Abstract
The utility model relates to a linear displacement mechanical oscillator which can be extensively applied in physical experiment and demonstration in colleges and middle schools. Wherein, an eccentric rotating wheel (5) is arranged on a rotary shaft of a motor and then is connected with a crank arm (6); the crank arm (6) is connected with a sliding bar (3); the sliding bar (3) is positioned with a sliding support (2) on the bottom plate (1) which fixing the eccentric rotating wheel (3) and the motor (7). When the motor (7) rotates, the eccentric rotating wheel (5) can do elliptic rotation and drive the crank arm (6) and the sliding bar (3) for the periodic reciprocal vibration. Because the rotation speed of a DC motor can be steplessly adjusted, the vibration frequency of the linear displacement mechanical oscillator can be adjusted continuously in wide frequency range. The linear displacement mechanical oscillator has advantages of low manufacturing cost and obvious demonstrating effect, so that the learning interest of students can be excavated and the fascination of physical experiment demonstration can be promoted.
Description
Technical field
The present invention relates to a kind of linear displacement mechanical oscillator, can be widely used in the big middle school physical experiment demonstration, all need use linear displacement mechanical oscillator such as physics demonstrations such as standing wave, resonance, ripples dishes.
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.But existing linear displacement mechanical oscillator cost height, the demonstration effect is simple, 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 linear displacement mechanical oscillator.
Structural principle of the present invention is that rotatablely moving of motor is converted to linear vibration, its technical scheme is shown in structural representation Fig. 1,2, this linear displacement mechanical oscillator, it is device one eccentric runner 5 on the turning axle of motor, eccentric runner 5 is connected with curved arm rod 6, curved arm rod 6 is connected with slide link 3, and slide link 3 is set on the base plate 1 that is used for fixing motor 7 and eccentric runner 3 by sliding support 2; When motor 7 rotated, eccentric runner 5 was made the double vibrations that oval rotation and drive curved arm rod 6 and slide link 3 go round and begin again its generation.
The motor that uses in the described linear displacement mechanical oscillator can be selected direct current generator for use, between eccentric runner 5 and the curved arm rod 6, between curved arm rod 6 and the slide link 3, can adopt bearing to connect.
Because the rotating speed of direct current generator is adjustable continuously, the vibration frequency of this linear displacement mechanical oscillator is also adjustable continuously at the frequency separation of broad thereupon, can make linear displacement mechanical oscillator in the vibration frequency interval favorable linearity and response be arranged.Its vibration-type linear displacement is ± 4mm vibration frequency 0-140Hz..
This linear displacement mechanical oscillator provided by the invention, cost is low, and the demonstration effect is obvious, thereby motivates students' interest in learning, and strengthens the appeal of physics demonstration experiment.
