[0024] The following will clearly and completely describe the technical solutions in the embodiments of the present utility model with reference to the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part rather than all of the embodiments of the present utility model. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0025] Before introducing the technical solutions of this application, several technical terms involved in this application are first explained:

[0026] Bearing: A bearing is an important component in modern mechanical equipment. Its main function is to support the mechanical rotating body, reduce the friction coefficient during its movement, and ensure its rotation accuracy.

[0027] Flange: A flange generally refers to a disk-shaped metal body with several fixing holes on its periphery for connecting other things, and it is widely used in machinery.

[0028] Flat key: A flat key is a mechanical fitting that relies on two sides as working surfaces to transmit torque through extrusion with the side surfaces of the keyway.

[0029] Skeleton oil seal: A skeleton oil seal is a mechanical seal element used to prevent lubricating oil leakage.

[0030] Such as Figures 1-3As shown in the figure, a mounting and fixing structure for the rotary input shaft of the auxiliary gantry of a human upward three-way stacker includes an attachment transmission box body 1, a transmission shaft 2, bearings 3, and bearing flanges 4. The transmission shaft 2 is arranged on the attachment transmission box body 1. One bearing 3 is arranged at each of the upper and lower ends of the transmission shaft 2, and one bearing flange 4 is arranged at each of the upper and lower ends of the transmission shaft 2. The bearing flange 4 is closely fitted with the bearing 3 to achieve the function of rotary transmission. The design of the upper and lower groups of bearing flanges 4 and their cooperation mode with the rotary transmission shaft 2 are the core parts for realizing the functions of this patent. By adopting the design of the bearing flange 4, the original rotary shaft sleeve is replaced, avoiding the complexity and high cost of the post-welding processing of the rotary shaft sleeve of the attachment transmission box, reducing the manufacturing difficulty and cost. The structural design of the upper and lower groups of bearing flanges 4 makes the disassembly and assembly process simpler and faster, improving work efficiency. By removing the bearing flange 4, the rotary transmission shaft can be conveniently overhauled and maintained, improving the reliability and service life of the equipment, making the overall structure more concise, reducing unnecessary space occupation, and improving the integration and use efficiency of the equipment.

[0031] As Figures 1-3As shown in the figure, an installation hole 5 is provided on one side of the attachment transmission box body 1. The installation hole 5 is adapted to the transmission shaft 2. The rotating transmission shaft 2 is processed according to the design requirements to have a shaft diameter and length that match the bearing 3, as well as a flat key groove or other connection structure for connecting with the bearing flange 4. The transmission shaft 2 is installed on the attachment transmission box body 1 by passing through the installation hole 5. The bearing flange 4 is provided with a bearing installation hole position adapted to the bearing 3. The bearing 3 is installed into the bearing installation hole position of the bearing flange 4 to ensure a tight fit without clearance between the bearing 3 and the hole position. The upper and lower two groups of bearing flanges 4 cooperate to rotate the transmission shaft 2. The upper and lower two groups of bearing flanges 4 are designed, and each group of bearing flanges 4 has precise bearing installation hole positions for installing the bearing 3 and supporting the rotating transmission shaft 2. The rotating transmission shaft 2 passes through the upper and lower two groups of bearing flanges 4 and closely cooperates with the bearing 3 to achieve the rotating transmission function. Through reasonable structural design, it is ensured that the connection between the upper and lower two groups of bearing flanges 4 and the rotating transmission shaft 2 is stable and reliable, and can withstand various forces and torques during the working process. One bearing 3 is respectively passed through the upper and lower ends of the transmission shaft 2. The rotating transmission shaft 2 passes through the upper and lower two groups of bearing flanges 4, and the transmission shaft 2 is connected and fixed to the bearing flange 4 using a flat key 6 or other connection methods. One bearing flange 4 is respectively passed through the upper and lower ends of the transmission shaft 2. The bearing installation hole position on the bearing flange 4 closely cooperates with the bearing for rotating transmission. The bearing flange 4 is precisely processed with bearing installation hole positions according to the design requirements to ensure that the size and position accuracy of the hole positions meet the bearing installation requirements. At the same time, an interface for connecting with the attachment transmission box or other fixed structures is processed. The bearing flange 4 is fixedly connected to the transmission shaft 2 through a flat key 6. A skeleton oil seal 7 is tightly installed between the bearing 3 and the bearing flange 4 to prevent the lubricating oil on the bearing 3 and the bearing flange 4 from leaking. One end of the transmission shaft 2 is also provided with a transmission gear 9 through a backing plate 8. The upper and lower two groups of bearing flanges 4 are connected to the attachment transmission box body 1 or other fixed structures through bolts 10 or other fasteners to ensure the stability and reliability of the overall structure. High-strength, wear-resistant, and corrosion-resistant steel is selected as the material for the bearing flange 4 and the rotating transmission shaft 2 to ensure that it has sufficient strength and durability under long-term working conditions. After the assembly is completed, the overall structure is debugged to ensure that the rotating transmission shaft can rotate smoothly without jamming. A load test is carried out to simulate the actual working conditions and test the bearing capacity and stability of the overall structure. Through this design, this patent successfully replaces the traditional design scheme that relies on the rotating shaft sleeve of the attachment transmission box and undergoes complex post-welding processing as the bearing installation hole position, thus solving the problems of difficult post-welding processing, high processing cost, difficult disassembly and assembly, and difficult maintenance of the rotating shaft sleeve of the attachment transmission box.

[0032] Although embodiments of the present utility model have been shown and described, those of ordinary skill in the art can understand that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principle and spirit of the present utility model. The scope of the present utility model is defined by the appended claims and their equivalents.
