Description

Technical Field

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

[0002] Gears are a key component widely used in the field of mechanical transmission. Their main function is to transmit power, change speed, adjust rotation direction or achieve precise motion control through the meshing between teeth. Gear transmission is based on the principle of meshing between teeth. When one gear rotates, its teeth push the teeth of another gear and transmit torque through the interaction force between the tooth surfaces. The speed ratio and torque transmission direction of the gear transmission depend on the ratio of the number of teeth of the two gears and the relative position of the axis. When the number of teeth of the driving gear is less than that of the driven gear, speed increase is achieved; otherwise, speed reduction is achieved. The transmission direction of parallel axis gears is consistent, and staggered axis gears can change the direction of rotation.

[0003] The existing gears with connecting parts have a connecting rod connected to the gear with a groove and a built-in connecting key. The connecting key is a key element for achieving mechanical engagement between the connecting rod and the gear. When the gear to be assembled is sleeved on the connecting rod and aligned with the connecting key in the groove, it is necessary to use professional installation tools such as hammer tools or hydraulic equipment to apply a certain impact force to the gear so that the gear and the connecting key are tightly engaged and fit under the action of the impact force, thereby achieving a firm fixation of the gear on the connecting rod. However, this assembly method must use special tools to apply impact force during the installation process, which increases the complexity of the operation and the dependence on tools, and may not be suitable for simple or quick assembly occasions. At the same time, when the impact force is applied to the gear, if it is not properly controlled, it may cause excessive extrusion between the gear and the connecting key. Excessive extrusion force may not only damage the contact surface of the connecting key or the gear, reducing its service life, but may also cause problems such as gear deformation and connection failure, affecting the performance and stability of the overall transmission system.

[0004] Therefore, it is necessary to provide a new gear with a connecting piece to solve the above technical problems. Utility Model Content

[0024] The utility model is further described below in conjunction with the accompanying drawings and implementation modes.

[0025] In the specific implementation process, Figures 1 to 5 As shown, the gear with a connecting piece includes a gear body 1 and a connecting rod 11 slidably connected to the inner wall of the gear body 1, and an engaging groove 12 is provided on the connecting rod 11. A connecting plate 24 is coaxially arranged on one side of the gear body 1 to ensure synchronization with the movement of the gear body 1. A threaded hole 27 and a sliding groove 8 are sequentially provided on the top of the connecting plate 24 from top to bottom in the vertical direction. A bolt 29 is threadedly connected to the threaded hole 27 of the connecting plate 24. The bottom of the bolt 29 extends into the sliding groove 8 and is slidably connected to a sliding block 10. The two ends of the sliding block 10 are respectively fitted with the inner wall of the sliding groove 8. The bolt 29 can be used to push the sliding block 10 to move vertically toward the inner wall of the engaging groove 12. The sliding connection design between the sliding block 10 and the bolt 29 enables the rotational motion of the bolt 29 to be effectively converted into the linear motion of the sliding block 10.

[0026] An extension end 2 is extended outward from one end of the gear body 1 adjacent to the connecting disk 2 4, and the inner wall of the extension end 2 fits the outer wall of the connecting rod 11. The outer wall of the extension end 2 is fixedly connected with a connecting disk 1 3, and the radial dimension of the connecting disk 1 3 matches the radial dimension of the connecting disk 2 4, ensuring that the two maintain good concentricity and stability after assembly, which is beneficial to subsequent connection and transmission work. The connecting disk 1 3 and the connecting disk 2 4 are provided with a plurality of threaded holes 1 5 in a circular array along their center positions, providing a standardized interface for subsequent connection and fixation. The threaded holes 1 5 of the connecting disk 1 3 and the connecting disk 2 4 are internally threadedly connected with bolts 1 6, and one end of the bolt 1 6 extends out of the threaded hole 1 5 and is threadedly connected with a nut. When the bolt 1 6 is screwed into the threaded hole 1 5 and the nut is tightened, the connecting disk 1 3 and the connecting disk 2 4 are firmly connected by the tensioning force of the bolt 1 6, ensuring that the relative positions of the two are fixed and unchanged, thereby enhancing the stability of the entire gear system.

[0027] The end faces of the sliding block 10 on both sides are vertical, and the two ends of the sliding block 10 are in contact with the two ends of the inner wall of the sliding groove 8. The end faces of the sliding block 10 on both sides are vertical, ensuring that when it slides up and down in the sliding groove 8, the end faces always remain in contact with the two ends of the inner wall of the sliding groove 8, forming a stable sliding guide to prevent deflection or jamming during the sliding process. The bottom of the sliding block 10 is semicircular, and the shape and structure of the connecting rod 11 fitting groove 12 match the sliding block 10, which is conducive to the close fit between the sliding block 10 and the fitting groove 12, and may also reduce the friction resistance during the sliding process. force, improve the smoothness and efficiency of sliding, the shape and structure of the fitting groove 12 on the connecting rod 11 matches the sliding block 10, ensuring that the sliding block 10 can be accurately embedded and stably stay in the fitting groove 12, which helps to achieve a reliable connection between the sliding block 10 and the connecting rod 11, and ensures the effective execution of the transmission or adjustment function. The bottom of the bolt 29 is provided with a light rod part, and the light rod part of the bolt 29 is embedded in the annular groove opened in the sliding block 10. In this way, the rotational motion of the bolt 29 is converted into the linear motion of the sliding block 10, and the precise control of the position of the sliding block 10 is achieved. The cooperation between the light rod part and the annular groove ensures that the transmission relationship between the bolt 29 and the sliding block 10 is stable and accurate.

[0028] The working principle provided by the utility model is as follows: when the utility model is implemented, the gear body 1 is first sleeved on the connecting rod 11 to ensure a good matching relationship between the gear body 1 and the connecting rod 11. The connecting rod 11 can slide smoothly in the gear body 1, providing a basis for subsequent adjustment and fixing operations. The sliding block 10 is placed at the upper end position of the fitting groove 12. At this time, the sliding block 10 and the fitting groove 12 are not in contact. Then, by rotating the bolt 2 9, the bare rod part at the bottom slides in the sliding groove 8, thereby pushing the sliding block 10 to move downward along the sliding groove 8. When the sliding block 10 moves into the fitting groove 12 and fits, it indicates that the connecting rod 11 has been effectively fixed on the gear body 1. Since the transmission between the bolt 2 9 and the sliding block 10 is realized through the annular groove, the bolt 2 9 can maintain stability when the connecting rod 11 rotates, ensuring the durability and reliability of the fixed state of the connecting rod 11.

[0029] Functional expansion: To further increase the functionality of the gear structure, shafts of different shapes can be welded at appropriate positions of the connecting rod 11. These shafts can be used as additional transmission parts, connecting parts or supporting parts. According to the requirements of specific application scenarios, they can be connected with other mechanical components such as connecting rods, bushings, brackets, etc., to achieve multifunctional expansion of the gear structure in transmission, support, positioning, etc.
