Technical field
The utility model belongs to sheet material rougher of hot strip mill machine equipment, particularly a kind of roll change transmission device that the roller gear diversion mechanism is housed.
Background technology:
The transmission device of large-sized sheet material rougher of hot strip mill machine work roll changing machine is at present, tapered cylindrical gear-box of Motor Drive, this gearbox output shaft is a dual output, be rigidly connected with measure-alike pin gear, the power of motor is passed to pin gear by gear-box like this, makes its synchronous rotation.Whole transmission device is installed on the car body of roll changing carriage.And at the installed inside two row pin racks of ground roll changing carriage tracks, be meshing with each other with the pin gear position is corresponding on the car body, the driving roll changing carriage by motor can be along the roll center line like this, pulls out roll or roll is pushed in the milling train from milling train.In former transmission device, gear-box adopts the horizontal driving first order of motor conical gear pair, realizes bigger gearratio by the auxiliary driving of level Four roller gear again.The gear-box volume and the weight of this type of belt drive are bigger, take the bigger space of roll changing carriage car body; Secondly the lubricated higher oil level of oil sump makes that the sealing effectiveness of lower gearbox portion is not good, and especially the output shaft center line is positioned at below the gear-box mounting plane, causes lower box composition surface sealing effectiveness very poor; Moreover output shaft is arranged in lower margin and holds cantilever position below the plane closing, because load is very big, the accident of weld cracking between output stage bearing block and lower margin takes place in actual the use.
Summary of the invention
The utility model is intended to the shortcoming and defect part that exists in above-mentioned technology, transmission configuration is reasonable and provide not only, compact conformation, and it is big both to have transmitted moment of torsion, and gearratio is big again; And have take up room little, stable drive, easy to maintenance, low cost of manufacture and manipulate a kind of very easily roll change transmission device that the roller gear diversion mechanism is housed.
The purpose of this utility model is to adopt following technical scheme to realize: the described roll change transmission device that the roller gear diversion mechanism is housed, comprise that symmetry is loaded on two pin racks of roll change car body, it is characterized in that: with the roll change transmission device of installing roller gear diversion mechanism on the corresponding roll change car body in two pin rack positions, the roll change transmission device of described roller gear diversion mechanism is by motor, shaft coupling, worm gear case, worm screw, worm gear splined shaft and roller gear part flow arrangement are formed, motor is connected by the input of the worm screw in shaft coupling and the worm gear case, its worm and wheel is meshed, the middle part symmetry connects an end of two splined shafts in the spline axis hole of this worm gear, another gear shaft terminal of two splined shafts all stretches outside the connecting plate of worm gear case both sides, two identical roller gear part flow arrangements of symmetry installing physical dimension on two spline shaft gear ends, described each roller gear part flow arrangement is mainly by end cap, pin gear, bracing frame, idler gear, bolster and side supporting seat are formed, the connecting pin gear is formed a roller gear casing between two end cap, the outside tooth of described pin gear is meshed with pin rack, is provided with ring gear in the pin gear; An end that on the connecting plate lateral surface, connects bracing frame, the other end of bracing frame passes the roller gear casing and stretches outside casing and be connected in the side supporting seat, be evenly equipped with three idler gears on the described bracing frame, one side of described each idler gear is meshed with the ring gear of pin gear, and the opposite side of this each idler gear is meshed with the gear end of splined shaft.
Described each connecting plate is connected on the lateral surface of worm gear case by bolt.
Described each idler gear is sleeved on the back shaft of bracing frame.
Principle of the present utility model and operation are described below:
The utility model adopts the two-stage gear drive: the transmission of first order worm and gear; Second level roller gear shunting transmission.Motor spreads out of through the splined hole of worm-gears power by the worm gear center by the worm screw in the transmission of the shaft coupling driving first order, finishes the transmission of first order big speed ratio.Two structures of worm gear internal splined hole symmetry installing and the identical second level of size roller gear part flow arrangement, described each roller gear part flow arrangement mainly is made up of end cap, pin gear, bracing frame, idler gear, bolster and side supporting seat; Wherein the spline on the splined shaft is connected with the worm gear splined hole, the ring gear engagement on three idler gears and pin gear of each splined shaft, finish to about the driving of two pin gears, again through the motion of the engagement realization roll change car body of pin gear and pin rack.For reducing the size of uni-drive gear box, characteristic and diameter dimension according to pin gear output, column gear transmission level design mix is streamed, be splined shaft while and three uniform idler gears engagements, and three idler gears simultaneously again with pin gear on the ring gear engagement, realization can be divided into the power of roller gear transmission three streams like this and converge at ring gear the driving of pin gear, has reduced the bulk of uni-drive gear box greatly.The idler gear core is equipped with rolling bearing and back shaft, bolster is installed in respectively in three axis holes of bracing frame, one end of bracing frame is connected with the worm gear case bolt by connecting plate, and the other end and side supporting seat are rigidly connected, and are fixed on jointly on the car body of roll changing carriage.Splined shaft rotation during work drives three idler gear rotations, because idler gear is assemblied on the fixing bracing frame, such three intermediate gear drives ring gears rotate, thereby realizes the driving to pin gear.For fully reaching the evenly effect of shunting of power, between idler gear endoporus and housing washer, leave small gap, this gap forms oil film during transmission device work, and the oil film thickness strain can make idler gear all carry.The comprehensive above technical scheme of being taked realizes the purpose of this utility model.
Compared with prior art, characteristics of the present utility model are:
1, because the utility model adopts the two-stage gear drive: the transmission of first order worm and gear; Second level roller gear shunting transmission.Motor spreads out of through the splined hole of worm-gears power by the worm gear center by the worm screw in the transmission of the shaft coupling driving first order, finishes the transmission of first order big speed ratio.Characteristic and the diameter dimension in the roller gear part flow arrangement of the second level, exported according to pin gear, column gear transmission level design mix is streamed, be splined shaft while and three uniform idler gears engagements, and three idler gears simultaneously again with pin gear on the ring gear engagement, realization is to the driving of pin gear, the power of roller gear transmission can be divided into three streams like this and converge, reduce the bulk of uni-drive gear box greatly at ring gear.
2, for reducing the size of uni-drive gear box, characteristic and diameter dimension according to pin gear output, column gear transmission level design mix is streamed, be splined shaft while and three uniform idler gears engagements, and three idler gears simultaneously again with pin gear on the ring gear engagement, realization can be divided into the power of roller gear transmission three streams like this and converge at ring gear the driving of pin gear, has reduced the bulk of uni-drive gear box greatly.
Therefore, the utility model not only transmission configuration is reasonable, compact conformation, and it is big both to have transmitted moment of torsion, and gearratio is big again; And have take up room little, stable drive, easy to maintenance, low cost of manufacture and manipulate characteristics such as very convenient.
