Problems solved by technology

[0002] As the enhanced function of fin stabilizers on ship maneuverability and seakeeping is gradually recognized in China, fin stabilizers have been widely used in various ships; in recent years, with the continuous advancement and development of intelligent ships, unmanned boats Fin stabilizers are gradually being valued by the market. Different from ordinary small and medium-sized ships, small unmanned boats have small cabin space and small tonnage. Conventional fin stabilizers have relatively ample layout space and occupied tonnage in ordinary small and medium-sized ships. , but in small unmanned boats, conventional fin stabilizers cannot meet the space requirements; at the same time, conventional fin stabilizers usually use one drive with one fin, which requires more time for debugging and adjustment

Embodiment Construction

[0015] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0016] Such as figure 1 As shown, the unmanned boat fin stabilizer actuator of the present invention is mainly composed of a servo motor 1, a reducer 2, a bevel gear set 3, a potentiometer 4, a transmission shaft 5, a universal joint 6, a mounting seat 7 and a support seat 8 and so on. The servo motor 1 and the reducer 2 are connected by bolts, and the torque is transmitted by the key; the output shaft of the reducer 2 is connected with the bevel gear set 3, and the bevel gear set 3 is installed on the support base 8; the support base 8 is fixed on the unmanned boat by bolts Bottom plate; the bevel gear set 3 consists of three bevel gears arranged at a certain angle to form two pairs of rotating pairs, wherein the driving bevel gear is fixedly connected to the output shaft of the reducer 2, and the two driven bevel gears are meshed with the driving bev...

Abstract

The invention relates to an unmanned ship fin stabilizer executing mechanism based on bevel gear transmission. A servo motor is connected with a bevel gear set through a speed reducer, a driving bevel gear in the bevel gear set is fixedly connected with an output shaft of the speed reducer, two driven bevel gears are in meshed connection with the driving bevel gear, and the two driven bevel gears are respectively connected with an unmanned ship fin stabilizer through transmission shafts. Two pairs of bevel gears are introduced for transmission, so that the conversion of driving two fins by two servo motors to driving two fins by one servo motor is realized, the occupied space of a fin stabilizer executing mechanism is greatly reduced, and the requirement of an unmanned ship on small occupied space of a stabilizer is met; and the control of the fin stabilizer of the unmanned ship is changed from the original control of simultaneous reverse rotation of the two servo motors to the control of forward and reverse rotation of only one servo motor, so that the control program is greatly simplified, the equipment complexity is reduced, and the debugging time is shortened.
