Variable-inertia spring flywheel capable of automatically regulating rotational inertia

Abstract

The invention discloses a variable-inertia spring flywheel capable of automatically regulating the rotational inertia. The variable-inertia spring flywheel comprises a flywheel shaft, a fixed disc, flywheel plates and a connecting spring; the fixed disc is coaxially and fixedly connected with the flywheel shaft; at least two flywheel plates are uniformly distributed in the circumferential direction of the fixed disc; the flywheel plates are slidably connected with the fixed disc in the radial direction; and the two ends of the connecting spring are correspondingly fixedly connected with the adjacent flywheel plates. The flywheel disclosed by the invention is simple to mount, dismount and transfer; when at a low speed, the flywheel plates are difficult to move out due to limitation of the connecting spring so as to maintain a relatively low rotational inertia; when at a high speed, the flywheel plates move out because the limitation of the connecting spring is overcame by the centrifugal force so as to obtain a relatively high rotational inertia; the flywheel has the characteristics of small start force and high energy storage; each independently moving flywheel can realize automatic regulation by automatically sensing the quality unevenness of the flywheel and the torque fluctuation of an input end and an output end, and thus abnormal vibration and torque fluctuation are reduced.

Description

technical field [0001] The invention belongs to the technical field of energy storage machinery, and specifically relates to a variable inertia spring flywheel with simple structure, small starting force, strong energy storage, self-correction, and ability to reduce torque fluctuations and automatically adjust the moment of inertia. Background technique [0002] The flywheel is a disc-shaped part with a large moment of inertia. Its function is to store a part of the energy generated when the power machinery such as the engine and the press does work, so as to overcome the resistance of other auxiliary strokes or bear the working load. , to make the crankshaft rotate evenly or reduce the output power of the power machinery, which acts as an energy storage. The ability of the flywheel as an energy storage is generally represented by the moment of inertia. The larger the moment of inertia, the more energy storage, but a larger moment of inertia will make it difficult for the po...

AI Technical Summary

Problems solved by technology

Although the use of dual-mass flywheels in the prior art can solve the problem of torque fluctuations, there are also cams and auxiliary structures that require non-circular profiles, which are complex in structure, high in cost, and relatively low in reliability.
