Neck wear-and corrosion-resistant sealing device.
In order to solve the above technical problems, the filmatic bearing roll neck wear-and corrosion-resistant sealing device of the utility model, for installing
At the roll neck of filmatic bearing, the filmatic bearing is installed on roll and is set between the bearing block of roll end, the oil
Film bearing roll neck wear-and corrosion-resistant sealing device includes that sealing cover and fixed water seal, sealing cover are fixed by bolts in the bearing
On seat, fixed water seal has loaded on the body part on sealing cover and seals between the shoulder end of the roll sealing of cooperation
Limb further includes having wear ring, the wear ring have be fixed on the radial part in the roller stand shoulder end face and by radial part outside
Week cooperates along the axial part extended to form, the radial part sealing of the sealing limb and wear ring is axially bent, and further includes having entirety
Formula protects water seal, and monoblock type protection water seal is annular rubber sealing ring, is made of connected mounting ring and protective ring, installs
Ring sealing is set on the outer wall of the sealing cover, and the end of the protective ring has sealing lip, and protective ring is with the close of its end
The axial part for sealing wear ring on lip and the roll shoulder, which seals, to be cooperated.
As the improvement of the utility model, there is circumferential steel band slot on the excircle of the mounting ring, steel band slot is built-in
There is lock ring steel band.
Radially lateral bending folding extends shape for wear ring axial part periphery as a further improvement of the utility model,
At there is drip ring.
As the further improvement of the utility model, the wear ring radial part and sealing limb sealing cooperation position and
The position of axial part and the cooperation of protective ring end part seal lip seal all has ceramic layer.
Filmatic bearing roll neck wear-and corrosion-resistant sealing device using the above structure, due to being utilized in sealing cover housing setting tool
Have sealing matching relationship monoblock type protection water seal, and protective ring with the sealing lip of its end with it is wear-resisting on the roll shoulder
The axial part of ring seals cooperation, therefore axial excellent sealing can be realized, while coolant liquid and dirt can be also blocked in close
The outside of capping will not impact the bolt on sealing cover, prevent coolant liquid and dirt from penetrating into and causing close along bolt mounting holes
The situation of static seal failure is corroded and is caused in capping.There is circumferential steel band slot, in steel band slot on the excircle of the mounting ring
Equipped with lock ring steel band, water seal can be protected to be securely fixed on the outer wall of sealing cover the monoblock type；Using described resistance to
Bull ring axial part periphery can further stop to cool down after radially lateral bending folding extends to form the technical characteristic of drip ring
The infiltration of liquid and dirt；The position and axial part of the wear ring radial part and sealing limb sealing cooperation and protective ring end part seal
Lip seal cooperation position all have ceramic layer, due to ceramics have the characteristics that it is wear-resisting, corrosion-resistant and resistant to high temperature, can be further
Extend the whole service life of the utility model.
