Technical Field
[0001] The utility model relates to the technical field of mechanical props, in particular to a working condition simulation platform for a mechanical transmission device. Background Technique
[0002] Mechanical transmission simulation props are tools used to display and simulate the principles of mechanical transmission. They can help people better understand the working principles and motion modes of mechanical transmission. Gear combination transmission toys usually consist of multiple gears and can be driven by manual rotation or other power sources to display the transmission relationship and motion effects between gears. They usually consist of multiple gears and can be driven by manual rotation or other power sources to display the transmission relationship and motion effects between gears.
[0003] Among them, the larger the transmission ratio between gears, the fewer the number of rotations of the driven gear per rotation of the driving gear, and the lower the rotational speed of the driven gear; the smaller the transmission ratio, the relatively higher the rotational speed of the driven gear. In the process of simulating gear transmission with existing mechanical transmission simulation props, the required large and small driving and driven gears are connected, and the driving gear is rotated to drive the driven gear connected to the outside of the driving gear, so that the rotational speeds of driven gears of different specifications are different. However, after rotation, it is impossible to directly show the comparison of different rotational speeds under different specifications of the driven gear, which is not conducive to the intuitive display of gear transmission. At the same time, when it is necessary to install and compare the driving and driven gears of different specifications, it is also inconvenient to adjust and replace the positions of the gears back and forth. Content of the Utility Model
[0004] The purpose of the utility model is to provide a working condition simulation platform for a mechanical transmission device to solve the problems raised in the above background technique.

A rotating rod is fixedly connected to the center of the driven wheel model, and one end of the rotating rod is rotatably connected to the front slider. A rear slideway is opened on the rear fixing plate, and a rear slider is slidably connected to the inner wall of the rear slideway. One end of the rear slider is rotatably connected with a lead screw, and one end of the lead screw is engaged with the rotating rod. A slider is threadedly connected to the lead screw.

[0011] When the active wheel model of the utility model is rotated, a plurality of driven wheel models with different sizes meshed with its outer wall can be driven to rotate self - rotatably.

[0018] The present utility model will be described in detail below. The technical solutions in the embodiments of the present utility model are clearly and completely described. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without making creative efforts belong to the protection scope of the present utility model.
[0019] The present utility model provides a working condition simulation platform for a mechanical transmission device by improvement. The technical solution of the present utility model is as follows:
[0020] In the embodiment of the present utility model, as Figures 1-4As shown in the figure, a working condition simulation platform for a mechanical transmission device includes a front fixing plate 1, a rear fixing plate 3, a driving wheel model 2, and a driven wheel model 21. The front fixing plate 1 is a carrier for bearing simulation props. When using the device to simulate gear transmission, the driving wheel model 2 can be installed through the center of the front fixing plate 1 at this time, so that the driving wheel model 2 can rotate at the center of the front fixing plate 1. A front slideway 11 is provided on the front fixing plate 1, and a front slider 12 is slidably connected to the inner wall of the front slideway 11. After the front slider 12 is connected to the rotating rod 22 fixedly connected to the center of the driven wheel model 21, the driven wheel model 21 can rotate on one side of the front slider 12 and is horizontally corresponding to the driving wheel model 2. The driving wheel model 2 is rotatably connected to the center of the front fixing plate 1. A fixing block 34 is fixedly connected to one side of the rear slider 32, and a slide rod 351 is fixedly connected to the fixing block 34. The slide rod 351 is located on one side of the lead screw 35. The lead screw 35 is fixedly connected to the rotating rod 22 at the center of the driven wheel model 21, and one end of the rotating rod 22 is rotatably connected to the front slider 12. A rear slideway 31 is provided on the rear fixing plate 3, and a rear slider 32 is slidably connected to the inner wall of the rear slideway 31. One end of the rear slider 32 is rotatably connected to a lead screw 35, and one end of the lead screw 35 is snap-connected to the rotating rod 22. A slider 36 is threadedly connected to the lead screw 35. A fixing block 34 is fixed on one side of the rear slider 32, and a slide rod 351 parallel to the lead screw 35 is fixed on one side of the fixing block 34. One end of the slider 36 is sleeved on the slide rod 351. By sliding the front slider 12 on the inner wall of the front slideway 11, the front slider 12 can drive the driven wheel model 21 installed on one side thereof to be horizontally corresponding to the driving wheel model 2 at the center of the front fixing plate 1, so that the simulator can make the outer wall of the driven wheel model 21 mesh with the outer wall of the driving wheel model 2. Thus, when controlling the driving wheel model 2 to rotate, the driven wheel model 21 meshed with the outer wall of the driving wheel model 2 can be driven to rotate, so that the driven wheel model 21 can rotate. When the driven wheel model 21 rotates, it can drive the lead screw 35 to rotate, and the slide rod 351 can guide the slider 36, so that the slider 36 slides along the slide rod 351. When the user rotates the driving wheel model 2, it can drive a number of driven wheel models 21 with different sizes meshed with its outer wall to rotate self. When the number of rotations of the driven wheel models 21 is different due to their different sizes, the number of rotations of the lead screw 35 is the same. And the sizes of the lead screws 35 installed on each driven wheel model 21 are the same, so that the displacements of the sliders 36 installed on each driven wheel model 21 are different when the lead screws 35 rotate, thereby intuitively displaying the amount of motion change. At the same time, the position of the front slider 12 in the front slideway 11 and the position of the rear slider 32 on the inner wall of the rear slideway 31 can be adjusted according to the actual size of the gear required, ensuring that the device intuitively displays the gear transmission.
[0021] In an embodiment of the present utility model, a front threaded rod 13 is rotatably connected to the inner wall of the front slideway 11. The front threaded rod 13 penetrates through the outer wall of the front fixing plate 1. The front slider 12 is threadedly sleeved on the front threaded rod 13. A clamping groove 121 matching with one end of the rotating rod 22 is formed on the front slider 12. The front threaded rod 13 rotatably connected to the inner wall of the front slideway 11 is threadedly connected to the front slider 12, enabling the staff to rotate the outer end of the front threaded rod 13 to make the front threaded rod 13 rotate on its own axis, so that the position of the front slider 12 threadedly connected to the front threaded rod 13 on the inner wall of the front slideway 11 can be adjusted. The clamping groove 121 is used to engage with one end of the rotating rod 22 fixedly connected to the center of the driven wheel model 21. Since both the rotating rod 22 and the clamping groove 121 are cylindrical, it can rotate on one side of the front slider 12.
[0022] In an embodiment of the present utility model, docking blocks 23 are fixedly connected to the joints of the rotating rod 22 and the lead screw 35. Corresponding connecting grooves 231 are formed on the docking blocks 23. The connecting grooves 231 on the two docking blocks 23 are bolted together. The docking blocks 23 fixedly connected to the joints of the rotating rod 22 and the docking blocks 23 are used to make them correspond to each other, so that the connecting grooves 231 correspond to each other. At this time, the slider 36 can be fixedly installed at one end of the rotating rod 22 through the bolt connection between the connecting grooves 231, enabling it to rotate synchronously with the driven wheel model 21.
[0023] In an embodiment of the present utility model, a square clamping groove 221 is formed at one end of the rotating rod 22. A square block matching with the square clamping groove 221 is fixedly connected to one end of the lead screw 35. When the slider 36 is connected to one end of the rotating rod 22, at this time, the square block fixedly connected to one end of the slider 36 can be engaged with the square clamping groove 221 formed at one end of the rotating rod 22, so that the slider 36 can be firmly clamped and connected to the rotating rod 22.
[0024] In an embodiment of the present utility model, a limiting rod 33 is fixedly connected to the inner wall of the rear slideway 31. The limiting rod 33 is slidably connected to the rear slider 32. The limiting rod 33 fixedly connected to the inner wall of the rear slideway 31 is used to make way for the displacement of the rear slider 32, so that the position of the rear slider 32 can correspond to the position of the front slider 12 slidably connected to the inner wall of the front slideway 11, ensuring that one end of the lead screw 35 is limited by the rear fixing plate 3, the rear slideway 31 and the rear slider 32.
[0025] The working principle of a working condition simulation platform for a mechanical transmission device provided by the present utility model is as follows: By installing the driving wheel model 2 and the driven wheel model 21 at the center of the front fixing plate 1 and on one side of the front slider 12 respectively, at this time, the driven wheel model 21 can be rotationally connected with the front slider 12, so that the position where the driven wheel model 21 is located can slide the front slider 12 to adjust its position, enabling the simulation personnel to adjust the position of the front slider 12. The outer wall of the driven wheel model 21 is meshed with the outer wall of the driving wheel model 2. At this time, the rear slideway 31 opened on the rear fixing plate 3 on one side of the front fixing plate 1 can slide the rear slider 32, so that the rear slider 32 drives the position of the slider 36 to be adjusted to a position corresponding to the front slider 12, enabling one end of the slider 36 to be engaged and connected with the rotating rod 22, so that the slider 36 can rotate synchronously with the driven wheel model 21. Thus, when the user rotates the driving wheel model 2, it can drive several driven wheel models 21 with different sizes meshed on its outer wall to rotate. When several driven wheel models 21 rotate, due to the influence of their different sizes, the rotation speed and the number of rotation circles of the driven wheel models 21 are different. When the number of rotation circles is different, the lead screw 35 generates the same number of rotation circles. And the sizes of the lead screws 35 installed on each driven wheel model 21 are the same, so that the displacement amounts of the sliders 36 installed on each driven wheel model 21 are different when the lead screw 35 rotates. Thus, the device can visually display the motion change amount when the main and driven wheels rotate. At the same time, according to the actual required size of the gear, the position of the front slider 12 in the front slideway 11 can be adjusted, and at the same time, the position of the rear slider 32 on the inner wall of the rear slideway 31 can be adjusted to ensure that the device visually displays the transmission of the gear.
[0026] Although the embodiments of the present utility model have been shown and described, for those of ordinary skill in the art, it can be understood 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.
