Abstract

The utility model relates to a bearing with a support, which comprises a self-aligning roller bearing with an extended inner ring comprising an inner ring, an outer, a retainer and a plurality of rollers, wherein, the retainer consists of two punched iron retainers, and a movable septal ring is arranged between the two retainers. The two retainers are evenly distributed with pockets which are in cross-shaped arrangement. The rollers are symmetric spherical rollers, and sliding fit is adopted for between spherical surfaces of the rollers and the pockets of the retainers, between the spherical surfaces of the rollers and a rollaway nest on the outer circle of the inner ring, and between the spherical surfaces of the rollers and a rollaway nest on the inner circle of the outer ring. The utility model is characterized in that a bearing support is arranged outside the outer ring and the width of the bearing support is larger than that of the outer ring; and two circumferential grooves are arranged on the inner circle of the bearing support. The two circumferential grooves are positioned on two ends of the outer ring, and a limit ring is arranged inside each circumferential groove. The limit rings are raised outside the circumferential grooves and are blocked on two head faces of the outer ring. A bearing seat is not required during installing, so the bearing with the support can be used and installed conveniently, and is applicable to the self-aligning roller bearing with the extended inner ring.

Description

Rolling bearing units

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 rolling bearing units.This rolling bearing units do not need bearing support during installation, use and install more convenient.

For addressing the above problem, take following technological scheme:

Rolling bearing units of the present utility model comprise 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 outside, its outer ring of rolling bearing units of the present utility model, when on the main equipment that rolling bearing units 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

Accompanying drawing is a rolling bearing units structural representation of the present utility model.

Embodiment

As shown in drawings, rolling bearing units of the present utility model contain 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.
