The utility model solves its technical problem and realizes through following technical scheme:
A kind of three-roller type steel rolling mill pressuring upper device; 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 utility model and beneficial effect are:
1. this three-roller type steel rolling mill pressuring upper device 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 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 scientific structure design 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 that has than high innovation character.

The specific embodiment
Through specific embodiment the utility model is done further to detail below, following examples are descriptive, are not determinate, can not limit the protection domain of the utility model with this.
A kind of three-roller type steel rolling mill pressuring upper device; By assembly shell 4, housing bottom 7, press nut 3, press leading screw 2, high speed pinion 10, middle idle wheel 9, middle idle wheel 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.
