The control device has the advantages of good stability, low investment and small occupying area, and can meet the requirement of high-speed rolling.
Description
Technical field
The utility model metallurgical control equipment, particularly the double-working drive combination gear case apparatus in the hot rolling industry.
Background technology
Requirement because of rolling mill practice in the hot rolling industry often needs the output speed of upper and lower roll is adjusted separately, to prevent that stocking from upwarping or have a downwarp, in order to satisfy the traditional solution of this demand is that a motor drives a roll by a gear-box, its shortcoming is a top working roll universal-joint spindle overlength, stability of transmission is relatively poor, investment is high, and floor space is big, is difficult to satisfy the requirement of modern milling train high-speed rolling.
And in four rollers, the cold rolling industry of six rollers, its traditional structure is the two output synchronously of list input combination gear casees, and its shortcoming is that large-sized rolling mills is subjected to the restriction of standard electromotor power can only adopt nonstandard motor, and cost of investment increases, the construction period prolongation thereby make.
Summary of the invention
It is better that the purpose of this utility model provides a kind of stability, invests lowly, and floor space is little, can satisfy the double-working drive combination gear case apparatus of high-speed rolling requirement.
The purpose of this utility model is to realize like this, double-working drive combination gear case apparatus, it is characterized in that: dc speed-regulating motor is connected with two power shafts of combination gear case respectively by the duplex axial organ, two output shafts of combination gear case link to each other with upper working rolls and lower working rolls respectively by universal-joint spindle, and two cover trains drive two rolls independently separately respectively.
First power shaft and second power shaft during described combination gear case comprises on the casing; First jackshaft between upper box and middle casing and the lower box and second jackshaft, first output shaft and second output shaft; First power shaft and second power shaft mesh with first jackshaft and second jackshaft respectively, first jackshaft and second jackshaft respectively with the engagement of first output shaft and second output shaft, dc speed-regulating motor drives first output shaft and second output shaft by first power shaft and second power shaft and first jackshaft and second jackshaft.
But described two cover train single action, also linkages.
Advantage of the present utility model and effect are: owing to adopt double-working drive combination gear case respectively, 301 and 305 power shafts drive output shaft 303 and 308 respectively by jackshaft 302 and 307 during work, thereby realize the transmission purpose of dual input, dual output.Have simple in structure, compact, performance safety, reliable, small investment, floor space is little, good looking appearance, advantage such as easy to maintenance, this structure can be saved one times with traditional structure than floor space, weight can be saved more than 1/3rd.Can be used for hot rolling and cold rolling in two rollers, four rollers, six-high cluster mill in.
