The shaped roll equipment of above-mentioned prior art has the following disadvantages: upper roll wheel is the passive rotation of frictional force between utilization and the shaped steel, has the phenomenon that throws switch.Because upper roll wheel and lower roll wheel adopt the same roller footpath usually, therefore bottom roll rotates a circle and drives in the shaped steel moving process, upper roll wheel can not be guaranteed to rotate a circle, and makes shaped steel rolling face be subjected to upper roll wheel, lower roll wheel roll-in degree difference, causes the rolling of sectional iron quality unstable relatively.
For overcoming above-mentioned the deficiencies in the prior art, also there is employing to drive the roll equipment of upper roll wheel and lower roll wheel rotation respectively, the structure of this equipment is: two (being power source) drives initiatively lower roll wheel and upper roll wheel rotation respectively by the universal joint bar-link drive.But this equipment exists equipment volume big, and fault is many, cost height, defective such as mechanical efficiency is low.
Summary of the invention
The objective of the invention is to overcome above-mentioned technical deficiency, provide a kind of same power source to realize that driving upper roll wheel and lower roll wheel rotate synchronously, prevent the equipment that any one running roller throws switch.
Another object of the present invention provides a kind of equipment that is driven upper roll wheel and lower roll wheel rotation by different driving mechanism respectively.
A further object of the invention provides a kind of upper roll wheel and lower roll wheel to have different rotating speeds, the equipment that makes the shaped steel after the rolling have good quality.
The technical scheme that solves the problems of the technologies described above is: a kind of double power roller speed-changing shaft-distance-changing type steel roller equipment, this double power roller speed-changing shaft-distance-changing type steel roller equipment comprises: by the active lower roller shaft of frame support and last roll shaft, power source, the double dynamical roller gear of described drive power source, one of them live roll gear is: power source directly drives the active lower roller shaft that driving gear is housed and rotates, and this driving gear drives driven gear Jie axle that driven gear is housed and rotates; Another live roll gear is: on described driven gear is situated between axle the dentition drive is housed also, this dentition drive passes to roll shaft with kinematic pair.
The invention has the beneficial effects as follows: driving gear of the present invention is identical with the driven gear engagement diameter and the number of teeth, can guarantee each unanimity of power main transmission speed.The wheelbase guiding mechanism can easily be adjusted equipment top and bottom rolls gap between roll shaft of the present invention, and is easy to use; Adjustment mechanism of tightening of the present invention can easily be adjusted the position of tensioner sprocket wheel, makes chain transmission campaign accurate, can satisfy topping roll and rotate technological requirement.The present invention has simple in structure, and volume is little, and the efficient height has overcome prior art and utilized universal joint bar-link drive equipment volume big, and fault is many, cost height, shortcoming such as mechanical efficiency is low.
