The utility model content
The purpose of this utility model is: little for relative spacing between present adjacent two milling train gear-boxes, there are error in the independent input motor rated speed and the actual speed that are not easy to install on adjustment and maintenance, every the gear-box, cause adjacent rollers mill speed coupling that error is arranged, the series of problems such as influence of rolled precision provide the shared power gear box of adjacent rollers group in a kind of new milling train.
The purpose of this utility model is achieved in that the power gear box that the adjacent rollers group shares in a kind of milling train, comprise intermeshing driven in synchronism gear and synchronous driven gear on casing, power shaft, reducing gear wheel shaft, deceleration gear wheel, output gear wheel, a pair of synchronous output shaft and the synchronous output shaft, it is characterized in that:
A) the power shaft both sides are the drive shaft system of symmetrical configuration, drive shaft system by be fixedly mounted on driving pinion on the power shaft, one-level reduction gearing axle and a pair of synchronous output shaft form at least, the reducing gear wheel shaft is all parallel with power shaft with a pair of synchronous output shaft, they all by bearings on casing, wherein, power shaft is on the same level with the axis that is positioned at the reducing gear wheel shaft of both sides, and the axis of a pair of synchronous output shaft is on the same vertical plane;
B) two driving pinions of fixed installation on the power shaft, deceleration gear wheel of fixed installation on the reducing gear wheel shaft, fixedly mount simultaneously an output gear wheel and a driven in synchronism gear on the output shaft in a pair of synchronous output shaft, synchronous driven gear of fixed installation on another output shaft;
C) two driving pinions on the power shaft respectively with the engagement of the deceleration gear wheel of both sides, reducing gear wheel shaft and the engagement of output gear wheel, driven in synchronism gear and synchronously driven gear engagement; Or two driving pinions on the power shaft respectively with the engagement of the primary speed-down gear wheel of both sides, after reducing gear wheel shafts at different levels sequentially slow down, by final reduction gear axle and the engagement of output gear wheel, driven in synchronism gear and synchronously driven gear engagement;
D) power shaft one end stretches out casing, and the synchronous output shaft of two couple of power shaft both sides all stretches out casing.
In the utility model: it is opposite that two driving pinions in the power shaft are provided with rotation direction, the close helical teeth of spiral angle.
The utility model has the advantage of: because adjacent twice rolling process is adopted a shared gear-box, not only reduced transmission mechanism at the production line of rolling mill longitudinal space, enlarged relative spacing between the gear-box, be more conducive to installation adjustment and maintenance to gear-box; Also a power shaft is accurate to be determined the forward and backward operation output mill speed relation of gear-box (speed ratio) because it shares, and design provides reliable movement relation to guarantee to rolling parameter, thereby has improved rolling accuracy.The utility model compact conformation, manufacturing cost is relatively low.
