Description

Technical Field

[0001] This utility model relates to the field of inertial wheel technology, and in particular to a dual-purpose inertial wheel that combines magnetic induction and frictional resistance. Background Technology

[0002] A dual-purpose inertial wheel combining magnetic induction and frictional resistance is a device that combines two different physical phenomena: magnetic induction and frictional resistance. It is mainly used to study and demonstrate the interaction between inertia, magnetic field, and friction. This device typically consists of a wheel, a magnet, and a friction material.

[0003] Magnetic induction:

[0004] Magnets are installed on the wheels, which can generate magnetic fields. When the wheels rotate, the magnetic field rotates with the wheels, thereby inducing an electromotive force (electromagnetic induction) in the surrounding conductors. According to Lenz's law, the induced electromotive force will generate a reverse magnetic field, which will hinder the rotation of the wheels, thus producing a braking effect.

[0005] Frictional resistance:

[0006] There is friction between the wheel and the ground or other contact surfaces. This friction hinders the rotation of the wheel and generates resistance. By adjusting the coefficient of friction between the wheel and the contact surface, the magnitude of the frictional resistance can be changed.

[0007] Currently, most inertial wheels are expensive to manufacture, cause significant environmental pollution, and have complex assembly processes, making them unsuitable for high-speed applications. Utility Model Content

[0008] The purpose of this invention is to address the aforementioned shortcomings in the existing technology by proposing a dual-purpose inertial wheel that combines magnetic induction and frictional resistance.

[0009] To achieve the above objectives, the present invention adopts the following technical solution:

[0010] Design a dual-purpose inertial wheel that combines magnetic induction and frictional resistance, comprising a ring, wherein the ring has multiple annular grooves inside, and adjacent annular grooves are equally spaced. The cross-section of the annular groove is trapezoidal, and the annular groove is filled with an iron core, the shape of which is matched with the internal shape of the annular groove.

[0011] The inner side of the ring is provided with a first limiting hook, the end of which is welded to the inner wall of the ring. The inner side of the ring is also provided with two second limiting hooks of the same specification, one end of which is welded to the inner wall of the ring.

[0012] In detail, an end cap is provided on one side of the ring, and a first limiting post is provided on one side of the end cap. One end of the first limiting post is welded to the surface of the end cap, and the first limiting post and the first limiting hook are arranged alternately.

[0013] In detail, a second limiting post is also provided on one side of the ring. One end of the second limiting post is welded to the surface of the end cap, and the inner corner of the second limiting post is fitted with the inner corner of the second limiting hook.

[0014] In detail, a first wheel axle bearing is provided through the center of the end cover, and the connection between the first wheel axle bearing and the end cover is fixed by welding.

[0015] In detail, an inner sleeve is also provided through the surface of the end cap, and the connection between the inner sleeve and the end cap is fixed by welding.

[0016] In detail, a back cover is provided on the other side of the ring, and a second wheel axle bearing is provided through the center of the back cover. The connection between the second wheel axle bearing and the back cover is fixed by welding. The second wheel axle bearing has the same specifications as the first wheel axle bearing and their positions correspond.

[0017] In detail, the back cover has several threaded posts on one side of the ring. One end of the threaded post is welded to the surface of the back cover, and the surface of the threaded post penetrates the interior of the inner sleeve. The other end of the threaded post is threaded with a threaded cap, and the end face of the threaded cap is tightly fitted with the end face of the inner sleeve.

[0018] The design scheme proposed in this utility model has the following beneficial effects in application:

[0019] 1. Make an inverted trapezoidal cross-section annular groove on the inner side of the ring to increase radial tension. Weld three iron hooks (evenly distributed) on the inner side of the ring. The iron hooks welded on the ring are designed to be W-shaped, with the welding points located on both sides and at the center of the ring cross-section. The other two hooks can be located at the center or moved to both sides by the same distance to increase the adhesive force in the circumferential direction.

[0020] 2. Both methods increase adhesion, reduce gaps, and prevent magnetism loss, thereby eliminating jerky sensations and enhancing the comfort experience.

[0021] 3. Add an iron sheet to the inverted trapezoidal groove inside the ring to optimize the distribution of the magnetic field. This also reduces the amount of strong magnets used, thereby reducing costs and improving production efficiency. Attached Figure Description

The annular grooves 11 are filled with iron cores 12, and the shape of the iron cores 12 is matched with the internal shape of the annular grooves 11.

[0030] A first limiting hook 13 is provided on the inner side of the ring 10. The end of the first limiting hook 13 is welded to the inner wall of the ring 10. Two second limiting hooks 14 of the same specification are also provided on the inner side of the ring 10. One end of the second limiting hook 14 is welded to the inner wall of the ring 10.

[0031] An inverted trapezoidal cross-section annular groove 11 is opened on the inner side of the ring 10 to increase radial tension. Three iron hooks (evenly distributed) are welded on the inner side of the ring 10. The iron hooks welded on the ring 10 are designed to be W-shaped, with the welding points located on both sides and at the center of the cross-section of the ring 10. The other two hooks can be located at the center or moved to both sides by the same distance to increase the adhesive force in the circumferential direction.

[0032] By increasing adhesion, reducing gaps, and avoiding magnetism loss, the jerky feeling is eliminated, enhancing the comfortable experience.

[0033] Adding an iron core 12 inside the inverted trapezoidal groove on the inner side of the ring 10 optimizes the distribution of the magnetic field and reduces the amount of strong magnets used, thereby reducing costs and improving production efficiency.

[0034] It should be further explained that an end cap 20 is provided on one side of the ring 10, and a first limiting post 21 is provided on one side of the end cap 20. One end of the first limiting post 21 is welded to the surface of the end cap 20, and the first limiting post 21 and the first limiting hook 13 are arranged alternately.

[0035] It should be further noted that a second limiting post 22 is also provided on one side of the ring 10. One end of the second limiting post 22 is welded to the surface of the end cap 20, and the second limiting post 22 is fitted with the inner corner of the second limiting hook 14.

[0037] It should be further noted that an inner sleeve 202 is also provided through the surface of the end cap 20, and the connection between the inner sleeve 202 and the end cap 20 is fixed by welding.

The connection between the second wheel axle bearing 31 and the back cover 30 is fixed by welding. The second wheel axle bearing 31 has the same specifications as the first wheel axle bearing 201 and their positions correspond.

[0039] It should be further noted that the back cover 30 is provided with several threaded posts 32 on one side of the ring 10. One end of the threaded post 32 is welded to the surface of the back cover 30, and the surface of the threaded post 32 penetrates the interior of the inner sleeve 202. The other end of the threaded post 32 is threadedly connected to a threaded cap 33, and the end face of the threaded cap 33 is tightly fitted to the end face of the inner sleeve 202.

[0040] Working method: When it is necessary to splice the ring 10, end cap 20 and back cap 30, the end cap 20 covers one side of the ring 10, and then the first limiting post 21 can be staggered with the first limiting hook 13, and the inner corner of the second limiting post 22 can be engaged with the second limiting hook 14, so that the limiting post and the limiting hook can be matched, thereby improving the bonding effect between the end cap 20 and the ring 10.
