Detailed Implementation

[0041] The technical solutions of this disclosure will be further described in detail below through embodiments and in conjunction with the accompanying drawings. In this specification, the same or similar reference numerals indicate the same or similar components. The following description of the embodiments of this disclosure with reference to the accompanying drawings is intended to explain the overall inventive concept of this disclosure and should not be construed as a limitation thereof.

[0042] It should be noted that this disclosure was made by the inventors based on the following facts, problems, and discoveries: In related technologies, when anti-roll gyroscopes reduce the roll of ships, they need to rotate the flywheel at high speed to obtain a large angular momentum. The bearings supporting the flywheel will generate a lot of heat. When the heat of the bearings cannot be effectively dissipated, the bearing temperature will rise sharply, which will lead to poor bearing lubrication, increased flywheel vibration, or even seizure.

[0043] Secondly, the flywheel of the anti-roll gyroscope also suffers from problems such as high wind resistance affecting the output anti-roll torque, and the motor and other actuators being prone to corrosion and damage.

[0044] Based on the problems and facts discovered above, the inventors of this disclosure propose a rocking reduction device.

[0045] like Figure 1 As shown, the anti-roll device 100 disclosed herein includes a flywheel 1, an actuator 2, and a housing 3.

[0046] The flywheel 1 can be shaped like a wheel. After installation, the flywheel 1 has two axes of rotation, such as... Figure 1 As shown, one of the rotation axes is the rotation axis of flywheel 1, specifically it can be... Figure 1 The A axis in the flywheel 1 can be arranged horizontally, and the rotation axis can also be regarded as the central axis of the flywheel 1. In use, the flywheel 1 can rotate around this axis.

[0047] Another axis of rotation can be the precession axis of flywheel 1, specifically it can be... Figure 1 The B-axis and the precession axis can be arranged vertically.

[0048] The actuator 2 includes a slewing support 21 and a side support 24. The rotation axis of the slewing support 21 extends vertically. The side support 24 is connected to the upper end of the slewing support 21 and is rotatably connected to the flywheel 1 via a bearing 11. The flywheel 1 can be driven to rotate around a horizontally extending axis of rotation A. The slewing support 21 can be driven to cause the side support 24 and the flywheel 1 on the side support 24 to rotate and oscillate around a vertically extending precession axis B. In use, under the action of an external drive, the flywheel 1 can precess and oscillate around the precession axis B while rotating at high speed around the axis of rotation A, and output a damping torque in a direction perpendicular to both the precession axis B and the axis of rotation A.

[0049] Both the flywheel 1 and the actuator 2 are installed inside the housing 3. There is a medium groove 30 between the rotary support 21 and the housing 3. The medium groove 30 stores the heat dissipation medium 5. At least part of the rotary support 21 and the heat dissipation medium 5 form a heat dissipation path for the heat generated by the flywheel 1 during operation to dissipate to the housing 3.

[0050] For example, such as Figure 1 and Figure 2 As shown, the slewing support 21 can be a ring structure. The part of the slewing support 21 used to drive the flywheel 1 to swing can be rotatably assembled inside the housing 3. Specifically, it can be arranged to extend circumferentially around the aforementioned axis B, and an annular medium groove 30 can be formed between this part and the inner wall of the housing 3. The medium groove 30 is used to store the heat dissipation medium 5. The heat dissipation medium 5 can be a coolant, cooling oil, or other media with thermal conductivity and flow properties.

[0051] During the rotation and / or oscillation of the flywheel 1, heat is generated at the rotational assembly positions of the flywheel 1 and the side support 24, as well as the rotational assembly positions of the slewing support 21 and the housing 3. This heat is conducted through the side support 24 to the slewing support 21, then through the slewing support 21 to the heat dissipation medium 5, and finally through the heat dissipation medium 5 to the housing 3. The heat can then be quickly dissipated through the outer wall of the housing 3. For the specific heat dissipation path, please refer to [link to relevant documentation]. Figure 1 The path indicated by the black arrow in the image.

[0052] This avoids the situation where the heat of the bearing 11 and the like in the rotating assembly position cannot be effectively dissipated, thereby avoiding the situation where the bearing 11 is poorly lubricated, the flywheel 1 vibrates more or even seizes due to the high temperature of the bearing 11 and the like.

[0053] Secondly, since the flywheel 1 and the actuator 2 are assembled inside the housing 3, the housing 3 can protect the flywheel 1 and the actuator 2, preventing the actuator 2 from being directly exposed to the outside. This avoids the interference and corrosion of the actuator 2 and the flywheel 1 by rainwater, condensation, salt spray and seawater, reducing the overall failure rate and ensuring the stability of the overall operation.

[0054] Since both the flywheel 1 and the actuator 2 are protected by the housing 3, the anti-roll device 100 can be installed in relatively harsh environments, which improves the installation limitations of the anti-roll device 100 in related technologies and enhances the ease of installation.

[0055] In addition, the slewing support 21 can also agitate the heat dissipation medium 5 during rotation, thereby allowing heat to be quickly and evenly distributed into the heat dissipation medium 5, thus improving the heat dissipation effect.

[0056] The flywheel 1 and the actuator 2 are located in the same space, which is conducive to the optimized layout and rational utilization of the overall structure. The anti-sway device 100 disclosed in this invention also has the advantages of compact structure and simplification.

[0057] In some embodiments, the medium tank 30 is located at the bottom of the housing 3, and at least part of the rotary support 21 is immersed in the heat dissipation medium 5. For example, as Figure 1 As shown, the B axis of the flywheel 1 can be arranged to extend in the vertical direction. At this time, the space at the bottom of the housing 3 located on the periphery of the slewing support 21 forms a medium groove 30.

[0058] Heat from the bearing 11 on the side support 24 is transferred to the slewing support 21 via the side support 24. Since the heat dissipation medium 5 immerses at least part of the slewing support 21, the slewing support 21 can transfer heat to the heat dissipation medium 5, which in turn transfers the heat to the housing 3 and dissipates it. Both the slewing support 21 and the medium groove 30 are located at the bottom of the housing 3. The heat dissipation medium 5 automatically gathers in the medium groove 30 under the action of gravity, ensuring that the slewing support 21 can always maintain good contact with the heat dissipation medium 5, thereby ensuring heat dissipation performance.

[0059] Secondly, the heat dissipation medium 5 is located at the bottom of the housing 3, which can also lower the center of gravity of the anti-sway device 100, thus improving the stability of the structure. In some embodiments, the slewing support 21 divides the space inside the housing 3 into an internal space 312 and an external space 313. The external space 313 is located on the periphery of the internal space 312, and the flywheel 1 is located in the internal space 312. At least a portion of the external space 313 forms a medium groove 30, and the slewing support 21 between the medium groove 30 and the internal space 312 seals and isolates the medium groove 30 and the internal space 312.

[0060] For example, such as Figure 3As shown, the slewing support 21 can be a ring structure. Along the horizontal radial direction of the housing 3, the slewing support 21 can divide the internal space 312 of the housing 3 into an internal space 312 and an external space 313. The external space 313 can be ring-shaped and located on the periphery of the slewing support 21, while the internal space 312 can be located inside the slewing support 21.

[0061] The flywheel 1 can be located in the internal space 312, while the bottom part of the external space 313 can form the medium groove 30. In the radial direction of the housing 3, the rotary support 21 located between the medium groove 30 and the internal space 312 has good sealing performance, thereby sealing and isolating the internal space 312 and the external space 313.

[0062] This prevents the heat dissipation medium 5 from flowing into the internal space 312. On the one hand, it allows the heat dissipation medium 5 to accumulate in a local fixed position, preventing the loss of the heat dissipation medium 5. On the other hand, it also prevents the heat dissipation medium 5 from contacting components such as the flywheel 1 in the internal space 312, thereby preventing the heat dissipation medium 5 from affecting the rotation of the flywheel 1 and causing obstruction.

[0063] In some embodiments, the slewing support 21 includes a fixed part 211 and a rotating part 212. The fixed part 211 is connected to or integrally formed with the housing 3. The rotating part 212 is rotatably mounted on the outer periphery of the fixed part 211. The flywheel 1 is connected to the rotating part 212 so that the rotating part 212 drives the flywheel 1 to swing around the precession axis. At least a portion of the medium groove 30 surrounds the periphery of the rotating part 212, and at least a portion of the rotating part 212 is immersed in the heat dissipation medium 5.

[0064] For example, such as Figure 3 and Figure 7 As shown, both the fixing part 211 and the rotating part 212 can be annular structures. The fixing part 211 can be an inner ring, and the rotating part 212 can be an outer ring rotatably assembled on the outer periphery of the inner ring. The fixing part 211 can be connected and fixed to the bottom wall of the housing 3 by fasteners such as screws. In some other embodiments, the fixing part 211 can also be integrally formed with the housing 3.

[0065] The aforementioned flywheel 1 can be indirectly connected to the rotating part 212 via the side support 24, such as... Figure 4 As shown, the medium tank 30 can be distributed on the outer side of the rotating part 212. Figure 4On the left side and bottom side of the rotating part 212, after the medium tank 30 is filled with heat dissipation medium 5, the outer wall surface and the bottom side wall of the rotating part 212 can both contact the heat dissipation medium 5, so that the heat conducted to the rotating part 212 can also be dissipated to the outside of the housing 3 through the heat dissipation medium 5 and the housing 3. In some embodiments, a first seal 6 is provided between the fixing part 211 and the housing 3, and the first seal 6 is adapted to prevent the heat dissipation medium 5 from flowing into the inside of the fixing part 211.

[0066] For example, such as Figure 4 As shown, the first seal 6 can be a static seal, specifically a sealing ring, sealant, etc. The first seal 6 can be annular, thereby ensuring the contact sealing between the bottom surface of the fixing part 211 and the upper surface of the bottom wall of the housing 3, and preventing the heat dissipation medium 5 from entering the internal space 312 through the gap 214 between the fixing part 211 and the housing 3.

[0067] In some embodiments, a second seal 7 is provided between the fixed part 211 and the rotating part 212. The second seal 7 is a rotary seal and is adapted to prevent the heat dissipation medium 5 from flowing through the gap 214 between the fixed part 211 and the rotating part 212.

[0068] For example, such as Figure 4 As shown, the second seal 7 can be a dynamic seal and can be annular. The second seal 7 is assembled at the annular gap 214 formed between the outer wall surface of the fixed part 211 and the inner wall surface of the rotating part 212, thereby achieving rotational sealing at the gap 214. The second seal 7 prevents the heat dissipation medium 5 from flowing into the internal space 312 through the gap 214.

[0069] In some embodiments, the rotary support 21 includes a rolling element 213 located between the fixed portion 211 and the rotating portion 212, and the rolling element 213 is disposed in a portion of the gap 214 between the medium groove 30 and the second seal 7.

[0070] For example, such as Figure 4 As shown, the rolling element 213 can be a ball, roller, etc. There are multiple rolling elements 213, all of which are movably assembled in the above-mentioned gap 214. The gap 214 is annular, and the multiple rolling elements 213 can be arranged at equal intervals along the circumference of the gap 214.

[0071] The gap 214 is connected to the medium groove 30. In the vertical direction, the rolling element 213 can be located below the second seal 7, so that the heat dissipation medium 5 can flow to the rolling element 213. This can reduce the friction at the rolling element 213 and allow the heat dissipation medium 5 to reach the heat-generating part, thereby improving the heat dissipation effect.

[0072] In some embodiments, the slewing support 21 includes a heat-conducting element 26 connected between the side support 24 and the rotating part 212. At least a portion of the heat-conducting element 26 is immersed in the heat dissipation medium 5. A third seal 8 is provided between the heat-conducting element 26 and the rotating part 212. The third seal 8 is adapted to prevent the heat dissipation medium 5 from flowing to the inside of the rotating part 212 via the heat-conducting element 26.

[0073] For example, such as Figure 3 and Figure 4 As shown, the heat-conducting element 26 can be a ring structure. The heat-conducting element 26 can be fixed on the upper side of the rotating part 212 of the ring. When the medium tank 30 is filled with the heat dissipation medium 5, the heat dissipation medium 5 can completely or partially immerse the heat-conducting element 26, so that the generated heat can be quickly dissipated to the heat dissipation medium 5 by means of the better thermal conductivity of the heat-conducting element 26.

[0074] like Figure 4 As shown, a third seal 8 can be provided between the lower surface of the heat-conducting component 26 and the upper surface of the rotating part 212. The third seal 8 is a static seal and is annular. The provision of the third seal 8 prevents the heat dissipation medium 5 from flowing to the internal space 312 through the heat-conducting component 26 and the rotating part 212.

[0075] It should be noted that, since the bearing 11 at the rotating assembly of the central shaft of the flywheel 1 and the rotating support 21 is the main heat source, the heat at the bearing 11 is first conducted to the heat-conducting element 26, and then conducted to the rotating part 212 below through the heat-conducting element 26. This makes it easy for the temperature of the upper layer of the heat dissipation medium 5 to be higher than that of the lower layer. When the rotating part 212 and the heat-conducting element 26 connected to the rotating part 212 agitate the heat dissipation medium 5, the upper and lower layers of the heat dissipation medium 5 can easily exchange heat fully, which can prevent the heat dissipation medium 5 from stratifying in the vertical direction and reducing the lifespan of the heat dissipation medium 5 due to local overheating. At the same time, the agitated heat dissipation medium 5 will have forced flow relative to the heat-conducting element 26, the rotating part 212 and the shell 3, which can significantly improve the heat exchange efficiency between the heat-conducting element 26, the rotating part 212 and the heat dissipation medium 5, and between the heat dissipation medium 5 and the shell 3. In some embodiments, the inner diameter of the heat-conducting element 26 is larger than the inner diameter of the fixed part 211. The heat-conducting component 26 can not only increase the depth of the medium groove 30 that can accommodate the heat dissipation medium 5 and increase the heat exchange area of ​​the heat dissipation medium 5 without interfering with the flywheel, but also shorten the heat transfer distance from the bearing 11 to the heat dissipation medium 5 and reduce the thermal resistance between the bearing 11 and the heat dissipation medium 5.

[0076] In some embodiments, the surface of the heat-conducting element 26 that is in contact with the heat dissipation medium 5 is provided with fins 261. For example, such as Figure 4As shown, multiple fins 261 can be provided on the outer peripheral wall of the heat-conducting component 26. Each fin 261 is annular and extends around the circumference of the heat-conducting component 26. The multiple fins 261 can be arranged at intervals in the vertical direction. The fins 261 can increase the heat dissipation area, thereby improving the heat dissipation effect of the heat-conducting component 26.

[0077] In some embodiments, there are two side supports 24, which are arranged opposite each other along the axis of rotation. The flywheel 1 is rotatably mounted on the two side supports 24 via the bearing 11 and is located between the two side supports 24. Each side support 24 is connected to the heat-conducting element 26.

[0078] For example, such as Figure 3 , Figure 6 and Figure 7 As shown, the side support 24 can be in the shape of a vertical plate. The side support 24 can be located at one end of the extension direction of the central shaft of the flywheel 1. The central shaft can be rotatably assembled with the side support 24 through the bearing 11.

[0079] The bottom side of the side support 24 can be directly connected and fixed to the rotating part 212.

[0080] There are two side supports 24, which are arranged opposite each other along the rotation axis of the flywheel 1. The flywheel 1 is rotatably mounted between the two side supports 24.

[0081] For example, such as Figure 3 As shown, the two side supports 24 can be arranged opposite each other and spaced apart in the left and right directions. The left end of the central shaft of the flywheel 1 can be rotatably assembled with the left side support 24, and the right end of the central shaft of the flywheel 1 can be rotatably assembled with the right side support 24.

[0082] In use, the flywheel 1 can rotate around axis A relative to the side support 24. At the same time, the flywheel 1 and the side support 24 can also rotate synchronously with the rotating part 212, thereby realizing the oscillation of the flywheel 1 around axis B.

[0083] In some embodiments, the side support 24 is made of aluminum alloy. Aluminum alloy has lower thermal resistance than steel, which is beneficial for quickly transferring the temperature of the bearing 11 to the heat conductor 26.

[0084] In some embodiments, a shoulder 301 is provided in the medium tank 30, which divides the medium tank 30 into a first tank 302 and a second tank 303. The first tank 302 is located on the outer periphery of the second tank 303. The second tank 303 communicates with the gap 214 between the rotating part 212 and the fixed part 211. The rotating part 212 is opposite to the shoulder 301 and arranged at intervals in the direction of the precession axis.

[0085] For example, such as Figure 4 and Figure 5As shown, the shoulder 301 can be annular and integrally formed on the upper side of the bottom shell wall of the housing 3. In the radial direction of the housing 3, the shoulder 301 can divide the medium groove 30 into a first groove 302 and a second groove 303. Both the first groove 302 and the second groove 303 can be annular. The first groove 302 is located outside the second groove 303, and the bottom of the aforementioned gap 214 communicates with the second groove 303.

[0086] like Figure 5 As shown, the lower surfaces of the shoulder 301 and the rotating part 212 can be spaced apart to form a flow channel 304, which connects the first groove 302 and the second groove 303.

[0087] The shoulder 301 is designed so that the heat dissipation medium 5 in the second groove 303 is less affected by agitation than the heat dissipation medium 5 in the first groove 302. This prevents impurities in the first groove 302 from being agitated and rolled into the second groove 303 and the aforementioned gap 214. Consequently, it prevents impurities from entering the raceway between the rolling element 213 and the fixed part 211, as well as between the rolling element 213 and the rotating part 212, which would accelerate the wear of the rotary support 21.

[0088] In some embodiments, the medium tank 30 is connected to the gap 214 between the rotating part 212 and the fixed part 211, and the liquid level of the heat dissipation medium 5 in the medium tank 30 is higher than the liquid level in the gap 214.

[0089] For example, such as Figure 4 As shown, it is located on the outside of the rotating part 212 and the heat-conducting member 26. Figure 4 The liquid level of the heat dissipation medium 5 on the left side of the slit 214 is higher than that of the heat dissipation medium 5 in the slit 214. In this way, under the action of gravity, the heat dissipation medium 5 can always have a flow tendency to fill the slit 214 below the second seal 7, thereby fully ensuring the heat dissipation and lubrication effect between the rotating part 212 and the fixed part 211.

[0090] In some embodiments, the actuator 2 further includes a first drive 22, the first drive 22 includes a drive wheel 221, the drive wheel 221 is connected to the slewing support 21 to drive the side support 24 and the flywheel 1 to rotate about the precession axis extending in the vertical direction, and at least a portion of the drive wheel 221 is located in the medium tank 30 and immersed in the heat dissipation medium 5.

[0091] For example, such as Figure 2 As shown, the first drive 22 may include a motor and a drive wheel 221. The drive wheel 221 may be a gear. The drive wheel 221 may mesh with the outer peripheral side of the rotating part 212, so that the rotation of the rotating part 212 can be driven by the rotation of the drive wheel 221.

[0092] When the medium tank 30 is filled with the heat dissipation medium 5, the heat dissipation medium 5 can completely or partially immerse the drive wheel 221. This can enhance the heat dissipation and lubrication effect between the drive wheel 221 and the rotating part 212, and also reduce the noise generated when the drive wheel 221 and the rotating part 212 mesh and transmit. After the noise of the sway reduction device 100 is reduced, it is convenient to install the sway reduction device 100 in an area close to people's activity area, further reducing the restriction on the installation area.

[0093] In some embodiments, the anti-sway device 100 further includes a base 35 connected to the bottom of the housing 3. The base 35 and / or the bottom of the housing 3 are provided with a cooling water channel. The base and the bottom of the housing cover each other to form a cooling water channel. The cooling water channel is adapted to allow cooling water to pass through it to exchange at least a portion of the heat of the cooling medium inside the housing 3.

[0094] After the heat from the bearing 11 is transferred to the heat dissipation medium 5 via the side support 24 and the slewing support 21, part of the heat from the heat dissipation medium 5 is dissipated to the outside air through the housing 3, and another part of the heat is transferred to the cooling water circuit through the housing 3. The cooling water in the cooling water circuit can exchange some of the heat from the heat dissipation medium 5, which can effectively reduce the thermal resistance of the heat dissipation medium 5 to dissipate heat through the housing 3, thereby further reducing the operating temperature of the bearing 11.

[0095] In some embodiments, the cooling water channel has an inlet 91, an outlet 92 and a heat exchange section 93. The inlet 91 and the outlet 92 are located at the bottom edge of the housing 3, and the heat exchange section 93 is connected between the inlet 91 and the outlet 92. At least a portion of the heat exchange section 93 extends zigzag along the outer periphery of the rotary support 21.

[0096] like Figure 10 As shown, the inlet 91 and outlet 92 are located on one side of the bottom edge of the housing 3. The inlet 91 is suitable for introducing coolant, such as water or coolant. The coolant flows in a tortuous manner along the extension direction of the heat exchange section 93, which can transfer the heat from the cooling medium 5 on the periphery of the rotating support 21 to the housing 3 to the coolant. The coolant with heat flows out from the outlet and is carried away.

[0097] In some embodiments, the housing 3 contains a sealed space 31, which can be a vacuum. The flywheel 1 and the actuator 2 are both installed within the sealed space 31. For example, ... Figure 1 As shown, the housing 3 can be a rectangular parallelepiped structure, and the space inside the housing 3 can be a relatively sealed sealed space 31. The flywheel 1 and the actuator 2 mentioned above are both installed inside the housing 3.

[0098] The flywheel 1 is assembled in the sealed space 31 of the housing 3. Since the sealed space 31 is a vacuum environment with relatively rarefied gas, the rotational resistance and wind resistance exerted on the flywheel 1 by the gas during rotation are small. This can increase the angular momentum and speed of the flywheel 1, improve the overall anti-roll performance, and also help reduce the overall energy consumption, thus achieving energy saving in the anti-roll process.

[0099] In some embodiments, such as Figure 6 As shown, the slewing support 21 is disposed inside the housing 3 and can be installed and fixed to the bottom wall of the housing 3. A portion of the slewing support 21 can rotate freely relative to the housing 3, and the axis of rotation of this portion of the slewing support 21 can be axis B. The flywheel 1 can be directly or indirectly connected to the rotating part 212 of the slewing support 21.

[0100] The first drive 22 can be located on the side of the flywheel 1. The first drive 22 can include a motor, a drive wheel 221 and a fixed base 222. The fixed base 222 can be directly connected and fixed to the bottom wall of the housing 3. The drive wheel 221 can be located inside the fixed base 222. The output shaft of the motor can be connected to the drive wheel 221. The drive wheel 221 can be a gear and can mesh with the rotating part 212 of the slewing support 21.

[0101] In use, the first drive 22 can drive the drive wheel 221 to rotate, and the rotating drive wheel 221 can drive the rotating part 212 of the slewing support 21 to rotate, thereby driving the flywheel 1 to swing around the axis B.

[0102] A gear that meshes with the drive wheel 221 may be provided on the outer periphery of the rotating part 212. The flywheel 1 may be located above the slewing support 21, and the flywheel 1 may be connected and fixed to the rotating part 212 via the side support 24, so that when the drive wheel 221 drives the rotating part 212 to rotate, the flywheel 1 may oscillate around the B axis.

[0103] In some embodiments, the actuator 2 further includes a second drive 27 and a conductive component 23. The second drive 27 includes a stator 271 and a rotor 272 that can be driven to rotate by the stator 271. The stator 271 is connected to the side support 24, and the rotor 272 is connected to the flywheel 1. The second drive 27 is adapted to drive the flywheel 1 to rotate. The conductive component 23 includes a rotating component 232 and a stationary component 231. The stationary component 231 is directly or indirectly connected to the housing 3, and the rotating component 232 is connected to the rotating part 212.

[0104] For example, such as Figure 7 As shown, a ring groove can be provided on the right side of the flywheel 1, and the rotor 272 can be embedded in the ring groove of the flywheel 1 and connected and fixed to the central shaft of the flywheel 1. The stator 271 is connected to the side support 24 and surrounds the outer periphery of the rotor 272.

[0105] When the second drive 27 is energized, the stator 271 drives the rotor 272 and the flywheel 1 connected to the rotor 272 to rotate around the rotation axis A.

[0106] The conductive component 23 can be a conductive slip ring, such as... Figure 8 As shown, the stationary part 231 and the rotating part 232 of the conductive component 23 are coaxially rotated and assembled, and the rotating part 232 and the stationary part 231 are always electrically connected. The stationary part 231 can be directly connected to the housing 3, or it can be connected to the housing 3 through the built-in part 4 mentioned later. When the flywheel 1 is running, the stationary part 231 remains stationary relative to the housing 3.

[0107] The rotating component 232 can be connected and fixed to the aforementioned rotary support 21 via a rotating bracket 25 connected to the side support 24, and the rotation axis of the rotating component 232 is axis B.

[0108] When the flywheel 1 oscillates, the rotating member 232 rotates relative to the stationary member 231, and the rotating member 232 and the stationary member 231 maintain an electrical connection to supply power to the second drive 27.

[0109] In use, the rotating part 232 can rotate synchronously with the rotating part 212, and the rotating part 232 can also be electrically connected to the second drive 27 through a wire, thereby satisfying the use requirement of supplying current to the second drive 27 to drive the second drive 27 to operate when the second drive 27 rotates and swings around the precession axis B.

[0110] In some embodiments, the cross section of the housing 3 perpendicular to the advance axis has a length direction, and the actuator 2 further includes a first drive 22 for driving the rotary support 21. The first drive 22 is provided with at least one, and at least one first drive 22 is located on one side of the flywheel 1 in the length direction.

[0111] For example, such as Figure 6 and Figure 8 As shown, the housing 3 can be a rectangular parallelepiped structure. The cross-section perpendicular to the precession axis of the flywheel 1 can be a horizontal plane. Within this horizontal plane, the housing 3 has a length direction and a width direction. Specifically, the length direction can be the front-to-back direction, and the width direction can be the left-to-right direction.

[0112] The aforementioned first drive 22 can be provided in two forms. In some other embodiments, the first drive 22 can also be provided in one, three, or other quantities. Both first drives 22 can be located on the rear side of the flywheel 1.

[0113] The flywheel 1 is offset from the center of the housing 3 in the front-rear direction and is closer to the front side, while the first drive 22 is located on the rear side. This arrangement allows the housing 3 to be larger only in the length direction and smaller in the width direction. The anti-roll device 100 can be compactly formed into a roughly rectangular shape. When installing the anti-roll device 100, it can be easily adapted to the case where the hatch of the ship's cabin is longer in a certain direction, thereby facilitating the installation and arrangement of the anti-roll device 100 in narrow spaces.

[0114] In some embodiments, the rotation angle of the rotating member 232 relative to the stationary member 231 about the precession axis of the flywheel 1 is ±70 to ±90°. This satisfies the need for large-angle adjustment of the flywheel 1 in the circumferential direction. After allowing the flywheel 1 to rotate and oscillate at large angles, the flywheel 1 can have a longer braking distance when controlled. The flywheel 1 can be allowed to have a faster precession speed and has a better anti-roll effect.

[0115] In some embodiments, the rotating member 232 is mounted on the rotating bracket 25, specifically at the center of the top side of the rotating bracket 25.

[0116] In some embodiments, the anti-sway device 10 further includes a carrier 41 connected to the housing 3, and a stationary member 231 connected to the carrier 41. For example, as Figure 6 and Figure 7 As shown, the carrier 41 can be a plate-like structure, and the carrier 41 can be directly or indirectly connected and fixed to the inner wall of the housing 3. The aforementioned stationary component 231 can be connected and fixed to the carrier 41.

[0117] In some embodiments, the carrier 41 is disposed on the side of the flywheel 1 away from the rotary support 21 of the actuator 2 along the direction of the precession axis, and a receiving space 311 suitable for accommodating electrical components is defined between the carrier 41 and the housing 3.

[0118] For example, such as Figure 6 and Figure 7 As shown, the carrier 41 can be disposed on the top side of the flywheel 1, and a portion of the sealed space 31 between the top side of the carrier 41 and the shell wall of the top side of the housing 3 can form a receiving space 311. Some electrical components such as circuit boards and controllers can be installed in the receiving space 311 and connected and fixed to the upper surface of the carrier 41, thereby facilitating the installation of electrical components and realizing the full utilization of the sealed space 31 and the division of the space into functional areas. At the same time, the carrier 41 is located on the side of the flywheel 1 away from the rotary support 21. When the rotary support 21 agitates the heat dissipation medium 5, the splashed heat dissipation medium 5 is far away from the carrier 4 and blocked by the carrier 4. The splashed heat dissipation medium 5 will not enter the receiving space 311 containing electrical components and affect the electrical components.

[0119] In some embodiments, the anti-sway device 100 further includes a plurality of rods 42, which are arranged at circumferential intervals along the flywheel 1 and are connected between the carrier 41 and the housing 3.

[0120] For example, such as Figures 6 to 8 As shown, the rod 42 can be a square rod structure, and there can be four rods 42, which can be set at the four corners of the flywheel 1.

[0121] The extension direction of the rod 42 is consistent with the direction of the precession axis, that is, each rod 42 can extend along the extension direction of axis B. The top end of each rod 42 can be connected and fixed to the aforementioned carrier 41, and the bottom end of each rod 42 can be connected and fixed to the bottom wall of the housing 3.

[0122] The arrangement of the rod 42 facilitates the support and installation of the carrier 41. On the other hand, the rod 42 occupies a small space, which is conducive to its flexible arrangement in various positions around the flywheel 1.

[0123] In some embodiments, the housing 3 includes a first housing 36 and a second housing 37. The first housing 36 can be closed with the second housing 37 along the precession axis B to form a sealed space. Part of the actuator 2 and the flywheel 1 are housed in the second housing 37, and another part of the actuator 2 and the flywheel 1 are housed in the first housing 36.

[0124] like Figure 2 , Figure 3 , Figure 6 and Figure 8 The anti-sway device 100 is in the state after the first shell 36 is removed. When the first shell 36 and the second shell 37 are separated, the carrier 41 is spaced above the second shell 37 and forms a communication space in the circumference of the carrier 41 that connects the second shell 36 to the outside. When only the first shell 36 is opened, personnel can easily perform maintenance on the inside of the anti-sway device 100 through this communication space, such as replacing the heat dissipation medium 5, tightening screws, and observing the engagement status of the slewing support 21 and the drive wheel 221 of the first drive 22.

[0125] In some embodiments, the rod 42 is provided with at least one first protrusion 421, and the inner wall of the housing 3 is provided with at least one second protrusion 372, wherein the first protrusion 421 is adapted to be connected to the second protrusion 372.

[0126] For example, such as Figure 6 As shown, each rod 42 may be provided with two first protrusions 421, one of which may be located in the middle of the rod 42 and the other may be located at the bottom of the rod 42.

[0127] The inner wall of the shell 3 can also be provided with two second protrusions 372 corresponding to each rod 42. These two second protrusions 372 can overlap and be fixed with the two first protrusions 421 respectively, thereby improving the overall structural stability and structural strength of the shell 3.

[0128] In some embodiments, the housing 3 has an interface 32 on its shell wall, at least a portion of which is adapted to be connected to a vacuum device for adjusting the vacuum level of the sealed space 31.

[0129] like Figure 6 As shown, the side wall of the housing 3 may also be provided with an interface 32. Multiple interfaces 32 may be provided, and at least one interface 32 may be connected to a vacuum device such as a vacuum pump for evacuation. In use, the corresponding interface 32 can be connected to the vacuum device first. With the help of the vacuum device, the sealed space 31 can be evacuated, thereby enabling the adjustment of the vacuum degree of the sealed space 31. After evacuation is completed, the interface 32 needs to be sealed.

[0130] In some embodiments, the outer wall surface of the housing 3 is provided with a receiving groove 33, and the interface 32 is disposed within the receiving groove 33. For example, Figure 6 As shown, the receiving groove 33 can be a rectangular groove and can be set on the rear shell wall of the housing 3. The receiving groove 33 can extend in the vertical direction. The aforementioned interface 32 can be located inside the receiving groove 33, thereby avoiding the situation where the interface 32 protrudes from the outer surface of the housing 3, further realizing the compactness of the overall structure and facilitating the installation and arrangement of the anti-sway device 100.

[0131] In some embodiments, interface 32 includes a vacuum interface 321 and an electrical interface 322. The vacuum interface 321 is adapted to be connected to a vacuum device, and both the vacuum interface 321 and the electrical interface 322 are disposed in the receiving groove 33.

[0132] For example, such as Figure 6 As shown, there can be one vacuum interface 321 and two electrical interfaces 322. Both electrical interfaces 322 can be located below the vacuum interface 321, and both electrical interfaces 322 can be used to connect to an external power source, thereby meeting the power supply requirements for the first drive 22, the second drive 27, etc.

[0133] In some embodiments, a portion of the shell wall of the housing 3 protrudes into the sealed space 31 to form a receiving groove 33 on the outside of the housing 3 and a boss 34 on the inside of the housing 3, the boss 34 being connected to the carrier 41 of the built-in component 4.

[0134] For example, such as Figure 6As shown, a portion of the rear shell wall of the housing 3 can protrude inwards, thereby forming a receiving groove 33 on the outer side of the rear shell wall of the housing 3, and a boss 34 on the inner side of the rear shell wall of the housing 3. The bottom side of the aforementioned carrier 41 can be connected and fixed to the top side of the boss 34, thereby further improving the stability and structural strength of the overall structure, and also providing support for the carrier 41. Secondly, it also facilitates the forming of the receiving groove 33.

[0135] In some embodiments, the carrier 41 includes a flange extending along the precession axis of the flywheel 1, and the boss 34 supports and secures the flange. For example, as Figure 6 As shown, the front and rear sides of the carrier 41 can each be provided with a downward folded edge, which extends along the vertical direction. The bottom side of each folded edge can be connected and fixed to the corresponding boss 34.

[0136] In some embodiments, the outer wall of the housing 3 is provided with a plurality of spaced-apart stiffeners 38. For example, such as Figure 9 As shown, multiple stiffeners 38 can be integrally formed on the outer wall of the shell 3. The multiple stiffeners 38 can be arranged at intervals along the circumference of the shell 3. The stiffeners 38 can enhance the structural strength of the shell 3 on the one hand, and on the other hand, they can also be used as heat dissipation fins 261, thereby improving the heat dissipation performance of the shell 3.

[0137] In some embodiments, at least a portion of the shell wall of the housing 3 has an arcuate cross-section that bulges outward from the housing 3. For example, as Figure 7 As shown, the cross-sectional shapes of the top, bottom, left, and right sides of the shell 3 can all be arc-shaped, and the arc shape of each shell wall's cross-section bulges outward from the shell 3. This enhances the structural strength and impact resistance of the shell 3.

[0138] In some embodiments, the first shell 36 is provided with a first connecting portion 361, which is located on the outside of the first shell 36 and extends circumferentially along the opening of the first shell 36. The second shell 37 is provided with a second connecting portion 371, which is located on the outside of the second shell 37 and extends circumferentially along the opening of the second shell 37. The first connecting portion 361 and the second connecting portion 371 are connected to assemble the first shell 36 and the second shell 37 into a shell 3.

[0139] For example, such as Figure 7 and Figure 9 As shown, the first connecting part 361 can be integrally formed on the periphery of the opening of the first shell 36, and the second connecting part 371 can be integrally formed on the periphery of the opening of the second shell 37. Both the first connecting part 361 and the second connecting part 371 can be flange structures.

[0140] During assembly, the openings of the first shell 36 and the second shell 37 can be aligned vertically, and then the first connecting part 361 and the second connecting part 371 can be connected and fixed using fasteners. This facilitates the connection and fixation of the first shell 36 and the second shell 37, and the two connecting parts also enhance the structural strength of the mating position of the first shell 36 and the second shell 37.

[0141] In some embodiments, the rotary support 21 of the actuator 2 is installed inside the second housing 37, and a base 35 is provided on the outer side of the second housing 37. The base 35 is arranged opposite to the rotary support 21 on the precession axis of the flywheel 1.

[0142] For example, such as Figure 7 As shown, the slewing support 21 can be installed on the bottom side inside the second shell 37. The base 35 is detachably connected to the second shell 37. The detachable connection between the base 35 and the second shell facilitates the installation and fixation of the anti-sway device 100, while also allowing the installation of cooling water channels at the bottom of the base 35 or the second shell 37.

[0143] The vehicle disclosed herein is described below.

[0144] The vehicle disclosed herein includes the roll reduction device 100 as described in any of the above embodiments. Specifically, the vehicle may be a ship, an aircraft, or a yacht, or any other type of vehicle requiring the installation of the roll reduction device 100.

[0145] The following describes how to use this disclosure.

[0146] Usage instructions include: S1: Obtain the vehicle's sway direction. For example, if the vehicle is a yacht, the sway direction obtained is usually the length direction of the yacht, which is the roll direction.

[0147] S2: Drive the flywheel 1 to rotate around the precession axis until the rotation axis is perpendicular to the oscillation direction. For example, after the oscillation direction is determined, the flywheel 1 can be driven to rotate by the first drive 22 until the A-axis of the flywheel 1 is perpendicular to the length direction of the yacht.

[0148] S3: Using the position of the flywheel 1 after the swing adjustment as the zero point position, the flywheel 1 is driven to swing positively and negatively around the precession axis based on the zero point position to reduce the vehicle's sway.

[0149] For example, the zero point position is the position where the A axis of flywheel 1 is perpendicular to the length direction of the yacht. When in use, after the rotation axis A of flywheel 1 rotates to the zero point position, while flywheel 1 rotates through the second drive 27, it can also be driven by the first drive 22 to swing in the negative and positive directions on both sides of the zero point position, thereby reducing the roll of the yacht in the length direction.

[0150] When the roll damping device 100 needs to be installed in a long and narrow cabin, for example, a cabin located below deck with an upward-facing opening, and the opening of the cabin is long and narrow, the roll damping device 100 can be placed inside the cabin to match the opening. In this case, the length direction of the roll damping device 100 is parallel to the length direction of the cabin opening, and the width direction of the roll damping device 100 is parallel to the width direction of the cabin opening. If the rotation axis A of the flywheel 1 of the roll damping device 100 is parallel to the length direction of the ship, the flywheel 1, with this position as its zero point, will not be able to output a rotation around the ship's length. The rolling reduction torque in the direction of the ship's roll cannot reduce the maximum rolling amplitude. Since the conductive component 23 allows the flywheel 1 to rotate at a large angle around the precession axis B while simultaneously supplying power to the second drive 27, and this large angle rotation can be a 360° rotation, the first drive 22 can drive the slewing support 21 to rotate the rotation axis A of the flywheel 1 connected to the slewing support 21 to a direction perpendicular to the ship's length. With this position as the zero point and oscillating positively and negatively, the rolling reduction device 100 can smoothly output the rolling reduction torque around the ship's length, which can reduce the rolling.

[0151] It should be noted that, in this disclosure, each numerical range, except where it is explicitly stated that it does not include endpoint values, can be either endpoint values ​​or the median of each numerical range. Furthermore, the specific numerical values ​​in this disclosure are not intended to limit the corresponding size parameters in this disclosure, and all allowed values ​​are within the protection scope of this disclosure.

[0152] Although embodiments of the present disclosure have been shown and described, it will be understood by those skilled in the art that variations may be made to these embodiments without departing from the principles and spirit of the present disclosure, the scope of which is defined by the appended claims and their equivalents.
