Abstract

PURPOSE:To obtain a large roll draft adjusting amount by supporting a rotation shaft to be freely rotatable by a rotating body and meshing a follower side gear with a driving side gear being concentrically and rotatively driven with the rotating body. CONSTITUTION:When a rotating body 4 is rotatively operated, a rotation shaft 3 supported by the body 4 is shifted in a radial direction to perform position adjustment of a rolling roll 2 because the shaft 3 and the rotation center of the body 4 are separated in parallel to each other. The rotation center of a driving side gear 17 is concentric with the rotation center of the body 4 and a follower side gear 16 is concentric with the rotation shaft 3. A parallel and separated distance between the center of the body 4 and the shaft 3 does not change with rotation of the body 4. Hence, a center-to-center distance of the gears 17 and 16 does not change and meshing condition of both the gears 16, 17 is maintained in a constant proper condition at all times even if the body 4 is rotated and radial position adjustment of the rolling roll 2 is performed.

９号公報に開示されている。(Prior art) In a three-way rolling roll stand, each rolling roll is driven to rotate and needs to be moved in the radial direction to adjust the amount of rolling reduction, so the rotating shaft of the rolling roll is interlocked and connected to a drive source. , it is necessary to be able to move and position freely in the radial direction. This kind of three-way rolling roll stand was developed in 1976-346.
It is disclosed in Publication No. 9.

In addition, the rotating shaft 3' is supported via an eccentric bearing (not shown) whose rotation can be freely adjusted, so that it can be freely moved and positioned in the radial direction. When the rotating shafts are interlocked, if the bevel gear 30' is fixed to the rotating shaft 3'', the meshing state of the bevel gears will become inappropriate if the radial position of the rotating shaft 3'' changes. Put it away. Therefore, each bevel gear 30' is assumed to move in the axial direction via a screw mechanism (not shown) as the rotation axis moves in the radial direction by 3 degrees, and the bevel gear 30' is moved in the axial direction through a screw mechanism (not shown).
It is assumed that the meshing state of the two can be maintained.

ものとされている。The above publication also discloses a structure shown in FIG. 6. That is, a bevel gear 30' is provided and meshed with the rotating shaft 3' of each rolling roll 2', and one rotating shaft 3' is connected to the drive source M. Furthermore, the rotating shaft 3'' is supported via an eccentric bearing (not shown) whose rotation can be freely adjusted, so that it can be moved and positioned in the radial direction.The inner circumference of each bevel gear 30'' is equipped with a sun internal gear 31° is formed and meshes with the planetary gear 32° on the outer circumference of the rotating shaft 3°, so that even if the rotating shaft 3'' moves in the radial direction, the planetary gear 32° will not revolve around the sun internal gear 31°. by doing,
Each bevel gear 30' does not need to move in the radial direction, and a proper meshing state of the bevel gear 30' can be maintained.

は傘歯車３０゛　の軸方向の移動量の１７ｆ３となる。(Problem to be Solved by the Invention) As in the past, when the bevel gear 30' is moved in the axial direction with the radial movement of the rotating shaft 3'', it is difficult to arrange the three rolling rolls at equal intervals in the circumferential direction. Since the conical angle of the tip of the bevel gear 30' is 60 degrees, the amount of radial movement of the rotating shaft 3 degrees is 17f3, which is the amount of axial movement of the bevel gear 30'.

量が僅かなものとなるという問題がある。Furthermore, the amount of axial movement of the bevel gear 30' is limited by an eccentric bearing or the like between the roll 2' and the bevel gear 30'. Therefore, there is a problem that the amount of radial movement of the rotating shaft 3'' cannot be made very large, and the amount of adjustment of the rolling reduction amount of the roll 2'' becomes small.

かなものとなるという問題がある。In addition, when using the conventional structure in which a solar gear 31'' is formed on the inner periphery of the bevel gear 30° and a planetary gear 32'' is formed on the rotating shaft, the amount of radial movement of the rotating shaft 3'' is Internal gear 3
It is determined by the difference in pitch diameter between 1゛ and the planetary gear 32゛. However, since the sun internal gear 31' is located on the circumference of the bevel gear 30', its diameter is limited, and the planetary gear 32' also needs to have at least approximately the same diameter as the rotation axis 3° from the viewpoint of strength etc. , the difference in the diameter of Pino 1,000 yen cannot be very large. Therefore, there is a problem that the amount of adjustment of the rolling reduction of the roll 2° is small.
