Abstract
The invention discloses a cylindrical roller bearing without an inner ring for a rolling mill, which has a four-row structure and comprises a pair of outer rings (01) which is juxtaposed. Two ends of each outer ring (01) are provided with a flange respectively. Two rows of cylindrical rollers (04, 24) prop side by side and are limited in a retainer, and the axial positions of the cylindrical rollers are limited by the flanges. Each retainer comprises an annular retainer seat (06) and a retainer cover (16); the circumference of the retainer seat (06) is evenly distributed with pocket holes; and after the cylindrical rollers are loaded in the pocket holes, the retainer cover (16) is buckled on the retainer seat (06), and the retainer cover (16) and the retainer seat (06) are connected by a rivet, so that the cylindrical rollers are accommodated in the pocket holes. The bearing of the invention is mainly used on a rolling bearing mill, the cylindrical rollers of the mill are directly contacted with a roll neck of a roller, and the surface of the roll neck is used as a rolling surface. Because the bearing is not provided with the bearing inner ring, the size of the roll neck of the roller can be increased, and the aim of increasing the intensity of the roller can be achieved.
Description
Technical field
The present invention relates to a kind of bearing, more particularly, relate to a kind of four-line column roller bearing.
Background technique
The roller-mill bearing of prior art is made of two outer rings, inner ring, two retainers and four-row cylindrical roller.Because this bearing structure restriction, milling train can not use thicker roller neck, causes some rolls to rupture at the roll neck place.
Summary of the invention
At the problems referred to above, the invention provides a kind of milling train cylindrical roller bearing without inner ring, on the basis of simplifying bearing structure, lay the first stone for increasing the roller neck diameter of axle, thereby can improve roll strength.
In order to achieve the above object, the present invention has constructed a kind of cylindrical roller bearing without inner ring for rolling mill, is four array structures, comprises a pair of juxtaposed outer ring.The two ends of each outer ring are respectively arranged with the flange that protrudes to the axle center; Per two line column rollers are defined in the retainer side by side by putting, and by the flange limit axial position of outer ring.Each retainer comprises the maintenance stand and the retainer lid of ring-type.Be evenly equipped with the pocket hole on the circumference of maintenance stand, be used to load and unload cylindrical roller; Pack into behind the cylindrical roller, the retainer lid is buckled in and keeps on the stand, and connects maintenance stand and retainer lid by rivet, thereby cylindrical roller is housed inside in the pocket hole.
Under the optimal way, it is short than the opposite side roller length that one of per two row rollers sidewinder sub-length.
By technique scheme, cylindrical roller bearing without inner ring of the present invention is mainly used on the rolling bearing mill, is made up of outer ring, retainer and along the circumferential direction uniform cylindrical roller.Be characterized in not having bearing inner race, cylindrical roller directly contacts with roller neck, neck surface is as rolling surface.The present invention is under the situation identical with roller-mill bearing outer ring, roller and the retainer of prior art, and existing roller-mill bearing has more following advantage:
1, because bearing inner race is not set, thereby can increase roller neck, roller neck can increase by 10% one 15% usually.
2, reduced the manufacture cost of bearing.
3, save the operation and the equipment of running in bearings inner ring, reduced the frock cost.
4, overcome the prior art inner rings of rolling-mill bearings big shortcoming that takes up room.
5, increase the intensity of roll, can enlarge the kind and the rolling specs of rolled products.
Description of drawings
Fig. 1 be cylindrical roller bearing without inner ring for rolling mill of the present invention partly cut open structural representation, omit lower half portion of symmetry among the figure.
Embodiment
As shown in Figure 1, cylindrical roller bearing without inner ring for rolling mill of the present invention is four array structures, comprises a pair of juxtaposed outer ring 01.The two ends of each outer ring 01 are respectively arranged with the flange that protrudes to the axle center.Per two line column rollers 04,24 are defined in the retainer side by side by putting, and by the flange limit axial position of outer ring.Each retainer comprises the maintenance stand 06 and the retainer lid 16 of ring-type.Be evenly equipped with the pocket hole on the circumference of maintenance stand 06, be used to load and unload cylindrical roller.Pack into behind the cylindrical roller, retainer lid 16 is buckled in and keeps on the stand 06, be connected and fixed above-mentioned maintenance stand 06 and retainer lid 16 by rivet 09, thereby cylindrical roller is housed inside in the pocket hole.
Among the figure, the length of left side rollers 24 is short than the length of right side roller 04.Also can isometricly be provided with as required.
Claims (2)
1. a cylindrical roller bearing without inner ring for rolling mill is characterized in that, is four array structures, comprises a pair of juxtaposed outer ring (01), and the two ends of each described outer ring (01) are respectively arranged with the flange that protrudes to the axle center;
Per two line column rollers (04,24) are defined in the retainer side by side by putting, and by the flange limit axial position of described outer ring;
Each described retainer comprises the maintenance stand (06) and the retainer lid (16) of ring-type; Be evenly equipped with the pocket hole on the circumference of described maintenance stand (06), be used to load and unload cylindrical roller; Pack into behind the cylindrical roller, described retainer lid (16) is buckled in and keeps on the stand (06), and connects described maintenance stand (06) and retainer lid (16) by rivet, thereby described cylindrical roller (04,24) is contained in the described pocket hole.
2. cylindrical roller bearing without inner ring for rolling mill according to claim 1 is characterized in that, it is short than opposite side roller (04) length that one of per two row rollers sidewinder son (24) length.
