Description
Technical field
The present invention relates to a kind of cyclic gear train type inertia variable fly wheel, belong to flywheel technology field.
Technical background
Flywheel energy storage is an ancient thought.In many energy storage modes, such as chemical energy storage, hot energy storage, Power Flow and mechanical energy storage, the simplest in the way of flywheel stores mechanical energy.Since the nineties in 20th century, due to high tensile strength fibrous material, the development of the aspects such as low-loss magnetic bearing and power electronics, flywheel energy storage obtains the great attention of countries in the world.But the research about flywheel technology at present is substantially that existing flywheel can not meet the requirement fast-changing to its rotary inertia of above-mentioned vibrational system around how improving the expansion of its energy density.If applying the present invention in hydraulic shock excitation system, excitation system needs the rotary inertia of flywheel to change by fast periodic, is connected with adding speed motor its one end, and the other end is connected with the actuator exciting of hydraulic vibration exciter by four-bar mechanism.After first variable flywheel is accelerated to certain speed by control motor, motor is disconnected, opens hydraulic shock excitation system, make hydraulic cylinder with producing momentum circulation between variable flywheel, help hydraulic cylinder to realize the work process accelerated and slow down, reduce because throttle grverning shape vibrates the energy lost.This method is the process that energy converts actually, more energy-conservation than existing throttle grverning type hydraulic shock excitation system.
Summary of the invention
The present invention seeks to provide a kind of cyclic gear train type inertia variable fly wheel for above-mentioned weak point, be that a kind of rotary inertia can take turns energy storage equipment by flywheel quick, periodically variable, solve energy storage problem in hydraulic vibration power-saving technology.

After flywheel installation, accelerate driven by motor flywheel head shaft to rotate thus flywheel driven rotation, rotation along with flywheel, eccentric rotating disk main shaft is along with rotation, engagement due to gear wheel fixing on little gear and frame, form relative motion between eccentric rotating disk and flywheel, be also the formation of the cyclic train that we often say.In motor process, the barycenter of eccentric rotating disk changes with the distance generating period of flywheel head shaft 3.By can be calculated, there is one-to-one relationship, i.e. in the rotary inertia J and angle of eccentricity θ of flywheel
Cyclic gear train type inertia variable fly wheel feature of the present invention:
1, flywheel head shaft rotary inertia is cyclically-varying with the rotation of rotating disk, and the change of main axis inertia is to be determined by the gear ratio of meshing gear.Because flywheel head shaft rotating speed is relatively easy to improve, therefore main axis inertia is capable of Rapid Variable Design.
2, in flywheel running, gear be engaged with the highest transmission efficiency, and revolute pair is reduced friction by bearing, so needing the energy of loss the least in motor process.
