Description

Technical Field

[0001] This utility model relates to the field of drive wheel structure technology, specifically to a modular high-torque drive wheel. Background Technology

[0002] Robot drive wheels are a crucial component of robot mobility systems, primarily responsible for providing power and steering. Drive wheels typically consist of components such as motors, reducers, and gears, and their rotation propels the robot forward. Drive wheels utilize reducers to achieve high torque capabilities, meeting the torque demands of production machinery. The main function of the reducer is to reduce the motor's speed while increasing the output torque. A higher reduction ratio in the reducer results in a lower motor speed and a higher output torque.

[0003] To meet different production needs, the output torque of the motor can be changed by replacing the reducer with a different reduction ratio. The existing drive wheel structure, which includes the motor and reducer, is mostly an integrated structure. Replacing the reducer is a complicated process, which in turn affects the production process. Utility Model Content

[0029] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0030] like Figures 1-5 As shown, this utility model provides a technical solution: a modular high-torque drive wheel, comprising:

[0031] Alloy bracket 1, with a rotating shaft 11 rotatably connected to the inner wall of alloy bracket 1, and a drive wheel body 12 fixedly installed at the left end of rotating shaft 11;

[0032] The convenient maintenance mechanism 2 is located on the top of the alloy bracket 1. The convenient maintenance mechanism 2 is used to facilitate the operator to adjust the drive structure located inside the machine body.

[0033] Modular assembly mechanism 3 is located on the side of alloy bracket 1. Modular assembly mechanism 3 is used to modularly divide the drive structure for easy maintenance.

[0034] As one implementation method in this embodiment, such as Figure 1 , Figure 2 As shown, the convenient maintenance mechanism 2 includes a sleeve 21, which is fixedly installed on the top of the alloy bracket 1. A rotating disk 22 is rotatably connected to the inner wall of the sleeve 21. An organic body connecting disk 24 is fixedly installed on the top of the rotating disk 22. A fixing bolt 23 is threadedly connected to the outer wall of the sleeve 21. The threaded end of the fixing bolt 23 extends into the inner cavity of the sleeve 21 and is movably connected to the outer wall of the rotating disk 22. During installation, this structure is installed on the machine body from the machine body connecting disk 24, which will make the drive wheel body 12 located on the outside of the machine body. If maintenance is required on the drive structure on the other side of the alloy bracket 1, the fixing bolt 23 is loosened so that its thread is away from the outer wall of the rotating disk 22. Then, the sleeve 21 and the alloy bracket 1 can be rotated with the rotating disk 22 as a reference, thereby adjusting the drive structure to the outside of the machine body for easy maintenance. After maintenance, the alloy bracket 1 is reset and rotated, and then the fixing bolt 23 is tightened so that its threaded end is attached to the outer wall of the rotating disk 22 to lock the position of the alloy bracket 1.

[0035] As one implementation method in this embodiment, such as Figure 1 , Figure 3As shown, the modular assembly mechanism 3 includes a drive motor 31 and a reducer 32. A first connecting block 34 is fixedly connected to the output shaft of the drive motor 31, a first connecting sleeve 33 is fixedly connected to the input shaft of the reducer 32, and a second connecting sleeve 35 is fixedly connected to the output shaft of the reducer 32. The first connecting block 34 is movably inserted into the inner cavity of the first connecting sleeve 33, and a second connecting block 36 is movably inserted into the inner cavity of the second connecting sleeve 35. The second connecting block 36 is fixedly installed on the right end of the rotating shaft 11 and is connected to the first connecting sleeve 33 via the first connecting sleeve 34. The shape design of block 34 allows the first connecting block 34 to be inserted into the first connecting sleeve 33, enabling the transmission connection between the drive motor 31 and the reducer 32. The shape design of the second connecting sleeve 35 and the second connecting block 36 allows the second connecting block 36 to be inserted into the second connecting sleeve 35, enabling the transmission connection between the reducer 32 and the rotating shaft 11. Thus, the drive motor 31, the reducer 32 and the rotating shaft 11 can be divided into three modules, making it convenient for users to replace the reducer 32 with different reduction ratios to meet the needs of production.

[0036] As one implementation method in this embodiment, such as Figure 1 , Figure 4 , Figure 5As shown, the modular assembly mechanism 3 also includes a strip block 37 and a positioning frame 38. The strip block 37 is fixedly installed on the right side of the alloy bracket 1. A smooth rod 371 is fixedly installed on the outer wall of the strip block 37. A sliding block 372 is slidably connected to the outer wall of the smooth rod 371. A bolt 373 is threadedly connected to the outer wall of the sliding block 372. The threaded end of the bolt 373 is movably connected to the outer wall of the smooth rod 371. A motor support sleeve 374 is fixedly installed on the right side of the sliding block 372. The drive motor 31 is fixedly installed on the inner wall of the motor support sleeve 374. The positioning frame 38 is fixedly installed on the right side of the alloy bracket 1. The inner cavity of the positioning frame 38... The positioning frame 38 and the insertion leg 381 are movably connected. A support frame 386 is fixedly installed on the right side of the insertion leg 381. The reducer 32 is fixedly installed on the inner wall of the support frame 386. The top of both the positioning frame 38 and the insertion leg 381 are provided with circular connecting holes 382. A connecting rod 383 is movably inserted into the inner cavity of the circular connecting hole 382. A limit plate 384 is fixedly installed on the top of the connecting rod 383. A magnetic block 385 is fixedly installed on the inner wall of the limit plate 384. The bottom of the magnetic block 385 is magnetically connected to the top of the positioning frame 38. When replacing the reducer 32, first loosen the bolt 373 so that its end is away from the smooth rod 37. The outer wall of the first connecting block 372 can be slid upward on the outer wall of the smooth rod 371. Through the transmission of the motor support sleeve 374, the drive motor 31 can be moved upward, so that the first connecting block 34 is vertically withdrawn from the inside of the first connecting sleeve 33. Then the limiting plate 384 is pulled upward, causing the connecting rod 383 to withdraw from the circular connecting hole 382 of the positioning frame 38 and the plug leg 381, releasing the state of locking the plug leg 381 in the positioning frame 38. Subsequently, the plug leg 381 can be withdrawn from the positioning frame 38, completing the disassembly of the reducer 32. At the same time, the second connecting sleeve 35 is moved horizontally from the second connecting block 36. After removing the reducer 32, the new reducer 32 is replaced. Then, the second connecting sleeve 35 is inserted into the second connecting block 36, and the connecting leg 381 is inserted into the positioning frame 38. Then, the connecting rod 383 is inserted into the circular connecting hole 382. The positioning frame 38 is made of iron alloy, and the magnetic block 385 is magnetically attracted to the positioning frame 38, thus completing the installation of the reducer 32. Then, the first connecting block 34 is inserted into the first connecting sleeve 33, and the bolt 373 is tightened so that its threaded end is attached to the outer wall of the smooth rod 371, thus completing the positioning of the drive motor 31 and realizing the replacement of the reducer 32.

[0037] Working principle: During installation, the structure is installed on the machine body from the connecting plate 24, with the drive wheel body 12 located on the outside of the machine body. During operation, the drive motor 31 is controlled to work, transmitting power to the reducer 32. The reducer 32 then reduces the speed, increasing the torque, which in turn drives the drive wheel body 12 to rotate via the rotating shaft 11, providing the power for the machine body to move. During maintenance, if the reducer 32 is to be replaced to change the torque, loosen the fixing bolt 23 so that its thread is away from the outer wall of the rotating plate 22. Then, the sleeve 21 and alloy bracket 1 can be rotated using the rotating plate 22 as a reference, thereby adjusting the drive structure to the outside of the machine body. First, loosen the bolt 373 so that its end is away from the outer wall of the smooth rod 371, and then... The outer wall of the slide bar 371 slides upward against the slide block 372, causing the first connecting block 34 to be vertically removed from the inside of the first connecting sleeve 33. Then, the limiting plate 384 is pulled upward, causing the connecting rod body 383 to be removed from the circular connecting hole 382 of the positioning frame 38 and the plug leg 381. Subsequently, the plug leg 381 can be removed from the positioning frame 38, completing the disassembly of the reducer 32. At the same time, the second connecting sleeve 35 is horizontally removed from the second connecting block 36. Then, a new reducer 32 is replaced, and the reducer 32 is reset and installed. After installation, the alloy bracket 1 is reset and rotated, and then the fixing bolt 23 is tightened so that its threaded end is attached to the outer wall of the rotating disk 22 to lock the position of the alloy bracket 1.

[0038] The above embodiments are only used to illustrate the technical solution of this utility model, and are not intended to limit it.
