Abstract

The utility model discloses a sealing device for a high-speed gear box of a rolling mill. The sealing device comprises a sealing ring, a sealing ring holder and a sealing roll ring, wherein, the sealing ring comprises an annular main body, an annular framework and a sealing lip which is manufactured into a whole with the annular main body, wherein, the sealing lip and the annular main body are arranged in the radial cross section of the sealing ring and present a V shape, the sealing lip extends out slanchwise along the centrifugal direction of the sealing ring, a sealing groove matched with a annular main body base is arranged on the sealing ring holder, and a V-shaped angle a can ensure that the distance b between the end part of the sealing lip and the annular main body base is 1.5 mm to 3 mm larger than the distance b 1 between the annular main body base and the sealing end surface of the sealing roll ring. The sealing device can reasonably define the tension force after the installation, thus the sealing effect is achieved while the abrasion of the sealing lip can be greatly alleviated, the service life of the sealing ring is prolonged, and the sealing device can effectively ensure that water or other foreign material can not enter into the gear box, therefore, the operation period of the device is prolonged, the frequency of maintenance is reduced, and the maintenance cost is reduced.

Description

Milling train high gear box seal device
Technical field
The utility model relates to a kind of sealing component, particularly a kind of milling train high gear box seal device.
Background technique
Milling train gear-box sealability is the necessary factor in decision roll mandrel and bearing working life.Gear-box water inlet and other impurity are the main causes that cause bearing lubrication deterioration of oil and bearing and roll mandrel wearing and tearing.The gear-box seal arrangement can effectively prevent gear-box water inlet and other impurity.In the prior art, the seal arrangement of milling train gear-box comprises seal ring, packing holder and sealing collars, sealing lip and annular body are the V-shape setting in the radial cross section of seal ring, seal ring is contained in the seal groove of packing holder, seal action is played in sealing lip and sealed roller loop contacts and relative movement.Because sealing lip V-shape angle is bigger, therefore, sealing lip and sealed roller loop contacts backward pull are bigger, it is bigger to rotate back frictional force, cause sealing lip to wear and tear fast, thereby destroy the sealability of seal arrangement, cause the water inlet of lubricant oil station, make bearing lubrication liquid rotten, the accelerating gearbox internal corrosion, thus quicken bearing and roll mandrel wearing and tearing, and influence is produced and is normally carried out, increase frequency of maintenance, thereby increase maintenance cost.Simultaneously, in the prior art, the sealing lip thinner thickness, bulk deformation is serious behind the frictional heat, influences sealing effect.
Therefore, need a kind of milling train gear-box seal arrangement, can effectively seal, the extension fixture operation period, reduce frequency of maintenance, thereby reduce the operation and the cost of overhaul gear-box.
The model utility content
The purpose of this utility model is to provide a kind of milling train high gear box seal device, can effectively seal the gearbox output shaft place, and extension fixture service life reduces frequency of maintenance, thereby reduces operation troubles, and reduces maintenance cost.
Milling train high gear box seal device of the present utility model, comprise seal ring, packing holder and sealing collars, described seal ring comprises annular body, cyclic skeleton and makes the sealing lip of one with annular body, sealing lip and annular body are the V-shape setting in the radial cross section of seal ring, and sealing lip stretches out along the seal ring centrifugal direction is oblique; The seal groove that matches with the annular body base is set on the packing holder, and the angle [alpha] assurance sealing lip end of described V-shape and the distance b between the annular body base are than the distance b 1 big 1.5-3mm of annular body base with sealing collars seal face.
Further, described sealing lip thickness is 1.5-2mm;
Further, the distance b the when angle of described V-shape guarantees to install between sealing lip end and the annular body base is than the distance b 1 big 2mm of annular body base with sealing collars seal face, and described sealing lip thickness is 1.5mm;
Further, described annular body base radial width c guarantees when mounted the seal groove radial width c1 consistent size with the milling train packing holder;
Further, the material of described packing holder is a stainless steel.
Milling train high gear box seal device of the present utility model, regulate seal ring V-shape angle, rationally set the tension force after installing, can slow down the wearing and tearing of sealing lip when reaching sealing effect greatly, prolong seal ring working life and effectively guarantee and do not intake and other impurity in the gear-box, thereby the extension fixture operation period reduces frequency of maintenance, reduces the operation and the cost of overhaul; Sealing lip thickness is adjusted, increased intensity, be difficult for deforming, further guarantee sealing effect; Annular body base radial width and seal groove radial width consistent size guarantee to install and stablize, and coaxality does not depart from during operation, guarantees sealing effect; The material of packing holder is a stainless steel, effectively opposing corrosion, and the planeness of maintenance installation surface is installed accurately seal ring, guarantees sealing effect.
Description of drawings
Below in conjunction with accompanying drawing the utility model is described further.
Fig. 1 is the utility model cross-sectional view;
Fig. 2 is the utility model seal ring cross-sectional view.
Embodiment
It is 7mm with the distance that seals the collars seal face that back annular body base is installed in the present embodiment, and the seal groove radial width of packing holder is 10.5mm.
Fig. 1 is the utility model cross-sectional view, Fig. 2 is the utility model seal ring cross-sectional view, as shown in the figure: milling train high gear box seal device of the present utility model, comprise the seal ring 1 of oil resistant rubber material, the packing holder 2 and the sealing collars 3 of stainless steel, seal ring 1 comprises annular body 11, cyclic skeleton 14 and makes the sealing lip 12 of one with annular body 11, sealing lip 12 is the V-shape setting with annular body 11 in the radial cross section of seal ring 1, and sealing lip 12 is along oblique the stretching out of seal ring 1 centrifugal direction; The seal groove 21 that matches with annular body base 13 is set on the packing holder 2, angle [alpha] assurance sealing lip 12 ends of V-shape and the distance b between the annular body base 13 just are 9mm than the distance b 1 big 2mm of shape main body base 13 with sealing collars 3 seal faces; Sealing lip 12 thickness are 1.5mm; Annular body base 13 radial width c guarantee consistent with the seal groove 21 radial width c1 of packing holder 2 when mounted, are 10.5mm.
In the practice, distance b between sealing lip 12 ends and the annular body base 13 is not limited to 2mm than the distance b 1 big numerical value of shape main body base 13 and sealing collars 3 seal faces, difference according to key dimension, can be any numerical value in the 1.5-3mm scope, can both realize the model utility purpose; If size less than 1.5mm, does not then reach sealing effect, greater than 3mm, it is bigger that backward pull is installed, and the aggravation wearing and tearing do not have required sealing effect.Sealing lip 12 thickness are not limited to 1.5mm, also can be any numerical value of 1.5-2mm, less than 1.5mm, easily deform, and greater than 2mm, then waste material and resiliently deformable are poor, influence sealing effect.
Explanation is at last, above embodiment is only unrestricted in order to the explanation the technical solution of the utility model, although the utility model is had been described in detail with reference to preferred embodiment, those of ordinary skill in the art is to be understood that, can make amendment or be equal to replacement the technical solution of the utility model, and not breaking away from the aim and the scope of technical solutions of the utility model, it all should be encompassed in the middle of the claim scope of the present utility model.
