[0021] 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.
[0022] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments.
[0023] Reference Figures 1 to 4 This utility model discloses an adjustable torque anti-collision device for a wind power robot camera gimbal, comprising a housing 1, a drive assembly inside the housing 1, a rotating shaft 2 connected to the drive assembly, and a front-end mechanism and an adjustment assembly for adjusting the torque at both ends of the rotating shaft 2 extending outside the housing 1, respectively; the drive assembly includes a first gear 3, which meshes with a second gear 4, and the second gear 4 is connected to a power unit; one end of the first gear 3 is connected to the rotating shaft 2, and the other end of the first gear 3 is connected to a drive shaft 16; the adjustment assembly includes a retaining ring 17 sleeved on the drive shaft 16, and multiple O-rings 7 are provided between the retaining ring 17 and the drive shaft 16, with the O-rings 7 sleeved on the drive shaft 16.
[0024] The front-end mechanism includes a first rotating shaft front end 8 and a second rotating shaft front end 9. The first rotating shaft front end 8 and the second rotating shaft front end 9 enter the field and collide with the obstacle, and transmit the collision force to the rotating shaft 2 through the first rotating shaft front end 8 and the second rotating shaft front end 9.
[0025] This invention increases friction by using O-rings 7, thereby changing the magnitude of the torque that can be transmitted between the drive shaft 16 and the rotating shaft 2. Under normal working conditions, it can prevent damage when the external force exceeds the range that the planetary reducer 15 can withstand.
[0026] In a further optimized design, the power unit includes a drive motor 5, which is connected to the second gear 4 via a planetary reducer 15. The rotational torque output by the drive motor 5 drives the second gear 4 to rotate through the planetary reducer 15, and the second gear 4 transmits the torque.
[0027] In a further optimized design, the end of the housing 1 furthest from the front-end mechanism is connected to the planetary reducer 15 via a fixed bracket 6. This allows the rotational torque output by the drive motor 5 to drive the second gear 4 through the planetary reducer 15.
[0028] The drive motor 5 is connected to the fixed bracket 6 through the connecting frame, so that the drive motor 5 can output rotational torque stably.
[0029] The design is further optimized so that the outer diameter of the first gear 3 is larger than that of the second gear 4. The rotational speed of the second gear 4 is greater than that of the first gear 3, enabling the second gear 4 to effectively drive the first gear 3 to rotate.
[0030] In a further optimized design, the retaining ring 17 has an opening, and connecting plates are fixedly connected to both ends of the opening of the retaining ring 17. Each of the two connecting plates has a through hole, and the two through holes are connected by a connecting part.
[0031] The inner diameter of the retaining ring 17 can be effectively changed through the opening on the retaining ring 17.
[0032] In a further optimized design, the connecting part includes an adjusting torque screw 11. The adjusting torque screw 11 passes through two through holes and has an adjusting torque nut 12 threadedly connected to one end extending out of the through holes. By screwing the adjusting torque screw 11 into the adjusting torque nut 12, the inner diameter of the retaining ring 17 can be adjusted.
[0033] In a further optimized design, an adjusting torque spring 10 is fitted onto the end of the adjusting torque screw 11 near the nut of the adjusting torque screw 11. The compression ratio of the adjusting torque spring 10 can be adjusted by screwing the adjusting torque screw 11 into the adjusting torque nut 12.
[0034] In a further optimized design, the retaining ring 17 is fixedly connected to the first gear 3 on the side opposite to the opening. This prevents the retaining ring 17 from rotating with the drive shaft 16 and increases friction through the O-ring 7.
[0035] In order to enable the rotating shaft 2 to rotate stably within the housing 1, multiple rotating shaft support bearings 13 are fitted on the rotating shaft 2 to fix the position of the rotating shaft 2 and enable it to rotate stably.
[0036] In order to enable the drive shaft 16 to rotate stably within the housing 1, multiple drive shaft support bearings 14 are fitted on the drive shaft 16 to fix the position of the drive shaft 16 and enable it to rotate stably.
[0037] Working process: After the entire system is powered on, the drive motor 5 starts to rotate, driving the second gear 4 to rotate. The second gear 4 drives the first gear 3 to rotate, and the first gear 3 drives the rotating shaft 2 and the transmission shaft 16 to rotate. The transmission shaft 16 provides friction through the O-ring 7, transmitting the rotational torque to the rotating shaft 2. The rotating shaft 2 drives the front-end mechanism mounted at its front end to rotate.
[0038] By changing the length of the adjusting torque screw 11 screwed into the adjusting torque nut 12 and compressing the length of the adjusting torque spring 10, the size of the opening on the retaining ring 17 is changed, thereby changing the magnitude of the elastic deformation of the O-ring 7, changing the magnitude of the friction force, and thus changing the magnitude of the torque that can be transmitted between the drive shaft 16 and the rotating shaft 2.
[0039] This invention transmits torque through the elastic deformation of the O-ring 7; and changes the magnitude of the transmitted torque by adjusting the torque spring 10; when encountering an external force that reverses the output, the relative sliding between the O-ring 7 and the rotating shaft 2 and the transmission shaft 16 protects the rear torque output mechanism.
[0040] Meanwhile, when encountering reverse output of external force, the deformation of O-ring 7 changes, and the adjusting torque spring 10 can compress and release space to reduce friction, thereby better protecting the rear torque output mechanism.
