Description

Technical Field

[0001] This utility model relates to the field of AGV (Automated Guided Vehicle) technology, and in particular to an AGV wheel. Background Technology

[0002] With the continuous improvement of modern industrial automation, Automated Guided Vehicles (AGVs) have been widely used in logistics handling, warehouse management, and intelligent manufacturing. As one of the key walking components of AGVs, the wheels not only need to have good load-bearing capacity and smooth operation, but also need to integrate drive and deceleration functions to meet the design requirements of compact space, reasonable structure, and efficient transmission.

[0003] Currently, most common AGV wheels use an external motor and reducer structure, where the motor is connected to the reducer via a coupling or synchronous belt, and the reducer then drives the wheel to rotate. While this structure provides stable transmission, it results in a larger overall size, which is not conducive to a compact layout of the vehicle structure, and also increases the complexity and maintenance costs of the system. Utility Model Content

It employs a two-stage planetary gear set series transmission structure, where the input shaft sequentially drives the first and second planetary gear sets to achieve multi-stage reduction, improving transmission efficiency and load-bearing capacity, and meeting the operational needs of the AGV under complex working conditions. By setting a first and second step on the inner wall of the receiving cavity and assembling the first and second bearings respectively, the gear ring is supported at both ends, enhancing the connection rigidity and stability between the reducer and the wheel hub. This effectively reduces vibration and noise during operation and improves the smoothness of the AGV's movement.

The inner wall of the receiving cavity 3 is provided with a first step 4 and a second step 5. A first bearing 6 and a second bearing 7 are respectively provided on the first step 4 and the second step 5. The reducer 2 includes an input shaft 8, a gear ring 9, a first planetary gear set 10, and a second planetary gear set 11. The input shaft 8 meshes with the input end of the first planetary gear set 10, and the output end of the first planetary gear set 10 meshes with the input end of the second planetary gear set 11. The two ends of the outer wall of the gear ring 9 are respectively connected to the first bearing 6 and the second bearing 7. The end of the hub 1 is connected to the output end of the second planetary gear set 11.

[0027] This invention integrates the reducer 2 directly into the hub 1, eliminating the need for the traditional coupling or synchronous belt drive structure between the external motor and the reducer, significantly reducing the overall size and facilitating a compact layout within the AGV's overall space. A two-stage planetary gear set series transmission structure is adopted, with the input shaft 8 sequentially driving the first planetary gear set 10 and the second planetary gear set 11, achieving multi-stage reduction, improving transmission efficiency and load-bearing capacity, and meeting the AGV's operational needs under complex working conditions. By setting a first step 4 and a second step 5 on the inner wall of the receiving cavity 3, and respectively assembling the first bearing 6 and the second bearing 7, the gear ring 9 is supported at both ends, enhancing the connection rigidity and stability between the reducer 2 and the hub 1, effectively reducing vibration and noise during operation, and improving the AGV's smoothness.

[0028] This embodiment describes an AGV wheel. The first planetary gear set 10 includes multiple first planetary gears 12 and a first connecting member 13. Each of the first planetary gears 12 is rotatably mounted on the first connecting member 13. The input shaft 8 meshes with the first planetary gears 12, and each of the first planetary gears 12 meshes with the gear ring 9. A connecting shaft 14 is located in the middle of the first connecting member 13, and the connecting shaft 14 meshes with the input end of the second planetary gear set 11. Specifically, the multiple first planetary gears 12 are evenly distributed around the gear ring 9, ensuring balanced transmission and load-bearing capacity. Simultaneously, the connecting shaft 14 enables stable power transmission between the first planetary gear set 10 and the second planetary gear set 11, improving the transmission efficiency and operational smoothness of the entire reducer 2 system.

[0029] This embodiment describes an AGV wheel, in which the second planetary gear set 11 includes multiple second planetary gears 15 and a second connecting member 16. Each of the second planetary gears 15 is rotatably mounted on the second connecting member 16. The connecting shaft 14 meshes with the second planetary gears 15, and each of the second planetary gears 15 meshes with the gear ring 9. The wheel hub 1 is connected to the middle of the second connecting member 16. Specifically, the second planetary gear set 11 also employs multiple planetary gears meshing with the gear ring 9 to further improve the reduction ratio and load-bearing capacity. Through the connection between the second connecting member 16 and the wheel hub 1, power is ultimately stably output to the wheel hub 1, ensuring the continuity and stability of wheel operation, which is beneficial for improving the response accuracy and smoothness of the AGV during operation.

[0030] In this embodiment, an AGV wheel is described, wherein the wheel hub 1 is detachably connected to the middle of the second connecting member 16 via a fastener 17. Specifically, the use of a detachable fastener 17 connection method facilitates assembly and subsequent maintenance, reducing repair costs and replacement difficulty; at the same time, it ensures the firmness and reliability of the connection between the wheel hub 1 and the second connecting member 16, without affecting the overall transmission performance.

[0031] In this embodiment, an AGV wheel has an input flange 18 at one end of the hub 1 near the input shaft 8. Specifically, the input flange 18 provides an installation interface between the wheel and the external drive device, improving installation convenience and enhancing the strength and stability of the connection, which is beneficial to improving the overall system integration.

[0032] In this embodiment, an AGV trolley wheel is provided with a positioning ring 19 at one end of the input flange 18 near the reducer 2. A third bearing 20 is provided on the inner wall of the positioning ring 19, and an input connector 21 is provided on the inner wall of the third bearing 20. The input connector 21 is connected to the input shaft 8. Specifically, by providing the positioning ring 19 and the third bearing 20, the coaxiality and rotational stability between the input connector 21 and the input shaft 8 are effectively improved, reducing energy loss and mechanical wear caused by eccentricity or vibration, thereby improving transmission efficiency and service life.

[0033] The AGV wheel described in this embodiment has a rubber ring 22 on the outer periphery of the hub 1. Specifically, the rubber ring 22 not only increases the friction between the wheel and the ground, enhancing traction performance, reducing noise, but also improves the stability of AGV operation and its ability to adapt to complex ground environments.
