The vertical mill roll and the vertical roller shell are fixedly connected through a special nut, the vertical mill roll, the vertical roller bearing and the lining sleeve are connected through the mill roll shaft penetrating through the center of the vertical roller bearing, a positioning plate positions the nut and locks the lining sleeve, and the outer end face of the vertical roller shell and the outside diameters of the nut and the lining sleeve reliably seal the vertical roller shell and the bearing respectively through heterotypic sealing rings and another group of sealing ring components.

Description

A kind of novel edger roll bearing arrangement assembly

Technical field

The utility model relates to steel rolling finishing equipment field in a kind of iron and steel metallurgical industry, relates to a kind of novel edger roll bearing arrangement assembly concretely.

Background technology

In recent years, along with the fast development of China's industry, very big variation has taken place in the steel products market of China, to the also raising accordingly of requirement of rolling mill.Thirty years of age roller bearing is the important component part of rolling mill, and the quality of its performance is to weigh the important indicator of rolling mill performance quality.The general taper roll bearing of the general employing of edger roll bearing in the market is a matched in clearance between cover and the axle in the double-row conical bearing, and not shock-resistant, interior cover destructiveness takes place easily bursts.Secondly, because its version, and it is insufficient to cause bearing oil to add, the accident that bearing burns out easily takes place, and be matched in clearance between cover and the axle in the double-row conical bearing, cooling fluid, oxide skin and other field trashes enter in the bearing easily, destroy the bearing lubrication function, are interrupted the service life of bearing.

Summary of the invention

In view of the defective that existing procucts exist, the utility model is that a kind of novel edger roll bearing arrangement assembly will be provided.

For achieving the above object, a kind of novel edger roll bearing arrangement assembly of the utility model is characterized in that: be made up of edger roll bearing, edging roll, roll mandrel, edger roll housing and lining.Edging roll and edger roll housing are fixed together by special nut, edging roll, edger roll bearing and lining link together by the roll mandrel that passes the edger roll bearing centre, location-plate is with nut positioning and locking lining, and edger roll housing outer face and nut, lining external diameter are organized seal ring assembly with edger roll housing and bearing positiver sealing with fixing ring and another respectively.

Be provided with locking nut between described edger roll housing and the edger roll bearing, be connected to sunk screw on the locking nut, be provided with in the periphery of sunk screw and loosen brill, and be provided with " O " RunddichtringO between edger roll housing and the edger roll bearing.

Described special nut is made up of soket head cap screw, spring washer and seal washer, is provided with " V " RunddichtringO in the junction of special nut and edger roll housing.

The utility model is compared with existing product, has following outstanding advantage and good effect:

1, the utility model is to utilize end cap, lining and special nut that overall package is in the same place, and edger roll and bearing couple together by roll mandrel.Utilize location-plate with nut positioning and locking lining, end cap outer face and nut, lining external diameter are organized seal ring assembly with edger roll housing and bearing positiver sealing with fixing ring and another respectively.The sealing of the edger roll bearing of Zeng Jiaing like this, can effectively stop cooling fluid, oxide skin and other field trashes to enter in housing and the bearing, avoid cooling fluid to mix with lubricating grease, prevented the lubricating function of cooling fluid destruction lubricating grease, stop the excessive shallow leakage of lubricating grease simultaneously, thus the service life of having improved the edger roll bearing.

2, the utility model is with bearing and rolling mill edger roll position some zero, Fujian organic composition one, form a kind of independently edger roll bearing arrangement assembly, promptly simplified the structure at the edger roll of milling train position own, also be install or production line of rolling mill is top and point between the time convenient, save time.

Description of drawings

Fig. 1 is the utility model structural representation.

The specific embodiment

Reference numeral shown in Figure 1 is as follows: edging roll 1, edger roll bearing 2, lining 3, roll mandrel 4, edger roll housing 5, soket head cap screw 6, spring washer 7, seal washer 8, " V " RunddichtringO 9, " O " RunddichtringO 10, locking brill 11, locking nut 12, sunk screw 13, sealing ring 14.

In the schematic diagram of a kind of novel edger roll bearing arrangement assembly shown in Figure 1, its primary structure comprises: edging roll 1, edger roll bearing 2, lining 3, roll mandrel 4 and edger roll housing 5.Edging roll 1 and edger roll housing 5 are fixed together by special nut, edging roll 1, edger roll bearing 2 and lining 3 link together by the roll mandrel 4 that passes the edger roll bearing centre, location-plate is with nut positioning and locking lining 3, and edger roll housing 5 outer faces and nut, lining 3 external diameters are organized seal ring assembly with edger roll housing 5 and edger roll bearing 2 positiver sealings with fixing ring 10 and another respectively.Be provided with locking nut 12 between edger roll housing 5 and the edger roll bearing 2, be connected to sunk screw 13 on the locking nut 12, be provided with locking brill 11 in the periphery of sunk screw 13, and be provided with " O " RunddichtringO 10 between edger roll housing 5 and the edger roll bearing 4.Special nut is made up of soket head cap screw 6, spring washer 7 and seal washer 8, is provided with " V " RunddichtringO 9 in the junction of special nut and edger roll housing.
