Technical Field

[0002] A flywheel is a key component used to control and regulate the rotation speed and stability of a mechanical system. It usually consists of a rotating disc or wheel that can store and release the kinetic energy of a mechanical system. The moment of inertia of a flywheel refers to its resistance to external torque, which can also be understood as its inertia. Traditional flywheels usually have a fixed moment of inertia, but in some applications, the moment of inertia of the flywheel needs to be adjusted according to actual needs. To achieve this, modern flywheels usually use some advanced technologies, such as adjustable weight blocks, adjustable axial distances, or adjustable material density. These technologies allow the moment of inertia of the flywheel to be adjusted under different working conditions to meet the requirements of the system. By adjusting the moment of inertia of the flywheel, the dynamic characteristics of the mechanical system can be changed, the response speed and stability of the system can be improved, and the vibration and noise of the system can be reduced. Therefore, flywheels with adjustable moment of inertia have been widely used in some high-performance mechanical systems, such as automobile engines, aircraft engines, high-speed trains, etc.

[0037] like Figure 1-Figure 9 A flywheel with adjustable moment of inertia is shown, comprising a flywheel assembly and an adjustment clamping device fixedly connected to the flywheel assembly.
[0038] Reference Figure 8 The flywheel assembly is disassembled along its axial direction, and includes, from top to bottom, a first flywheel sheet 1 and a second flywheel sheet 2 that are slidably connected to each other in an interlaced manner, an upper outer cover 17, a first sliding block 3 and a second sliding block 4 that are slidably connected to the first flywheel sheet 1 and the second flywheel sheet 2 respectively, a groove plate 9 used in conjunction with the first sliding block 3 and the second sliding block 4, a rotating plate 10 fixed to the adjusting clamping device and slidably connected to the first sliding block 3 and the second sliding block 4, a fixed plate 12 slidably connected to the rotating plate 10 and fixed to the adjusting clamping device, and a lower outer cover 18 fixedly connected to the upper outer cover 17 and slidably connected to the rotating plate 12.
[0039] Reference Figure 1-Figure 2 There are six first flywheel pieces 1 and six second flywheel pieces 2, all of which are fan-shaped. The second flywheel piece 2 is provided with a slide groove that is compatible with the first flywheel piece 1. The first flywheel piece 1 is slidably connected with the slide groove of the second flywheel piece 2 along the radial direction. In this way, the first flywheel piece 1 and the second flywheel piece 2 are staggered and connected as a whole to form a circular arrangement.
[0040] The upper outer cover 17 is a cover-shaped circular ring, the circumference of which is bent downward, and the upper outer cover 17 has a plurality of slots circumferentially for fixing and connecting the lower outer cover 18 .
[0041] The first sliding block 3 and the second sliding block 4 are both provided with small holes, through which the first sliding block 3 and the second sliding block 4 are both socketed with guide rails 5, and the first sliding block 3 and the second sliding block 4 are alternately arranged along the circumference on the guide rails 5, through which the sliding blocks are used for sliding, and the rotating disk 10 is provided with guide rail brackets 6 at equal distances along the circumference, the guide rails 5 are inserted into the guide rail brackets 6, and the guide rail brackets 6 are fixed to the rotating disk 10 by cap nuts 7, the guide rails 5, the sliding blocks and the guide rail brackets 6 are in the same radial plane, and there are twelve groups of guide rails 5, sliding blocks and guide rail brackets 6 arranged at equal distances along the circumference.
[0042] The slotted plate 9 is a circular plate, and is fixedly connected to the fixed plate 12 via a double-pass hexagonal copper column 13, and a plurality of sliding grooves corresponding to the sliding blocks are opened on the radial plane thereof.
[0043] Reference Figure 6 A slot is provided on the rotating disk 10, and the lower ends of the first sliding block 3 and the second sliding block 4 are protruding cylinders, which are inserted into the slots of the rotating disk 10 to form a sliding connection. The protruding cylinder slides in the slots of the rotating disk 10 to achieve a sliding connection between the sliding block and the rotating disk 10. There is an opening protrusion at the center of the disk surface of the rotating disk 10, and the center of the guide rail 5 is inserted into the opening protrusion and fixed.
[0044] The rotating disk 10 is provided with a notch 101 close to the center of the circle and a rotating disk chute 15 away from the center of the circle. The width of the notch 101 is slightly larger than the rotating disk chute 15. Three circumferentially arranged positioning cylinders 8 are arranged on the fixed disk 12 at a position relative to the notch 101. A double-pass hexagonal copper column 13 is arranged on the fixed disk 12 at a position relative to the rotating disk chute 15. A hexagon socket bolt 14 is inserted into the double-pass hexagonal copper column 13. The positioning cylinder 8 is adapted to the notch 101, and the double-pass hexagonal copper column 13 is adapted to the rotating disk chute 15 to achieve a sliding connection between the rotating disk 10 and the fixed disk 12. The three circumferential array positioning cylinders 8 cooperate with the notch 101 of the rotating disk 10 to limit the angular range of the rotating disk 10 to 50°.
[0045] The fixed disk 12 is a circular disk, a deep groove ball bearing 11 is placed in a central hole of the fixed disk 12 and the fixed disk 12 is slidably connected to the deep groove ball bearing 11 .
[0046] The lower outer cover 18 has slots on its surface, which are connected to the fixed plate 12 via bolts and nuts. The lower outer cover 18 has slots on its circumference, which are connected to the upper outer cover 17 and are connected to the upper outer cover 17 via bolts and nuts 16.
[0047] Reference Figure 7 and Fig. 9The adjusting clamping device includes a knob 36, an upper regulator bracket 32, a ratchet gear 27, a lower regulator bracket 26, a deep groove ball bearing 24, a gear 23, an arc-shaped rack 22, and a ratchet pawl 34 and a pull-out stem used in conjunction with the ratchet gear 27. The first flywheel piece 1 and the second flywheel piece 2 are used in conjunction with the ratchet gear 27. The upper regulator bracket 32 and the lower regulator bracket 26 are connected by a nut 30, a gasket 31, a sleeve 29, and a hexagon socket nut 28. The inner ring of the deep groove ball bearing 24 cooperates with the lower end of the ratchet gear 27, and the outer ring of the deep groove ball bearing 24 cooperates with the lower end of the ratchet gear 27. The regulator bracket 26 cooperates, the knob 36 and the ratchet gear 27 are connected by a triangular keyway to achieve a fixed connection between them, the ratchet gear 27 and the tooth 23 are linked by a triangular keyway to achieve a fixed connection between them, the gear 23 is meshed with the arc-shaped rack 22, the ratchet gear 27 is located between the upper regulator bracket 32 and the lower regulator bracket 26, and the pawl 34 is installed on the lower regulating bracket 26. By turning the knob 36, the movement of the ratchet gear 27, the gear 23, and the arc-shaped rack 22 is driven, and then the rotation of the rotating disk 10 is driven, thereby realizing the rotation opening and closing of the flywheel.
[0048] A positioning column adapted to the pawl 34 is provided on the end of the lower adjustment bracket 26 away from the hexagonal nut 28, and a torsion spring 35 is mounted on the positioning column. The positioning column is inserted into the retaining ring 33. One end of the torsion spring 35 presses the pawl 34, and the other end presses the lower regulator bracket 26. The pawl 34, the retaining ring 33 and the lever are integrally formed in an S shape.
[0049] Reference Figure 5-Figure 6 The lower regulator bracket 26 is fixedly connected to the lower outer cover 18 and the fixed plate 12 by bolts and nuts. The gear 23 is suspended by installing the sleeve 25 to avoid contact and friction between the gear 23 and the lower outer cover 18. The arc rack 22 is fixedly connected to the rotating plate 10 by the hexagon socket bolts 20, the sleeve 29 and the nut 19.
[0050] The working principle of the flywheel with adjustable moment of inertia is as follows: Figure 6 and Figure 7 As shown, the operation is performed from the back, at which time the connection between the gear 23 and the arc-shaped rack 22 is at the far right end, and the first flywheel 1 and the second flywheel 2 are both in an open state. Fig. 9, by rotating the knob 36 counterclockwise, the knob 36 rotates and drives the ratchet gear 27 to rotate counterclockwise. The cooperation between the ratchet gear 27 and the pawl 34 allows the rotation to move in one direction only, avoiding reverse drive. The ratchet gear 27 drives the gear 23 to rotate counterclockwise, and the gear 23 drives the arc rack 22 to move clockwise along the arc. The arc rack 22 is fixedly connected to the rotating disk 10, so the arc rack 22 drives the rotating disk 10 to rotate counterclockwise. Due to the unique slide groove structure of the rotating disk 10, the rotating disk 10 can only rotate within the required angle range (50°) under the constraint of the fixed disk 12. The rotating disk 10 rotates counterclockwise, driving the guide rail 5 to rotate through the opening protrusion, and the first sliding block 3 and the sliding block 4 connected to the guide rail rotate accordingly. However, under the constraint of the groove disk 9 fixedly connected to the fixed disk 12, the sliding block moves counterclockwise toward the center along the sliding groove track in the groove disk 9. Since the sliding block is fixedly connected to the flywheel piece, the flywheel piece slides toward the center of the circle, thereby realizing the rotation and closing operation of the first flywheel piece 1 and the second flywheel piece 2.
[0051] Conversely, when the knob 36 is rotated clockwise, the first flywheel 1 and the second flywheel 2 can be rotated and opened in the same manner. However, it should be noted that due to the one-way constraint between the ratchet gear 27 and the pawl 34, the pawl 34 needs to be opened to achieve this operation. The one-way constraint between the ratchet gear 27 and the pawl 34 can prevent the centripetal force generated by the flywheel from rotating and driving the knob 36 to rotate in the opposite direction.
[0052] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model rather than to limit it. Although the utility model has been described in detail with reference to the preferred embodiments, ordinary technicians in the field should understand that the technical solution of the utility model can be modified or replaced by equivalents without departing from the purpose and scope of the technical solution, which should be included in the scope of the claims of the utility model.
