Problems solved by technology

However, the existing full-turn rudder mechanism realizes full-turn through hydraulic pumps, hydraulic motors and driving devices. Not only the structure is complex, but also a lot of power loss will be generated during the transmission process, and the stability of the rudder is poor, resulting in the rotation of the propeller. not smooth

Embodiment

[0019] See attached Figure 1-3 As shown, a new full-turn rudder mechanism of the rim-type electric propulsion device of the present invention includes a base 1, and the base 1 is provided with a rotating part driven by a power assembly to rotate, and the rotating part The upper end of the adapter plate 3 is connected with the slewing support 2, and the lower end is connected with the transmission shaft 4. The transmission shaft 4 The lower end extends out of the base 1 and is connected with the propeller. The power assembly includes a pair of geared motors 5 fixed on the base 1, the output shaft of each of the geared motors 5 is connected with a gear 6 meshing with the outer ring of the slewing bearing 2, and A pair of said gears 6 are arranged symmetrically on both sides of said slewing bearing 2 .

[0020] The reduction motor 5 drives the gear 6 to rotate, and then drives the slewing bearing 2 to rotate 360°, and then transmits the rotation of the slewing bearing 2 to the...

Abstract

The invention discloses a novel full-rotation steering mechanism of a rim type electric propeller, the novel full-rotation steering mechanism comprises a base, a rotating part capable of rotating under the driving of a power assembly is arranged in the base, the rotating part comprises a slewing bearing, a switching disc and a transmission shaft which are coaxially arranged, the upper end of the switching disc is connected with the slewing bearing, the lower end is connected with the transmission shaft, and the lower end of the transmission shaft extends out of the base and is connected with a propeller. The power assembly comprises a pair of gear motors fixedly connected to the base, the output shaft of each gear motor is connected with a gear meshed with the outer ring of the slewing bearing, and the pair of gears are symmetrically arranged on the two sides of the slewing bearing. The full-rotation steering mechanism is simple in structure, space is saved, power loss is reduced, and steering stability is improved.

Description

technical field [0001] The invention relates to the technical field of ship propulsion, in particular to a novel full-turn rudder mechanism of a rim-type electric propulsion. Background technique [0002] Ship propeller refers to the energy converter in the ship propulsion device, which converts the power generated by the engine into the thrust of the ship to overcome the resistance of the ship navigating in the water and push the ship forward. The most common is the propeller. As the power source of the ship propeller, the full-turn rudder mechanism is mainly used to control the rotation of the propeller. However, the existing full-turn rudder mechanism realizes full-turn through hydraulic pumps, hydraulic motors and driving devices. Not only the structure is complex, but also a lot of power loss will be generated during the transmission process, and the stability of the rudder is poor, resulting in the rotation of the propeller. Not smooth. Contents of the invention ...
