Abstract
The utility model relates to a linear displacement mechanical oscillator, which can be widely used in the physical lecture experiment in large secondary school. The linear displacement mechanical oscillator is provided with an eccentric rotating wheel (5) on a rotating axle of a motor, the eccentric rotating wheel (5) is connected with one end of a crank arm connecting rod (6), the other end of the crank arm connecting rod (6) is connected with one end of a sliding connecting rod (3), and the sliding connecting rod (3) is arranged on a base plate (1) used for fixing a motor (7) and the eccentric rotating wheel (5) through a sliding supporting frame (2); when the motor (7) rotates, the eccentric rotating wheel (5) rotates in an oval-shaped type and drives the crank arm connecting rod (6) and the sliding connecting rod (3) to generate circular reciprocating vibration. Because the rotating speed of the direct current motor can be continuously adjustable, the vibration frequency of the linear displacement mechanical oscillator can also be continuously adjustable within wider frequency interval. The linear displacement mechanical oscillator provided by the utility model has the advantages of low fabrication cost and obvious demonstration effect, thus stimulating the learning interests of students, and enhancing the appeal of the physical lecture experiment.
Description
Technical field
The utility model 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.
The utility model content
The purpose of this utility model is, provides a kind of simple, and cost is low, demonstration outstanding effect linear displacement mechanical oscillator.
Structural principle of the present utility model 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 on the turning axle of motor, eccentric runner is connected with an end of curved arm rod, the other end of curved arm rod is connected with an end of slide link, and slide link is set on the base plate that is used for fixing motor and eccentric runner by sliding support; When motor rotated, eccentric runner was made the double vibrations that oval rotation and drive curved arm rod and slide link 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 and the curved arm rod, between curved arm rod and the slide link, 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 that the utility model provides, cost is low, and the demonstration effect is obvious, thereby motivates students' interest in learning, and strengthens the appeal of physics demonstration experiment.
