Title:
WATER GATE OPENING AND CLOSING DEVICE
Document Type and Number:
Japanese Patent JP3726200
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To enable opening and closing fine adjustment for a water gate.
SOLUTION: This device includes an auxiliary motor rotation transmitting gear 17 journalled to an output shaft 14 in such a manner as to mesh with a differential gear 16 journalled to a differential gear shaft 15 fixed in such a manner as to intersect perpendicularly to the output shaft 14, and a main input gear 18 fixed to the shaft 19 of a main motor 4. An auxiliary input gear 20 fixed to the shaft 21 of the auxiliary motor 4 is meshed with the auxiliary motor rotation transmitting gear 17, the diameter of the auxiliary motor rotation transmitting gear 17 is made larger than the diameter of the auxiliary input gear 20 to decelerate, and the main motor 2 and the auxiliary motor 4 are provided with a brake mechanism. According to the principle of the differential gear 6, by the combination of a mechanism for making the rotating directions of the main motor 2 and the auxiliary motor 4 the same or reverse to revolve the differential gear 16 and a mechanism for driving only the main motor 2 or the auxiliary motor 4 to revolve the differential gear 16 by the brake mechanism, four kinds of output is enabled to control the opening and closing speed of a water gate in four stages.
