Abstract
The invention relates to a bidirectional thrust tapered roller bearing for a novel overall holding frame, which is mainly applied to a finishing working roll of a hot rolling sheet material rolling mill in steel industry. In the bidirectional thrust tapered roller bearing, the combination of a conventional holding frame seat and a cover is improved for an overall holding frame structure, and brass is adopted as a material, so that the overall strength of the holding frame is improved; and when the bidirectional thrust tapered roller bearing is assembled, because of the design of a special tool for pivoting the holding frame, a roller can flexibly rotate in a pocket of the holding frame, so that interference phenomenon of the holding frame and the roller in a bearing state is avoided, the problem of the early damage of the holding frame is solved very well, and the service life of the bearing is obviously prolonged.
Description
Technical field
The present invention relates to a kind of bidirectional thrust tapered roller bearing that is mainly used in the novel overall holding frame on the steel industry hot rolled plate milling train precision rolling working roll.
Background technique
Be applied to the serial bidirectional thrust tapered roller bearing on the steel industry hot rolled plate milling train precision rolling working roll, adopt a fabricated structure that keeps a stand and a retainer lid traditionally, because the operating mode very severe in rolling process, bearing is bearing bigger impulsive load, retainer also often is subjected to irregular axial force and breakage problem occurs, cause bearing fragile, therefore, improving retainer structural type is the effective ways that address this problem.
Summary of the invention
In order to solve the breakage problem of retainer, improve the working life of bearing, the invention provides a kind of bidirectional thrust tapered roller bearing of novel overall holding frame.
Technological scheme of the present invention is: the bidirectional thrust tapered roller bearing of novel overall holding frame comprises seat ring 1, retainer 2, blowout patche 3, middle spacer ring 4 and roller 5.Roller 5 installs in the retainer 2, cutter seal and pinning roller 5 on the beam of the pocket hole of retainer 2, and retainer 2 is formed roller assemblies with roller 5, and roller assembly and seat ring 1, blowout patche 3 and middle spacer ring 4 are formed a whole set of bearing.Wherein retainer 2 is an integral type instrument riveted retainer, and material is a brass.
The invention has the beneficial effects as follows: the retainer structure that is improved to integral type by traditional maintenance stand and lid two body combined types, select brass on the material for use, improved the bulk strength of retainer, the instrument riveted retainer of design specialized during assembling, roller can be rotated in retainer pocket hole neatly, avoided retainer and the roller interference phenomenon under loaded state, solved the early stage damage problem of retainer well, and bearing has obviously improved working life.
Description of drawings
Fig. 1 is a structural representation of the present invention.
