It is dynamic, so that speed adjusting gear 5 is generated the axial force for deviating from first axle 1, then drives the 4th disk 42 close to the second disk 32, at this time the 4th disk
42 and the second air gap between disk 32 reduce.Meanwhile the 4th disk 42 pull the second connecting rod 64 to away from first support bar 61
Direction is mobile, i.e., the second connecting rod 64 moves to right.Second pin shaft 66 is in the second slot 622 to the direction for deviating from first support bar 61
Sliding, i.e., the second pin shaft 66 moves up.And then the first bull stick 62 is pulled to rotate clockwise around first support bar 61.Due to first turn
Bar 62 rotates clockwise, and the first pin shaft 65 is driven also to slide to the direction away from first support bar 61 in the first slot 621,
I.e. the first pin shaft 65 moves down.And then push first connecting rod 63 to, i.e., first connection mobile away from the direction of first support bar 61
Bar 63 moves to left.Drive third disk 41 close to the first disk 31 again, the air gap between third disk 41 and the first disk 31 also subtracts therewith at this time
