The present invention solves its technical problem and realizes through following technical scheme:
A kind of three-roller type steel rolling mill pressuring upper device assembly; By assembly shell, housing bottom, press nut, press leading screw, high speed pinion, middle idle wheel, spline gear, brief biography moving axis form; The housing bottom is packed in below the assembly shell and with the assembly shell bottom and constitutes gear-box jointly; Press nut and be packed in the assembly shell internal upper part, press leading screw top and be rotatably installed in and press in the nut, the bottom is plugged in the spline gear; High speed pinion, middle idle wheel, spline gear all rotate to be installed in the gear-box and also are connected with a joggle successively, and brief biography moving axis bottom is rotatably installed on the gear-box and with the high speed pinion and installs mutually.
And; Said assembly shell is made up of upper shell, lower house, and upper shell, lower house branch are made as one up and down; Lower house internal cavity and housing bottom are combined to form gear-box; Upper shell upper end outer rim is processed boss, and the upper shell internal cavity is for pressing the nut installing hole, and the upper shell profile is shaped on tapered slope.
And, the said leading screw that presses, its top is that thread segment is shaped on external screw thread, its underpart is shaped on external splines for the spline segment border.
And, said spline gear, wherein hole wall is shaped on internal spline.
Advantage of the present invention and beneficial effect are:
1. this three-roller type steel rolling mill pressuring upper device assembly has unit and assembly shell employing tapered slope location of one's own, and dismounting, installation, maintenance are conveniently;
2. this three-roller type steel rolling mill pressuring upper device assembly presses leading screw and spline gear and adopts spline to be connected drivings, and in conjunction with tight, driving force is strong, and the transmission moment of torsion is steadily reliable, heightens the positioning accuracy height;
3. each drive disk assembly of this three-roller type steel rolling mill pressuring upper device has the assembly shell protection, and good work environment is more durable in use.
4. this three-roller type steel rolling mill pressuring upper device assembly structure design science is reasonable; Have separate unit structure, dismounting, installation, maintenance convenient, rotate flexibly, driving force is strong, transmit moment of torsion steadily reliable, durable in use, heighten the positioning accuracy advantages of higher, be a kind of three-roller type steel rolling mill pressuring upper device assembly that has than high innovation character.

The specific embodiment
Through specific embodiment the present invention is made further detailed description below, following examples are descriptive, are not determinate, can not limit protection scope of the present invention with this.
A kind of three-roller type steel rolling mill pressuring upper device assembly; By assembly shell 4, housing bottom 7, press nut 3, press leading screw 2, high speed pinion 10, middle idle wheel 9,15, spline gear 6, brief biography moving axis 11 form; The housing bottom is packed in below the assembly shell and with the assembly shell bottom and constitutes gear-box 17 jointly; Press nut and be packed in the assembly shell internal upper part, press leading screw top and be rotatably installed in and press in the nut, the bottom is plugged in the spline gear; High speed pinion, middle idle wheel, spline gear all rotate to be installed in the gear-box and also are connected with a joggle successively, and brief biography moving axis bottom is rotatably installed on the gear-box and with the high speed pinion and installs mutually.
Assembly shell; Form 16 by upper shell 20, lower house; Upper shell, lower house branch are made as one up and down, and lower house internal cavity and housing bottom constitute gear-box, and upper shell upper end outer rim is processed boss 18; The upper shell internal cavity is for pressing nut installing hole 19, and the upper shell profile is shaped on tapered slope 5.
Press leading screw, its top is that thread segment is shaped on external screw thread, and its underpart is shaped on external splines 8 for the spline segment border.
Spline gear, wherein hole wall is shaped on internal spline.
Operation principle of the present invention is:
During assembling; Three-roller type steel rolling mill mainframe 13 bottom associated components are transformed; Make its become can with assembly shell boss and the tapered slope cavity shape of assembling closely; This three-roller type steel rolling mill pressuring upper device assembly is installed in the above-mentioned cavity, and the little power transmission shaft with this three-roller type steel rolling mill pressuring upper device assembly is connected with the big drive shaft 14 of main frame through shaft coupling 12 again, i.e. assembling finishes.When needs adjustment lower roll system height; Start the main frame hydraulic motor and drive the brief biography moving axis rotation that big drive shaft rotation and drive and big drive shaft link together; And then drive high speed pinion, middle idle wheel, spline gear, press leading screw and rotate; Press leading screw and in axial rotation, lean on screw thread in pressing nut, to do to rise or descending motion, thereby with lower roll system 1 jack-up or fall, realize the purpose of lower roll system height adjustment.When needing repairing, system unloads with lower roll, can change assembly at once, and also can when changing lower roll, change the pressuring upper device assembly in passing simultaneously and carry out maintaining, and the maintenance that needn't stop production for a long time.Particularly the assembly shell profile is taper, can be installed in the conical cavity of main frame bottom, and this pyramidal structure is pressed tighter and tighter when work, when dismounting, is easy to take out.
