Embodiment
Below in conjunction with drawings and Examples the utility model is further described.
As shown in Figure 1, 2.
A kind of wind-driven generator rotary inertia self-adapting type flywheel gear, it comprises a firm housing 6(profile as shown in Figure 2, housing 6 can be an overall structure with wheel rim 2 also during concrete enforcement) and be installed in wheel hub 1 and wheel rim 2 in the housing 6, wheel hub 1 is installed on the rotor shaft, be evenly equipped with at least two between wheel hub 1 and the wheel rim 2 and (also can select three as required when specifically implementing, four, five, six or with root) spoke 3, one end of spoke 3 links to each other with wheel hub 1, the other end links to each other with wheel rim 2, wheel hub 2 connects into an overall structure with spoke 3 by uniform spoke 3, being equipped with on spoke 3 can be along the slide block 4 of spoke 3 slips and the Returnning spring 5 of slide block 4 being pushed to wheel hub 1, in general, one end of Returnning spring 5 offsets with slide block 4 or links to each other, the other end supports or is fixed on the inwall or the step surface on the spoke 3 of wheel rim 2, as shown in Figure 1.In order to make flywheel keep balance, also can be slide block 4 when specifically implementing and install balancing weight additional, balancing weight can pass through fixed structure forms such as screw thread, dovetail groove and link to each other with slide block.
During concrete enforcement, spoke 3 can integral body be guide rail structure, at this moment, only needs slide block 4 is sleeved on the described spoke 3.
During concrete enforcement, spoke 3 can be shaped simultaneously with wheel hub 1, wheel rim 1, and on described spoke 3 mounting guide rail again, slide block 4 is installed on the described guide rail and offsets with an end of Returnning spring.
Structures such as during concrete enforcement, that the shape of slide block 4 can be is square, cylindricality, sphere, billiard table shape or taper type.
When wind wheel does not change or during the slow-speed of revolution, under the effect of spring, each block concentrates on the center of rotation place, flywheel is an integral body, and center of gravity also is positioned at the place, axle center, and this moment, the rotary inertia of flywheel was little, and the little wind-force that does not influence wind wheel substantially starts.When wind-force becomes big, during faster rotational speed, each block is drawn to the edge of flywheel body under action of centrifugal force and is moved, center of gravity is shifted to the edge, this moment, the rotary inertia of flywheel became big, and the part of wind wheel rotation function will be stored in each block, stored with the kinetic energy form of each block.Because each block is away from the axle center, thereby under the identical situation of angular velocity, its linear velocity means that than big when shaft core position the ability of flywheel stored energy strengthens.Otherwise wind-force diminishes, and the kinetic energy of each block of flywheel will discharge, and promotes wind wheel and be rotated further under effect of inertia, promptly stops the quick downward trend of rotating speed of wind wheel.When wind-force continues to reduce or disappear, when each block of flywheel has discharged kinetic energy, wind speed round will reduce until stopping, and each block of flywheel returns to position, former axle center again under the effect of Returnning spring.
During static the or slow-speed of revolution (state A), the center of flywheel concentrates near the axle center when flywheel, this moment rotary inertia little (shown in Figure 3), the ability of stored energy is little, that is to say that being easy to little moment starts.When the flywheel high speed rotating, from the edge slippage of trend flywheel, this moment, gravity centre distribution arrived the edge of flywheel to each block under action of centrifugal force, and the rotary inertia of flywheel increases, and as shown in Figure 4, the ability of stored energy is strengthened.
The utility model does not relate to the part prior art that maybe can adopt all same as the prior art to be realized.
