By roller gear reduction box or turbine reduction box transmission campaign, it can be used on almost all of milling train machine, such as just
Milling train, plate slab mill, heavy plate mill, sheet mill and hot plate hoop mill, cold drawing hoop mill.Its advantage is that displacement is reachable
Larger numerical value（The usual volume of molybdenum plate milling train casing is larger, belongs to massive casting structure）, speed and acceleration also can reach necessarily
Requirement, pressure ability it is larger.But its shortcoming is complicated, the reaction time is longer, less efficient.
General common screwdown gear mainly includes motor, decelerator, brake, travelling gear, housing screw, pressure spiral shell
Mother, position indicator etc., in the prior art, screwdown gear mainly carry out deceleration transmission using two gear engagements, however, actual
Speed reducing ratio is excessive during production run, have impact on the pressing speed of milling train, causes production efficiency low.On the other hand, due to
Whole casing for molybdenum plate milling train is massive casting structure, and the variation of internal structure needs to cast again, and cost is higher and casts
Cycle length is made, can not quickly be come into operation after buying back.The utility model is to provide a kind of variable ratio of reversible molybdenum plate milling train
Screwdown gear, to improve the pressing speed of milling train, improve production efficiency.
Utility model content
In order to solve above mentioned problem existing for prior art, inventor for the structure of molybdenum plate rolling mill screw down to entering
Gone system research, found to increase a gear in two current gears, and according to gear centre away from limitation, enter again
Row proportion design, so only need to carry out local directed complete set to gear and its assemble mechanism, without changing former frame cast structure, i.e.,
It can be achieved to reduce speed reducing ratio, improve transmission efficiency, and then greatly improve production efficiency, improvement cost is cheap.
Therefore, the utility model provide it is a kind of be used for molybdenum plate rolling mill screw down, the screwdown gear including frame,
Motor, gear mechanism, worm-and-wheel gear, leading screw and briquetting, the gear mechanism is by gear, idler gear, lower gear
And their own assembled shaft forms, two motor are provided with the frame, are additionally provided between described two motor
Clutch, the other end of described two motor are connected by shaft coupling with the gear in two groups of teeth wheel mechanism respectively, and
Lower gear in the two groups of teeth wheel mechanism is connected with two groups of worm-and-wheel gears respectively, between two groups of worm-and-wheel gears
Provided with balancing pole, and leading screw being connected on two groups of worm-and-wheel gears, the other end of the leading screw is provided with briquetting,
The side of one of gear is provided with displacement transducer.
Preferably, the clutch is electromagnetic clutch.
Preferably, described idler gear is fixed on the frame by idler gear assembled shaft and bearing, bearing cap
On.
Preferably, it is equipped with displacement transducer on two gears.
Using screwdown gear of the present utility model, during work, two motor in frame are driven by shaft coupling respectively
Gear is rotated, the driven rotation under engagement of idler gear and lower gear, and guide screw movement is driven by worm-and-wheel gear,
The briquetting of leading screw lower end is connected by bolt with the upper backup roll of molybdenum plate milling train, drives its motion, realizes the tune to upper roller position
It is whole, and be monitored by displacement transducer.Screwdown gear of the present utility model can be straight on the basis of original molybdenum plate milling train casing
Connect improvement to obtain, specifically, can directly add idler gear assembled shaft in the correspondence position in casting box frame, and
It is engaged with bearing, bearing cap, idler gear is set up among gear and lower gear, and adjust the size of three gears, is made
Be fully engaged, and cause casing in screwdown gear other structures keep it is constant.And the idler gear set up is advantageous to
Realize and reduce lower gear radius, significantly reduce speed reducing ratio, improve overall transmission efficiency, and then improve production efficiency, drop
Low integrated cost.
