Description

Technical Field

[0001] This utility model specifically relates to the field of gear bearing technology, and specifically to a gear bearing. Background Technology

[0002] In drones, gear bearings are mainly used in transmission components such as gearboxes; they act like a "stabilizer," allowing rotating components such as gears to rotate smoothly, reducing friction and wear, and ensuring effective power transmission. For example, in the power transmission system of a drone, gear bearings enable the motor's power to be transmitted efficiently and stably to components such as propellers, allowing the drone to fly normally. Traditional UAV gear bearings may have inadequate sealing structures, easily leading to lubricant leakage, insufficient bearing lubrication, accelerated wear, and shortened service life. Furthermore, selecting appropriate lubrication methods and lubricants for different speed requirements is challenging; low viscosity makes it difficult for low-speed shaft bearings to form an oil film, while high viscosity causes high-speed shafts to overheat. During UAV flight, gear bearings continuously bear loads, and prolonged operation can lead to wear and fatigue cracks on the gear surfaces. This not only affects gear transmission efficiency but may also generate abnormal noise and even impact the stability of UAV flight. As drones become lighter and more multifunctional, traditional bearings may not be able to meet these new requirements in terms of structure and materials. For example, some traditional metal bearings are heavy, which is not conducive to the lightweight design of drones. Traditional bearings also have shortcomings in integrating multiple functions. Utility Model Content

[0003] The purpose of this utility model is to provide a gear bearing. In this device, the gear is effectively fitted and installed with the outer ring of the bearing through a mounting ring and a mating ring. The fixed installation between the elastic plate and the arc plate effectively ensures the synchronous rotation of the bearing and the gear during use, effectively realizing the transmission of rotation from the gear to the rotating blades of the UAV. The interference fit effectively reduces the noise generated by the gear bearing during rotation, thereby solving the problems mentioned above in the background art.

[0004] To achieve the above objectives, this utility model provides the following technical solution: A gear bearing includes a gear; multiple arc-shaped plates are integrally formed on the inner side of the gear; the inner side of the gear is interference-fitted with a mounting ring; multiple notches are formed on the mounting ring, and the notches cooperate with elastic plates provided on the mating ring. The inner surface of the elastic plate is fixedly installed on the outer surface of the arc-shaped plate; As a further technical solution of this utility model, a support platform is also provided on the inner side of the mounting ring; the support platform is fitted and installed in close contact with the bottom of the boss on the top of the mating ring. As a further technical solution of this utility model, multiple elastic plates are provided, and adjacent elastic plates are set at 90°; the elastic plates are integrally set on the mating ring surface at the bottom of the boss. As a further technical solution of this utility model, the multiple arc-shaped plates arranged on the inner side of the gear are all located between two adjacent elastic plates, wherein at least two arc-shaped plates are arranged between two adjacent elastic plates. As a further technical solution of this utility model, the inner wall of the mating ring is installed with an interference fit to the outer ring; a retainer is provided inside the outer ring; and multiple rectangular grooves are provided on the retainer to facilitate the installation of needle rollers. As a further technical solution of this utility model, the inner wall of the outer ring is provided with a limiting groove corresponding to the position of the needle roller, and the two sides of the limiting groove are respectively a sloping groove with an inclined angle and an arc-shaped groove. The limiting groove is composed of the arc-shaped groove and the sloping groove.

[0005] Compared with the prior art, the beneficial effects of this utility model are: In this invention, the needle rollers are installed in the rectangular grooves on the cage during use, and the surface of the needle rollers is made to fit against the inner wall of the outer ring, effectively achieving contact and ensuring that the structure installed inside the cage can rotate freely. In this utility model, a mating ring is installed on the surface of the outer ring. An elastic plate integrally set on the side wall of the mating ring is effectively fixed to the surface of the arc plate on the inner side of the gear, effectively ensuring the mating efficiency of the gear as a whole and the bearing as a whole. In this invention, the notch on the mounting ring is located at the bottom of the elastic plate, which effectively prevents the side wall of the mounting ring from blocking the elastic plate. At the same time, it also ensures the synchronous rotation of the gear and the bearing. The support platform on the inner side of the mounting ring effectively contacts the bottom of the boss, realizing the overall support effect of the mounting ring on the mating ring. This prevents the mating ring and the outer ring from shifting during use, thereby ensuring the working efficiency of the gear and bearing. In this invention, the needle roller is located inside the limiting groove. When rotating in the forward direction, the needle roller rotates inside the arc-shaped groove, allowing it to rotate normally. When rotating in the reverse direction, the needle roller moves along the inclined groove under the action of force. When the needle roller reaches the top of the inclined groove, it is limited by the combined action of the inclined groove and the cage, thereby preventing the needle roller from continuing to rotate and causing the entire bearing to rotate in one direction.

[0018] 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.

[0019] Please see Figure 1-11In this embodiment of the utility model, a gear bearing includes a gear 1; multiple arc-shaped plates 2 are integrally provided on the inner side of the gear 1; the inner side of the gear 1 is interference-fitted with a mounting ring 3; multiple notches are provided on the mounting ring 3, and the notches cooperate with elastic plates 8 provided on a mating ring 7. The inner surface of the elastic plate 8 is fixedly installed on the outer surface of the arc plate 2; By adopting the above technical solution, when in use, the needle roller 6 is installed in the rectangular groove opened on the cage 5, and the surface of the needle roller 6 is attached to the inner wall of the outer ring 4, effectively achieving the contact effect, thereby ensuring that the structure installed inside the cage 5 can rotate freely. In this embodiment, a support platform 10 is also provided on the inner side of the mounting ring 3; the support platform 10 is fitted and installed in close contact with the bottom of the boss 9 on the top of the mating ring 7. In this embodiment, multiple elastic plates 8 are provided, and adjacent elastic plates 8 are set at 90°; the elastic plates 8 are integrally provided on the surface of the mating ring 7 at the bottom of the boss 9. By adopting the above technical solution, a mating ring 7 is installed on the surface of the outer ring 4. The elastic plate 8 integrally set on the side wall of the mating ring 7 is effectively fixed to the surface of the arc plate 2 on the inner side of the gear 1, effectively ensuring the mating efficiency of the gear 1 as a whole and the bearing as a whole. Furthermore, the multiple arc-shaped plates 2 arranged on the inner side of the gear 1 are all located between two adjacent elastic plates 8, wherein at least two arc-shaped plates 2 are arranged between two adjacent elastic plates 8. In this embodiment, the inner wall of the mating ring 7 is installed with an interference fit to the outer ring 4; a retainer 5 is provided inside the outer ring 4; and multiple rectangular grooves are provided on the retainer 5 to facilitate the installation of the needle rollers 6. By adopting the above technical solution, the notch opened on the mounting ring 3 is located at the bottom of the elastic plate 8, which effectively avoids the side wall of the mounting ring 3 from blocking the elastic plate 8. At the same time, it also ensures the synchronous rotation of the gear 1 and the bearing. The support platform 10 on the inner side of the mounting ring 3 effectively contacts the bottom of the boss 9, realizing the overall support effect of the mounting ring 3 on the mating ring 7, avoiding the misalignment between the mating ring 7 and the outer ring 4 during use, thereby ensuring the working efficiency of the gear bearing. In this embodiment, the inner wall of the outer ring 4 is provided with a limiting groove 11 at the position of the needle roller 6, and the limiting groove 11 has a sloping groove 13 with an inclined angle and an arc-shaped groove 12 on both sides. The limiting groove 11 is composed of the arc-shaped groove 12 and the sloping groove 13. By adopting the above technical solution, the needle roller 6 is located inside the limiting groove 11. When rotating in the forward direction, the needle roller 6 rotates inside the arc groove 12. At this time, the needle roller 6 can rotate normally. When rotating in the reverse direction, the needle roller 6 moves along the inclined groove 13 under the action of force. When the needle roller 6 moves to the top of the inclined groove 13, the needle roller 6 is limited by the combined action of the inclined groove 13 and the cage 5, thereby preventing the needle roller 6 from continuing to rotate, so that the entire bearing exhibits unidirectional rotation.

[0020] The working principle of this invention is as follows: During use, the needle roller 6 is installed in the rectangular groove opened on the cage 5, and the surface of the needle roller 6 is made to fit against the inner wall of the outer ring 4, effectively achieving contact and thus ensuring that the structure installed inside the cage 5 can rotate freely. A mating ring 7 is installed on the surface of the outer ring 4. The elastic plate 8 integrally set on the side wall of the mating ring 7 is effectively fixed to the surface of the arc plate 2 on the inner side of the gear 1, effectively ensuring the mating efficiency of the gear 1 as a whole and the bearing as a whole. The notch on the mounting ring 3 is located at the bottom of the elastic plate 8, which effectively prevents the side wall of the mounting ring 3 from blocking the elastic plate 8. At the same time, it also ensures the synchronous rotation of the gear 1 and the bearing. The support platform 10 on the inner side of the mounting ring 3 effectively contacts the bottom of the boss 9, realizing the overall support effect of the mounting ring 3 on the mating ring 7. This prevents the mating ring 7 from shifting with the outer ring 4 during use, thereby ensuring the working efficiency of the gear bearing.
