Description

Technical Field

[0001] The utility model relates to the technical field of gears, in particular to a combined gear. Background Art

[0002] A gear is a wheel-shaped mechanical component that transmits torque through meshing teeth. By connecting with other toothed mechanical components (such as another gear, a rack, or a worm), it can achieve functions such as changing speed and torque, altering the direction of motion, and changing the form of movement. The interlocking teeth of a gear drive the rotation of another gear, transmitting power. Separating the two gears allows for the use of chains, tracks, or belts to drive the gears on both sides and transmit power.

[0003] A modular gear system is a system composed of multiple gear components, often of varying sizes and types, connected together to achieve specific functions such as transmission ratios, torque transfer, or direction of motion. Modular gears can be custom designed to meet the transmission requirements of various mechanical devices.

[0004] Traditional gear installation methods are often complicated, requiring the use of multiple professional tools and cumbersome operation steps. This not only increases the difficulty of the assembly workers' work, but also consumes a lot of time in scenarios where frequent gear replacement or repair is required. The traditional installation method is inconvenient to disassemble, resulting in some slightly damaged gears unable to be replaced in time, which in turn affects the transmission accuracy and efficiency of the entire transmission system. Therefore, a combination gear is proposed to solve the above problems. Utility Model Content

[0027] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0028] Reference Figure 2 and Figure 3 The present invention provides an embodiment of a gear assembly, comprising a gear body 1 having a plurality of connection holes 2 defined therein, a mounting mechanism disposed within the connection holes 2, and a reinforcement mechanism disposed within the gear body 1. The gear body 1 is the core of the gear assembly and provides the basic structural framework for the entire gear assembly. The plurality of connection holes 2 provide space for the mounting mechanism, and the reinforcement mechanism within the gear body 1 contributes to improved overall performance.

[0029] The mounting mechanism includes a connecting post 3, the exterior of which is removably connected to the inner wall of a connecting hole 2. The primary function of the connecting hole 2 is to accommodate the connecting post 3 within the mounting mechanism. The presence of the connecting hole 2 allows the connecting post 3 to be accurately mounted on the gear body 1. It is a key structure for connecting the various components of the combined gear and provides the necessary interface for assembly of the entire combined gear. A transmission gear 8 is rotatably connected to the outer wall of the connecting post 3. The connecting post 3 provides a mounting position for the transmission gear 8. The structural stability of the connecting post 3 is crucial to the entire mounting mechanism. It withstands the forces transmitted by the transmission gear 8 and, through its connection to the connecting hole 2, ensures the accurate relative position of the transmission gear 8 and the gear body 1, guaranteeing transmission accuracy. The interior of the connecting post 3 is provided with a groove 4 on both the front and rear sides. A rotating plate 5 is rotatably connected to the inner wall of the groove 4. The groove 4 provides a rotational space for the rotating plate 5, limiting its range of motion so that it can only rotate within the groove 4. This ensures that the rotating plate 5 moves in the predetermined direction when squeezed by the transmission gear 8, making it a key structure for the installation and removal of the transmission gear 8. Springs 6 are fixedly connected to the adjacent sides of the two rotating plates 5. These adjacent sides of the two springs 6 are fixedly connected to the adjacent inner walls of the two grooves 4. During the installation of the transmission gear 8, the springs 6 are squeezed by the rotating plates 5, compressing and storing energy. When the transmission gear 8 is fully installed, the springs 6 release their energy to reset the rotating plates 5. During removal, they also provide the resetting force for the rotating plates 5, ensuring smooth installation and removal. A rotating ball 7 is rotatably connected to the bottom of the rotating plates 5, and the bottom side of the transmission gear 8 contacts the top side of the gear body 1. When the transmission gear 8 is installed, the rotating ball 7 contacts the top side of the transmission gear 8, cooperating with the rotating plates 5 to longitudinally limit the transmission gear 8, thereby reducing friction between the transmission gear 8 and the rotating plates 5, making the installation and rotation of the transmission gear 8 smoother and improving transmission efficiency. The distal sides of the two rotating plates 5 contact the inner wall of the transmission gear 8. The bottoms of the two rotating balls 7 contact the top of the transmission gear 8. The bottom end of the connecting column 3 is fixedly connected to a limit plate 9, the top of which contacts the bottom of the gear body 1. The main function of the limit plate 9 is to limit the axial movement of the connecting column 3 within the connecting hole 2, ensuring that the connecting column 3 is in a stable position after installation, thereby ensuring the stability of the entire installation mechanism and preventing the connecting column 3 from loosening during operation.

[0030] Reference Figure 1 and Figure 2The reinforcing mechanism includes teeth 15, the inside of the teeth 15 is fixedly connected to the outside of the gear body 1, and the outside of the teeth 15 is provided with a wear-resistant layer. The teeth 15 are the key structure for realizing the gear transmission function. It meshes with the teeth 15 of other gears to accurately transmit power. And the wear-resistant layer (titanium nitride) provided on the outside of the teeth 15 improves the wear resistance and corrosion resistance of the teeth 15, and extends the service life of the gear. An axial hole 10 is provided inside the gear body 1. The axial hole 10 provides space for the connection between the gear body 1 and the mounting shaft. It is the key part for connecting the entire gear with the external transmission system. A plurality of card grooves 11 are provided on the inner wall of the axial hole 10. The card grooves 11 play a role in positioning and installation during the installation process. A plurality of mounting holes 12 are provided on the gear body 1 near the outside of the axial hole 10. The mounting hole 12 works together with the card groove 11 to be responsible for the stable installation and fixation of the mounting shaft. The gear body 1 is internally provided with multiple reinforcing ribs 13 and a plurality of through-holes 14. The ribs 13, in conjunction with the through-holes 14, primarily function to reduce the weight of the gear without compromising its overall structural strength. This reduced weight reduces the burden of the gear's own weight on the entire mechanical system, thereby improving its efficiency while maintaining the gear's structural stability.

[0031] Working principle: by aligning the transmission gear 8 with the top of the connecting column 3 and pressing it downward, the transmission gear 8 will squeeze the rotating plate 5 during its downward movement, and the squeezed rotating plate 5 will move inward and squeeze the spring 6. When the transmission gear 8 completely enters the connecting column 3, the rotating plate 5 loses the squeezing of the transmission gear 8 and rotates outward due to the pressure generated by the compression of the spring 6, and cooperates with the rotating ball 7 to limit the transmission gear 8 longitudinally, thereby realizing the rapid installation of the transmission gear 8. The installation can be completed with a simple pressing operation. When disassembly is required, the two rotating plates 5 can be pressed in the middle, and then the transmission gear 8 can be pulled up to complete the disassembly.

[0032] During installation, the slot 11 provided on the inner shaft hole 10 of the gear body 1 plays an important role in positioning and installation. It can accurately determine the installation position and provide a precise reference for subsequent component installation. At the same time, the mounting hole 12 that cooperates with the slot 11 is responsible for firmly installing and fixing the mounting shaft. The synergistic effect of these two ensures the correct positioning and stable connection of the gear in the mechanical structure. The reinforcing rib 13 provided on the gear body 1 cooperates with the through hole 14 to effectively reduce the weight of the entire gear without affecting the overall structural strength of the gear. This design helps to meet transmission requirements while reducing the burden of the gear's own weight on the entire mechanical system, thereby improving the efficiency of the mechanical system. The wear-resistant layer provided on the teeth 15 is made of titanium nitride. Titanium nitride has high hardness and excellent wear resistance, which can improve the wear resistance and corrosion resistance of the teeth 15. The wear-resistant layer greatly improves the overall performance of the combined gear and can effectively resist the wear caused by the teeth 15 during long-term meshing transmission, thereby extending the service life of the gear and maintaining a stable transmission effect.

[0033] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent replacements for some of the technical features therein. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
