Description
Technical field
The present invention relates to a kind of milling train CVC roll shiftings coupling mechanism sealing device, belong to board rolling equipment technical field.
Background technology
In cold rolled sheet rolling, cold rolling mill typically realizes the control of template using the six continuous convexitys of roller CVC.It is cold rolling
Milling train is inevitably produced axially in the operation of rolling under the effect of the resultant force such as bending roller force and roll deformation on roll
Huge component, and four-row tapered roller bearing is used on intermediate calender rolls roll, the bearing can bear very big radial load but not
It can bear excessive axial force, therefore axial thrust load relies primarily on that the coupling locking of CVC intermediate calender rolls is in-house to be pushed away in the operation of rolling
Power self-aligning roller bearing is born；Fig. 1 is existing CVC roll shiftings coupling mechanism schematic diagram, because self-aligning thrust roller bearing has 0
~ 2 ° of aligning angle, so having 0 ~ 2 ° of eccentric angle between coupling inner sleeve and bearing block, coupling inner sleeve is calculated by similar triangles
Full swing distance be 11.63mm, then the swing due to axial 11.63mm in the operation of rolling will be caused under reinforced seal
Half part is extruded damage and top half has gap；Have 1mm's between self-aligning thrust roller bearing and bearing block simultaneously
Gap, can offset theoretical centerline 2mm with coupling inner sleeve maximum equivalent to intermediate calender rolls, further damage reinforced seal；Thrust
There is certain pressure in the thin oil lubricant that self-aligning roller bearing is used, lubricating system, reinforced seal, which is damaged, causes lubricating oil to be let out in itself
Leakage, the consumption of increase grease and financial cost；Milling train needs emulsion to cool down and lubricate roll in the operation of rolling, due to bone
Frame bad seals and gap presence will cause part emulsion to enter CVC coupling mechanism internal contamination greases, cause insufficient lubrication,
Make the self-aligning thrust roller bearing lost of life more than 6 months or even bearing locking situation occur.
