Abstract
The invention discloses a single row cylindrical roller bearings for rolling mills with side ribs, including a outer ring, a inner ring, and a row of Cylindrical Rollers between the two rings. One end of the inner ring is provided with a platform bulging along the radial direction to function as a rib of the cylindrical roller, the other end of the inner ring avails a conical external surface which narrows down at the bearing end and transit into the external cylindrical surface of the inner ring in the middle part. On either end of the external surface of the outer ring (1) are provided at axis direction with a bulged part that function as the rib of the cylindrical rollers. By adopting the single side setting of the ribs of the inner ring, the invention not only facilitates the assembling of the bearing but also ensures the restriction of the bearing rollers at the axis direction. The bearing of the invention are mainly applied to industries like milling, machinery, and metallurgy. The maintenance support component features an improved lubrication and therefore a more flexible turning as well as great improvement in the use life of the bearing.
Description
Technical field
The present invention relates to a kind of rolling mill single-row cylinder roller bearing, more particularly relate to the roller bearing technical field of bearings.
Background technique
Milling train roller bearing structure is made up of outer ring, inner ring, roller and retainer, and single-row roller bearing uses on the milling train of each steel rolling mill, bearing working in impact, high temperature, at a high speed, heavy duty, insufficient lubrication, high pressure water wash away etc. under the bad working environments condition.
Retainer plays guiding and isolates the effect of roller, bearing roller in the running rolls on the raceway of Internal and external cycle, the running of roller driving bearing retainer is again rotated, thereby cause roller and retainer to produce friction, when the bearing rotating speed is higher, can produce bigger friction owing to action of centrifugal force, thereby reduce the transmission efficiency and the life-span of bearing, the bearing capacity difference of ball bearing is its outstanding shortcoming.
Summary of the invention
The present invention provides a kind of band side rib rolling mill single-row cylinder roller bearing for solving on the above technical problem, has solved problems such as bearing capacity difference.
A kind of band side rib rolling mill single-row cylinder roller bearing comprises outer ring, inner ring, and the columna roller between inner ring and outer ring.Wherein, a side end of inner ring is radially to being outside equipped with boss, as the rib of cylindrical roller; The outer wall of the end side of inner ring becomes conical surface, and conical surface is narrow at the position of bearing face, transits to the external cylindrical surface of described inner ring in the intermediate portion.Outer ring outer wall both side ends is respectively arranged with flange as the cylindrical roller rib to axis direction.
In addition, band side rib rolling mill single-row cylinder roller bearing of the present invention, its cylindrical roller is fixed on the retainer by riveting pin and retainer cover.The inner ring external diameter is the ladder annular, a roller raceway that a side rib is set, the inner ring external diameter fillet of leaning now to one side, then to the other is arranged, the equal rounding in inner ring endoporus both sides in the middle of the inner ring external diameter; The outer ring external diameter fillet of leaning now to one side, then to the other; The equal rounding in endoporus both sides, outer ring; In the middle of the endoporus of outer ring a rectangle roller raceway is arranged, two arc grooves are arranged in the roller raceway.Its retainer one side is equally distributed teeth, and roller is evenly distributed between the teeth, and the hierarchic structure of placing the retainer cover is arranged on the teeth, and through hole is arranged on the hierarchic structure.
The present invention is provided with the assembling that rib had both made things convenient for bearing by its inner ring is one-sided, can guarantee bearing roller qualification in the axial direction again.The present invention compared with prior art has the following advantages: significantly reduced friction, thereby improved bearing life greatly.

Embodiment
Shown in Fig. 1-5, a kind of band side rib rolling mill single-row cylinder roller bearing comprises outer ring 1, inner ring 2, and the columna roller 3 between inner ring and outer ring.Wherein, a side end of inner ring 2 is radially to being outside equipped with boss, as the rib of cylindrical roller; The outer wall of the end side of inner ring 2 becomes conical surface, and conical surface is narrow at the position of bearing face, transits to the external cylindrical surface of inner ring 2 in the intermediate portion.Outer ring 1 outer wall both side ends is respectively arranged with flange as the cylindrical roller rib to axis direction.
In addition, band side rib rolling mill single-row cylinder roller bearing of the present invention, its cylindrical roller 3 is fixed on the retainer 4 by riveting pin 5 and retainer cover 6.Inner ring 2 external diameters are the ladder annular, a roller raceway that a side rib is set, the inner ring 2 external diameters fillet of leaning now to one side, then to the other are arranged, the equal rounding in inner ring 2 endoporus both sides in the middle of inner ring 2 external diameters.The outer ring 1 external diameter fillet of leaning now to one side, then to the other; The equal rounding in 1 endoporus both sides, outer ring; In the middle of 1 endoporus of outer ring a rectangle roller raceway is arranged, two arc grooves are arranged in the roller raceway.And retainer 4 one sides are equally distributed teeth, and roller 3 is evenly distributed between the teeth, and the hierarchic structure of placing retainer cover 6 is arranged on the teeth, and through hole is arranged on the hierarchic structure.
A kind of preferred embodiment: with the nominal outside diameter is the rolling mill four-point contact ball bearing of 520mm, and the width of outer ring is 80mm; The number of ball roller holes is 12, and the diameter of ball roller holes is 27.2mm.
