Summary:PURPOSE: To provide a rolling mill of which the rolling mill and devices around a driving reduction gear connected to the mill can be made compact and angularity on the inside surface of a pipe after rolling is prevented. CONSTITUTION: This device consists of plural rolls 1 symmetically arranged around the pass line, a driving bevel gear 4 having a ring shaped large diameter for rotationally driving the rolls 1, an input shaft mechanism 5 for rotating the driving bevel gear 4, plural gear transmission mechanisms 8 arranged at equal intervals in the peripheral direction of the bevel gear 4 and a housing 3 for holding them. The input shaft mechanism 5 consists of one input shaft 6 which penetrates the housing 3 from the outside to the inside, a small diameter input bevel gear 7 which is fixed to the input shaft 6 and engaged with driving bevel gear 4 and the input shaft mechanism 5 is arranged between a pair of gear transmission mechanisms 8, 8 which are adjacent to each other in the peripheral direction. Even when the input shaft 6 is horizontally arranged, the phase angle of the roll is finely variable. 압연기(壓延機)나 이에 접속되는 구동용 감속기 주위를 컴팩트화할 수 있으며, 압연후의 파이프 내면에 모가 나는 것을 방지할 수 있는 롤 압연기를 제공한다. 패스라인(path line)을 중심으로 하여 대칭으로 배치된 여러 개의 롤(1)과, 롤(1)을 회전구동시키는 직경이 큰(大徑) 링 형상의 구동용 베벨기어(4)와, 구동용 베벨기어(4)를 회전시키는 입력축기구(5)와, 구동용 베벨기어(4)의 원주방향에 등(等) 간격으로 배치된 여러 개의 전달기구(8)와, 이들을 지지하는 외측 하우징(3)으로 이루어지고, 입력축기구(5)가 외측 하우징(3)의 외부에서 내부로 통하는 1개의 입력축(6)과 입력축(6)에 부착되어 구동용 베벨기어(4)에 맞물린 직경이 작은(小徑) 입력용 베벨기어(7)로 이루어지고, 입력축기구(5)는 원주방향으로 인접하는 1쌍의 전달기구(8, 8) 사이에 배치되어 있다. 입력축(6)을 수평으로 배치해도 롤의 위상각(位相角; phase angle)을 세세하게 변경할 수 있다.
