Description

Technical Field

[0001] This utility model relates to the field of gyroscope technology, and in particular to an shaftless gyroscope rotor and its gyroscope. Background Technology

[0002] Gyroscopes are widely used in aviation, aerospace, and marine fields. The different applications of gyroscopes in various fields lead to variations in their structures, but their basic structure consists of a rotating shaft combined with a rotating wheel, which rotates at high speed under the drive of an electric motor or hydraulic motor, thereby generating a sufficiently large angular momentum.

[0003] However, this high-speed rotor has a complex structure, which places high demands on processing and assembly. High-precision bearings are usually required. In addition, the power arrangement and heat dissipation of gyroscopes using this type of rotor are not easy to solve. Utility Model Content

[0004] In view of the above-mentioned shortcomings of current gyroscope rotors, this utility model provides an shaftless gyroscope rotor and gyroscope, which omits the structure of the rotating shaft, thus facilitating the arrangement of the gyroscope's heat dissipation structure and power structure.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] According to a first aspect of the present invention, an shaftless gyroscope rotor is provided, comprising:

[0007] The outer shell is formed by connecting a first shell and a second shell;

[0008] A shaftless rotating wheel is disposed inside the housing;

[0009] A magnetic levitation bearing is installed between the end face of the shaftless rotating wheel and the outer shell to support the contactless high-speed rotation of the shaftless rotating wheel.

[0010] An external rotor motor includes an external rotor and an inner stator. The external rotor is fixed to the shaftless rotating wheel, and the inner stator is fixed to the second housing, for driving the shaftless rotating wheel to rotate.

[0011] Optionally, the magnetic levitation bearings are symmetrically distributed on both ends of the shaftless rotating wheel.

[0012] Optionally, the magnetic levitation bearing is a non-contact electromagnetic bearing.

[0013] Optionally, a heat dissipation channel is provided between the first housing and the second housing.

[0014] Optionally, the outer casing is formed by fastening the first casing and the second casing together with bolts to form a closed cavity.

[0015] Optionally, the first housing and the second housing are connected by at least three evenly distributed bolts.

[0016] Optionally, the motor inner stator is fixed to the inside of the second housing by screws.

[0017] Optionally, the magnetic levitation bearing is larger than the bearing size of a gyroscope rotor of the same specifications.

[0018] Optionally, the outer rotor of the motor is connected to the shaftless rotating wheel by an interference fit or screws.

[0019] According to a second aspect of the present invention, a gyroscope is provided, comprising the aforementioned shaftless gyroscope rotor.

[0020] The advantages of this invention are as follows: Firstly, the traditional rotating shaft is omitted, and an external rotor motor is used, which greatly simplifies the structure of the gyroscope rotor and makes it easier to arrange the heat dissipation and power structures of the gyroscope. Secondly, it can significantly reduce the assembly difficulty of the gyroscope rotor and improve the economic efficiency of manufacturing the gyroscope rotor. Finally, a magnetic levitation bearing is used on the end face of the rotating wheel, which greatly reduces the energy consumption of the gyroscope operation compared with traditional bearings.

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] Example 1:

[0026] like Figure 1 As shown, an shaftless gyroscope rotor includes: a housing, formed by connecting a first housing 1 and a second housing 3; a shaftless rotating wheel 4 disposed inside the housing; a magnetic levitation bearing 5 installed between the end face of the shaftless rotating wheel 4 and the housing, for supporting the contactless high-speed rotation of the shaftless rotating wheel 4; and an external rotor motor, including an external rotor 7 and an internal stator 8, wherein the external rotor 7 is fixed to the shaftless rotating wheel 4 and the internal stator 8 is fixed to the second housing 3, for driving the shaftless rotating wheel 4 to rotate.

[0027] Specifically, the outer shell consists of a first housing 1 and a second housing 3 connected by bolts 2 to form a closed cavity. Inside, a shaftless rotating wheel 4 achieves contactless high-speed rotation via magnetic levitation bearings 5 ​​on its end face. The outer rotor 7 of the external rotor motor is fixed to the rotating wheel, and the inner stator 8 is fixed to the second housing 3. The rotating wheel is driven to rotate via electromagnetic action, generating angular momentum. This eliminates the need for a traditional rotating shaft, simplifying the structure and reducing processing and assembly difficulty. The magnetic levitation bearings 5 ​​are frictionless, have low energy consumption, and a long lifespan. The external rotor motor directly drives the rotating wheel, resulting in efficient power transmission and easy-to-arrange heat dissipation.

[0028] Example 2:

[0029] like Figure 1 As shown, an shaftless gyroscope rotor includes: a housing, formed by connecting a first housing 1 and a second housing 3; a shaftless rotating wheel 4 disposed inside the housing; a magnetic levitation bearing 5 installed between the end face of the shaftless rotating wheel 4 and the housing, for supporting the contactless high-speed rotation of the shaftless rotating wheel 4; and an external rotor motor, including an external rotor 7 and an internal stator 8, wherein the external rotor 7 is fixed to the shaftless rotating wheel 4 and the internal stator 8 is fixed to the second housing 3, for driving the shaftless rotating wheel 4 to rotate.

[0030] Specifically, the outer shell consists of a first housing 1 and a second housing 3 connected by bolts 2 to form a closed cavity. Inside, a shaftless rotating wheel 4 achieves contactless high-speed rotation via magnetic levitation bearings 5 ​​on its end face. The outer rotor 7 of the external rotor motor is fixed to the rotating wheel, and the inner stator 8 is fixed to the second housing 3. The rotating wheel is driven to rotate via electromagnetic action, generating angular momentum. This eliminates the need for a traditional rotating shaft, simplifying the structure and reducing processing and assembly difficulty. The magnetic levitation bearings 5 ​​are frictionless, have low energy consumption, and a long lifespan. The external rotor motor directly drives the rotating wheel, resulting in efficient power transmission and easy-to-arrange heat dissipation.

[0031] Furthermore, the magnetic levitation bearings 5 ​​are symmetrically distributed on both ends of the shaftless rotating wheel 4. The symmetrical installation of the magnetic levitation bearings 5 ​​on both ends of the rotating wheel allows them to balance the weight and centrifugal force of the rotating wheel through electromagnetic force. This symmetrical distribution enhances rotational stability, reduces vibration and sway, and improves the overall load-bearing capacity and reliability of the bearings.

[0032] Furthermore, the magnetic levitation bearing 5 is a non-contact electromagnetic bearing. It utilizes an electromagnetic field to generate levitation force, eliminating physical contact between the rotating wheel and the outer shell. This completely eliminates mechanical friction, reduces energy consumption and heat generation. Because there is no physical contact, there is no wear on components, resulting in low maintenance costs and suitability for long-term high-speed operation.

[0033] Furthermore, a heat dissipation channel is provided between the first housing 1 and the second housing. Airflow or cooling medium is guided through the heat dissipation channel between the housings to remove the heat generated by the motor and bearings, preventing overheating of the components.

[0034] Furthermore, the outer shell is formed by fastening the first housing 1 and the second housing 3 together with bolts 2 to form a closed cavity. The bolt connection structure is robust, has strong vibration resistance, and facilitates disassembly and maintenance of internal components.

[0035] Furthermore, the first housing 1 and the second housing 3 are connected by at least three evenly distributed bolts 2. This ensures a secure connection and uniform load distribution.

[0036] Furthermore, the inner stator 8 of the motor is fixed to the inner side of the second housing 3 by screws 6. The screws 6 firmly fix the inner stator 8 of the motor to the inner side of the second housing 3, ensuring a stable connection between the inner stator 8 and the housing, preventing displacement of the inner stator 8, and ensuring the accuracy of the drive.

[0037] Furthermore, the magnetic levitation bearing 5 is larger than the bearing size of a gyroscope rotor of the same specifications. By increasing the size of the magnetic levitation bearing 5, the electromagnetic interaction area is expanded, enhancing the levitation force and load-bearing capacity, making it suitable for high-power or high-speed applications.

[0038] Furthermore, the outer rotor 7 of the motor and the shaftless rotating wheel 4 are connected by an interference fit or screws. The interference fit or screw connection ensures that the outer rotor 7 of the motor and the rotating wheel rotate synchronously, ensuring reliable connection and high torque transmission efficiency.

[0039] Example 3:

[0040] This embodiment provides a gyroscope comprising the aforementioned shaftless gyroscope rotor. The shaftless design results in a compact and lightweight overall structure, and offers advantages such as low overall energy consumption, excellent heat dissipation, and low maintenance costs, making it suitable for precision applications in aviation, aerospace, and marine fields.

[0041] The above description is merely a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the protection scope of the claims.
