Description

The assembled connecting device of cover or split bearing in the backing roll split

Technical field

The present invention relates to a kind of assembled connecting device, relate in particular to the assembled connecting device of straightener with cover or split bearing in the backing roll split.

Background technology

The characteristics that the steel rolling production-line of iron and steel enterprise all has high-speed production, works continuously, control accuracy is high, especially the finishing production line of hot rolling, last procedure as hot rolling technology control end product quality, finishing leveller equipment performance, particularly the performance of straightener backing roll directly influences finished product output and quality.But, the greasy dirt coiled sheet that present finishing leveller equipment is caused is day by day obviously with outstanding, for solving the greasy dirt problem, existing slab straightener backing roll adopts the backing roll of anti-greasy dirt, referring to Fig. 1, Fig. 2, inner room is equipped with skeleton sealing ring in backing roll overcoat outside rolling element and the backing roll, and cover is fixed by end cap in the backing roll.But the maintenance of this backing roll dismounting is because the restriction of supported roller installing space position, very inconvenience is repaired in dismounting, and in actual production, the greasy dirt coiled sheet that is caused except the finishing leveller equipment influences the product quality, brown iron oxide also enters in the backing roll rolling element easily, thereby has influence on end product quality.

Development along with Baosteel straightener backing roll technology, Baosteel has been developed a kind of dustproof backing roll technology (ZL 200420082414.5) of slab straightener of fast changeable, overcome difficult, the relatively poor defective of anti-dust performance of existing backing roll dismounting, can realize the fast assembling-disassembling and the maintenance of backing roll, dustproof and good seal performance.Its adopted split type in nested structure, realized the Fast Installation of backing roll on wallboard at the scene, be convenient to fast assembling-disassembling and maintenance, and can reduce the backing roll wallboard the spare part amount.The sealing of basin shape clamping ring is adopted in the sealing of cover interblock in the split; The sealed at both ends double-layer sealing structure that adopted of backing roll, ground floor is a dust ring, enters backing roll inside in order to stop brown iron oxide; The second layer is a skeleton contact seal circle, avoids from backing roll overcoat and inner ring oil impregnate.This patent of invention technology is compared with existing backing roll, has the advantages that to change quick, dustproof effect and good seal performance.

There is convex shoulder cover piece outer end in the slab straightener of the fast changeable of this patent of invention technology backing roll that prevents dust, its described split, and skeleton sealing ring is housed on the convex shoulder outer ring, and dust ring is equipped with outer inner room in the convex shoulder outside.Therefore, nested structure is when the backing roll general assembly in this invention split type, and the device that also needs to be correlated with cooperates could implement assembling quickly and accurately.

Summary of the invention

The object of the invention is to provide the coupling arrangement of interior cover of a kind of backing roll split or split bearing, to realize the Fast Installation of backing roll or split bearing.

The object of the present invention is achieved like this:

The assembled connecting device of cover or split bearing is characterized in that in a kind of backing roll split, comprising: a moulding bulge loop, be arranged on one, and also fix an eccentric clamping lever on this axle; The a pair of end cap that clamps for the treatment of the connector two ends that is pressed in; Cover in one location is set in and treats in the connector; The auxiliary scale of the one location moulding bulge loop degree of depth.

Wherein, the end shape of described moulding bulge loop matches with the end shape that is connected of interior cover of the split of the backing roll that will assemble or split bearing, and also is provided with a bearing between described moulding bulge loop and the axle.Described backing roll clamps end cap and is the discoid of band endoporus, is evenly equipped with bolt hole on it and is used for bolt fastening and clamping with the split type inner ring of backing roll.Cover can overlap in radially to split and effectively locate in the described location, guarantees stablizing when cover connects in the split.On handle, can also be provided with the auxiliary scale of a location moulding bulge loop degree of depth, be used to realize that the moulding bulge loop on the coupling arrangement enters the connection position quickly and accurately.

The present invention is owing to adopted above-mentioned technical scheme, make it compared with prior art, have following advantage and good effect: the assembling that the present invention can finish backing roll or other split bearing fast connects, applied range, connecting stability, assembling intensity and assembling speed improves a lot, more large batch of production can be adapted to, assembly precision can be significantly improved.
