[0019] like Figure 1 As shown, a rotor support structure for a gyro anti-roll device includes a rotor housing 1, roller bearings 2, thrust bearings 3, and a bearing pressure plate 5. The rotor housing 1 houses a gyro rotor 4. The rotor housing 1 comprises an upper housing 11 and a lower housing 12 of identical structure. The upper and lower housings 11 and 12 are fixed together to form the outer shell of the gyro rotor 4. The outer shell protects and encloses the high-speed rotating gyro rotor 4 and also serves as the mounting support for other components. The rotor housing 1 is provided with a first and second connecting bearing chambers at both ends. Specifically, the upper housing 11 includes the first and second connecting bearing chambers, while the lower housing 12 includes the first and second connecting bearing chambers. The roller bearings 2, thrust bearings 3, and bearing pressure plate 5 are arranged in sequence from the inside out and are mounted on the upper and lower ends of the gyro rotor 4. The roller bearings 2 and thrust bearings 3 are both located within the rotor housing 1, with the roller bearing 2 located within the first bearing chamber and the thrust bearing 3 located within the second bearing chamber. The bearing pressure plate 5 is fixed to the gyro rotor 4 and closely abuts the outer side of the thrust bearing 3. The rotor housing 1 provides a bearing chamber as structural support. The upper and lower roller bearings 2 are used to ensure the high-speed rotation of the gyro rotor 4 and at the same time bear the radial load of the gyro rotor 4. The thrust bearing 3 bears the axial impact load of the gyro rotor 4. That is, the two loads originally borne by the precision angular contact bearing are separated and borne by the roller bearing 2 and the thrust bearing 3. In this way, the procurement cost of the bearings, the processing cost of the parts, and the difficulty of assembly are greatly reduced, and maintenance and repair are also much more convenient.

[0020] In practice, both the roller bearing 2 and the thrust bearing 3 are mounted on the gyro rotor 4 via shoulder positioning. The gyro rotor 4 is provided with a first shoulder and a second shoulder, both located at the upper and lower ends of the gyro rotor 4. The roller bearing 2 is mounted on the first shoulder, and the thrust bearing 3 is mounted on the second shoulder. The roller bearing 2 is assembled to the gyro rotor 4 via its inner ring to ensure high-speed rotation of the gyro rotor 4 while also bearing the radial load of the gyro rotor 4. The thrust bearing 3 bears the axial impact load of the gyro rotor 4.

[0021] In practical applications, the first bearing chamber and the second bearing chamber are both circular grooves, one inside and one outside, one large and one small, and are concentrically arranged.

[0022] In practice, the bearing pressure plate 5 is fixed to the gyro rotor 4 via hexagonal bolts 6, which may be M16. The bearing pressure plate 5 is a plate structure, which may be a circular plate or a square plate, and is tightly pressed against the outside of the thrust bearing 3. The upper and lower thrust bearings 3 and the gyro rotor 4 are tightly assembled together by the upper and lower bearing pressure plates 5 and hexagonal bolts 6.

[0023] The advantages of the present invention are as follows: compared with the rotor support structure of the existing gyro anti-roll device, in which the radial load and axial impact load of the gyro rotor 4 during operation are both borne by precision angular contact bearings, resulting in excessively high procurement costs, processing costs, and assembly costs, in the rotor support structure of the present invention, the radial load of the gyro rotor 4 during operation is borne by the roller bearings 2, and the axial impact load is borne by the thrust bearings 3, thereby reducing the procurement cost of the bearings; lowering the machining accuracy requirements and assembly difficulty of the parts, thereby reducing the parts cost and assembly cost; and also providing convenience for maintenance and repair.

[0024] The above description is merely a specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any changes, combinations, or substitutions that can be easily conceived by a person skilled in the art within the technical scope disclosed in the present invention should be included in the scope of protection of the present invention. Therefore, the scope of protection of the present invention should be based on the scope of protection of the claims.
