Specific embodiment
As shown in the picture, all equal structures of component are simple, reliable, easy to assembly in figure.
Flywheel quantity used can be not limited to three flywheels, can increase in shaft 4 according to actual needs different
The flywheel of rotary inertia, the utility model, which designs, only illustrates its working principle by taking three flywheels as an example.
The specific embodiment of the loacting test rack inertia variable fly wheel system is as follows:
The both ends of shaft 4 are supported on bearing block by two bearings 71 and 72 respectively.Reeded crane on two curb girders
Bracket 8 is placed on hold-down support.Limit plate 95 is mounted on vehicle frame plate 93 by two bolts 96.Crane 9 passes through 4 pin shafts 97
It is supported on 4 wheels 91, the rolling bearing inner ring in 4 wheels 91 is all made of interference fit with 4 pin shafts 97 respectively and connects
It connects.
When operating condition of test needs fly wheel system to provide small rotary inertia, only the second flywheel 2 is rotated with shaft 4,
First flywheel 1 and third flywheel 3 are stored in flywheel storing seat 1, on flywheel storing seat 2 62 respectively.
When operating condition of test needs fly wheel system to increase rotary inertia, only connected with third flywheel 3 and the cooperation of the second flywheel 2
It connects, is illustrated for rotating the two together, the rest may be inferred by analogy.In loacting test rack stationary state, by hanging ring 91 and
The lifting eye 32 of three flywheels 3 cooperates with suspension hook 92 again after being connected through a screw thread；Nut 94 is rotated clockwise, suspension hook 92 slings third
Flywheel 3 up vertically moves；Rotating nuts 94 counterclockwise, then third flywheel 3 vertically moves down with suspension hook 92.Suspension hook 92
On spin-ended piece 921 cooperate with the guide hole 931 of vehicle frame plate 93, limit the rotation of suspension hook 92；Limit plate 95 passes through two bolts 96
It is mounted on vehicle frame plate 93, limitation nut 94 moves up and down；Suspension hook 92 is threadedly coupled with nut 94；Therefore, rotating nuts
94 can only be such that suspension hook 92 moves up and down.Rotating nuts 94 make third flywheel 3 be in proper height and position, make crane 9
Third flywheel 3 is played on crane bracket 8 slowly to move toward the direction close to the second flywheel 2, and makes 3 inner end of third flywheel
The boss in face is matched with the pit of 2 corresponding end surface of the second flywheel, then passes through notch cuttype through hole 2 31 and spiral shell with screw 2 52
Pit 21 connects firmly third flywheel 3 and the second flywheel 2 together.
When the first flywheel 1 connected firmly with the second flywheel 2 needs to be moved on one on flywheel storing seat not with the second flywheel 2 one
When playing rotation, under loacting test rack stationary state, it is connected through a screw thread hanging ring 91 and the lifting eye 12 of the first flywheel 1, is hung
Ring and the cooperation of suspension hook 92 on ring 91 sling the first flywheel 1, unload all 4 screws 1 later, then make on crane bracket 8
Crane 9 plays the first flywheel 1 and slowly moves toward the direction far from the second flywheel 2, and the first flywheel 1 is made to be in flywheel storing
The surface of seat 1, last rotating nuts 94 fall in the first flywheel 1 slowly on flywheel storing seat 1.Third flywheel 3
It is moved on flywheel storing seat 2 62 that be moved to the operating method of flywheel storing seat 1 with the first flywheel 1 identical.
