Application of seal on oil film bearing of rolling mill and the 6700 market trend
Application of seal on oil film bearing
of rolling mill
Oil film bearing is also called liquid
friction bearing. In the process of rolling the mill, liquid lubrication is
used to form a complete pressure oil film between the cone sleeve and bushing.
The oil film completely separates the casing from the cone sleeve and runs at
relatively high speed with no direct metal contact.
A sealing device is an important part of
oil film bearing.
There are three main characteristics of
the oil film bearing rotary seal:
1) two-way medium (water or emulsion,
lubricating oil) seal
2) Pressure difference on both sides,
but jet or splash
3) The seal rotates with the roller at
The rotary seal of the oil film bearing
in the rolling mill is lip seal. Lip seal mainly depends on the tip of the
sealing lip to compress the sealing coupling surface. Theoretically, it should
be line contact, but in fact, it is narrow-band contact, with enough compression
force, contact stress is peak.
The lip seal should not be pressed too
tightly and the contact band should not be too wide. Analysis from the dual
Angle of lubrication and sealing, that is: if the pressure is too large, the
surface of the seal and coupling will be in a semi-dry friction state,
aggravating the wear and heating of the seal, shortening the service life.
If the contact zone is too wide, thicker
wax lubrication may develop, which can leak outwardly and reduce the sealing
