を介して筒状支持フレーム４に偏心した位置で回転可能
に支持されている。In FIG. 1, reference numeral 1 denotes three rolling rolls radially arranged at 120 ° intervals in the vertical plane.
Are sandwiched between a pair of left and right roll holders 2, and each of these roll holders 2 has a bearing 3
It is rotatably supported at a position eccentric to the cylindrical support frame 4 via.
このように筒状支持フレーム４を介して各ロールホルダ

ことにより、各ロールホルダー２を圧延材料の中心に対
して移動させるため、すなわち圧延ロール１の圧下量を
調節するためである。In this way, each roll holder 2 is supported via the tubular support frame 4 because the roll holder 2 is moved with respect to the center of the rolled material by rotating the tubular support frame 4, that is, the rolling. This is for adjusting the amount of reduction of the roll 1.
なお、各圧延ロール１は、ロールホルダー２に連動連結
されたかさ歯車５を介して入力側歯車６により、回転駆
動されるように構成されている。Each rolling roll 1 is configured to be rotationally driven by an input side gear 6 via a bevel gear 5 interlockingly connected to a roll holder 2.
上記各圧延ロール１は、その両側面が左右のロールホル

付けられる。That is, as shown in FIG. 2, the pair of left and right roll holders 2 are configured so as to approach each other via the bolt 8 and the nut 9 which are tightening members. The annular groove portion 11 is formed, and the second annular groove portion 12 is also formed on each surface of the roll holder 2 corresponding to each of the first annular groove portions 11. Then, in each of these annular groove portions 11, 12, serration rings 13, 14 having serrations formed on one surface are respectively inserted, and further, of the serration rings 13, 14 inserted in the annular groove portions 11, 12 facing each other. The serrations are inserted so as to mesh with each other, and are attached to the rolling roll 1 and the roll holder 2 via mounting pins (not shown) or the like.
