Description

one

The invention relates to the field of metal processing by pressure, in particular, to the design of .H-pHiBOfla rolling mills.

The rolling mill shank is known, consisting of an engine and gear reducers, located 1 on the opposite sides of the working stand relative to the rolling axis, / and gearboxes having output shafts, preferably hollow, connected to soy, diyelnye couplings with working shaft arms, are hingedly suspended from the working cell and it is likewise / fixed in working position. However, the well-known drive characterizes the lack of convenience in the maintenance of other handling.

The proposed roll of pro-katnoro stadi is characterized in that for convenience of servicing the axis of the hinged suspension of the gearboxes are perpendicular to the working plane.

FIG. 1 shows a rolling mill; “And FIG. 2 is a front view along arrow A. In FIG. one; in fig. 3 - view along arrow B. On FIG. 2; in fig. 4 is a cross-section. In bb, in FIG. 1 (along a gear (reducer); in Fig. 5, a section along G-D in Fig. 1 (; along the stand of the working stand of the mill).

The rolling mill includes a working stand 1 with pivotally suspended; 2 and 3 gears located on opposite sides of the working stand 1 with respect to the rolling axis, and the axles of suspension of the gearboxes 2 and 3 are fingers 4 which are perpendicular to

plane norkatki. Gearboxes 2 and 3 are connected to the electric motor 5 of the main drive through gears 6, mixed in planes, (Made in / around the bed of the working stand 1. TaKfHM, electric motor 5 through sleeve-finger couplings 7,

gears 6 and slotted coupling 8

It is engaged with the shafts 9 of the first gear stage.

Shafts 10 output gears 2 and

3 1 hollow cores. Through the holes in

The shafts of couplings II, equipped with universal joints 12. The couplings 11 are connected via universal joints toothed gearboxes 2 and 3 with the work rolls 13 and 14 installed in the pillows 15 and 16. The bore sizes of the shafts 10 exceed the maximum lateral dimension of the corresponding work roll 13 or 14 assembled with a cushion 15 or 16. In the working position, the gearbox 2 and 3 are fixed to the bolts and relative to the working stand.

Pillows 17 of the support rolls 18 are also placed on the working stand 1, and the pillows of the upper support roll are connected with pressing screws 19 of the mechanism for adjusting 20 of the working roll solution.

The main drive of the rolling mill rolls operates as follows.

Through the sleeve-pin couplings 7, gears 6 and hl tseed sleeves 8, the torque from the electric motor 5 is transmitted to the shafts 9 of the first stage of gearboxes 2 and 3. The shafts 10. Of the last output stage of these gearboxes are connected by couplings 11, equipped with UNI-1salvnymi hinges 12, with work rolls 13 and 14.

 handling of the work rolls of the gearbox 2 and 3, the axle articulated axes lined up in the form of fingers 4 are folded out (the gearboxes are folded up (shown by the fixed point in Fig. 1 and 3). In this case, the splined couplings 8 are disconnected from the shafts 9 and the universal joints 12 from the ends of the working.-shafts 13 and 14, i.e., the coupling 11, located inside the hollow shafts 10, rotate together with the gearboxes, and 2 and 3. After that, however, it is easy to access the ends of the work rolls.

F o r iM inla

First rolls of npOKaTiHoro mill consisting of an engine / and gear reducers,

located on the opposite-working sides of the rolling board with respect to the rolling axis, 1dricham gearboxes with output shafts, preferably hollow, connected by coupling couplings with working rolls,

are hinged to the working stand and are equipped with locking mechanisms in the working position, characterized in that, for ease of maintenance, transferring the axis of the shaft of the gearboxes are perpendicular to the rolling plane. .
