FLOW CHANNEL OPENING/CLOSING DEVICE
To provide a flow channel opening/closing device capable of coping with changes in temperature of lubrication oil while suppressing complication of design.SOLUTION: A flow channel opening/closing device 10 comprises a driving source 11, control means 12 for controlling an operation of the driving source 11, and a power transmission mechanism 13 transmitting a rotational force of the driving source 11 to an external movable body G, and moves the movable body G to open/close a water channel. The driving source 11 comprises first and second motors 14 and 15 having different torque magnitudes. The power transmission mechanism 13 includes: a sun gear 21 into which the rotational force of the first motor 14 is input; an internal gear 22 into which the rotational force of the second motor 15 is input; and a planetary gear means 17 provided with a planetary carrier 23 outputting the rotational force toward the movable body G. The control means 12 switches between a first state in which the first motor 14 is operated and the second motor 15 is stopped and a second state in which the first motor 14 is stopped and the second motor 15 is operated, to adjust a magnitude of torque for raising and lowering the movable body G.SELECTED DRAWING: Figure 1
【課題】設計の複雑化を抑制して潤滑油の温度の変化に対応できる流路開閉装置を提供する。【解決手段】駆動源１１、駆動源１１の動作を制御する制御手段１２、及び、駆動源１１の回転力を外部の可動体Ｇに伝える動力伝達機構１３を備え、可動体Ｇを動かして水路を開閉する流路開閉装置１０において、駆動源１１は、トルクの大きさが異なる第１、第２のモータ１４、１５を具備し、動力伝達機構１３は、第１のモータ１４の回転力が入力される太陽歯車２１、第２のモータ１５の回転力が入力される内歯車２２、及び、可動体Ｇに向けて回転力を出力する遊星キャリア２３が設けられた遊星歯車手段１７を有し、制御手段１２は、第１のモータ１４を作動し第２のモータ１５を停止する第１の状態と、第１のモータ１４を停止し第２のモータ１５を作動する第２の状態とを切り替えて、可動体Ｇを昇降するトルクの大きさを調整する。【選択図】図１
