Abstract
The utility model relates to a magnetic-gravity spiral organ, belonging to the instructional instrument research field, which comprises a straight iron wire shaft and a circular-ring shaped magnet. The lower end of the straight iron wire shaft is hanging, the straight iron wire shaft passes through the center of the circular-ring shaped magnet. The utility model uses the interact of the magnet force and the gravity so as to generate the spiral movement, and the hanging lower end of the shaft with the aid of the magnetic force causes the spiral moving body to accomplish the transformation between the spiral dynamic energy and the spiral potential energy without contacting with the shaft track. The utility model has the advantages that: the utility model also can be used in the industrial automation design and the toy design.
Description
Affiliated technical field
Magnetic gravity screw device belongs to instruments used for education technical research field.
Background technology
In physics teaching, need demonstrate the motion process of object during research object of which movement rule with some instruments used for education, analyze the reproduction of moving rule, such as conversion and the conservation of mechanical energy of demonstrating kinetic energy and potential energy with bead lifting on level and smooth track, conservation of mechanical energy was discussed in this way still in calendar year 2001 " high school physics newly compiles teaching material ".The law of conservation of mechanical energy derives under constant force and straight-line situation, the application of the law of conservation of mechanical energy is not limited to constant force and rectilinear motion, no matter whether external force is constant force, no matter object is done rectilinear motion or curvilinear motion, this law is all set up.Problem is that the mode of teaching demonstration motion is too simple, and object when carrying out energy conversion essential contact by track.Variation motion teaching demonstration more cleverly not only can sharpen understanding, and can also increase the entertaining of study, cultivates comprehensive application ability, improves people's cultural quality.The utility model is just from student's quality-oriented education, and the design by Magnetic gravity screw device realizes diversified helical motion demonstration.
Summary of the invention
The purpose of this utility model is to interact to produce helical motion automatically demonstration spiral kinetic energy and the transfer process of spiral potential energy under the situation that does not contact track by magnetic force, gravity.
The utility model is achieved in that with the unsettled straight iron wire in lower end as axle, allow straight iron wire axle pass the central authorities of a circular ring type magnet, the thickness of circular ring type magnet is less than the diameter of interior ring, straight iron wire axle and the interior ring of circular ring type magnet edge spacing are greater than 2 times of shaft diameter, less than 5 times of shaft diameter, because the magnetic field graviational interaction of magnet, straight iron wire axle can cause eccentric fulcrum with the absorption of magnet ring inner edge, the center of gravity out of trim run-off the straight of magnet ring self causes eccentric fulcrum displacement, repeat this process magnet ring and will helical motion axially take place automatically down around straight iron wire, arrive unsettled end around the helical motion of straight iron wire axle, magnet ring is not to continue the support that downward spiral breaks away from straight iron wire axle to fall down, and returns the certain height that rests on straight iron wire axle but overcome action of gravity and the spiral inertia spiral that makes progress under the graviational interaction in magnetic field.See accompanying drawing.
Description of drawings
Accompanying drawing is the longitudinal profile structural map of Magnetic gravity screw device, the unsettled straight iron wire axle 2. circular ring type magnets 3. helical motion directions in 1. lower ends among the figure.
Embodiment
The helical motion that Magnetic gravity screw device utilizes the interaction of magnetic force and gravity to produce nature, and making the conversion of finishing spiral kinetic energy and spiral potential energy under the situation of spiral kinetoplast at engagement shaft track not by magnetic force in the empty lower end of axle suspension, this can't accomplish in teaching demonstration instrument in the past.This device not only can be used for teaching demonstration, can also be used for the design of industrial automation design and toy, produces novel practical product.
