Examples

Referring to fig. 1, the present embodiment provides a flywheel 9 stability test stand, which mainly includes a base 1, a detection seat 2, a rotating shaft 3, a driving motor 4, a movable seat 5, a push rod 6 and a buffer mechanism 7.

The detection seat 2 is fixed on the base 1, the rotating shaft 3 is rotationally connected to the detection seat 2, the connecting disc 31 is fixed on the rotating shaft 3, the flywheel 9 is fixed on the rotating shaft 3 through the connecting disc 31, the driving motor 4 is in transmission connection with the rotating shaft 3, the movable seat 5 is movably arranged on the base 1, one end of the ejector rod 6 is connected on the movable seat 5 and is coaxial with the rotating shaft 3, the diameter of the ejector rod 6 is smaller than or equal to the diameter of the rotating shaft 3, after the flywheel 9 is accidentally separated from the rotating shaft 3, the flywheel 9 can move onto the ejector rod 6, and the buffer mechanism 7 can play a buffer role on the flywheel 9 moving onto the ejector rod 6.

When the flywheel 9 is used, the flywheel 9 is fixed on the rotating shaft 3, the movable seat 5 is moved leftwards, the left end of the ejector rod 6 on the movable seat 5 is butted with the rotating shaft 3, the movable seat 5 is fixed at the current position, and then the rotating shaft 3 is rotated through the driving motor 4, so that the stability of the flywheel 9 during rotation is detected. When the flywheel 9 accidentally breaks away from the rotating shaft 3 and moves onto the ejector rod 6, the flywheel 9 rotates under the action of inertia and moves rightwards along the ejector rod 6, and under the action of the buffer mechanism 7, the flywheel 9 can be buffered, so that the flywheel 9 finally stops moving.

When an accident occurs, the flywheel 9 is separated from the rotating shaft 3, but the flywheel 9 is transferred to the ejector rod 6, the flywheel 9 can be supported by the ejector rod 6, and compared with the flywheel 9 which flies directly from the rotating shaft 3 and falls down randomly, the flywheel 9 has smaller right-moving kinetic energy, so that the flywheel 9 can stop moving more easily under the action of the buffer mechanism 7.

The main components and principles of the flywheel 9 stability test stand are generally described above, and the flywheel 9 stability test stand will be described in more detail below.

The damping mechanism 7 may mainly comprise a cross bar 71, a stationary ring 72 and a damping spring 73. The cross rod 71 is inserted into the movable seat 5 and can move transversely, the fixed ring 72 is fixed at the left part of the cross rod 71, the buffer spring 73 is sleeved on the cross rod 71, one end of the buffer spring 73 is connected with the fixed ring 72, and the other end is connected with the movable seat 5. When the cross bar 71 moves rightward under the impact of the flywheel 9, the buffer spring 73 can alleviate the impact from the flywheel 9 received by the cross bar 71, and stop the movement of the flywheel 9 finally.

In order to prevent the cross bar 71 from being separated from the movable seat 5 when being reset in a left-moving way, an anti-falling block 74 is fixed on the cross bar 71, and the anti-falling block 74 is positioned on the right side of the movable seat 5.

The end of the cross bar 71 facing the detection seat 2 is fixed with a buffer head 75 made of rubber, and the buffer head 75 not only can slow down the impact force of the flywheel 9 on the cross bar 71 when moving rightwards, but also can increase the friction resistance of the flywheel 9 in the rotating process, which is helpful for stopping the rotation and movement of the flywheel 9 rapidly.

It should be noted that, the number of the cross bars 71 is not limited in this embodiment, and the number of the cross bars 71 may be one or more, and when there are a plurality of cross bars 71, the material requirement for a single cross bar 71 is low.

The ejector rod 6 has a connecting portion 61 towards one end of the rotating shaft 3, and the connecting portion 61 is inserted into one end of the rotating shaft 3, so that the ejector rod 6 and the rotating shaft 3 can together support the flywheel 9, that is, the flywheel 9 can be well supported no matter whether the flywheel 9 is on the rotating shaft 3 or the ejector rod 6.

It should be noted that, the connection mode of the ejector rod 6 and the movable seat 5 may be either a fixed connection mode or a rotational connection mode, which is not limited in this embodiment. When the ejector rod 6 is fixedly connected with the movable seat 5, in order to ensure the normal rotation of the rotating shaft 3, the cross section of the connecting part 61 is circular, and the connecting part 61 can rotate relative to the rotating shaft 3.

In order to facilitate the push rod 6 to be close to or far away from the rotating shaft 3, a transverse moving cylinder 8 for moving the movable seat 5 leftwards or rightwards is arranged on the detection seat 2, a guide rail 11 is arranged on the base 1, the bottom of the movable seat 5 is in sliding connection with the guide rail 11, and the movement of the push rod 6 is realized by moving the movable seat 5 leftwards or rightwards, when the push rod 6 moves rightwards, the distance between the push rod 6 and the rotating shaft 3 is increased, so that the flywheel 9 is conveniently fixed on the rotating shaft 3; when the ejector rod 6 moves leftwards and contacts with the rotating shaft 3, the flywheel 9 can be smoothly transferred to the ejector rod 6 conveniently when accidents occur.

Finally, it should be noted that: the above is only a preferred embodiment of the present utility model, and it is not intended to limit the present utility model, and various modifications and variations of the present utility model may be possible to those skilled in the art, and the embodiments of the present utility model and features in the embodiments may be arbitrarily combined with each other without collision. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present utility model should be included in the protection scope of the present utility model.
