[0002] In physics teaching and research, a thorough exploration of the laws governing the motion of objects in rotating systems is crucial. This research helps us better understand and apply fundamental physical concepts such as inertial force and centrifugal force. To achieve this, experimental setups are typically used to simulate and observe related physical phenomena. Take the "pancake rotation" phenomenon as an example; this is a classic physics problem involving the dynamics of rotation. To study this phenomenon, a disc-shaped device is needed. This device must be able to simulate a specific rotational motion of the object to mimic the pancake's rotation. Through detailed observation and analysis of this rotational motion, we can gain a deeper understanding of how inertial and centrifugal forces affect the motion of objects and their roles in actual physical systems.

[0003] Existing disc devices used to study physical phenomena such as "pancake rotation" have limited functionality and cannot meet the diverse needs of research on combined translational and rotational motions. Furthermore, they cannot freely adjust relevant parameters according to requirements, thus failing to obtain more valuable data and analysis. Utility Model Content

[0030] The present invention will be further described below with reference to the accompanying drawings and specific embodiments, so that those skilled in the art can better understand and implement the present invention. However, the embodiments are not intended to limit the present invention.

[0031] Reference Figures 1-5 As shown, this utility model discloses a multifunctional adjustable parameter translational rotating disk, comprising:

[0032] Base 1;

[0033] Drive source 2 is mounted on base 1;

[0034] The drive gear 3 is coaxially mounted on the output shaft of the drive source 2.

[0035] Driven gear 4, there are three driven gears 4, which are rotatably connected to the base 1 respectively. The three driven gears 4 are arranged in an equilateral triangle around the driving gear 3 and mesh with it. At the same time, each driven gear 4 has a number of pin holes 41 arranged around its rotation center at the end away from the base 1. The distance between each pin hole 41 and the rotation center of the driven gear 4 is different. Among them, three pin holes 41 with the same distance from the rotation center of the driven gear 4 form a pin hole group.

[0036] The bracket 5 is connected to the three pin holes 41 of a set of pin holes by three pins 53 arranged in an equilateral triangle.

[0037] Tray 6 is coaxially mounted on bracket 5.

[0038] Specifically, this multifunctional adjustable translational rotating disk is used as a demonstration tool in physics teaching to help students understand physical concepts such as inertial force, centrifugal force, non-inertial frames of reference, and multi-body motion. This embodiment provides a specific structure for a driven gear 4. The driven gear 4 has four pin holes 41 arranged at 90-degree intervals around its rotation center, with each pin hole 41 at a different distance from its rotation center. The pin holes 41 on the driven gear 4 are grouped, with three pin holes 41 spaced at the same distance from the rotation center of the driven gear 4 forming a group of four pin-connecting holes for connecting the bracket 5. The bracket 5 has three through holes 511 arranged in an equilateral triangle, each through hole 511 movably fitted with a pin shaft 53. The three pin shafts 53 are respectively inserted into the three pin holes 41 of a pin-connecting hole group.

[0039] Specifically, the drive source 2 drives three driven gears 4 to rotate synchronously via the drive gear 3. The synchronously rotating driven gears 4 drive the bracket 5 and the tray 6 mounted on it to translate along a circular trajectory. By adjusting different sets of pin holes connected to the bracket 5 (i.e., pin holes 41 with different distances from the rotation centers of the driven gears 4), the translation radius can be adjusted. At the same time, by adjusting the rotation direction and speed of the drive source 2, the rotation direction and speed of the rotational motion can be adjusted.

[0040] This invention relates to a multifunctional adjustable translational rotating disk, which can perform diverse experiments involving combined translational and rotational motions. Furthermore, the parameters related to the experiment can be easily adjusted according to requirements, thereby simulating rotational motion under various experimental conditions or parameters. This allows for more accurate simulation and observation of rotational motions, and the acquisition of more valuable data and analysis.

[0041] Reference Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown, the base 1 further includes a base plate 11, on which a support seat 12 is coaxially arranged. The drive source 2 is mounted on the support seat 12, and the support seat 12 is provided with three mounting shafts 13 arranged in an equilateral triangle around the output shaft of the drive source 2. Three driven gears 4 are rotatably connected to one of the mounting shafts 13. Specifically, the base plate 11 is a circular plate, the support seat 12 has a centrally symmetrical structure, and the support seat 12 is coaxially arranged on the base plate 11. The base plate 11 is provided with multiple limiting members for fixing the support seat 12; the support seat 12 has a mounting groove 121 for mounting the drive source 2, and the drive source 2 is mounted in the mounting groove 121.

[0042] Furthermore, the support base 12 has a mounting groove 121 that matches the shape of the drive source 2, and the drive source 2 is fitted into the mounting groove 121.

[0043] Furthermore, a circular groove is coaxially provided at one end of the driven gear 4, and a cross-shaped connector is vertically connected in the groove. The connector includes a central through hole and four ribs arranged at 90-degree intervals around it. Each rib has a pin hole 41 parallel to the central through hole.

[0044] Furthermore, the bracket 5 includes an annular body 51, on which a plurality of limiting plates 52 are vertically arranged at even intervals around its circumference.

[0045] Furthermore, the tray 6 has a disc structure, and the side of each limiting plate 52 near the inner circle of the main body 51 is an arc surface that matches the circumference of the tray 6. Specifically, the arc surfaces of multiple limiting plates 52 are on the same circle, and the limiting plates 52 and the main body 51 form a receiving position that matches the shape of the tray 6, in which the tray 6 is placed.

[0046] Furthermore, the main body 51 has three through holes 511 arranged in an equilateral triangle, and a pin 53 is inserted into each of the three through holes 511. Specifically, the through holes 511 are countersunk holes, so that when the pin 53 is installed, the end of the pin 53 will be recessed into the through hole 511, so that the tray 6 can be stably installed on the bracket 5.

[0047] Furthermore, the tray 6 is manufactured using electroplating wire drawing and mirror polishing processes, and its coefficient of friction meets the following conditions: 0.15 - 0.30 with lubricated sliding friction, 0.30 - 0.40 without lubricated sliding friction, 0.05 - 0.10 with lubricated rolling friction, and 0.10 - 0.12 without lubricated rolling friction.

[0048] Furthermore, the outer diameter of the driving gear 3 is smaller than the outer diameter of the driven gear 4.

[0049] Furthermore, both the driving gear 3 and the driven gear 4 adopt a herringbone tooth profile. Herringbone tooth profile gears can achieve smoother transmission and have higher load capacity and lower noise.

[0050] Furthermore, the drive source 2 adopts a servo motor.

[0051] Obviously, the above embodiments are merely illustrative examples for clear explanation and are not intended to limit the implementation. Those skilled in the art will recognize that other variations or modifications can be made based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. However, obvious variations or modifications derived therefrom are still within the protection scope of this invention.
