When 9a, 9b are moved axially, it will pull short connecting rod 11a, 11b, while drive long connecting rod 12a, 12b and quality adjustment block 7a,
7b is moved.
The size of rotary inertia is relevant with the size of the quality of rotating part and the radius of gyration.The inertia regulation of the present invention
Function is realized with Flywheel disc 6 and bevel gear disk 3, is turned by changing mass 8 apart from the distance of the axis of flywheel shaft 2 to change
The size of dynamic inertia.Change quality adjustment block 7a, 7b the distance between to the central axis of flywheel shaft 2, and then change quality and adjust
Radius of gyration when locking nub 7a, 7b rotates with Flywheel disc 6, it is finally reached the purpose of the rotary inertia of fine setting Flywheel disc 6.
As shown in Figure 6 and Figure 7, for the present invention in initial rest state, bevel gear disk 3 is placed on bearing block 1 in the same direction
On boss, two masses 8 and two quality adjustment block 7a, 7b each in relative to the position substantially symmetrical about its central axis of Flywheel disc 6,
Now Flywheel disc 6 and equal with the identical in quality and radius of gyration for the symmetrical parts that Flywheel disc 6 is connected, whole device is in
Poised state and by flywheel shaft 2 intermediate 9 can be driven to rotate, then pass through short connecting rod 11a, 11b and long connecting rod 12a, 12b are formed
Two linkage flywheel driven disks 6 and its connector integral-rotation, carry out rotary inertia simulation.
When flywheel needs to change as requested the rotary inertia of device, need to be adjusted when device remains static, will
Original bevel gear disk 3 being placed on the boss of bearing block 1 moves to the direction of Flywheel disc 6, makes bevel gear and the leading screw of bevel gear disk 3
5 inner bevel pinions 14 engage.Now, bevel gear disk 3 is can be manually rotated, leading screw 5 is driven by bevel gear and bevel pinion 14
Rotate so that mass 8 is while leading screw 5 rotates, radially inside and outside movement, changes the radius of gyration of mass 8, realizes and turns
The step-less adjustment of dynamic inertia.
When the defects of flywheel generation non-uniform mass, the device can realize that rotation is used during flywheel turns
Measure the function of calibrating automatically.Shown in Figure 7, now the two side direction Mass Distributions up and down at flywheel center differ, and can cause
The centrifugal force that two side portions are subject to up and down during flywheel turns is different, it is assumed that defect is now produced on the upside of flywheel and causes quality to subtract
It is few, and then cause top rotary inertia to reduce, when flywheel turns, downward, the flywheel of making a concerted effort for the centrifugal force that above-below direction is subject to
Disk 6 can overcome axial downward movement of the power of helical spring 13 along positioning vertical column 9b, while the mass being connected with Flywheel disc 6
8th, quality adjustment block 7a, 7b, leading screw 5, two linkages, pressing plate 4 can all move downwardly together.Now, Flywheel disc free bearing 6a with
Flywheel integrally to move down, be further driven to short connecting rod 11a and rotate certain angle in the counterclockwise direction around Flywheel disc free bearing 6a
Degree, the included angle A between short connecting rod 11a and the card of Flywheel disc 6 can reduce；Long connecting rod 12a is under short connecting rod 11a pulling force effect
Certain angle, the included angle B meeting between long connecting rod 12a and the central shaft of Flywheel disc 6 are rotated in an anti-clockwise direction around intermediate free bearing 9c
Increase, the reduction of included angle A and the increase of included angle B cause quality adjustment block 7a to move up a segment distance relative to home position,
Increase with the distance of flywheel shaft 2, at the same time, the Flywheel disc free bearing 6b of bottom integrally moves down with flywheel, can further band
Dynamic short connecting rod 11b turns an angle in the counterclockwise direction around Flywheel disc free bearing 6b, shows as short connecting rod 11b and Flywheel disc 6
Card between angle C increases, long connecting rod 12b is under short connecting rod 11b pulling force effect around intermediate free bearing 9d along the inverse time
Pin direction turns an angle, and the angle D shown as between long connecting rod 12b and the central shaft of Flywheel disc 6 diminishes, quality adjustment block 7b
Moved up relative to home position, reduced with the distance of flywheel shaft 2, cause the rotary inertia of flywheel bottom to diminish.Due to flying
The centrifugal force that wheel top and the bottom quality inequality is brought makes flywheel main body move down always, and the displacement will make quality adjustment block
7b continues upward movement, so as to continuously cause the inertia on top to increase the reduction with the rotary inertia of bottom, until upper and lower two
When the rotary inertia divided is equal, the displacement of Flywheel disc 6 no longer changes, and now the rotary inertia of the top and the bottom of flywheel main body is put down
, flywheel inertia imbalance state eliminates, it is achieved thereby that the automatic calibration of rotary inertia.
