Abstract

PURPOSE:To remarkably improve an accuracy of roll stopping, by installing a reducer, having a driving motor used for an independent operation, between a motor used for rolling and a driving part of a main body of rolling mill. CONSTITUTION:In a planetary type skew rolling mill, a reducer 18, having a driving motor used for an independent operation, is installed between a motor 13 used for rolling and a driving shaft 14 of the rolling mill locating at the mill side. One side of an output shaft 19 of the reducer 18 is connected to the motor 13 through a detachable clutch 20 and the other side is connected to the driving shaft 14 locating at the mill side through a coupling 21. At the same time, in the reducer 18, a gear 25 fixed to the output shaft 19 is meshed with an idle gear 24 which is supported in a freely rotatable state by a bearing 23 on an idle gear shaft 22. A clutch half 30, made to mesh with a clutch half 28, is provided to the idle gear 24 to interlock the idle gear 22 with the driving motor 17 used for operation so that the clutch half 28 supported by the shaft 22 transmits the driving torque.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention provides a driving device 1061 for a sloping roller.
Figure 1 is a typical example of this type of inclined roll rolling mill. An overview of one example is shown below. A roll head (4) supporting a roll shaft (easy) to which eight conical rolls (!) are attached around the rolled material (1) passing through its center in an inclined axis arrangement is fitted into a rotor (6), The rotor (s) is supported by a projection stand (・)K and is rotationally driven by a main drive system (described later) via a bevel gear (7) (75).The rotor (s) is also rotatably driven by a bevel gear (7) (75) by an auxiliary drive system (described later). The sun gear (9), which is rotationally driven through the eight planetary gears that mesh with the sun gear (9), is connected to the roll shaft through the bevel gear ha) ($)
The rotation drive is tight. The rolling operation is carried out by these drives 11JK. In the prior art drive device of this type of rolling mill, as shown in Figure 2, the rolling drive section (b) is connected to the main drive shaft (b) that produces the rolling. and roll (meaning) t) Roll (
It has a gore part driving shaft (to) that transmits the rotation from the upper motor 2) for K rolling operation. However, the words "main motor (2)" and "auxiliary motor (to)" are not directly coined with the respective drive shafts.

Supplement I When exchanging rolls or rolling heads, the rotor (i) is connected to the main motor Ql for rolling operation.
Therefore, it is necessary to stop it at a predetermined position with high precision. On the other hand, when adjusting the reduction amount of the roll (!) to change the exit diameter, the reduction device is controlled by the rolling operation 1llIIaIl14-Even (To) in the pigeon coop where the roll is adjusted to a constant position for replacing the roller. stone. These operations, control 1
The main motor (to) and the auxiliary motor (to) can be calculated at the rated rotation speed (D 1/16 to 1/80 Vf) @ rotation speed of the main motor (to). However, the drive of the prior art described above The device uses a large-capacity rolling motor (2) (2) with a rated rotation speed of 171 for rounding for W-roll stop control or for rolling reduction adjustment of rolls.
6~1/801i degree low rotation 1 is used for J+ rounding electric power which is difficult to control with 4b force, # control.

Adjustment accuracy is low. In addition, the main drive system is regulated by the main reduction ratio of the rolling mill main body.*It is necessary to control the extremely large moment of inertia of the mechanical system, and also to control the relatively large moment of inertia of the rolling IIIPI motor itself. These make control even more difficult. In particular, the design strength of the rolling T device is much smaller than the rated torque of the auxiliary gear for rolling operation. This increases the difficulty of control.

In order to solve the above-mentioned problem of the driving device of the advance clamping method, the present invention is designed to solve the above-mentioned problem of the driving device of the advance clamping method, and the driving device for the rolling operation is provided with an independent driving section between the rolling operation shaft and the rolling mill main body driving section. The rotor is stopped separately from the drive system during rolling.The drive system of the operation drive motor is used for the adjustment work to adjust the roll reduction. - The output shaft has sufficient strength to be able to transmit the relatively large transmission torque of the rolling operating motor, and the other part of the reduction is made large enough to accommodate the relatively small torque transmission of the operating drive motor. Make the rim smaller.

The present invention will be explained in detail below with reference to embodiments shown in FIGS. 8 and 4. FIG. 3 shows a plan view of the drive device according to the present invention for food fishing.

FIG. 4 is a diagram illustrating the drive system of the drive device according to the present invention, with the side related to the main motor for rolling operation taken as a representative example. The side related to Rolling Work 11M1 Supplementary Tanabata also has essentially the same configuration.

In particular, in the drive system of the planetary 1 inclined roll rolling ridge shown in No. 411, the amount of soil for rolling operation (2) and the rolling 11111
On the main drive shaft 1 and 0111, there is arranged an independent drive motor A, that is, an unshielded scale connected to the rotor control cage. The output shaft of the M*04 is connected on one side to the main motor for rolling operation (2) via a latch so that it can be turned on and off, and on the other hand is connected to the main drive motor on the rolling mill side via a super IIO shaft driver. Shaft (b) Seven can be easily connected. The output shaft has a particularly large shaft diameter to accommodate the relatively high transmission torque of this drive system.

In the QIK model, the idle gear shaft is installed parallel to the output shaft (2), and the idle gear is rotatably supported by a bearing on the idle gear shaft ring. )K

The torque is transmitted to the main drive shaft 04K via the idle gear shaft (1), the clutch 11, the idle gear (2), and the gear (2), thereby controlling the rotation of the rotor (6) to stop the same rotation.

With the newly installed nine reduction we (to), an arbitrary loading ratio can be obtained regardless of the design of the planetary inclined roll rolling unit, so the repetition drive motor can be used at a rotation speed higher than the rated speed.) Highly accurate II fishing control becomes possible.
