It should be understood that the specific embodiments described herein are merely illustrative of the utility model and are not intended to limit the utility model.
The flywheel with the adjustable moment of inertia is applied to the spinning.

Five positioning rods 14 are uniformly arranged on the circumferential surface 11 of the flywheel in an annular array by taking the flywheel main shaft 13 as a central point.
The two rotational inertia adjusting units 20 are symmetrically arranged on both sides of the flywheel main body 10 with the flywheel main body 10 as a center plane. The two inertia moment adjusting units 20 have the same structure and connection relationship, and one of them is described in detail below as an example.
The inertia moment adjusting unit 20 includes a wire coil 21, five inertia moment adjusting modules, and a torsion coil 30. The five rotational inertia adjusting modules are respectively arranged on the five positioning rods 14 in a one-to-one correspondence manner. The structures and the connection relations of the five rotational inertia adjusting modules are the same, and one of the rotational inertia adjusting modules is taken as an example to be explained in detail below.
The rotational inertia adjusting module comprises a guide rail 22, a balancing weight 23, a hanging seat 24, a first tension spring 25, a limiting rod 26, a pull rope 27, a limiting rod seat 28 and a second tension spring 29.
The wire coil 21 is sleeved on the flywheel main shaft 13. All be provided with the fixing base on the position that corresponds with five inertia adjusting module on drum 21.
The guide rail 22 is provided on the positioning rod 14. The weight 23 is engaged with the guide rail 22 and can slide back and forth along the guide rail 22.
The lower end of the hanging seat 24 is provided with a groove, and one end of the guide rail 22 passes through the groove to be connected with the wire coil 21. The hanging seat 23 is fixed on the guide rail 22. One end of the hanging seat 24 is in contact with the wire coil 21.
The first tension spring 25 is arranged between the hanging seat 24 and the balancing weight 23, and two ends of the first tension spring are respectively connected with the other end of the hanging seat 24 and one end of the balancing weight 23.
The stop bar 26 is an inverted T-bar. The horizontal bar of the inverted T-bar is parallel to the guide rail 22 and above the guide rail 22, and the vertical bar is perpendicular to the horizontal bar and is arranged in the middle of the horizontal bar.
The pull rope 27 is a flexible pull rope, and two ends of the pull rope are respectively connected with the fixing seat on the wire coil 21 and the vertical rod of the limiting rod 26.
The lower end of the stopper rod seat 28 is provided with a groove, and the other end of the guide rail 22 passes through the groove at the lower end of the stopper rod seat 28. The stopper rod seat 28 is also provided with a head through hole which is located above the groove.
One end of the horizontal rod of the limiting rod 26 is fixedly connected with the other end of the balancing weight 23; the other end of the spring passes through a through hole on the stop lever seat 28 and can do telescopic motion in the through hole under the action of the pull rope 27 and the balancing weight 23.
The second tension spring 29 is located between the limiting rod 26 and the limiting rod seat 28, and two ends of the second tension spring are respectively connected with the vertical rod of the limiting rod 26 and the limiting rod seat 28.
The two housings 40 are respectively disposed outside the two inertia moment adjustment units 20. The two housings 40 are identical in structure and connection, and one of them will be described in detail.
A through-hole 41 is provided at the center of the outer cover 40. The outer cover 40 is sleeved on the flywheel main shaft 13 through the through hole 41. The edge of the outer cover 40 is connected to the outer race 12 of the flywheel main body 10 by screws. Inertia graduated scales 42 which are annularly distributed along the through hole are arranged on the outer cover 40 and are positioned around the through hole, and the inertia graduated scales 42 can be used for marking the rotation inertia value of the flywheel.
The torsion disc 30 is sleeved on the flywheel main shaft 13 and is positioned outside the outer cover 40. The twisting disk 30 is provided with a positioning mark 31. The positioning mark 31 is an arrow mark. When the twisting disc 30 is fixed outside the outer cover 40, the positioning mark 31 points to the inertia scale 42 and corresponds to a certain scale on the inertia scale 42 to indicate the current maximum rotation inertia value of the flywheel.
After the rotational inertia adjusting unit 20 and the outer cover 40 are respectively and symmetrically sleeved on two sides of the flywheel main shaft 13, the torsion disc 30 is sleeved on the flywheel main shaft 13 outside the outer cover 40, and then the fixing nut 50 is screwed on the torsion disc 30, so that the outer cover 40 and the rotational inertia adjusting unit 20 are fixed on the flywheel main shaft 13.
After the flywheel rotates, the counterweight 23 receives centrifugal force and the pulling force of the first tension spring 25, and the two forces are opposite in direction (the centrifugal force is towards the outer ring 12, and the pulling force is towards the flywheel spindle 13). When the speed of the flywheel is gradually increased and the centrifugal force applied to the weight block 23 is increased to be larger than the pulling force of the first tension spring 25, the weight block 23 moves away from the center of the flywheel spindle 13 along the guide rail, so that the rotational inertia of the whole flywheel is increased. The eccentric movement of the weight 23 pushes one end of the horizontal rod of the limiting rod 26 to move towards the through hole of the limiting rod seat 28, thereby compressing the second tension spring 29.
If the moment of inertia of the flywheel is defined as: when the wire coil 21 rotates clockwise, the pull rope 27 is tightened, and one end of the horizontal rod of the limiting rod 26 moves away from the through hole of the limiting rod seat 28 (towards the flywheel main shaft 13), and at the moment, the moment of inertia becomes smaller. Conversely, when the wire coil 21 rotates counterclockwise, the pull rope 27 is loosened, and one end of the horizontal rod of the stopper rod 26 moves toward the through hole of the stopper rod holder 28 (away from the flywheel spindle 13), so that the moment of inertia increases. The pulling rope 27 is a flexible rope which is always tensioned by the force of the second tension spring 29.
The maximum moment of inertia generated when the flywheel rotates can be adjusted by the wire coil 21, the pull rope 27 and the limiting rod 26, and the adjustment is realized by adjusting the distance between the wire coil 21 and the vertical rod on the limiting rod 26, namely the length of the pull rope 27 between the wire coil 21 and the vertical rod.
In addition, since the stopper rod 26 is always pulled by the second tension spring 29, it is necessary to fix the wire coil 21 by the fixing nut 50 after the adjustment. If the wire coil 21 is not fixed after adjustment, the wire coil 21 will rotate to return to the original position (the state position where the second tension spring 29 is not pulled), i.e. the function of adjusting the maximum moment of inertia cannot be achieved. Therefore, a fixing nut is required to be added to fix the position of the adjusted wire coil 21.
According to the flywheel with adjustable rotational inertia in the above embodiment, the flywheel main body includes the flywheel main shaft, the rotational inertia adjusting unit is disposed on the flywheel main body, and the outer cover is disposed outside the rotational inertia adjusting unit.
