Description

A wheel drive device Technical Field

[0001] This utility model relates to the field of drive device technology, specifically a drive device for a machine wheel. Background Technology

[0002] In the aerospace field, the performance testing of aircraft wheels is a crucial aspect of ensuring flight safety. As a core testing device, the wheel drive device is used to simulate the rotational conditions of aircraft wheels during takeoff and landing. Through contact transmission with the wheels, the wheels are made to reach a set speed, thereby testing key indicators such as the wheel's rotational flexibility, braking performance, and bearing reliability.

[0003] Traditional wheel-driven transmission devices typically employ a fixed-installation friction wheel structure. These friction wheels are constantly exposed, occupying significant space. During aircraft towing and other testing operations, the protruding friction wheels cannot be avoided, easily interfering with aircraft components. This not only disrupts the testing process but may also damage the aircraft and testing equipment. Furthermore, existing devices have limited friction wheel height and position. In actual testing, precise positioning of the aircraft wheel on the friction wheel is crucial. Any deviation in this contact transmission can lead to unstable wheel speed, affecting the accuracy and reliability of test data. Therefore, there is an urgent need for a wheel-driven transmission device with automatic retraction and flexible adjustment capabilities to address the aforementioned problems of existing technologies. Summary of the Invention

[0004] The purpose of this invention is to provide a wheel-driven rotation device to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a wheel-driven rotating device, comprising a rotating equipment platform and a friction wheel, wherein the friction wheel is disposed on one side of the rotating equipment platform, and a flipping adjustment mechanism is provided between the rotating equipment platform and the friction wheel, wherein the flipping adjustment mechanism comprises a flipping angle adjustment frame, a rotating shaft, and an adjustment component, wherein the rotating shaft is rotatably connected inside the rotating equipment platform, the flipping angle adjustment frame fixes both ends of the rotating shaft, the adjustment component is disposed on one side of the rotating shaft, and a receiving groove is provided on one side surface of the rotating equipment platform.

[0006] Preferably, the adjusting assembly includes a lifting gear plate, and a driven gear is fixedly sleeved on the surface of the rotating shaft, with the lifting gear plate meshing with the driven gear.

[0007] Preferably, a lifting cylinder is provided below the lifting tooth plate, the sleeve seat of the lifting cylinder is fixed on the rotating equipment platform, and the output end of the lifting cylinder is fixed at the lower end of the lifting tooth plate.

[0008] Preferably, the friction wheel is rotatably connected between the tilting and adjusting frames, and a drive motor is fixed to one side surface of the tilting and adjusting frame.

[0009] Preferably, the center of one end face of the friction wheel is fixed to the output shaft of the drive motor, a rotating bearing is fixed to one side surface of the tilting and adjusting frame, and the connecting shaft of the friction wheel extends into the interior of the rotating bearing.

[0010] Preferably, a clearance groove is provided on one side surface of the rotating equipment platform, and the receiving groove is connected to the clearance groove.

[0011] This utility model provides a wheel-driven rotation device, which has the following advantages compared with the prior art:

[0012] Through a specially designed flipping adjustment mechanism, the friction wheel is automatically flipped out and reset for storage via a lifting cylinder that drives the lifting gear plate and driven gear. This allows for easy switching between use and idle states, making operation simple and efficient. When idle, the friction wheel can be completely stored in the receiving slot of the rotating equipment platform, flush with the platform surface, greatly reducing space occupation and providing clearance for the landing gear, thus avoiding interference with aircraft towing and other testing operations and ensuring a smooth testing process. The friction wheel is also stored entirely within the rotating equipment platform, effectively reducing the risk of damage from impacts when idle, improving the durability of the rotating equipment, and reducing maintenance costs and equipment replacement frequency.

[0013] The lifting height of the toothed plate can be adjusted to change the tilting angle of the tilting frame, thereby flexibly adjusting the height and position of the friction wheel. This allows it to accurately adapt to different heights and distances of the wheel being suspended, effectively improving contact transmission deviation and ensuring that the wheel rotates stably to the set speed, thus enhancing testing accuracy and reliability.

[0019] 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.

[0020] Please refer to Figures 1-4. This utility model provides a wheel-driven rotating device, including a rotating equipment platform 1 and a friction wheel 2. A flip adjustment mechanism 3 is provided between the rotating equipment platform 1 and the friction wheel 2. The flip adjustment mechanism 3 includes a flip angle adjustment frame 4, a rotating shaft 5 and an adjustment component 6. The rotating shaft 5 is rotatably connected inside the rotating equipment platform 1. The flip angle adjustment frame 4 fixes both ends of the rotating shaft 5. The adjustment component 6 is provided on one side of the rotating shaft 5.

[0021] The rotating equipment platform 1 has an internal receiving slot 7, which is used to store the friction wheel 2 when it is not in use, so as to keep the surface of the device flat and reduce space occupation.

[0022] Friction wheel 2 is set on one side of the rotating equipment platform 1. When the lifting cylinder 11 is started, the lifting cylinder 11 drives the lifting tooth plate 9 to rise, which drives the driven gear 10 to rotate, causing the tilting angle frame 4 and friction wheel 2 to flip out of the receiving groove 7 of the rotating equipment platform 1 until the friction wheel 2 is in contact with the machine wheel. The friction wheel 2 transmits the rotational power to the machine wheel through the friction between its surface and the machine wheel, driving it to reach the set speed.

[0023] The lifting height of the lifting tooth plate 9 can adjust the tilting angle of the tilting frame 4 on the rotating equipment platform 1. The control of the tilting frame 4 to adjust the height and position of the friction wheel 2 can adapt to the height and distance of the machine wheel being suspended, thereby improving the situation where there is a deviation in the contact transmission between the friction wheel 2 and the machine wheel.

[0024] As further shown in Figures 1, 2 and 3, it is worth noting that the adjusting component 6 includes a lifting gear plate 9, a driven gear 10 is fixedly sleeved on the surface of the rotating shaft 5, the lifting gear plate 9 is meshed with the driven gear 10, a lifting cylinder 11 is provided below the lifting gear plate 9, the sleeve seat of the lifting cylinder 11 is fixed on the rotating equipment platform 1, and the output end of the lifting cylinder 11 is fixed at the lower end of the lifting gear plate 9.

[0025] The lifting gear 9 meshes with the driven gear 10 and moves up and down under the drive of the lifting cylinder 11. Through the meshing transmission with the driven gear 10, the linear motion is converted into the rotational motion of the driven gear 10, thereby driving the rotating shaft 5 to rotate and realizing the angle adjustment of the tilting angle frame 4.

[0026] Further, as shown in Figures 1, 2 and 4, it is worth noting that the friction wheel 2 is rotatably connected between the tilting and adjusting frame 4, a drive motor 12 is fixed on one side surface of the tilting and adjusting frame 4, the center of one end face of the friction wheel 2 is fixed on the output shaft of the drive motor 12, a rotating bearing 13 is fixed on one side surface of the tilting and adjusting frame 4, and the connecting shaft of the friction wheel 2 extends into the interior of the rotating bearing 13.

[0027] The drive motor 12 is fixed on one side of the tilting and adjusting frame 4, and its output shaft is fixedly connected to the center of one end face of the friction wheel 2. After starting, it drives the friction wheel 2 to rotate, enabling it to transmit power.

[0028] The rotating bearing 13 is fixed on one side surface of the tilting and adjusting frame 4, and the connecting shaft of the friction wheel 2 extends into it, providing support for the rotation of the friction wheel 2, reducing frictional resistance, and ensuring the smooth rotation of the friction wheel 2.

[0029] As further shown in Figure 1, it is worth noting that a clearance groove 8 is provided on one side surface of the rotating equipment platform 1, and the receiving groove 7 is connected to the clearance groove 8.

[0030] This solution includes the following working process: Before use, the rotating equipment is placed on one side below the machine wheel. During use, the lifting cylinder 11 is activated, which drives the lifting gear plate 9 to rise. Since the lifting gear plate 9 is meshed with the driven gear 10, the driven gear 10 and the rotating shaft 5 rotate inside the rotating equipment platform 1, driving the tilting and adjusting frame 4 and the friction wheel 2 to tilt out of the receiving groove 7 of the rotating equipment platform 1 until the friction wheel 2 contacts the machine wheel. After the drive motor 12 starts, it controls the friction wheel 2 to rotate, so that the machine wheel is driven by the friction wheel 2 to rotate. The speed is turned to the set speed, and finally the lifting cylinder 11 is used to control the friction wheel 2 to return to the rotating equipment platform 1. This allows the friction wheel 2 to be freely switched between being used and idle. After the driving wheel is finished, the friction wheel 2 is automatically stored in the rotating equipment platform 1. When not in use, it is flush with the surface of the equipment platform and occupies less space. It can provide space for the wheel above one side to fall, avoiding interference from the protruding structure to the aircraft towing and other operations during the test. In addition, storing the friction wheel 2 in the rotating equipment platform 1 can also reduce the possibility of collision damage when the rotating equipment is idle.

[0031] During use, the lifting height of the lifting tooth plate 9 can adjust the tilting angle of the tilting frame 4 on the rotating equipment platform 1. After the friction wheel 2 is completely removed from the storage space of the rotating equipment platform 1, the tilting frame 4 will adjust the height and position of the friction wheel 2. This friction wheel 2, which can be flexibly adjusted in height and distance, can adapt to the height and distance of the machine wheel being suspended, thereby improving the situation where there is a deviation in the contact transmission between the friction wheel 2 and the machine wheel.
