Technical Field

[0001] This utility model relates to the field of mechanical transmission technology, and in particular to a gear drive structure that can adapt to various working conditions. Background Technology

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0019] According to an embodiment of the present invention, a gear drive structure that can adapt to various working conditions is provided.

[0020] The present invention will now be further described in conjunction with the accompanying drawings and specific embodiments, such as... Figure 1-3 As shown, a gear drive structure adaptable to various working conditions according to an embodiment of the present invention includes a power motor 1, a first station gear 2, a second station gear 3, a third station gear 4, an idler gear structure 5, an idler gear structure 6, an idler gear structure 7, and a main station 8. A support frame 11 is provided below the power motor 1, and an encoder speed change device 12 is fixedly installed on the side of the support frame 11. A drive gear 9 is fixedly installed at the output end of the power motor 1, and the drive gear 9 is connected to the main station 8 through meshing with its driven gear. The first station gear is distributed around the main station 8. 2. Station gear 2 3 and station gear 3 4, idler gear structure 2 6 is installed between main station 8 and station gear 1 2, idler gear structure 3 7 is installed between main station 8 and station gear 2 3, and idler gear structure 1 5 is installed between main station 8 and station gear 3 4. Idler gear structure 1 5, idler gear structure 2 6 and idler gear structure 3 7 each have two gears meshing with each other. The idler gear structure can adopt a modular design, which supports quick disassembly and assembly to adapt to different transmission path requirements. The idler gear structure is fixed to the base by buckles or bolts, which supports quick replacement or addition and removal to meet the transmission requirements under different working conditions.

[0021] In one embodiment, the bottom of each of the idler gear structure 1 5, idler gear structure 2 6, and idler gear structure 3 7 is provided with a base 10, and the top surface of the base 10 is fixed with two support shafts connected to the gears by bolts. With this structure, the gears of the idler gear structure 1 5, idler gear structure 2 6, and idler gear structure 3 7 are detachable, making it easy to change the number of idler gear structures or the number of teeth of the idler gear structures.

[0022] In one embodiment, the number of teeth on idler gear structures 5, 6, and 7 is interchangeable. Idler gear structures 5, 6, and 7 are identical in structure, and at least one idler gear structure is provided. By changing the number of idler gears, the rotation direction of gears at different workstations can be changed. When the number of idler gears is odd, the driven gear rotates in the opposite direction to the drive gear 9; when the number of idler gears is even, they rotate in the same direction. By changing the number of teeth on the idler gears (e.g., from 20 teeth to 30 teeth), the transmission ratio is changed, and the speed of the driven gear is adjusted.

[0023] In one embodiment, mounting legs 13 are welded to the four corners at the bottom of the support frame 11, and the support frame 11 is fixedly connected to the mounting base at the bottom of the power motor 1 by bolts. This structure provides a mounting platform for the power motor 1 and the encoder speed change device 12.

[0024] In one embodiment, one gear of idler gear structure 5 is meshed with the main station 8, and the other gear of idler gear structure 5 is meshed with station gear 4. One gear of idler gear structure 6 is meshed with the main station 8, and the other gear of idler gear structure 6 is meshed with station gear 2. One gear of idler gear structure 7 is meshed with the main station 8, and the other gear of idler gear structure 7 is meshed with station gear 3. With this structure, it is easy to drive the rotation of station gear 2, station gear 3, and station gear 4 through idler gear structure 5, idler gear structure 6, and idler gear structure 7.

[0025] In one embodiment, the encoder speed change device 12 is composed of a support frame 11, a right-angle gearbox, a proximity switch, a cam plate, and an encoder. By changing the speed ratio of the right-angle gearbox, the speed of the encoder is changed to adapt to different working conditions. The principle of the encoder speed change device 12 is an existing known technology, and there are mature products available. Therefore, its principle will not be further explained.

[0026] Working principle:

[0027] In operation, the power motor 1 is first started, causing the drive gear 9 at the output end of the power motor 1 to drive the main station 8 to rotate using its matching driven gear. During this process, the idler gear structures 5, 6, and 7 surrounding the main station 8 rotate in a gear meshing manner, and drive the station gears 2, 3, and 4 to rotate respectively. The idler gears, as intermediate gears, do not directly drive the load, but can change the transmission direction and speed between adjacent gears. By changing the number of idler gears (i.e., idler gear structure 5, 6, or 7), the rotation direction of different station gears can be changed. When the number of idler gears is odd, the driven gear rotates in the opposite direction to the drive gear 9; when the number of idler gears is even, they rotate in the same direction. By changing the number of teeth on the idler gears (e.g., from 20 teeth to 30 teeth), the transmission ratio is changed, and the speed of the driven gear is adjusted. This design allows for flexible adjustment of the transmission path according to actual needs, thus adapting to different working conditions. Increasing or decreasing the number of teeth directly affects the transmission ratio, thereby adjusting the output speed. The gear transmission structure features fixed speed, no slippage, and no relative change in speed, ensuring the stability and reliability of the overall structure.

[0028] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
