Description

Technical Field

[0001] This utility model relates to the field of mechanical transmission components, and in particular to a high-torque output gear shaft. Background Technology

[0002] In mechanical transmission systems, gear shafts are key components for transmitting power and torque. Traditional gear shafts are prone to problems such as tooth surface wear, breakage, or deformation when subjected to high torque, leading to reduced transmission efficiency or even failure. Current technologies typically improve torque-carrying capacity by increasing the gear shaft diameter or using high-strength materials, but this increases weight and cost with limited effectiveness. To address these issues, a solution is proposed below. Utility Model Content

[0003] The purpose of this invention is to provide a high-torque output gear shaft, which has the advantages of simple structure, high transmission efficiency, and good stability.

[0004] The above-mentioned technical objective of this utility model is achieved through the following technical solution: A high-torque output gear shaft includes a gear with a long shaft and a short shaft connected to its two ends respectively. The other end of the long shaft is connected to a right input shaft, and the other end of the short shaft is connected to a left output shaft. The structure of the right input shaft is the same as that of the left output shaft. Both the right input shaft and the left output shaft include a power shaft. The power shaft is provided with several long spline grooves. The other end of the power shaft is sequentially connected to a first connecting shaft and a second connecting shaft. The other end of the second connecting shaft is connected to a fixed shaft, which is provided with several short spline grooves.

[0005] Preferably, the outer diameters of the power shaft, the first connecting shaft, the second connecting shaft, and the fixed shaft decrease sequentially, and the outer edges and connecting parts are all arc-shaped.

[0006] Preferably, the gear has a right-end spoke groove and a left-end spoke groove on both sides.

[0007] Preferably, one end of the right-side input shaft is provided with a connecting hole.

[0008] Preferably, a center hole is provided at one end of the left output shaft.

[0009] The beneficial effects of this utility model are as follows: 1. The gear facilitates the meshing connection between the gear shaft and the gear components inside the gearbox. Several long spline grooves enable meshing and transmission between the gear shaft and the gear components inside the gearbox. Several short spline grooves also enable meshing and transmission between the gear shaft and the gear components inside the gearbox. Furthermore, the combination of long and short spline grooves in both locations can further increase the transmission torque of the gear shaft, thereby increasing its practicality.

[0010] 2. The right and left spoke grooves reduce the weight of the parts while ensuring the strength required for high gear torque, making the gear shaft lightweight. This improves the smoothness and transmission efficiency of the gear shaft rotation. The connecting hole facilitates the fixing of the gear shaft to the gearbox components, and the center hole facilitates the positioning and installation of the gear shaft, ensuring a more accurate installation position.

[0013] The following description is merely a preferred embodiment of this utility model, and the scope of protection is not limited to this embodiment. All technical solutions falling within the scope of this utility model's concept should be protected. Identical components are represented by the same reference numerals. It should be noted that the terms "front," "rear," "left," "right," "up," and "down" used in the following description refer to directions in the accompanying drawings, while the terms "bottom" and "top," "inner" and "outer" refer to directions toward or away from the geometric center of a specific component.

[0014] like Figures 1 to 2 As shown, a high-torque output gear shaft includes a gear 1, which facilitates meshing with a gear component 1 inside the gearbox. A long shaft 2 and a short shaft 3 are connected to both ends of the gear 1. The other end of the long shaft 2 is connected to a right input shaft 4, and the other end of the short shaft 3 is connected to a left output shaft 5. The structure of the right input shaft 4 is the same as that of the left output shaft 5. Both the right input shaft 4 and the left output shaft 5 include a power shaft 6, which has several long spline grooves 7. These long spline grooves 7 allow the gear shaft to mesh with the gear component 1 inside the gearbox for transmission. The other end of the power shaft 6 is connected to the first connecting shaft 8 and the second connecting shaft 9 in sequence. The other end of the second connecting shaft 9 is connected to the fixed shaft 10. The fixed shaft 10 is provided with several short spline grooves 11. The gear shaft can also mesh with the gear 1 component inside the gearbox through the several short spline grooves 11. Furthermore, the combination of the long spline grooves 7 and the short spline grooves 11 in the two parts can further increase the transmission torque of the gear shaft, thereby further increasing the practicality of the gear shaft.

[0015] The outer diameters of the power shaft 6, the first connecting shaft 8, the second connecting shaft 9, and the fixed shaft 10 decrease sequentially, and the outer edges and connecting parts are all arc-shaped, which can effectively prevent the gear shaft from scratching the internal parts of the gearbox during installation, and at the same time make the gear shaft rotate more smoothly.

[0016] The gear 1 has a right-end spoke groove 12 and a left-end spoke groove 13 on both sides. The right-end spoke groove 12 and the left-end spoke groove 13 can reduce the weight of the parts while ensuring the strength required for the high torque of the gear, so that the gear shaft can be lightweight, thereby improving the smoothness and transmission efficiency of the gear shaft during rotation.

[0017] One end of the right input shaft 4 is provided with a connecting hole 14, which facilitates the fixing of the gear shaft to the gearbox components. One end of the left output shaft 5 is provided with a center hole 15, which facilitates the positioning and installation of the gear shaft, ensuring a more accurate installation position.

[0018] The specific embodiments described above further illustrate the technical problems, technical solutions, and beneficial effects of this utility model. It should be understood that the above descriptions are merely specific embodiments of this utility model and are not intended to limit this utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
