Description

Technical Field

[0001] The present invention relates to the technical field of anti-rolling, and particularly to an anti-rolling gyro rotor structure that can be quickly transformed. Background Art

[0002] An anti-rolling gyro device is an anti-rolling equipment applied on ships. It mainly provides angular momentum by a high-speed rotating gyro rotor, and uses the precession angular velocity caused by the rolling of the ship to generate a rolling moment acting on the ship, having a good anti-rolling effect on the ship.

[0003] The rotor system of the anti-rolling gyro device reaches the specified angular momentum through its own high-speed rotation. When the ship rolls, the rotor system generates precession, thereby providing an anti-rolling moment for the ship. One of the indicators for measuring the working ability of the anti-rolling gyro is the angular momentum. At a certain rotational speed, the angular momentum is proportional to the moment of inertia of the rotor system. With the continuous improvement of the application requirements of the anti-rolling gyro device, the specifications of the anti-rolling gyro device are constantly increasing, and different required moments of inertia and rotor sizes follow. Traditional gyro rotor design schemes have many disadvantages:

[0004] 1. Traditional gyro rotor design forms often adopt an integrated design form, that is, the rotor spoke and the rotor shaft are designed as a whole. The design size of the rotor is large, but the difference between the journal diameter of the rotor shaft and the diameter of the rotor spoke is large, and the cutting amount of machining increases accordingly, and a contradiction is formed between the machining stress and the machining cycle;

[0005] 2. Traditional gyro rotors adopt an integrated design form. Since they cannot be disassembled, once the machining of the journal position exceeds the tolerance, it is very likely that the entire rotor will be scrapped directly, resulting in a large economic loss;

[0006] 3. Traditional gyro rotors also adopt the form of replaceable rotor spokes, and the rotating shaft adopts an integrated design. Due to the integrated design of the rotating shaft, the size of the blank material of the rotating shaft is large and not conducive to machining. In addition, the integrated design of the rotating shaft is not conducive to adapting to changes in the bearing span, motor selection, etc., which cause changes in the journal and shaft length of the rotating shaft.

[0007] 4. Due to the large moment of inertia of the traditional gyro rotor, it is difficult to increase the rotational speed of the gyro rotor to the working speed in a short time by using a single-motor drive mode, and a large working preparation time needs to be reserved. Summary of the Invention

[0008] In view of the deficiencies existing in the above-mentioned prior art, the present invention provides a roll reduction gyro rotor structure that can be quickly transformed.

[0014] Further, the rotor spoke includes a spoke plate, and the assembly hole is located at the center of the spoke plate; the assembly hole has an annular column symmetrically extending upward and downward from the upper and lower end faces of the spoke plate; the outer edge of the spoke plate has an arc-shaped edge symmetrically extending upward and downward, and the arc-shaped edge and the annular column form the upper and lower arc-shaped grooves on the upper and lower end faces of the spoke plate.

[0015] Further, the assembly holes are composed of upper assembly holes and lower assembly holes which are arranged at intervals, and the upper assembly holes and the lower assembly holes are coaxial with the rotor spoke; the upper half shaft and the lower half shaft are respectively assembled into the upper assembly hole and the lower assembly hole in an interference fit manner; the circumferences of the upper half shaft and the lower half shaft respectively have connecting parts, and the upper half shaft and the lower half shaft are respectively bolted to the upper and lower end faces of the rotor spoke through the connecting parts.

[0016] Further, the assembly holes are through holes that penetrate through the upper and lower parts of the center of the rotor spoke, and the mating shaft sections of the upper half shaft and the lower half shaft are respectively assembled at the upper and lower ends of the through hole in an interference fit manner.

[0017] Further, the outer edge of the rotor spoke is higher than the positions of the shaft sections of the upper half shaft and the lower half shaft where the motor is installed.

[0018] Further, the upper half shaft and the lower half shaft are respectively inserted into the assembly holes in an interference fit manner to achieve fixed connection with the centers of the upper and lower end faces of the rotor spoke.

[0019] Further, at the centers of the upper and lower end faces of the rotor spoke, the upper half shaft and the lower half shaft are respectively placed into the assembly holes of the rotor spoke in a small clearance fit manner, and at the same time, the connecting parts of the upper half shaft and the lower half shaft are respectively bolted to the upper and lower end faces of the rotor spoke.

[0021] Further, the connecting parts of the upper half shaft and the lower half shaft are welded to the rotor spoke.

[0022] Advantages of the present invention:

[0023] The quickly transformable anti-rolling gyro rotor structure of the present invention uses a detachable rotor structure to replace the traditional integral design of the gyro rotor, realizes the modular design and modular manufacturing of the anti-rolling gyro rotor structure, can quickly change the length of the rotor, the moment of inertia of the rotor spoke, etc. according to requirements, effectively reduces the processing cycle of the anti-rolling gyro rotor structure, effectively improves the design and production efficiency, and reduces the production cost.

[0024] The present invention is driven by two driving motors, and the control module uses electric control logic to control the start and shutdown of the two driving motors, realizing quick start and low running power consumption.

[0025] The present invention replaces the integrated design of the traditional gyro rotor with a combined structure of a rotor spoke, an upper half shaft, and a lower half shaft. The amount of machining is small, the contradiction between machining stress and machining cycle is small, and the blank materials of the three parts of the rotor spoke, the upper half shaft, and the lower half shaft can be mass-produced to complete rough machining or even finish machining, effectively reducing the requirements for production and processing tools. In addition, the present invention has machining fault tolerance. During the machining process, if problems such as out-of-tolerance of the machined part size or other machining non-conformities occur, only the corresponding parts need to be scrapped, without directly scrapping the entire anti-rolling gyro rotor structure, effectively reducing economic losses and machining cycle losses. In addition, the rotor spoke can adopt a lightweight design. At the same time, due to the separated structural form of the upper half shaft and the lower half shaft, a hollow area that does not affect strength and moment of inertia can be added in the middle of the anti-rolling gyro rotor structure, effectively reducing the weight of the anti-rolling gyro rotor structure and enhancing the competitiveness of the product.

[0026] The present invention can quickly replace the corresponding rotor spoke, upper half shaft, and lower half shaft according to the design task requirements of the anti-rolling gyro device, and quickly change the structural dimensions and moment of inertia of the anti-rolling gyro rotor structure. While meeting the research and development of multi-specification anti-rolling gyro devices, it does not increase the preparation production cycle of parts.

[0027] When the upper half shaft and the lower half shaft of the present invention adopt an interference fit assembly form with the rotor spoke, the assembly process is simple and clear, the process flow is single, avoiding cumbersome assembly process flows, and effectively ensuring the efficiency of torque transmission between the assembled bodies, that is, the rotor spoke, the upper half shaft, and the lower half shaft, and ensuring the efficiency of motor power output.

[0028] The rotor spoke of the present invention forms a strong solid connection at the positions where it is installed with the upper half shaft and the lower half shaft through reasonably designed upper arc grooves and lower arc grooves, and forms a large-mass torque formation part at the outer edge of the rotor spoke. The arc grooves reduce the mass inside, while meeting the use reliability of the rotor spoke, can effectively reduce the weight of the anti-rolling gyro rotor structure, and is beneficial to reducing processing costs.

[0029] When the outer edge of the rotor spoke is higher than the shaft sections of the upper half shaft and the lower half shaft where the motor is installed, the size of the anti-rolling gyro can be effectively reduced. It utilizes the structural space of the rotor spoke without increasing the processing difficulty of the anti-rolling gyro, and effectively increases the energy-mass ratio of the gyro rotor and reduces the flywheel mass.

[0030] The rotor spoke, the upper half shaft, and the lower half shaft of the present invention can all use existing conventional and mature material products suitable for ship navigation, which is beneficial to cost control and production preparation cycle control. Description of the Drawings

[0043] Embodiment 1

[0044] This embodiment describes a roll stabilization gyro rotor structure that can be quickly transformed. It is a detachable structure composed of multiple parts and can be selected and matched according to design requirements to achieve modular design and manufacturing, thereby improving design and production efficiency.

[0045] As Figure 1 shown, the roll stabilization gyro rotor structure includes a rotor spoke 1, an upper half shaft 2, and a lower half shaft 3. The upper half shaft 2 and the lower half shaft 3 are coaxially installed in the assembly holes at the center of the rotor spoke 1. The driving motors A and B are respectively connected to the upper half shaft 2 and the lower half shaft 3 to drive the upper half shaft 2 and the lower half shaft 3 to rotate respectively. At the same time, the driving motors A and B are respectively connected to the control module. The roll stabilization gyro rotor structure controls the start, stop, and rotation speed of the driving motors A and B through the control module. In this embodiment, the driving motors A and B can be respectively installed on the support structure of the roll stabilization gyro rotor structure. The driving motors A and B in this embodiment can adopt ring motors, inner rotor motors, etc. For example, the ring motor is sleeved on the upper half shaft 2 and the lower half shaft 3 through the inner ring, and the outer ring is fixedly connected to the support structure of the roll stabilization gyro rotor structure. The rotor of the inner rotor motor is sleeved on the upper half shaft 2 and the lower half shaft 3, and the stator is fixedly connected to the support structure of the roll stabilization gyro rotor structure.

[0046] During the start-up and acceleration phase, the anti-rolling gyro rotor structure is driven to rotate synchronously by drive motor A and drive motor B to generate precession, providing an anti-rolling moment for the ship. After quickly reaching the operating speed, drive motor A or drive motor B is turned off, and the driving power of one drive motor and the rotational inertia of the rotor spokes are used to maintain the operating speed. This can enable the anti-rolling gyro rotor structure to effectively reduce the power consumption of the product while ensuring the acceleration time. In this embodiment, the drive motor that is turned off first is used to quickly start the anti-rolling gyro rotor structure and is the acceleration motor, and the drive motor that keeps running is the main motor. The acceleration motor can be drive motor A or drive motor B, and can be preset as drive motor A or drive motor B, or drive motor A or drive motor B can be rotated during multiple uses to avoid long-term wear at fixed positions, which is beneficial to extending the service life of the anti-rolling gyro rotor structure.

[0047] In addition, in this embodiment, a speed sensor is installed at the end of the upper half shaft 2 or the lower half shaft 3. The speed sensor is used to monitor the speed of the anti-rolling gyro rotor structure in real time and feed the speed back to the control module. When the received speed reaches the threshold, the control module controls drive motor A or drive motor B to turn off.

[0048] When the anti-rolling gyro rotor structure needs to be redesigned or optimized, such as when the span of one or two bearings changes or the motor model selection changes, etc., the corresponding parts among the three parts can be disassembled and replaced with the corresponding parts that meet the new design or optimized structure, and quickly assembled into the redesigned or optimized anti-rolling gyro rotor structure.

[0049] The assembly hole of the rotor spoke 1 is located at the center of the spoke plate. The assembly hole has an annular column that symmetrically extends upward and downward from the upper and lower end faces of the spoke plate. The annular column is the support structure for the upper half shaft 2 and the lower half shaft 3 and the connection structure with the rotor spoke 1. The outer edge of the spoke plate has an arc-shaped edge that symmetrically extends upward and downward. The arc-shaped edge and the annular column form an upper arc-shaped groove and a lower arc-shaped groove surrounding the assembly hole on the upper and lower end faces of the spoke plate. The upper arc-shaped groove and the lower arc-shaped groove increase the moment of momentum and effectively reduce the weight of the overall structure of the anti-rolling gyro rotor while ensuring the stable connection between the upper half shaft 2 and the lower half shaft 3 and the rotor spoke 1 and increasing the weight of the spoke plate edge. Under the condition that the anti-rolling gyro device generates precession and bears the anti-rolling moment, the design of the upper arc-shaped groove and the lower arc-shaped groove of the rotor spoke 1 needs to meet the requirement that the stress it bears is not greater than the allowable stress of the material for making the rotor spoke 1, and the safety factor is generally taken as 1.2 - 2.

[0050] In addition, the centrifugal deformation of the rotor spoke 1 at the design speed should also be calculated. To avoid rubbing against other structural components of the anti-rolling gyro device, it is generally required that the centrifugal deformation is not greater than 2 mm. Additionally, coaxial counterbores can be respectively provided at the lower part of the upper half shaft 2 and the upper part of the lower half shaft 3, forming hollow regions in the middle of the upper half shaft 2 and the lower half shaft 3 that do not affect the shaft strength and moment of inertia, further effectively reducing the weight of the anti-rolling gyro rotor structure, reducing the required motor power, and thus facilitating the reduction of the production cost of the anti-rolling gyro rotor structure.

[0051] Preferably, as Figure 2 shown, in this embodiment, the rotor spoke 1 is the first rotor spoke 101, and its assembly holes are composed of upper assembly holes and lower assembly holes arranged at intervals, and the upper assembly holes and the lower assembly holes are coaxial with the first rotor spoke 101. The upper half shaft 2 and the lower half shaft 3 are respectively the first upper half shaft 201 and the first lower half shaft 301. The lower part of the first upper half shaft 201 and the upper part of the first lower half shaft 301 respectively have connecting parts on the circumferential direction, and a plurality of through holes are arranged at intervals on the connecting parts. A plurality of threaded holes corresponding to the through holes are respectively arranged around the upper assembly holes and the lower assembly holes on the upper and lower end faces of the rotor spoke 1. After the mating shaft sections of the lower part of the first upper half shaft 201 and the upper part of the first lower half shaft 301 are respectively assembled into the upper assembly holes and the lower assembly holes in an interference fit manner, the connecting parts of the first upper half shaft 201 and the first lower half shaft 301 are connected by bolts in a threaded connection manner to enhance the reliability of the connection. In this embodiment, through interference fit and bolt connection, the assembly of the first rotor spoke 101, the first upper half shaft 201, and the first lower half shaft 301 can be quickly completed, forming an anti-rolling gyro rotor structure that meets the design requirements.

[0052] The first driving motor A401 is connected to the first upper half shaft 201 in an interference manner through a motor shaft, and the first driving motor B601 is connected to the first lower half shaft 301 in an interference manner through a motor shaft. A first speed sensor 501 is installed at the end of the first lower half shaft 301. As Figure 3 shown, during the start-up and acceleration stage of the anti-rolling gyro device, the first driving motor A401 and the first driving motor B601 are synchronously started under the control of the control module to drive the anti-rolling gyro rotor structure to rotate together. The first speed sensor 501 real-time collects the rotor speed and feeds the rotor speed back to the control module. When the control module determines that the real-time rotor speed is greater than 70% of the rated speed (or other thresholds set according to the working conditions), the control module controls the first driving motor A401 or the first driving motor B601 to shut down, and the first driving motor B601 or the first driving motor A401 keeps running.

[0053] The production method of this rotor structure can be:

[0054] The three parts of the rotor spoke 1, the upper half shaft 2, and the lower half shaft 3 are respectively rough machined. After the three parts are assembled, finish machining is carried out according to the design requirements to form the designed anti-rolling gyro rotor structure.

[0055] Alternatively, after the three parts of the rotor spoke 1, the upper half shaft 2, and the lower half shaft 3 only undergo conventional rough machining and finish machining, they are directly assembled into a usable gyro rotor structure according to the design requirements. The interference fit assembly form effectively ensures the coaxiality and stable rotation of the rotor spoke 1, the upper half shaft 2, and the lower half shaft 3. The design of the threaded holes further enhances the stability of power transmission. In this production method, the rough machining blank parts of the rotor spoke 1, the upper half shaft 2, and the lower half shaft 3 can be respectively designed into a general shape and size form and mass-produced by forging to improve the production efficiency of the anti-rolling gyro rotor structure and reduce the production cost. At the same time, the rotor spoke 1, the upper half shaft 2, and the lower half shaft 3 can be batch processed into series parts according to various moments of inertia and various lengths. According to the design task requirements, the rotor spoke 1 with a moment of inertia meeting the requirements, the upper half shaft 2 and the lower half shaft 3 with lengths and strengths satisfying the bearing span, the motor selection dimensions, and the layout positions are assembled into the designed anti-rolling gyro rotor structure.

[0056] All parts of the anti-rolling gyro rotor structure adopt existing materials that meet the requirements of the ship navigation environment.

[0057] Embodiment 2

[0058] This embodiment discloses a quickly transformable anti-rolling gyro rotor structure, which is similar in structure to the quickly transformable anti-rolling gyro rotor structure of Embodiment 1. The drive scheme is the same as that of Embodiment 1. The rotor spoke 1 is the second rotor spoke 102, and the upper half shaft 2 and the lower half shaft 3 are respectively the second upper half shaft 202 and the second lower half shaft 302, as Figure 4 shown. The difference is that the assembly hole in the center of the second rotor spoke 102 is a through hole that penetrates up and down. The mating shaft sections of the second upper half shaft 202 and the second lower half shaft 302 are respectively assembled at the upper and lower ends of the through hole of the second rotor spoke 102 by interference fit and fixed with bolts. Machining a through hole in the center of the second rotor spoke 102 is more convenient than machining the upper and lower assembly holes in Embodiment 1, and can better ensure the coaxiality of the second upper half shaft 202 and the second lower half shaft 302, and is also convenient for optimizing the structure and dimensions of the mating shaft sections of the second upper half shaft 202 and the second lower half shaft 302 with the assembly hole at any time.

[0059] Embodiment 3

[0060] This embodiment discloses a roll reduction gyro rotor structure that can be quickly transformed.

The rotor spoke 1 is the third rotor spoke 103, and the upper half shaft 2 and the lower half shaft 3 are the third upper half shaft 203 and the third lower half shaft 303 respectively. As Figure 5 shown, the difference is that the outer edge of the third rotor spoke 103 is higher than the shaft sections of the motors installed on the third upper half shaft 203 and the third lower half shaft 303. The drive motor A and the drive motor B are installed within the space occupied by the rotor spoke. The outer edge space at the motor shaft end can be effectively utilized for other purposes. Additionally, the increased outer edge of the rotor spoke increases the rotor weight at the maximum turning radius of the third rotor spoke 103, greatly enhancing the moment of inertia of the gyro rotor, thereby increasing the angular momentum, effectively increasing the energy-mass ratio of the gyro rotor, reducing the flywheel mass, and further reducing the size of the roll reduction gyro.

[0061] Embodiment 4

[0062] This embodiment discloses a roll reduction gyro rotor structure that can be quickly transformed. It is similar in structure to the roll reduction gyro rotor structure of the above embodiment, and the drive scheme is the same as that of Embodiment 1. The rotor spoke 1 is the fourth rotor spoke 104, and the upper half shaft 2 and the lower half shaft 3 are the fourth upper half shaft 204 and the fourth lower half shaft 304 respectively. As Figure 6 shown, the difference is that the fourth upper half shaft 204 and the fourth lower half shaft 304 are only connected to the fourth rotor spoke 104 in an interference fit manner to meet certain task requirements, such as in the case of an ultra-small roll reduction gyro device designed for a small ship, where the roll reduction torque requirement is relatively small, but there is not enough space to arrange screws due to the shape and size requirements.

[0063] Embodiment 5

[0064] This embodiment discloses a roll reduction gyro rotor structure that can be quickly transformed. It is similar in structure to the roll reduction gyro rotor structure of the above embodiment, and the drive scheme is the same as that of Embodiment 1. The rotor spoke 1 is the fifth rotor spoke 105, and the upper half shaft 2 and the lower half shaft 3 are the fifth upper half shaft 205 and the fifth lower half shaft 305 respectively. As Figure 7As shown in the figure, the difference lies in that the fifth upper half shaft 205 and the fifth lower half shaft 305 are assembled in the assembly holes of the fifth rotor spoke 105 in the form of a small clearance fit and are connected and fixed to the fifth rotor spoke 105 by bolts. In this embodiment, the mating shaft sections of the fifth upper half shaft 205 and the fifth lower half shaft 305 can be easily assembled into the assembly holes, and the connection strength with the fifth rotor spoke 105 is ensured by bolt connection. It can be applied to various spindle integrated design anti-rolling gyro rotor structure schemes such as using sliding bearings, adopting circulating liquid cooling spindles, oil-gas lubrication, and circulating oil lubrication, which is convenient for the disassembly and assembly of sliding bearings in the later stage, as well as the maintenance, repair, and replacement of spindle integrated designs such as the spindle circulating cooling system, oil-gas lubrication, and circulating oil lubrication.

[0065] Embodiment Six

[0066] This embodiment discloses a quickly transformable anti-rolling gyro rotor structure, which is similar in structure to the quickly transformable anti-rolling gyro rotor structure of the above embodiment. The driving scheme is the same as that of Embodiment One. The rotor spoke 1 is the sixth rotor spoke 106, and the upper half shaft 2 and the lower half shaft 3 are respectively the sixth upper half shaft 206 and the sixth lower half shaft 306. As Figure 8 shown in the figure, the difference lies in that the lower part of the sixth upper half shaft 206 and the upper part of the sixth lower half shaft 306 respectively have external threads on the mating shaft sections with the sixth rotor spoke 106, and the assembly holes of the sixth rotor spoke 106 have internal threads matching the external threads. The sixth upper half shaft 206 and the sixth lower half shaft 306 are respectively threadedly connected to the sixth rotor spoke 106 to ensure the coaxial assembly requirements among the upper half shaft 206, the lower half shaft 306, and the rotor spoke 106. For the reliability of power transmission, the connection parts of the sixth upper half shaft 206 and the sixth lower half shaft 306 can also be welded to the sixth rotor spoke 106 simultaneously.

[0067] Although the principle of the present invention has been described in detail above in conjunction with the preferred embodiments of the present invention, those skilled in the art should understand that the above embodiments are only explanations of the illustrative implementation modes of the present invention and do not limit the scope of the present invention.
