Patent number: 10232432Abstract: A mold oscillator includes: a ball screw unit that has a ball screw 32having a threaded shaft 29 and a ball nut 30, and a nut-side shaft 31 fixed to the ball nut 30 coaxially with the threaded shaft 29, wherein the ball screw unit is positioned so that the central axis of the ball screw unit extends in the vertical direction; and a power transmitting mechanism that transmits rotation to the ball screw unit. Bearings rotatably support a first shaft. A second shaft that is the other of the threaded shaft and the nut-side shaft is connected to the mold side. An attachment portion to fix the mold oscillator at an installation position is provided so as to be immovable relative to the bearings in the vertical direction and is configured to be able to change the relative position between the bearings and the second shall in the vertical direction in a state where operation of the mold oscillator is stopped.Type: GrantFiled: February 9, 2016Date of Patent: March 19, 2019Assignee: JP STEEL PLANTECH CO.Inventor: Yuki Kadowaki

Patent number: 10189078Abstract: A mold oscillator includes a ball screw unit that has a ball screw 32 having a threaded shaft 29 and a ball nut 30, and has a nut-side shaft 31 fixed to the ball nut 30 coaxially with the threaded shaft 29, wherein the ball screw unit is positioned so that the central axis of the ball screw unit extends in the vertical direction. A casing surrounds at least part of the ball screw 32. The ball nut 30 of the ball screw 32 and part of the threaded shaft 29 of the ball screw 32, on which, part the ball nut 30 is engaged with the threaded shaft 29, are submerged in a lubricating oil so as to be able to lubricate the ball screw 32 with an oil bath.Type: GrantFiled: February 9, 2016Date of Patent: January 29, 2019Assignee: JP STEEL PLANTECH CO.Inventor: Yuki Kadowaki

Patent number: 9387641Abstract: A solid-liquid separation device includes a plurality of fixed members and movable members that are movably disposed between the adjacent fixed members, and a screw extending through the fixed members and the movable members in a state where the screw is not in contact with the fixed members and the movable members. The screw is rotationally driven about a center axis line thereof. A filtrate separated from an object is discharged to the outside of the solid-liquid separation portion through filtrate discharge gaps, and the object that has a reduced liquid content ratio is discharged from the outlet to the outside. In order to increase significantly a dewatering ratio, the movable members are formed to move while penetrating closer to the center axis line of the screw than an outer circumferential edge of the blade of the screw, without coming into contact with the screw.Type: GrantFiled: January 17, 2012Date of Patent: July 12, 2016Assignees: AMUKON KABUSHIKI KAISHA, AMCON NA, INC.Inventors: Kazuo Kaneko, Yusuke Tezuka, Yoshitaka Nakamura, Yuki Kadowaki, Hirokazu Kobayashi
