Description

Technical Field

[0001] This invention relates to a marine propulsion system, and more particularly to a steering mechanism for an azimuth thruster. Background Technology

[0002] With the in-depth development of ship electric propulsion systems, azimuth thrusters have become the mainstream electric propulsion device and are widely used. An azimuth thruster consists of a steering mechanism and an underwater structure; the former enables heading control, while the latter enables propulsion. Currently, the most common steering mechanisms are hydraulic motor steering mechanisms, electric motor steering mechanisms, and worm gear steering mechanisms. The hydraulic motor steering mechanism consists of a hydraulic pump station, a hydraulic motor, a gearbox, and gear pairs; the electric motor steering mechanism consists of a rotary motor, a gearbox, and gear pairs; and the worm gear steering mechanism consists of a hydraulic motor or electric motor, a turbine, and a worm. All three types of steering mechanisms use a drive source as the power input and a transmission mechanism as a speed-reducing and torque-increasing device to achieve the steering function.

[0003] Clearly, all three types of steering mechanisms occupy a significant amount of cabin space, sacrifice some mechanical transmission efficiency, and inevitably generate mechanical vibrations. To improve the utilization of cabin space and enhance ship comfort, it is necessary to innovate the design of the steering mechanism. Summary of the Invention

[0004] The purpose of this invention is to propose an integrated motor-type steering mechanism for a full-rotation propeller, which integrates the power drive source and the slewing bearing into one unit, eliminating the need for a hydraulic motor or electric motor and gearbox transmission device, and achieving a compact, environmentally friendly, and low-noise design for the steering mechanism.

[0005] To achieve the above objectives, the technical solution of the present invention is: an integrated motor-type rudder mechanism for a full-rotation propeller, comprising an integrated motor, a hull connecting plate, a slewing bearing, and a locking mechanism. The integrated motor and the slewing bearing are integrated into one unit, wherein the stator of the integrated motor is connected to the stator of the slewing bearing, and the rotor of the integrated motor is connected to the rotor of the slewing bearing. When the rotor of the integrated motor rotates under electromagnetic force, it directly drives the rotor of the slewing bearing to rotate together, thereby realizing rudder turning.

[0006] Furthermore, the integrated motor stator is mounted on the hull connecting plate, which is connected to the hull base, transmitting the steering torque and propulsion force to the hull.

[0007] Furthermore, an external gear ring is installed on the outer ring of the integrated motor rotor, and the external gear ring meshes with a pinion, which is installed on the hull connecting plate.

[0008] Furthermore, the pinion is equipped with a disc brake.

[0009] Furthermore, when not steering, the disc brake device engages to apply the brakes and fix the steering mechanism.

[0010] Furthermore, when turning the rudder, the disc brake device automatically opens, allowing the integrated motor rotor to rotate freely.

[0011] The beneficial effects of this invention are:

[0012] The present invention discloses an integrated motor-type steering mechanism for a full-rotation propulsion system, which integrates an integrated motor (also known as a flange-type motor) and a slewing bearing into one unit. The stator of the integrated motor is connected to the stator of the slewing bearing, and the rotor of the integrated motor is connected to the rotor of the slewing bearing. When the rotor of the integrated motor rotates under electromagnetic force, it directly drives the rotor of the slewing bearing to rotate together. The underwater structure of the full-rotation propulsion system rotates together with the rotor of the slewing bearing, thereby realizing steering, and there is no intermediate mechanical transmission link.

[0013] This invention discloses an integrated motor-type steering mechanism for a full-rotation propeller. The mechanism includes a steering locking mechanism where an external gear ring is mounted on the outer ring of the integrated motor rotor and meshes with a pinion. The pinion is mounted on a hull connecting plate and is equipped with a disc brake. When not steering, the disc brake engages to lock the steering mechanism; when steering, the disc brake automatically disengages, allowing the integrated motor rotor to rotate freely.

[0014] The integrated motor-driven steering mechanism of the azimuth thruster of this invention integrates the power drive source and the slewing bearing into one unit, directly driving the underwater structure to achieve steering by the integrated motor, reducing intermediate transmission links.

[0015] Improve transmission efficiency, reduce mechanical vibration, and save cabin space. Attached Figure Description

[0018] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0019] like Figure 1As shown in Figure 2, the present invention discloses an integrated motor-type steering mechanism for an azimuth thruster, which is applied in an azimuth thruster to realize the steering function. The azimuth thruster is divided into a steering module 1 and an underwater structure 2. The steering mechanism, as a key component of the steering module, includes a slewing bearing stator 11, a slewing bearing rotor 12, an integrated motor connecting flange 13, an integrated motor stator 14, an integrated motor rotor 15, an integrated motor rotor external gear ring 16, a disc brake device 17, a locking pinion 18, and a hull connecting plate 19, etc.

[0020] The integrated motor (also known as a flange-type motor), including the integrated motor connecting flange 13, integrated motor stator 14, integrated motor rotor 15, and integrated motor rotor external gear ring 16, is integrated with the slewing bearing stator 11 and slewing bearing rotor 12. The integrated motor stator 14 is connected to the slewing bearing stator 11, and the integrated motor rotor 15 is connected to the slewing bearing rotor 12. When the integrated motor rotor 15 rotates under electromagnetic force, it directly drives the slewing bearing rotor 12 to rotate as well. At this time, the underwater structure 2 of the azimuth thruster rotates together with the slewing bearing rotor 12, thus achieving rudder control.

[0021] Preferably, the integrated motor stator 14 is mounted on the hull connecting plate 19 via the connecting flange 13. The hull connecting plate 19 is connected to the hull base flange 20, which transmits the steering torque and propulsion force to the hull.

[0022] Additionally, the steering mechanism consists of an external gear ring 16 and a locking pinion 18. The external gear ring 16 of the integrated motor rotor 15 is mounted on the outer ring of the integrated motor rotor 15 and meshes with the locking pinion 18. The locking pinion 18 is installed in the bearing housing of the hull connecting plate and has a disc brake device 17. When not steering, the disc brake device 17 applies the brake to fix the steering mechanism and maintain the course; when steering, the disc brake device 18 automatically opens, allowing the integrated motor rotor 15 and the slewing bearing rotor 12 to rotate freely.
