Rotational inertia-adjustable flywheel

Technical Field

The invention relates to a flywheel, in particular to an adjustable moment of inertia of the flywheel.

Background Art

The flywheel is mounted on the engine crankshaft having a relatively large moment of inertia on the accumulator, when the engine speed increases, an increase of the kinetic energy of the flywheel, to store the energy; when the engine rotational speed is reduced, reducing the kinetic energy of the flywheel, the energy is released, can be used for reducing the speed of mechanical operation process fluctuations, overcome the resistance of the other stroke, uniform rotation of the crankshaft.

The greater the rotational inertia of the flywheel, the stronger its energy storage capacity, is smooth running of the engine, but the starting or speed-change during the process needs to consume more energy to overcome is used to energy of the flywheel, the flexibility of the engine is reduced.

In the prior art, the thickened outer periphery of the flywheel disc structure, in order to increase its moment of inertia as much as possible. But, this structure forms the rotating inertia of the flywheel is constant, have restricted its convenience of use.

Content of the invention

The purpose of this invention is to, provide a rotating moment of inertia can be adjusted according to the needs of the flywheel.

To achieve the above-mentioned purposes of the present invention adopts the technical scheme that, with a rotating inertia of the flywheel, including the fly wheel disk and so as to form interference fit is the gear ring of the fly wheel; characterized in that it also comprises a lead screw, a sliding block, a connecting rod, a connecting sleeve;

Said fly wheel on the one side surface, the radial direction along the circumference is uniformly provided with a plurality of strip-shaped and not penetrating the chute;

For a number of the number of the sliding block, are respectively one-to-one correspondence in is installed in the sliding slot, the sliding block and a sliding connection between the chute;

The screw rod is welded in the center of the surface of the chute;

The outer side of the connecting sleeve is provided with a plurality of evenly on the outer wall of the connection device of the articulated shaft, on the inner wall of the connecting sleeve is provided with an inner thread, of the connecting sleeve in the assembly by a screw thread on the screw;

Number is a number of said connecting rod, one end of each connecting rod and its corresponding are respectively hinged at hinge shaft coupling device, and the other ends are respectively hinged with its corresponding slide block.

The above-mentioned technical scheme is directly bringing the technical effects, of the flywheel in the form of the above-mentioned structure, when the slide block in position close to the center of the flywheel, the moment of inertia is relatively small, the sliding block is in the position away from the center of the flywheel disc, a relatively large moment of inertia.

In other words, through a connecting sleeve, a lead screw, a connecting rod, part of the chute and the adjusting device, can be flexibly and conveniently adjusting the rotational inertia of the flywheel.

That is to say, the above-mentioned structure can be realized in the form of tappets of the flywheel.

Preferably, the above-mentioned inertia adjustable flywheel, also comprises a locking nut and locking washer; the states stops draws back washer is sleeved on the upper part of the of the connecting sleeve; the gasket states stops draws back through the locking nut in the locking of the connecting sleeve on the screw.

The preferred technical scheme is directly technical effect, can be guaranteed in the course of high-speed rotation of the flywheel, the connecting sleeve will not deviate from its reference position, moving to the top, so as to cause rotation of flywheel inertia variation.

Further preferably, the above-mentioned groove, the slide block, the hinge shaft is connected with the device and the number of the connecting rods are six or eight. .

The preferred technical scheme has a direct technical effect is, that in practical application, the number of slide block, six or eight normal circumstances the actual application needs can be satisfied, and space convenient layout, reasonable, processing the difficulty level and the processing cost is relatively ideal.

Further preferably, the above-mentioned slider is greater than the density of the density of the said fly wheel.

The preferred technical scheme is directly technical effect, can further ensures that the slide block is to the position change, increase the range of adjustment of the moment of inertia of the flywheel.

To sum up, the present invention compared with the prior art, has the following beneficial effects:

1, can be regulated freely rotating inertia, the "multi-purpose";

2, the meet the above-mentioned 1 under the condition of, the overall structure is simple, manufacturing is simple and the cost is low.

Mode of execution

In conjuction with the following, detailed description of this invention.

As shown in Figure 1 to 3 is shown, the invention of the moment of inertia of the flywheel, which comprises a flywheel disk 1 and so as to form interference fit is the gear ring of the fly wheel 2 ; characterized in that it also comprises a lead screw 3, the slide block 4, connecting rod 5, the connecting sleeve 6;

The above-mentioned flywheel on a side surface, the radial direction along the circumference is uniformly provided with a plurality of strip-shaped and not penetrating the chute 7;

The above-mentioned slide block 4 for a number of the number, are arranged in one-to-one correspondence of the above-mentioned groove 7 in, the above-mentioned slide block 4 and the above-mentioned groove 7 into the slidable connection between the;

The above-mentioned lead screw 6 to weld on the above-mentioned flywheel disk facing away from the crankshaft direction of the surface of one side of the center position;

The above-mentioned connecting sleeve at the outer side of the articulated shaft is provided with a plurality of evenly on the outer wall of the connection device 8, the above-mentioned of the connecting sleeve is provided with an inner thread on the inner wall, the connecting sleeve is 6 through threaded mounting in the above-mentioned screw 3 is; the above-mentioned connecting rod 5 in the number of a number of, each connecting rod 5 are respectively hinged at one end of the hinge shaft with the corresponding coupling device 8 on, respectively and the other end of the corresponding slide block 4 is hinged.

The above-mentioned inertia adjustable flywheel, preferably also includes a locking nut (not shown in the Figure) and a check washer (not shown in the Figure); the above-mentioned retaining washer is sleeved on the upper part of the connecting sleeve, and through the above-mentioned locking nut will be the connecting sleeve is locked in the above-mentioned screw 3 is. In this way, can be effectively avoided during high speed rotation of the flywheel, the connecting sleeve 6 will not deviate from its reference position, moving to the top, so as to cause rotation of flywheel inertia variation.

The above-mentioned groove 7, the slide block 4, hinge axis connection device 8 and the connecting rod 5 is the number of six or eight.

The above-mentioned slide block 4 preferably uses copper, lead or copper-lead alloy with large density, such as metal, in order to guarantee its density greater than steel flywheel 1 density. In this way, can further ensures that the slide block is to the position change, increase the range of adjustment of the moment of inertia of the flywheel.
