The utility model adopts strong magnetic materials, applies the mutual exclusion principle of same magnetic poles of a magnet and uses electric mechanical transmission to form a magnetic levitation vibration system and realize non-contact magnetic suspension forced vibration. The vibrator completely overcomes the deficiencies in the operation of a spring-mechanical vibrator and is provided with good synchro-frequency, good responsivity and stable resonance phenomenon.
Description
Affiliated technical field
The utility model relates to a kind of teaching demonstration apparatus, particularly a kind of magnetic suspension vibrating instrument that is used to demonstrate mechanical vibration.
Background technology
At present, high school physics textbook all will relate to the experimental study of phenomenons such as forced vibration, resonance when introducing the mechanical vibration related content.Existing middle school physical experiment chamber is equipped with the device that can demonstrate such experiment, is generally the spring mechanical vibration gauge.This device is owing to due to the defective of self structure, often cause the same frequency of when experiment forced vibration relatively poor, promptly observe f to be forced to=responsiveness that f drives is bad.In addition, also since the mechanical frequency modulation part of this device by experimenter's manual operation, the randomness when being subjected to manual operation influences, making needs the resonance effect instability demonstrated in the forced vibration, wayward.
Summary of the invention
It is a kind of good with property frequently, responsiveness that the purpose of this utility model is to provide, the magnetic suspension vibrating instrument that resonance effect is stable.
The utility model is achieved in that a kind of magnetic suspension vibrating instrument, it is characterized in that: it is by upper bracket, be fixed in the transparent standpipe of upper bracket, magnetic levitation oscillator in the transparent standpipe, lower carriage, the vibrating arm of installing on the lower carriage, the vibration kicker magnet on the vibrating arm, the gear train of vibrating arm below constitutes.
Above-mentioned standpipe is the glass standpipe.
The gear train of above-mentioned vibrating arm below is made of the cam, power wheel and the power source that are fixed in the rotating shaft, its power source or for being fixed in the handle on the power wheel, or be the motor through the belt connection.
A kind of magnetic suspension vibrating instrument, it is characterized in that: it is by support plate, the magnetic levitation oscillator in the transparent standpipe of support plate upper fixed, transparent standpipe, the vibrating arm of the band vibration kicker magnet on the support plate is fixed in transparent standpipe below, and the gear train of vibrating arm below constitutes.
Above-mentioned gear train is made of motor, the ratio wheel, the power wheel of strap cam, the rotating shaft that are connected with motor through belt.
The utility model adopts ferromagnetic material, uses the mutually exclusive principle of magnet like poles, utilizes the motor machine transmission, forms the magnetic suspension vibrating system, has realized contactless magnetic levitation forced vibration.This vibration gauge has overcome spring mechanical vibration gauge deficiency in use fully, and it is with property is good frequently, and responsiveness is good, and resonance effect is stable.
