Abstract
The invention belongs to the technical field of steel industry, and relates to a four-row tapered roller bearing used in a brand new hot milling roll. The bearing mainly consists of a wide-angle outer ring (1), a roller (2), an outer ring spacer (3), a retainer (4), an inner ring spacer (5), a wide-angle double-race outer ring (6) and an inner ring (7); the roller (2), the retainer (4) and the inner ring (7) form an inner assembly which is assembled on the wide-angle outer ring (1), the outer ring spacer (3) is assembled on the inner assembly, the wide-angle double-race outer ring (6) is assembled on the outer ring spacer (3), the inner ring spacer (5) is assembled on the wide-angle double-race outer ring(6), and the wide-angle outer ring (1) is assembled on the outer ring spacer (3). The four-row tapered roller bearing has the beneficial effects of meeting the radial and axial load requirements of the bearing, and solving the problems of end face wear of the bearing, retainer melt, bearing burning loss, short service life and the like.
Description
Technical field
The present invention relates to four-row tapered roller bearing, be mainly used in steel industry, be used on the hot rolled plate milling train precision rolling working roll.
Background technique
Existing milling train precision rolling working roll bearing mainly adopts cylinder/circular cone combination bearing, bears radial and axial load respectively.Because so this bearing is the structural imperfection that has, the inner ring of cone and cylinder often produces relative rotation, end wear with the cylindrical roller inner ring, cause the copper holder grazing of the steel retainer and the cylindrical roller of tapered roller, the overheated copper cage of cylindrical roller that makes of local appearance is melted, and then the rolling element rotation is obstructed, cause bearing burnt.No matter the product or the working life of state's inner bearing that are Aktiebolaget SKF at most all can only reach 3000 hours, do not reach usage requirement.
Summary of the invention
The purpose of this invention is to provide a kind of four-row tapered roller bearing for full new hot-rolling mill, can satisfy the radial and axial load requirement of bearing, can also prevent the generation of phenomenons such as bearing face wearing and tearing, retainer thawing, bearing burnt effectively, prolong the working life of bearing.
In order to achieve the above object, technological scheme of the present invention is as follows:
Four-row tapered roller bearing for full new hot-rolling mill, mainly form by wide-angle outer ring, roller, outer ring spacer, retainer, cone spacer, wide-angle outer ring with double raceway and inner ring, roller, retainer and inner ring are formed inner assembly, this inner assembly is assembled on the wide-angle outer ring, outer ring spacer is assembled on the described inner assembly, the wide-angle outer ring with double raceway is assembled on the outer ring spacer, and cone spacer is assembled on the wide-angle outer ring with double raceway, and the wide-angle outer ring is assembled on the outer ring spacer.
The invention has the beneficial effects as follows: this four-row tapered roller bearing has not only satisfied the radial and axial load requirement of bearing, can also prevent the generation of phenomenons such as bearing face wearing and tearing, retainer thawing, bearing burnt effectively, prolongs the working life of bearing.
Description of drawings
Fig. 1 is the structural representation of four-row tapered roller bearing for full new hot-rolling mill of the present invention.
Among the figure: 1, wide-angle outer ring, 2, roller, 3, outer ring spacer, 4, retainer, 5, cone spacer, 6, the wide-angle outer ring with double raceway, 7, inner ring.
Embodiment
Below in conjunction with accompanying drawing the present invention is done description in further detail:
As shown in Figure 1, the present invention mainly is made up of wide-angle outer ring 1, roller 2, outer ring spacer 3, retainer 4, cone spacer 5, wide-angle outer ring with double raceway 6 and inner ring 7, roller 2, retainer 4 and inner ring 7 are formed inner assembly, its assembly process is: the wide-angle of packing into earlier outer ring 1, reinstall the inner assembly that roller 2, retainer 4 and inner ring 7 are formed, reinstall outer ring spacer 3, reinstall wide-angle outer ring with double raceway 6, reinstall cone spacer 5, reinstall the inner assembly that roller 2, retainer 4 and inner ring 7 are formed, reinstall outer ring spacer 3, reinstall wide-angle outer ring 1 at last.
The radial load that bears according to bearing and the concrete numerical value of thrust load, through calculating and finite element analysis, choose only main parameter, comprise parameters such as bigger contact angle, rolling element diameter, length, quantity, produce four-row tapered roller bearing for full new hot-rolling mill of the present utility model.
The present invention is through the inner proof of using, not only well satisfied the radial and axial load requirement of bearing, but also solved problems such as bearing face wearing and tearing, retainer thawing, bearing burnt, life-span weak point well, make reach more than 8000 hours the working life of bearing.
