Abstract
The utility model relates to a four-row cylinder roller bearing for strengthened rolling mills, which is composed of an outer ferrule, an outer retaining ring, an outer sleeve ring, rollers, a retainer and an inner shaft sleeve. The utility model is characterized in that a cylinder side of the retainer forms an outer rolling edge shape, and has the advantages of reasonable structure, low cost, and easy installation and repair. The utility model can increases the number of rollers at maximum, can bear heavier radial load, can avoid the assembly method of traditional bearing from a notch of an outer ring to beat rollers, and can fundamentally eliminate the phenomenon of rolling tracks scratching, which is an ideal four-row cylinder roller bearing for strengthened rolling mills.
Description
The utility model relates to a kind of bearing, and particularly a kind of reinforced rolling mill is with four routine cylinder roller bearings.
Present rolling mill bearing because retainer will occupy a large amount of spaces, has brought difficulty for the quantity that increases roller.
The purpose of this utility model is that a kind of reinforced rolling mill of design is with four routine cylinder roller bearings, overarm retainer structure in this bearing adopts, can increase the quantity of roller to greatest extent, even can fill roller, directly roller is packed in the retainer pocket hole, in order to overcome existing deficiency with rolling mill bearing.
The purpose of this utility model can reach by following embodiment: this bearing is made up of outer collar, outer back-up ring, outer sleeve, roller, retainer and internal axle sleeve, outer collar is a cylindrical shape, bulge loop is arranged in the middle of its inwall, outer collar has two, two outer collar shapes are identical, and the outer collar inwall contacts with roller, and outer back-up ring is a ring shape, outer back-up ring has two, and it is located at the outside of two outer collar respectively.Outer sleeve is an annular, and it is located at the centre of two outer collar inboards, and roller rolls shape for circle, and retainer is the outer crimping shape of cylinder one side, and roller is contained in the retainer pocket hole, and roller, retainer are contained between outer collar and the internal axle sleeve, and internal axle sleeve is a cylindrical shape.
Advantage of the present utility model is rational in infrastructure, cheap, maintenance, easy for installation, can increase roller quantity to greatest extent, can bear heavier radial load, can avoid traditional bearing to squeeze into the assembly method of roller from the outer shroud breach, fundamentally eliminate the phenomenon that raceway scratches, be a kind of desirable reinforced rolling mill four-line column roller bearing.
Below in conjunction with accompanying drawing the utility model is done and to be described in detail
Fig. 1 is a part overall structure cross-sectional schematic of the present utility model;
Fig. 2 looks overall diagram for a left side.
As shown in Figure 1, 2, this bearing is made up of outer collar 1, outer back-up ring 2, outer sleeve 3, roller 4, retainer 5 and internal bearing sleeve 6, and outer collar 1 is a cylindrical shape, bulge loop 7 is arranged in the middle of its inwall, outer collar 1 has two, and outer collar 1 shape is identical, and outer collar 1 inwall contacts with roller 4.Outer back-up ring 2 is a ring shape, and outer back-up ring 2 has two, and it is located at the outside of two outer collar respectively.Outer sleeve 3 is an annular, and it is located at the centre of two outer collar inboards.Roller 4 rolls shape for circle, and retainer is the outer crimping shape of cylinder one side, and roller 4 is contained in the retainer 5 pocket holes, and roller 4, retainer 5 are contained between outer collar 1 and the internal axle sleeve 6, and internal axle sleeve 6 is a cylindrical shape.All parts of the utility model are steelwork, special suggestion, and its retainer 5 also is a steelwork, so just can save copper material, reduces cost.
The utility model can be made multi-form biserial bearing, but corresponding part will suitably increase.
