Description
Technical field
The utility model is related to a kind of operation roll of mill driving side oil-air lubrication pedestals for cold rolling mill, belong to machine
Lubrication technical field.
Background technology
Oil-air lubrication is a kind of novel lubrication technology, it has compared with traditional fluid fluid lubrication technology without comparable
Quasi- superiority is particularly suitable for high temperature, heavy duty, high speed, extremely low speed and has the operating modes such as cooling water and foul intrusion oil site
The occasion of inclement condition, fuel consumption is extremely small, and lubricating oil utilization rate is the following cold-rolling mill roll bearing lubrication close to 100%
Main trend.
What the journal bearing of the operation roll of mill of cold rolling mill used is exactly oil gas lubricating system, which is driven by working roll
Dynamic side oil-air lubrication pedestal is fixedly connected with rack, during actual use is found, there are following for existing oil-air lubrication pedestal
It is insufficient：
One, oil-air lubrication pedestal is only connect by fixing bolt with rolling-mill housing, during the work time due to fixing bolt
It is subjected to larger repeated stock power, therefore easily loosens or is broken, and then leads to the Centre position deviation of male connector quick coupling,
Oil gas can not be successfully the operational reliability that oil gas lubricating system is reduced into bearing block.
Two, the rocking arm fastening bolt of existing oil-air lubrication pedestal can only be dismounted from front, and milling train driving side oil-air lubrication
There is spindle nose locking device in front of pedestal, is difficult to take out after fastening bolt fracture, maintenance personal can only since operating space is narrow
One is made and unsighted by hand, therefore dismounting rocking arm is required for expending or so 4 hours every time, greatly reduces the inspection of equipment
Repair efficiency.
Utility model content
The purpose of this utility model is that for the drawback of the prior art, a kind of dissection type oil-air lubrication pedestal is provided, with
The maintenance difficulty for reducing equipment, improves the overhaul efficiency of equipment.
Problem described in the utility model is realized with following technical proposals：
A kind of dissection type oil-air lubrication pedestal, composition include rocking arm, gland, axis pin and two and half copper sheathings, the axis pin
The bearing pin mounting hole be inserted into rolling-mill housing of one end in and by being fixedly connected with rolling-mill housing close to the ring flange at the end, pin
The other end of axis is equipped with position-arresting disk；Two and half copper sheathings are located between the ring flange and position-arresting disk of axis pin and are symmetrically coated on axis pin
Both sides；Oil gas lubricating system is fixed in one end of the rocking arm, and two and half copper sheathings are pressed in the groove of the rocking arm other end by the gland
The interior and fastening bolt by being parallel to rocking arm is connect with rocking arm.
The both ends outside of above-mentioned dissection type oil-air lubrication pedestal, two and half copper sheathings is equipped with semi-circular boss, the gland
With the seam allowance to match with the semi-circular boss on half copper sheathing is equipped on rocking arm.
The ring flange of above-mentioned dissection type oil-air lubrication pedestal, the axis pin is fixed on milling train machine by 3~4 positioning bolts
It is connect on frame and by welding manner with rolling-mill housing.
The rocking arm of the utility model is connect by gland and half copper sheathing with axis pin, is shaken between gland and rocking arm by being parallel to
The advantages of fastening bolt of arm connects, this split type structure, which is parts, to be dismounted from the side of lubrication pedestal, torn open
Dress operation is not limited by spindle nose locking device, and this reduces the maintenance difficulty of equipment, improve the overhaul efficiency of equipment.
The axis pin of this oil-air lubrication pedestal not only can guarantee it using being welded again with rolling-mill housing after 3~4 bolt positioning
Cylindrical surface is vertical with rolling-mill housing, and considerably increases the impact strength of axis pin, to improve oil gas lubricating system
Operational reliability.

Specific implementation mode
The utility model provides a kind of novel subdivision formula oil-air lubrication pedestal, can avoid axis pin fixing bolt and is broken thing
Therefore while use dissection type rocker structure, and the position of rocking arm fastening bolt is placed on side, avoids spindle nose locking device
To dismounting the influence of fastening bolt, the repair time is greatly saved.
Referring to Fig. 1~Fig. 9, the utility model includes mainly rocking arm 1, gland 2, axis pin 3 and two and half copper sheathings 4.Axis pin 3
One end is mounted in the former bearing pin mounting hole of rolling-mill housing, firm welding after being positioned by positioning bolt.Two and half copper sheathings 4
In the groove for imbedding gland 2 and rocking arm 1 respectively.The ear mount 6 of 2 both sides of rocking arm 1 and gland is connected using fastening bolt 11,
It is installed on axis pin 3.The axis pin 3 of this oil-air lubrication pedestal is used as non-wearing detail, is fixed on the rack for a long time.Once 1 pine of rocking arm
Move half copper sheathing 4 of replaceable two panels.The utility model avoids the problem of axis pin fastening bolt easy fracture in former design, also by rocking arm
Two parts are split into, fastening bolt 11 becomes being mounted laterally, and increases maintenance activity space, greatly reduces oil-air lubrication pedestal
Repair time and hand labor intensity.
There has also been larger improvement for the structure of axis pin 3, ensure its cylindrical surface and rolling-mill housing after being positioned using 3~4 bolts
Vertically, it is welded later along 9 periphery of ring flange, axis pin 3 and welding machine frame is integral.
Two and half copper sheathings 4 are embedded in respectively in the groove of gland 2 and rocking arm 1, and the position-arresting disk 8 on axis pin 3 can prevent half bronze medal
Set 4 falls off.Semi-circular boss 5 on half copper sheathing 4 is matched with the seam allowance 7 on gland 2 and rocking arm 1, plays the role of axially position.
