Definitions
- the invention relates to a drive device for a rolling device, comprising at least one drive motor, a main gear, a pinion gear, a rolling stand with work rolls and connecting these components clutches, spindles and the like, wherein in the main transmission, a drive axle and an output shaft have a horizontal distance.
- Drive motors, main gearbox, pinion gear and rolling stands are constructed and mounted on a common or several individual foundations.
- the design and layout of the foundations depends i.a. from the weights of the components mentioned as well as the moments to be transmitted.
- a rolling mill with the main components such as motors, gearboxes, rolling mills, rolls etc. is from the Technical Report Hot Strip and Strip Production "Rolling mill expansion at Alcan Aluminio do Brasil", special edition from Light Metal Age 1999, no. 6, p 8-13 and Metallurgical Plant Technology VoI 22 (1999) no. 6, p. 38-44, authors: R.M. Rocha, K.A. Gdovka and ST. Kerbaugh known.
- DE 199 11 751 C1 describes a drive device for a roll stand with two work rolls, wherein the drive device has a gear with two toothed rollers, one of which can be coupled to one each with a work roll of the rolling stand.
- the toothed rollers have a different number of teeth.
- Drive devices for rolling devices consisting of at least one motor and one transmission are furthermore known from DE 699 121, DE 924 983, DE 44 08 289 A1 and DE 694 11 580 T2.
- the known rolling devices are designed for a specific type (hot rolling / cold rolling) and for predetermined properties of the rolling stock.
- the existing facilities can only be charged or used up to a limit set a long time ago.
- the invention is therefore based on the object to improve a drive device of the type described above such that the above-mentioned disadvantages / problems are avoided.
- This object is achieved in that the drive axle in the main gear single stage and the drive axle is formed with an upward, vertical distance to the output shaft.
- the horizontal distance between the axes remains the same, but the spatial distance can be increased to take into account, for example, larger axle diameter, larger gear diameter, etc.
- the main transmission is multi-stage, i. formed at least two stages.
- three- or four-stage versions are possible.
- the design of the main gear is such that the horizontal center distance remains identical.
- a vertical displacement of the drive shaft upwards is possible because a displacement of the drive motor on the existing and unchangeable foundation in the vertical direction can be done by an intermediate frame in a simple manner.
- the advantage of the drive device according to the invention is that the production quantities can be increased, the quality of the rolling stock improved, lower final thicknesses produced and new products (steel grades) can be produced.
- the motors used in the existing rolling apparatus can continue to be used.
- new engines can also be used.
- FIG. 1 shows a top view of the individual components of a rolling device
- FIG. 4 shows a front view of a multi-stage main transmission according to the invention
- Figure 5 in a sectional plan view of a two-stage main transmission
- Fig. 1 the components of a rolling device W are shown in plan view. From a motor M, a torque is transmitted to a main transmission HG. This is connected for example by means of an intermediate pipe coupling ZRK with a pinion gearbox KWG. From there, the work rolls AW are driven by a rolling stand G via toothed spindle ZS.
- the other rolling stands G which are placed at a distance g from the first stand G drive.
- the distance g between a plurality of rolling stands G and the distance I between a plurality of drive devices may be the same or different.
- a known main gear HG has a drive shaft and an output shaft which are connected by means of an existing gear pair.
- the main transmission HG is arranged on a foundation F.
- Figures 4 and 5 A development of the embodiment according to the invention can be seen in Figures 4 and 5.
- the drive axis AN and the output axis AB of the main transmission HG are connected to each other via a two-stage gear pair or transmit torque.
- the invention is shown in FIG.
- the drive axis AN and the output axis AB of a rolling device W have both a horizontal distance hA and a vertical distance vA.
- the axis of the drive motor Based on an existing foundation, which can not be structurally altered due to time constraints, the axis of the drive motor only has to be adapted in the vertical direction.
