Abstract
The utility model discloses a direct-connection-type driving system of a special rolling mill for a helical blade. The direct-connection-type driving system comprises two same motors, wherein the included angle between output shafts of the two motors is same as that between two conical mill rolls of the special rolling mill for the helical blade; the output shaft of each motor is coaxially connected with a speed reducer; the output shaft of each speed reducer is coaxially connected with one end of a universal drive shaft; the other end of the universal drive shaft is fixedly connected with one conical mill roller. The two motors are respectively used for directly driving respective conical mill rolls to rotate, so that the driving efficiency is high. The direct-connection-type driving system can be used for conveniently regulating the rotation speeds of the mill rolls and is basically free from faults.
Description
Technical field
The utility model relates to cold rolling mill equipment, specifically with cold rolling process, processes the transmission system of helical blade special rolling mill.
Background technology
Helical blade cold-rolling mill is with the equipment of steel continuous rolling blade, and it,, by adjusting the skew, feeding height, rolloff pressure, directive wheel etc. of a pair roller of milling train, can roll out the blade of needed all size.The roll of conventional a pair of taper relatively rotation rolls, and helical blade is made in continuous cold rolling moulding.The roll of a pair of taper all has larger inclination angle with horizontal plane, and is installed in main spindle box, and the conical upper of roll is stretched out outside main spindle box.
Traditional helical blade special rolling mill generally adopts single motor, by mechanical variable speed device and transfer gear, drives a pair of cone-shaped roll opposite direction rotating to roll steel band simultaneously, completes the operations for forming of helical blade.Because a pair of cone-shaped roll has certain angle each other, in transfer gear, drive two power transmission shafts of a pair of cone-shaped roll rotation to be connected and coaxial rotating with corresponding cone-shaped roll, between two power transmission shafts, also there is certain angle, so, the power of motor output is after mechanical variable speed device and transfer gear transmission, by two power transmission shafts with certain angle, exported, produce a minute force phenomenon, transmission efficiency is not high.
Summary of the invention
The purpose of this utility model is to propose in order to overcome the not high defect of transmission efficiency of existing helical blade special rolling mill transmission system the helical blade special rolling mill associated mode transmission system that a kind of transmission efficiency is high.
The technical solution adopted in the utility model is: comprise two identical motors, angle between two cone-shaped rolls of the angle between two motor output shafts and helical blade special rolling mill is identical, each motor output shaft all coaxially connects a reductor, each speed reducer output shaft all coaxially connects a universal drive shaft one end, and each universal drive shaft other end is all fixedly connected with a cone-shaped roll.
A pair of cone-shaped roll is not only driven by same motor, but by two motors respectively direct-drive cone-shaped roll separately rotate, associated mode transmission, transmission efficiency is high.Can regulate easily roll rotational speed, simple in structure, operate steadily, transmission link is few, and basic fault-free, has reduced the shutdown loss causing because of transmission fault.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
In figure: 1. cone-shaped roll; 2. steel band workpiece; 3. main spindle box; 4. frame; 5. spline housing; 6. universal drive shaft; 7. axle sleeve; 8. reductor; 9. motor.
The specific embodiment
Referring to Fig. 1, the utility model helical blade cold-rolling mill has two cone-shaped rolls 1, two cone-shaped rolls 1 are arranged in main spindle box 3, main spindle box 3 is fixed in frame 4, between two axis of two cone-shaped rolls 1, there is certain angle and opposite direction rotating, the conical upper of two cone-shaped rolls 1 is stretched out outside main spindle box 3, and is steel band workpiece 2 between the conical upper of two cone-shaped rolls 1, rolls out the blade of needed all size by the opposite direction rotating of two cone-shaped rolls 1.
The opposite direction rotating motion of two cone-shaped rolls 1 drives opposite direction rotating by the utility model helical blade special rolling mill associated mode transmission system.The utility model helical blade special rolling mill associated mode transmission system comprises that the angle between the output shaft of 9, two motors 9 of two identical motors is identical with the angle between cone-shaped roll 1.The output shaft of each motor 9 all coaxially connects a reductor 8, and on the output shaft of reductor 8, cover has axle sleeve 7.The output shaft of each reductor 8 all coaxially connects universal drive shaft 6 one end, and the other end of each universal drive shaft 6 is all fixedly connected with a cone-shaped roll 1.The junction cover of the other end of universal drive shaft 6 and cone-shaped roll 1 has spline housing 5, by spline housing 5, universal drive shaft 6 and cone-shaped roll 1 is combined as a whole.On the output shaft of reductor 8, be fixed with axle sleeve 7.
The other end of universal drive shaft 6 connects the flange face of spline housing 5 with bolt, one end of universal drive shaft 6 is connected and fixed on the flange face of the axle sleeve 7 on reductor 8 outputs; 9, motor is directly fixed on reductor 8, so just makes whole system just be simplified to reductor 8 parts and these two critical pieces of universal drive shaft 6 parts of translator 9.
Start two motors 9 simultaneously, make two motors 9 drive two cone-shaped roll 1 opposite direction rotatings, by two motors 9, directly drive cone-shaped roll 1 rotation separately to roll steel band workpiece 2.
