Description
Technical field
The utility model is related to a kind of multiple transmission device of milling train, and it belongs to a kind of multiple transmission of metallurgy industry milling train
Device.
Background technology
Current four-roller or the conventional kind of drive of multi-roll mill have two kinds.A kind of kind of drive is：Support roller is filled with transmission
Put connection.The support roller of this kind of drive is power roller, and working roll is driven roll, the mill milling scope of the kind of drive
Greatly, when drafts is big, roll-force is big, its working condition is good, and rolled piece quality is good；When drafts, roll-force and rolling torsion
It is small arrive certain value when, support roller drive when working roll often there is skidding, cause rolled piece galled spots, cause product quality
It is unqualified.
Another kind of drive is：Working roll couples with transmission device.The working roll of this kind of drive is power roller, branch
Support roller is driven roll, and the milling train of the kind of drive is small due to working roll driving torque, and rolling scope is small.
The content of the invention
The purpose of this utility model is that the kind of drive for solving current four-roller or multi-roll mill has working roll and often gone out
Existing skidding, there is provided a kind of multiple transmission device of milling train for the technical problem that Qualified Products Rate is low and rolling scope is small.
In order to solve the above technical problems, the technical solution adopted in the utility model is：
A kind of multiple transmission device of milling train, it includes two sets of rolling transmission devices, and a set of rolling transmission device is support
Roller drive arrangement, the support roller drive arrangement couples with support roller, for high-torque rolling；It is another set of to be driven dress for working roll
Put, the work roller drive arrangement couples with working roll, for the small torque rolling of high speed；The support roller drive arrangement includes branch
Roller, support roller power transmission shaft, the first reduction box and the first motor are supportted, the rotating shaft of the first motor and the input shaft of the first reduction box join
Connect, the output shaft of the first reduction box couples with one end of support roller power transmission shaft, the other end and the support roller of support roller power transmission shaft join
Connect；The work roller drive arrangement includes working roll, transmission shaft of working roll, the second reduction box and the second motor, the second motor
Rotating shaft couples with the input shaft of the second reduction box, and the output shaft of the second reduction box couples with one end of transmission shaft of working roll, work
The other end of roller power transmission shaft couples with working roll, working roll be located at support roller between and working roll axle center and the axle center of support roller
In same perpendicular, the second reduction gearbox output shaft in work roller drive arrangement is located at the support in support roller drive arrangement
The centre of roller power transmission shaft.
Further, the work roller drive arrangement power output for support roller drive arrangement power output 1%~
90%.
The utility model uses above-mentioned technical proposal, when realizing smaller drafts, smaller roll-force and smaller rolling torsion,
Directly driven using work roller drive arrangement, support roller is passive or follows working roll to rotate, it is to avoid Slippage between rolls cause rolled piece
The problem of galled spots；Using support roller drive arrangement when roll torque is big, working roll is passive or follows backing roll to rotate, and rolls
Scope is wide；The kind of drive for solving current four-roller or multi-roll mill has working roll and skidding, product matter often occurs
Measure the technical problem that qualification rate is low and rolling scope is small.Therefore, compared with background technology, the utility model has multiple transmission dress
Put, the product surface quality of rolled piece it is good and can driven separately also can be while the advantage being driven.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model；
Fig. 2 is Fig. 1 top view.
Embodiment
The utility model is described in further detail with reference to the accompanying drawings and examples.
As depicted in figs. 1 and 2, the multiple transmission device of the milling train in the present embodiment, it includes two sets of rolling transmission devices,
A set of rolling transmission device is support roller drive arrangement, and the support roller drive arrangement couples with support roller, rolled for high-torque
System；Another set of is work roller drive arrangement, and the work roller drive arrangement couples with working roll, for the small torque rolling of high speed.
The support roller drive arrangement includes support roller 1, support roller power transmission shaft 4, the first reduction box 7 and the first motor 8, the first motor 8
Rotating shaft couple with the input shaft of the first reduction box 7, the output shaft of the first reduction box 7 couples with one end of support roller power transmission shaft 4,
The other end of support roller power transmission shaft 4 couples with support roller 1.The work roller drive arrangement includes working roll 2, transmission shaft of working roll
3rd, the second reduction box 5 and the second motor 6, the rotating shaft of the second motor 6 couple with the input shaft of the second reduction box 5, the second reduction box 5
Output shaft couple with one end of transmission shaft of working roll 3, the other end of transmission shaft of working roll 3 couples with working roll 2.Working roll 2
Between support roller 1 and the axle center of working roll 2 and the axle center of support roller 1 are in same perpendicular, work roller drive arrangement
In the output shaft of the second reduction box 5 be located at support roller drive arrangement in support roller power transmission shaft 4 centre, and working roll be driven
Device power output is the 30% of support roller drive arrangement power output.
When needing the small torque of high speed to roll, working roll follows working roll to rotate as power roller, support roller；It is big when needing
When torque is rolled, backing roll follows backing roll to rotate as power roller, working roll；Working roll can be also driven simultaneously with backing roll.
Work roller drive arrangement power output in above-described embodiment can also be in support roller drive arrangement power output
Chosen between 1%~90%.
