Description

Technical Field

[0001] This utility model relates to the field of intelligent warehousing equipment technology, specifically to a walking speed reducer, which is particularly suitable for the transmission system design of automatic loading and unloading AGV trolleys. Background Technology

[0002] In the field of smart warehousing, AGVs (Automated Guided Vehicles) are core equipment, and the performance of their travel reducers directly affects the stability, synchronization, and space utilization of the equipment. Traditional AGV reducers have the following problems:

[0003] Low transmission efficiency: Some structures use a single gear transmission, which is prone to power loss when changing direction;

[0004] Insufficient synchronization: When multiple reducers work together, the distributed power system results in poor coordination between walking and lifting movements;

[0005] Large size and weight: Traditional steel structures are difficult to meet the requirements of lightweight design, increasing the energy consumption of AGVs;

[0006] Poor flexibility in assembly and disassembly: Low degree of modularity, making it difficult to quickly customize for different warehousing scenarios.

[0007] Therefore, there is an urgent need for a new type of walking speed reducer that is small in size, highly synchronized, and easy to assemble and disassemble, in order to improve the overall performance of AGV vehicles. Utility Model Content

[0008] To address the problems mentioned in the background section, this invention provides a walking speed reducer. By optimizing the transmission structure, material selection, and modular design, it solves the problems of poor synchronization, large size and weight, and inconvenient assembly and disassembly in existing AGV speed reducers.

[0009] Overall structure

[0010] The walking speed reducer consists of three speed reduction mechanisms: AGV walking speed reducer A, AGV walking speed reducer B, and intermediate speed reducer, which achieve synchronous movement through a transmission mechanism.

[0011] The core component is the AGV walking reducer B, which includes a reduction gearbox, cylindrical gear one, an output shaft, cylindrical gear three, and a spiral bevel gear. Cylindrical gear one, cylindrical gear three, and spiral bevel gear are mounted in the reduction gearbox via a rotating shaft, and cylindrical gear two is mounted on the output shaft.

[0012] Transmission direction conversion: One end of the shaft of the cylindrical gear three is fixed with a bevel gear, which meshes with the spiral bevel gear to achieve a 90° transmission direction conversion, avoiding interference between the output shaft and the connecting rod.

[0013] Synchronous transmission: AGV walking reducer A and AGV walking reducer B are connected to the intermediate reducer through a connecting rod. The intermediate reducer is driven by a servo motor, and power is transmitted through gear meshing to achieve synchronous operation of the three reducers.

[0014] Functional expansion: The two output shafts of the intermediate reducer are used to connect to the lifting reducer, so as to achieve unified power for walking and lifting movements.

[0015] The gearbox and key components are made of high-strength aluminum alloy, which reduces the overall weight by 50% compared to steel, balancing strength and lightweight.

[0016] Adopting a modular structure, each reducer can be disassembled and installed independently, and supports customization of transmission ratio, installation method and expansion functions according to customer needs.

[0017] Compared with the prior art, the beneficial effects of this utility model are:

[0018] Small size and light weight: The aluminum alloy material and compact gear layout reduce installation space and lower AGV energy consumption.

[0019] Excellent synchronization: A single power source servo motor drives the walking and lifting systems in a unified manner through a reducer, ensuring coordinated movements.

[0020] Highly efficient and stable transmission: The combination of spiral bevel gears and cylindrical gears enables direction conversion, resulting in high transmission efficiency and avoiding interference.

[0021] Flexible assembly and disassembly: The modular design supports rapid assembly and personalized customization, adapting to different warehousing scenarios. Attached Figure Description

[0031] A type of travel speed reducer.

[0032] This implementation plan addresses the technical problems existing in the prior art, such as those disclosed in the background section above: "In the field of intelligent warehousing, AGVs (Automated Guided Vehicles) are core equipment, and the performance of their travel reducers directly affects the stability, synchronization, and space utilization of the equipment. Traditional AGV reducers suffer from low transmission efficiency: some structures use single gear transmission, which easily leads to power loss during direction changes; insufficient synchronization: when multiple reducers work together, the dispersed power system results in poor coordination between walking and lifting movements; large size and weight: traditional steel structures cannot meet the requirements of lightweight design, increasing AGV energy consumption; and poor disassembly and assembly flexibility: low modularity makes it difficult to quickly customize according to different warehousing scenarios." In practical terms, this problem is clearly real and difficult to solve. Therefore, to solve this technical problem, a travel reducer is provided.

[0033] like Figure 1-4 As shown in the figure;

[0034] Based on the above, a transmission system consisting of three speed reducers is described. The speed reducers move synchronously through the transmission mechanism. Each speed reducer includes an AGV walking speed reducer A1, an intermediate speed reducer 2, an AGV walking speed reducer B3, and a servo motor 5. The intermediate speed reducer 2 includes a reduction gearbox 21, a first cylindrical gear 22, an output shaft 23, a third cylindrical gear 24, and a spiral bevel gear 25. The first cylindrical gear 22, the third cylindrical gear 24, and the spiral bevel gear 25 are mounted within the reduction gearbox 21 via rotating shafts. A second cylindrical gear 26 is mounted on the output shaft 23. The first cylindrical gear 22 meshes with the second cylindrical gear 26, and the second cylindrical gear 26 meshes with the third cylindrical gear 24. A bevel gear 27 is fixed to one end of the rotating shaft of the third cylindrical gear 24. The bevel gear 27 meshes with the spiral bevel gear 25 to change the transmission direction.

[0035] The transmission mechanism is a connecting rod 4, which is a high-strength rigid connecting rod to ensure synchronous transmission accuracy.

[0036] The AGV walking reducer A1 and AGV walking reducer B3 are connected to the intermediate reducer 2 via connecting rod 4 to form a synchronous transmission system.

[0037] The output shaft 23 of the intermediate reducer 2 is used to connect the lifting reducer to realize the power integration of walking and lifting actions.

[0038] The gearbox and key components are made of high-strength aluminum alloy, which reduces the overall weight by 50% compared to steel.

[0039] Assembly process:

[0040] Cylindrical gear one, cylindrical gear three, and spiral bevel gear are fixed inside the gearbox via a rotating shaft. The output shaft passes through the gearbox and cylindrical gear two is installed thereon, ensuring that cylindrical gear one meshes with cylindrical gear two and cylindrical gear two meshes with cylindrical gear three.

[0041] Install a bevel gear at the end of the shaft of cylindrical gear three, so that it meshes precisely with the spiral bevel gear at a transmission angle of 90°.

[0042] The output shaft of the intermediate reducer 2 is connected to the lifting reducer, and the transmission ends of the AGV walking reducer A1, AGV walking reducer B3 and intermediate reducer 2 are fixed by the connecting rod 4 to form a synchronous transmission system.

[0043] The output shaft of the servo motor 5 is connected to the input shaft of the intermediate reducer 2 to provide a power source.

[0044] Work process:

[0045] Servo motor 5 drives cylindrical gear 1 to rotate, and transmits power to cylindrical gear 3 through cylindrical gear 2. Cylindrical gear 3 drives bevel gear to rotate, and the bevel gear meshes with the spiral bevel gear to change the transmission direction, driving AGV walking reducer A1 to operate.

[0046] The AGV walking reducer A1 drives the AGV walking reducer B3 to move synchronously through the connecting rod 4, realizing the movement of the AGV trolley; at the same time, the output shaft of the intermediate reducer 2 drives the lifting reducer to realize the loading and unloading of goods.
