Abstract
A flywheel experimental instrument with a variable moment of inertia belongs to the technical field of experiment equipment. The flywheel experimental instrument with the variable moment of inertia comprises a control box, a motor, a flywheel, a pedestal, slide blocks and slide bars. The control box and the motor are installed on the pedestal. The flywheel is installed on the motor. The slide bars in a vertically intersecting mode are installed on the flywheel. The slide blocks are installed on the slide bars. The experimental instrument can change mass distribution of the flywheel so as to change the moment of inertia of the whole flywheel. Through measuring and determination of influences on machine rotation stability by different moment of inertias of the flywheel, students have further understanding about flywheel experiments; content of the experimental instrument is increased; and knowledge of the students is enriched.
Description
Technical field
The utility model relates to the variable flywheel experiment instrument of moment of inertia, belongs to experimental facilities technical field.
Background technology
Flywheel experiment is a model experiment of mechanical major, contribute to student to the understanding in depth of mechanical principle, but its function singleness is not given full play to its experiment Teaching Value, just done the inertia experiment of rotation at present, relatively wasting experimental resources, is a urgent problem.
Summary of the invention
The purpose of this utility model is to provide the variable flywheel experiment instrument of moment of inertia.
Problem to be solved in the utility model is the deficiency of existing flywheel experimental facilities function singleness.
The flywheel experiment instrument that moment of inertia is variable, comprises control box, motor, flywheel, base, slide block and slide bar, and control box, motor are installed on described base, and flywheel is installed on motor, and the slide bar of square crossing is installed on flywheel, and slide block is installed on slide bar.
On described slide block, lock screw is installed.
Described flywheel is cast iron materials.
Described control box is frequency-variable controller.
Advantage of the present utility model: this experiment instrument is provided with adjustable slide block on flywheel, can change the mass distribution of flywheel, thereby changes the moment of inertia of whole flywheel.By measure different moment of inertia flywheels to machine turns stability be used for allow student have one further to understand to flywheel experiment, should there is the wide market space.
Brief description of the drawings
Fig. 1 is the structural representation of the variable flywheel experiment instrument of the utility model moment of inertia;
Fig. 2 is the side schematic view of flywheel;
In figure: 1, control box 2, motor 3, flywheel 4, base 5, slide block 6, slide bar.
Embodiment
Below in conjunction with drawings and Examples, the utility model is further described.
The flywheel experiment instrument that moment of inertia is variable, comprise control box 1, motor 2, flywheel 3, base 4, slide block 5 and slide bar 6, control box 1, motor 2 are installed on described base 4, flywheel 3 is installed on motor 2, the slide bar 6 that square crossing is installed on flywheel 3, is provided with slide block 5 on slide bar 6.
On described slide block 5, lock screw is installed.
Described flywheel 3 is cast iron materials.
Described control box 1 is frequency-variable controller, can regulate easily the rotating speed of flywheel 3.
Using method of the present utility model: open motor 2 by control box 1, motor 2 flywheel drivens 3 rotate, measure the effect of different moment of inertia flywheels 3 to machine turns stability by adjusting slider 5 at the diverse location of slide bar 6, also can study the stability under different rotating speeds, increase the content of this experiment instrument, also enriched student's knowledge.
