Background technology
In seamless steel pipe hot-rolling was produced, the hollow forging after tube rolling extends is general to become hot production tube through behind fixed, tube reducing unit rolling.The kind of drive fixed, reducing mill has two kinds, and the one, differential gearing realizes that by a main motor and Overlap electric machine and planetary reducer the roll of fixed, each roll stand of tube reducing unit is according to the speed running of setting.When the seamless steel pipe of rolling heavy caliber, thick-walled pipe, the differential gearing mode generally seldom adopts, but adopts second kind the independent kind of drive.Each roll stand is driven separately by a motor, drives each roll stand by a public main gear reducer.But it is huge that this independent kind of drive exists the main gear reducer structure, processing, assembling, transportation, installation cost height and the big problem of difficulty.
Summary of the invention
The invention solves when the seamless steel pipe of rolling heavy caliber, thick-walled pipe, the public main gear reducer structure in the individual drive of fixed, the reducing mill that is adopted is huge, processing, assembling, transportation, installation cost height and the big problem of difficulty.
The present invention is achieved by the following scheme:
The transmission device of reducing mill calmly,, comprise main motor, reductor, shaft coupling, roll stand, wherein flatly roll main motor 1 and be connected with the flat reductor 3 that rolls of an independent transmission by shaft coupling 2, flat two output shafts that roll reductor 3 respectively are connected with a universal-joint spindle 4, and each universal-joint spindle 4 links to each other with a roll mandrel in the roll stand 5; Rolling on edge master motor 8 is connected with the rolling on edge reductor 6 of an independent transmission by shaft coupling 9, and two output shafts of rolling on edge reductor 6 respectively are connected with a universal-joint spindle 10, and each universal-joint spindle 10 links to each other with a roll mandrel in the roll stand 7.
The power shaft 18 of described rolling on edge reductor 6 is exported two output shafts 23 and 24 that rotating speed is the same by the gear reduction transmission device, and power shaft 18 and output shaft 23,24 one-tenth an angle of 90 degrees.Described speed reduction gearing can be power shaft 18 successively by one-level Bevel Gear Transmission 19, second level helical gear transmission 20, and third level helical gear transmission 21, fourth stage helical gear transmission 22, two output shafts 23 and 24 that rotating speed is the same of output slow down.
The transmission device of described fixed, reducing mill, the wherein said flat power shaft 11 that rolls reductor 3 is exported two output shafts 12 and 13 that rotating speed is the same by the gear reduction transmission device.Described gear reduction transmission device can be power shaft 11 by first order helical gear transmission 14, second level helical gear transmission 15, third level helical gear transmission 16, fourth stage helical gear transmission 17, slow down and export two output shafts 12 and 13 that rotating speed is the same, wherein first order transmission 14 becomes 90 degree with second level transmission 15 transmission direction.
The present invention improves the structure of independent transmission, become the structure of a plurality of motors by a plurality of roll stands of the independent transmission of big main gear reducer and be the structure of a plurality of motors by a plurality of roll stands of the independent transmission of a plurality of monomer reductors, it is the corresponding one by one transmission of motor, reductor, roll stand, make transmission device simple in structure of fixed, reducing mill, be easy to processing, assembling, transportation, reduce cost greatly.

The specific embodiment
Fixed, the independent transmission system of tube reducing unit mainly consists of the following components: main motor, monomer reductor, shaft coupling, roll stand.A main motor is by monomer reductor of shaft coupling transmission, and this monomer reductor is realized the speed operation of roll to set again by two roll mandrels in the universal-joint spindle dummy roll frame.
The flat embodiment that rolls: main motor 1 is by the flat reductor 3 that rolls of shaft coupling 2 transmissions, and the flat reductor that rolls is again by flat two roll mandrels that roll sizing mill 5 roll stands of two universal-joint spindle 4 transmissions.The wherein flat reductor 3 that rolls is exported two output shafts that rotating speed is the same by a power shaft through level Four helical gear transmission deceleration, makes foldable structure in order to save the space.
The rolling on edge embodiment: main motor 1 is by shaft coupling 2 transmission rolling on edge reductors 6, and the rolling on edge reductor passes through two roll mandrels of universal-joint spindle 10 transmission rolling on edge sizing mills 7 roll stands again.Wherein the rolling on edge reductor power shaft is by one-level Bevel Gear Transmission and two output shafts that rotating speed is the same of three grades of helical gear transmissions deceleration output, and input and output shaft becomes 90 ° of layouts.
