Abstract
The utility model discloses a kind of flat cold-rolled sheet flattener backing roll sealing device, including O-ring sealing, bearing gland, reinforced seal, Sealing shield ring and hole back-up ring；The O-ring is sealingly disposed in the inner side of the bearing gland；The reinforced seal is located at the outside of the bearing gland, and the reinforced seal is located at the inner side of the annular outer wall of the bearing gland；The Sealing shield ring is located at the outside of the reinforced seal and the bearing gland, and the hole is located at the outside of the Sealing shield ring with back-up ring.This utility model can improve the effect of sealing, it is ensured that backing roll does not operationally have oil seepage spilling, it is to avoid the oils and fatss of spilling are bonded in plate face after meeting water emulsification, it is ensured that the cleanliness factor of plate face.
Description
Technical field
This utility model is related to a kind of flat cold-rolled sheet straightener, specifically, is related to a kind of flat cold-rolled sheet flattener backing roll
Sealing device.
Background technology
Steel industry flat cold-rolled sheet straightener includes support roller, intermediate calender rolls, working roll, backing roll band bearing, intermediate calender rolls and
Working roll does not have bearing, support force to act predominantly on backing roll, and this is accomplished by backing roll will larger bearing capacity, therefore
Back-up roll bearing is typically using multiple row needle bearing or multirow roller beaing, and needs good lubrication to meet its requirement.
But after aligning, plate surface must be clean, and this requires that lubricant grease can not be revealed in backing roll, will otherwise cause
The generation of waste product, this require the good sealing and wearability of backing roll sealing.
Utility model content
The technical problem solved by this utility model is to provide a kind of flat cold-rolled sheet flattener backing roll sealing device, improves
The effect of sealing, it is ensured that backing roll does not operationally have oil seepage spilling, it is to avoid water emulsification met by the oils and fatss of spilling
After be bonded in plate face, it is ensured that the cleanliness factor of plate face.
Technical scheme is as follows：
A kind of flat cold-rolled sheet flattener backing roll sealing device, including O-ring sealing, bearing gland, reinforced seal, sealing gear
Circle and hole back-up ring；The O-ring is sealingly disposed in the inner side of the bearing gland；The reinforced seal is located at the bearing gland
Outside, and the reinforced seal be located at the bearing gland annular outer wall inner side；The Sealing shield ring is located at described
Reinforced seal and the outside of the bearing gland, the hole are located at the outside of the Sealing shield ring with back-up ring.
Further：The O-ring sealing, the bearing gland, the reinforced seal, the Sealing shield ring and hole gear
The center of circle of circle is located on same axis.
Further：The hole back-up ring is placed in the cannelure of supporting roll body.
Compared with prior art, this utility model technique effect includes：
1st, the sealing structure form of original backing roll is changed by this utility model, improves the effect of sealing, it is ensured that
Backing roll does not operationally have oil seepage spilling, it is to avoid the oils and fatss of spilling are bonded in plate face after meeting water emulsification, protects
The cleanliness factor of plate face has been demonstrate,proved, product quality has been improve, while ensure that the recoverable amount of lubricating oil in backing roll, backing roll has been reduced
The damage of bearing, improves backing roll service life, reduces the generation of accident.
2nd, this utility model solves the phenomenon that cooling water enters backing roll internal emulsification oils and fatss, reduces back-up roll bearing
Damage amount, reduces the generation of accident.
3rd, this utility model reduces the requirement on machining accuracy of bearing gland and roll body mating surface, facilitate bearing, sealing
Dismounting, saves the repair time of roller.
Description of the drawings
Fig. 1 is the use state figure of flat cold-rolled sheet flattener backing roll sealing device in this utility model.
Specific embodiment

The scope of protection.
As shown in figure 1, being the use state figure of flat cold-rolled sheet flattener backing roll sealing device in this utility model.
The structure of flat cold-rolled sheet flattener backing roll sealing device includes：O-ring sealing 4, bearing gland 5, reinforced seal 6,
Sealing shield ring 7, hole back-up ring 8；O-ring sealing 4 is arranged on the inner side of bearing gland 5, and reinforced seal 6 is located at the outer of bearing gland 5
Side, and reinforced seal 6 is located at the inner side of 5 annular outer wall of bearing gland；Sealing shield ring 7 is located at reinforced seal 6 and bearing gland 5
Outside, hole with back-up ring 8 be located at Sealing shield ring 7 outside.
O-ring sealing 4, bearing gland 5, reinforced seal 6, Sealing shield ring 7, hole are located at same axis with the center of circle of back-up ring 8
On, and it is sleeved on the end of supporting roll shaft 1.Hole back-up ring 8 is placed in the cannelure of supporting roll body 3.Bearing 2 is arranged on and props up
On runner axle 1, bearing 2, supporting roll shaft 1 are inside supporting roll body 3.
Moreover, it will be appreciated that although this specification is been described by according to embodiment, not each embodiment is only wrapped
Contain an independent technical scheme, this narrating mode of description is only that those skilled in the art should for clarity
Using description as an entirety, the technical scheme in each embodiment can also form those skilled in the art through appropriately combined
Understandable other embodiment.
