Abstract
The invention relates to an angle-displacement mechanical oscillator which can be widely used for physics experiment demonstration in university and middle school. On the rotating shaft of a motor is fitted with an eccentric rotary wheel which is connected with a slide link. The slide link is connected with a crank which is connected with a rotating shaft which is fitted on a base plate for fixing the motor and the eccentric rotary wheel. When the motor rotates, the eccentric wheel elliptically rotates to drive the slide link and the crank to make the rotating shaft produce an angle-displacement reciprocating movement. As the rotating speed of the motor can be regulated continuously, the oscillation frequency of the angle-displacement mechanical oscillator can be regulated continuously in a wide frequency range.
Description
Technical field
The present invention relates to a kind of angular displacement mechanical oscillator, can be widely used in the big middle school physical experiment demonstration, all use as physics demonstrations such as figure such as optical scanning, Li Sa to obtain angular displacement mechanical oscillator.
Background technology
At present, in big physical experiment teaching in middle schools, physics demonstration is indispensable laboratory facilities, and the mechanical vibration part is occupied the proportion of outbalance in physics demonstration experiment.Prior art is an a kind of scanning swing motor (English name is scaner), is the axial deflection swing, the swing deflection angle is to the maximum ± and 30 °.Its principle of work as shown in Figure 4, permanent magnet rotor 15 is because the effect of magnetic field force own is equilibrated at the equilibrium position between two soft iron pole shoes 14 (stator).When the coil in the two soft iron pole shoes 13 passes through exchange current, between two soft irons, produce an alternating magnetic field immediately, under the effect of this magnetic field force, be subjected to ordering about of this power to place therebetween rotor 15 to leave the equilibrium position produces reciprocal deflection and swings thereupon, its frequency is consistent with the exchange current in the coil, and its deflection amplitude of oscillation depends on the size of magnetic field force that electric current produces.
Existing oscillator cost height, demonstration effect simply can not satisfy the various requirement of big middle school Physical Experiment Course demonstration effect.
Summary of the invention
The objective of the invention is to, provide a kind of simple, cost is low, demonstration outstanding effect angular displacement mechanical oscillator.
Structural principle of the present invention is that rotatablely moving of motor is converted to the angular displacement reciprocally swinging, its technical scheme is shown in structural representation Fig. 1,2, this angular displacement mechanical oscillator is device one an eccentric runner 3 on the turning axle of motor, eccentric runner 3 is connected with slide link 6, slide link 64 is connected with cranking arm, cranking arm 4 connects a rotating shaft 2, and rotating shaft 2 is arranged on the base plate 1 that is used for fixing motor and eccentric runner 3; When motor 7 rotated, eccentric runner 3 was done oval the rotation, and drove slide link 6 and crank arm 4, made it produce the reciprocally swinging of angular displacement in rotating shaft 2, rotatablely moving of motor was converted to the reciprocally swinging of angular displacement.
The motor that uses in the described angular displacement mechanical oscillator can be selected direct current generator for use, between eccentric runner 3 and the slide link 6, slide link 6 and cranking arm between 4, can adopt bearing to connect.
Because the rotating speed of direct current generator is adjustable continuously, the vibration frequency of this angular displacement mechanical oscillator is also adjustable continuously at the frequency separation of broad thereupon, can make the vibration frequency interval of angular displacement mechanical oscillator that favorable linearity and response are arranged, its deflection angle displacement is ± 10 °, vibration frequency 0-140Hz..
The difference of this angular displacement mechanical oscillator provided by the invention and prior art maximum is: prior art is a kind of axial wobble motor, and the present invention changes the rotation of motor into angular displacement deflection vibration by physical construction, driving circuit of the prior art is comparatively complicated, and driving circuit of the present invention is comparatively simplified, and only needing to adjust direct supply can pilot angle displacement deflection vibration frequency.Therefore cost is low, and the demonstration effect is obvious, thereby motivates students' interest in learning, and strengthens the appeal of physics demonstration experiment.
