and outer ring 6 of bearing, be provided with seal ring in two stop rings, 7 outsides.This two seal ring all contains ring skeleton 3, and the outer edge of this two ring skeleton all is processed with inside flanging 8, and their place, inboard inside edge is fixed with flexible rings 2.This flexible rings is a rubber ring, and circular diameter closely cooperates so that justify respectively and be between the interior circle of the cylindrical of inner ring 1 and bearing support 5 in ring skeleton 3 cylindricals and the flexible rings 2 less than the interior circular diameter of ring skeleton 3 in it.
The needs that be to adapt to distinct device, the width of two circumferential recess can be greater than the width of stop ring 7, and make that cell wall of their inboards mutually concordant with outer ring 6, are activity between outer ring 6 and bearing support 5 axial on limited distance and cooperate thereby can make.
