Abstract
The utility model provides a rolling mill oil film bearing's oil -sealing arrangement, relates to rolling mill oil film bearing, solves sealed poor, the short -lived technical problem of effect of current oil film bearing oil -sealing arrangement. The utility model discloses by sealed lid, distance ring, sealed hoop with the foot type is sealed constitutes, the suit in the space that constitutes by taper sleeve, bush, bearing frame and roll, its characterized in that: the internal embedding elastic support skeleton of sealed limb rubber that the foot type is sealed, sealed covering and the two pass the facial position of coupling of sealed limb, bonding self -lubricating wearing layer, the sealed hole bottom of covering is add the oil trap and is led the oilhole, leads the exit linkage of oilhole and leads oil pipe, leads the oil return outlet hole department that the oil pipe export is located the bearing frame. The utility model is used for rolling mill oil film bearing's sealing device, have sealed effectual, long service life, lubricating oil leakage is little, the running cost is low, compact structure, the convenient advantage of dismouting.
Description
Technical field
This utility model relates to filmatic bearing of press, particularly to the sealing device of a kind of filmatic bearing of press,
It is more particularly to the oil-sealing arrangement of a kind of filmatic bearing of press.
Background technology
, there is leaking of lubricating oil, cause the wasting of resources in the filmatic bearing work under bad environment of hot and cold milling train
Problem with environmental pollution.At present, widely used film bearing seal device, by oil sealing and water seal two
Being grouped into, its structure is as shown in Figure 1.
Oil-sealing arrangement by sealing lid 4, distance collar 6, sealing hoop 7 and foot type seal 8 and form, be sleeved on by
In the space that tapered sleeve 1, lining 2, bearing block 3 and roll 9 are constituted；Seal lid 4 by screw and bearing
Seat 3 connects, and after sealing hoop 7 is loaded onto in foot type sealing 8, it inwardly curves crescent and loads sealing lid 4
In, distance collar 6 is sleeved on foot type and seals on 8；Water seal 5 is screwed in the outer face sealing lid 4.
The oil-sealing arrangement of existing filmatic bearing, has the disadvantage in that
1, foot type seals the sealing limb 81 of 8 is a kind of flexibility lip, because of (special by Effect of Hyperthermic Environment
It is not hot-rolling oil film bearing), along with the working time increases, the resilience of rubber bodies gradually weakens, and reduces
Sealing effectiveness, easily causes oil leak, pollutes environment and waste resource.
2, for the sealing effectiveness that holding is good, the replacement cycle that foot type seals 8 is short, and filmatic bearing is safeguarded into
This height.
Summary of the invention
The purpose of this utility model is to overcome the shortcoming of prior art, it is provided that the oil of a kind of filmatic bearing of press
Seal apparatus, solves the technical problem that existing filmatic bearing oil-sealing arrangement sealing effectiveness is poor, the life-span is short.
This utility model is achieved through the following technical solutions:
The oil-sealing arrangement of a kind of filmatic bearing of press, by sealing lid, distance collar, sealing hoop and foot type sealing group
Become, be sleeved in the space being made up of tapered sleeve, lining, bearing block and roll, it is characterised in that: described foot
The sealing limb rubber bodies that type seals is embedded in resilient support skeleton, and described sealing covers and seals described in two pass
The coupling surface position of limb, bond self-lubricating abrasion-resistant layer, and described sealing lid endoporus is additionally arranged at the bottom of oil trap and Oil Guide
Hole, the outlet of oil guiding hole connects oil guide pipe, oil guide pipe outlet be positioned at the oil return outlet opening of bearing block at.
Further, described self-lubricating abrasion-resistant layer selects PTFE class self-lubricating material, and its surface roughness is
Ra0.2～1.6.
This utility model compared with prior art, has the following advantages and beneficial effect:
(1) the seal oil limb rubber bodies that foot type seals is embedded in resilient support skeleton, solves hot environment (special
It is not hot-rolling oil film bearing) cause sealing limb resilience force deficiency problem, fully ensure that sealing limb is to sealing lid
" tracing ability ".
(2) sealing coupling surface bonding self-lubricating abrasion-resistant layer, coefficient of friction is low, extends rubber seal
Service life.
(3) close closure base portion arranges oil trap and oil guiding hole, and oil guiding hole outlet connects oil guide pipe, can be by more
The lubricating oil of Guo Shou road oil sealing limb gathers, and is directed at bearing block oil return outlet opening by oil guide pipe, reduces
The leakage rate of lubricating oil.
This utility model, for the sealing device of filmatic bearing of press, has good sealing effect, and service life is long,
Oil leak is little, and operating cost is low, compact conformation, dismounts advantage easily.
