Description

Technical Field

[0001] The present invention relates to the technical field of ships and ocean engineering, and in particular to a dual-gyro anti-roll device. Background Art

[0002] When ships are sailing or operating at sea, they are subject to environmental disturbances such as wind, waves, and currents, generating complex six-degree-of-freedom motions. Roll, in particular, has the most significant impact on a ship's safety, habitability, and operational efficiency. Therefore, effectively suppressing roll has always been a key issue in shipbuilding. Existing roll stabilization devices include fin stabilizers, bilge keels, water tanks, gyros, and rudder stabilizers. However, these mainstream roll stabilization technologies are complex, require significant space, and are heavy. Summary of the Invention

[0003] The purpose of the present invention is to solve the problems raised in the above background technology and provide a dual gyro anti-roll device.

[0004] To achieve the above object, the technical solution of the present invention is: A dual-gyro anti-roll device includes a frame, a transmission mechanism mounted on the frame, a driving member, and two gyro rotors. One of the two gyro rotors is provided with a first rotor shaft, and the other is provided with a second rotor shaft. The first rotor shaft and the second rotor shaft are respectively rotatably connected to the frame. The transmission mechanism is respectively in transmission connection with the first rotor shaft, the second rotor shaft, and the output shaft of the driving member, so that the two gyro rotors rotate in opposite directions at the same speed under the drive of the driving member.

[0005] It can be understood that the driving member serves as a power source, driving the two gyro rotors to rotate in opposite directions at the same speed at the same time. That is, the two gyro rotors are driven by the same driving member, ensuring that the speeds of the two gyro rotors are strictly consistent. In this way, there is no need to install a corresponding driving member on each gyro rotor, thereby reducing the number of driving members and improving space utilization.

[0006] In one embodiment, the transmission mechanism includes a first synchronous wheel, a second synchronous wheel, a third synchronous wheel and a transmission belt, the first synchronous wheel is connected to the output shaft, the second synchronous wheel is in transmission connection with the second rotor shaft, and the third synchronous wheel is connected to the first rotor shaft. The transmission belt is respectively engaged with the first synchronous wheel, the second synchronous wheel and the third synchronous wheel, so that the first synchronous wheel drives the second synchronous wheel and the third synchronous wheel to rotate simultaneously under the drive of the output shaft.

[0007] It is understandable that, through the reasonable arrangement of the first synchronous wheel, the second synchronous wheel, the third synchronous wheel and the transmission belt, the transmission mechanism can simultaneously drive the first rotor shaft and the second rotor shaft to rotate, thereby making the two gyro rotors rotate in opposite directions at the same speed.

[0008] In one embodiment, the transmission mechanism further includes a first gear, a second gear and a transition shaft, the first gear is engaged with the second gear, the first gear is connected to the second rotor shaft, the second gear is connected to one end of the transition shaft, the second synchronous gear is connected to the other end of the transition shaft, and the transition shaft drives the second rotor shaft to rotate through the first gear and the second gear.

[0009] It can be understood that, through the reasonable arrangement of the first gear, the second gear and the transition shaft, the transmission connection between the second synchronous gear and the second rotor shaft is achieved, and the rotation directions of the second rotor shaft and the first rotor shaft are opposite.

[0010] In one embodiment, the first rotor shaft is configured to rotate forward, and the second rotor shaft is configured to rotate counterclockwise.

[0011] In one embodiment, the axis of the first rotor shaft is arranged parallel to the axis of the second rotor shaft.

[0012] It is understandable that the lateral moment generated by the precession of a single gyroscope may cause the pitch of the ship to intensify, and the parallel setting can partially offset the hull roll coupling effect caused by the precession of the single gyroscope.

[0013] In one embodiment, the first rotor shaft and the second rotor shaft are both welded and fixed to the corresponding gyro rotor.

[0014] It is understandable that the connection is more secure when fixed by welding.

[0015] In one embodiment, the gyro rotor includes a housing, a rotor body, and a rotor motor. The rotor body and the rotor motor are installed inside the housing, and the rotor motor can drive the rotor body to rotate.

[0016] In one embodiment, the shell includes a shell body, a shell upper cover and a shell lower cover, the shell upper cover and the shell lower cover are respectively covered on both sides of the shell body, and the rotor body is rotatably connected to the shell upper cover and the shell lower cover through bearings.

[0017] In one embodiment, the frame further includes a first side plate, a second side plate and a support frame, the first side plate and the second side plate are connected by a connecting column, the support frame is mounted on the second side plate, the two gyro rotors are located between the first side plate and the second side plate, and one end of the first rotor shaft is rotatably connected to the first side plate, and the other end of the first rotor shaft is rotatably connected to the support frame.

[0018] In one embodiment, the driving member is configured as a servo motor.

[0019] Effects of the present invention: The present invention seeks to protect a dual-gyro anti-roll device in which two gyro rotors are driven by the same drive element, ensuring that the rotational speeds of the two gyro rotors are strictly consistent. This eliminates the need to install a corresponding drive element on each gyro rotor, thereby reducing the number of drive elements and improving space utilization. This effectively overcomes the complexity, space, weight, efficiency, and control challenges posed by the dual-gyro system, making the dual-gyro anti-roll technology more practical in engineering and more valuable for promotion.

DETAILED DESCRIPTION

[0023] To make the above-mentioned objects, features, and advantages of the present invention more readily apparent, specific embodiments of the present invention are described in detail below with reference to the accompanying drawings. The following description sets forth numerous specific details to facilitate a full understanding of the present invention. However, the present invention can be implemented in many other ways than those described herein, and those skilled in the art may make similar modifications without departing from the scope of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0024] It should be noted that when a component is referred to as being "fixed to" or "disposed on" another component, it may be directly on the other component or there may be a central component. When a component is considered to be "connected to" another component, it may be directly connected to the other component or there may be a central component at the same time. The terms "vertical", "horizontal", "upper", "lower", "left", "right" and similar expressions used in the specification of the present invention are for illustrative purposes only and do not represent the only implementation method.

[0025] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of the technical features being referred to. Thus, a feature defined as "first" or "second" may explicitly or implicitly include at least one such feature. In the description of the present invention, "plurality" means at least two, such as two, three, etc., unless otherwise specifically defined.

[0026] In the present invention, unless otherwise expressly specified or limited, when a first feature is "above" or "below" a second feature, it can mean that the first feature is directly in contact with the second feature, or the first feature and the second feature are in contact indirectly through an intermediary. Furthermore, when a first feature is "above," "above," or "above" a second feature, it can mean that the first feature is directly above or diagonally above the second feature, or simply means that the first feature is higher in level than the second feature. When a first feature is "below," "below," or "below" a second feature, it can mean that the first feature is directly below or diagonally below the second feature, or simply means that the first feature is lower in level than the second feature.

[0027] Unless otherwise defined, all technical and scientific terms used in the present description have the same meanings as those commonly understood by those skilled in the art to which this invention pertains. The terms used in this description are for the purpose of describing specific embodiments only and are not intended to limit the present invention. The term "and / or" as used in this description includes any and all combinations of one or more of the associated listed items.

[0028] The present invention seeks to protect a dual-gyro anti-roll device, which is used in ships. The frame 10 of the dual-gyro anti-roll device 100 is fixed to an object on the ship that needs to be anti-rolled, so as to improve the stability of the ship during navigation.

[0029] A gyro stabilizer primarily utilizes the inherent stability of its high-speed rotating rotor to achieve roll reduction. When the gyro rotor oscillates in one direction (called precession), it generates a torque perpendicular to the precession axis. The magnitude of this torque is proportional to the gyro rotor's rotational speed, its moment of inertia about its axis of rotation, and the precession speed. Therefore, the larger the gyro rotor, the higher its rotational speed, and the faster its precession speed, the greater the torque.

[0030] See also Figures 1 to 5 A dual-gyro anti-roll device 100 provided by one embodiment of the present invention includes a frame 10, a transmission mechanism 20 mounted on the frame 10, a driver 40, and two gyro rotors 30. One of the two gyro rotors 30 is provided with a first rotor shaft 31, and the other is provided with a second rotor shaft 32. The first rotor shaft 31 and the second rotor shaft 32 are rotatably connected to the frame 10 via bearings or sleeves. The transmission mechanism 20 is respectively in transmission connection with the first rotor shaft 31, the second rotor shaft 32, and the output shaft 41 of the driver 40, so that the two gyro rotors 30 rotate in opposite directions at the same speed under the drive of the driver 40.

[0031] With this arrangement, the driver 40 acts as a power source, simultaneously driving both gyro rotors 30 to rotate at the same speed in opposite directions. In other words, both gyro rotors 30 are driven by the same driver 40, ensuring that their speeds are strictly consistent and their directions are opposite. Speed synchronization is a prerequisite for offsetting precession interference. This eliminates the need for a corresponding driver 40 for each gyro rotor 30, reducing the number of drivers 40 and improving space utilization. While maintaining the same total angular momentum, the speed and size of each gyro rotor in the dual gyro can be reduced, lowering the performance requirements for components such as bearings and motors. This reduces the load on these components, lowers the failure rate, and extends maintenance cycles.

[0032] like Figure 1 and Figure 2 As shown, in one embodiment, the frame 10 further includes a first side plate 11, a second side plate 12, and a support frame 13. The first side plate 11 and the second side plate 12 are connected by a connecting column 14. The second side plate 12 is hollow. The support frame 13 is fixed to the second side plate 12 by bolts or pins and is located in the hollow position of the second side plate 12. The two gyro rotors 30 are located between the first side plate 11 and the second side plate 12, and one end of the first rotor shaft 31 is rotatably connected to the first side plate 11 via a bearing or a bushing, and the other end of the first rotor shaft 31 is rotatably connected to the support frame 13 via a bearing or a bushing.

[0033] The drive member 40 and transition shaft 27 are mounted on the first side plate 11. One end of the first rotor shaft 31 passes through the first side plate 11 and is keyed to the first synchronous wheel 21. There are two support frames 13, each rotatably connected to the first rotor shaft 31 and the second rotor shaft 32.

[0034] like Figure 1 and Figure 3 As shown, in one embodiment, the transmission mechanism 20 includes a first synchronous wheel 21, a second synchronous wheel 22, a third synchronous wheel 23, and a transmission belt 24. The first synchronous wheel 21 is connected to the output shaft 41, the second synchronous wheel 22 is in transmission connection with the second rotor shaft 32, and the third synchronous wheel 23 is connected to the first rotor shaft 31. The transmission belt 24 engages with the first synchronous wheel 21, the second synchronous wheel 22, and the third synchronous wheel 23, respectively, so that the first synchronous wheel 21, driven by the output shaft 41, simultaneously drives the second synchronous wheel 22 and the third synchronous wheel 23 to rotate. Through the rational arrangement of the first synchronous wheel 21, the second synchronous wheel 22, the third synchronous wheel 23, and the transmission belt 24, the transmission mechanism 20 simultaneously drives the first rotor shaft 31 and the second rotor shaft 32 to rotate. As a result, the first synchronous wheel 21, driven by the output shaft 41, drives the second synchronous wheel 22 and the third synchronous wheel 23 to rotate via the transmission belt 24, thereby causing the two gyro rotors 30 to rotate at the same speed, thereby improving mechanical synchronization.

[0035] Preferably, the first synchronous wheel 21 is keyed to the output shaft 41, the third synchronous wheel 23 is keyed to the first rotor shaft 31, and the transmission belt 24 is configured as a synchronous toothed belt. Of course, the key connection can also be replaced with a pin connection or a spline connection, and the transmission belt 24 can also be a roller chain.

[0036] Without being limited thereto, in other embodiments, the transmission of the first synchronous wheel 21 , the second synchronous wheel 22 , and the third synchronous wheel 23 through the transmission belt 24 may be replaced by transmission through gear meshing, which will not be elaborated herein.

[0037] like Figure 6 Furthermore, the transmission mechanism 20 includes a first gear 25, a second gear 26, and a transition shaft 27. The first gear 25 meshes with the second gear 26 and is connected to the second rotor shaft 32. The second gear 26 is connected to one end of the transition shaft 27. The second synchronous gear 22 is connected to the other end of the transition shaft 27. The transition shaft 27 drives the second rotor shaft 32 to rotate via the first gear 25 and the second gear 26. Through the rational arrangement of the first gear 25, the second gear 26, and the transition shaft 27, a transmission connection is achieved between the second synchronous gear 22 and the second rotor shaft 32. The second rotor shaft 32 rotates at the same speed as the first rotor shaft 31 but in opposite directions. Arranging the two gyro rotors 30 to rotate in opposite directions helps eliminate the ship's pitch caused by precession, suppresses precession interference, and achieves symmetrical offset.

[0038] Preferably, the first gear 25 is key-connected to the second rotor shaft 32, and the second gear 26 and the second synchronous wheel 22 are key-connected to the transition shaft 27. Of course, the key connection can also be replaced by a pin connection or a spline connection according to needs.

[0039] In this embodiment, the first rotor shaft 31 is set to rotate forward, and the second rotor shaft 32 is set to rotate counterclockwise. Of course, the first rotor shaft 31 can also be set to rotate counterclockwise and the second rotor shaft 32 can be set to rotate forward as needed.

[0040] In one embodiment, the axis of the first rotor shaft 31 is parallel to the axis of the second rotor shaft 32, and the axis of the transition shaft 27 is parallel to the axis of the second rotor shaft 32. It is understood that the lateral moment generated by the precession of a single gyro may cause the pitch of the ship to intensify, and the parallel arrangement can partially offset the hull roll coupling effect caused by the precession of the single gyro.

[0041] In one embodiment, the first rotor shaft 31 and the second rotor shaft 32 are both welded to the corresponding gyro rotor 30, providing a more secure connection. Alternatively, the first rotor shaft 31 and the second rotor shaft 32 can be fixedly connected to the corresponding gyro rotor 30 using integral molding or pin connections, as needed.

[0042] like Figure 6 and Figure 7As shown, in one embodiment, the gyro rotor 30 includes a housing 33 , a rotor body 34 and a rotor motor 35 . The rotor body 34 and the rotor motor 35 are installed inside the housing 33 , and the rotor motor 35 can drive the rotor body 34 to rotate.

[0043] like Figure 7 As shown, further, the shell 33 includes a shell body 331, a shell upper cover 332 and a shell lower cover 333, the shell upper cover 332 and the shell lower cover 333 are respectively covered on both sides of the shell body 331, and the rotor body 34 is rotatably connected to the shell upper cover 332 and the shell lower cover 333 through bearings 341.

[0044] In this embodiment, the driving member 40 is configured as a servo motor. A mounting seat 42 is provided on the servo motor. The servo motor is mounted on the frame 10 via the mounting seat 42 .

[0045] Not limited to this, in other embodiments, the driving member 40 can also be configured as a hydraulic motor, a pneumatic motor or an internal combustion engine.

[0046] In summary, under working conditions, the driving member 40 operates, driving the output shaft 41 to rotate forward, thereby driving the first synchronous gear 21 to start rotating forward. At this time, the synchronous gear system consisting of the first synchronous gear 21, the second synchronous gear 22, the third synchronous gear 23 and the transmission belt 24 rotates at the same speed. The rotation direction of the first synchronous gear 21, the second synchronous gear 22, and the third synchronous gear 23 are all forward, and the corresponding key-connected transition shaft 27 and the first rotor shaft 31 also rotate forward. The transition shaft 27 is key-connected to the second synchronous gear 22 on one side of the first side plate 11 and to the second gear 26 on the other side. The second synchronous gear 22 and the second gear 26 both rotate forward. The first gear 25 and the second gear 26 are meshed and connected by gears. The second gear 26 rotates forward, driving the first gear 25 to rotate reversely, thereby causing the second rotor shaft 32 to rotate reversely. The first rotor shaft 31 and the second rotor shaft 32 are welded to the corresponding gyro rotor 30, ultimately achieving forward rotation of the gyro rotor 30 corresponding to the first rotor shaft 31 and reverse rotation of the gyro rotor 30 corresponding to the second rotor shaft 32.

[0047] In the gyro rotor 30, the rotor body 34 is enclosed by the housing upper cover 332, the housing body 331, and the housing lower cover 333, thanks to bearings 341. The internal rotor motor 35 rotates, driving the rotor body 34 to rotate as well. A shaking object generates a force in the direction of the shaking, which is transmitted to the overall frame 10. The operating transmission mechanism 20 causes one gyro rotor 30 to rotate forward as a whole, while the other gyro rotor 30 rotates counterclockwise, with the rotor bodies 34 inside the gyro rotors 30 rotating forward and counterclockwise, respectively. By leveraging the gyroscopic effect, the dual-gyro anti-roll device 100 generates a force in the opposite direction of the frame 10's shaking, thereby reducing the shaking effect.

[0048] The technical features of the above-mentioned embodiments can be combined arbitrarily. In order to make the description concise, not all possible combinations of the technical features in the above-mentioned embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0049] The above-described embodiments merely represent several implementation methods of the present invention. While the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent. It should be noted that a person skilled in the art would be able to make various modifications and improvements without departing from the spirit of the present invention, all of which fall within the scope of protection of the present invention. Therefore, the scope of patent protection for the present invention shall be determined by the appended claims.
