Four ratchets 32 rotation, so that the resistance very little for needing to overcome is opposite convenient for fixed frame 1 when the mobile reset of fixed frame 1 to the left
It is resetted in support base 2.
The driving gear 9 is half gear, fixed frame 1 relative to support base 2 side is deflected over initial position backward when, it is main
Moving gear 9 and driven gear 10 are disengaged from.Fixed frame 1 relative to support base 2 forward lateral deviation turn only be more than initial position after,
It could make the first frictional disk 16 and the second frictional disk 17 that opposite rotation occur, lateral deviation turns over initially such fixed frame 1 backward
Behind position, be then reset to initial position this during, driving gear 9 and driven gear 10 are in not meshing state, no
It can make the first frictional disk 16 and the second frictional disk 17 that opposite rotation occur, the energy of such second pressure spring, 8 deformation savings can
Fixed frame 1 is reset to initial position, do not will cause because the effect of the first frictional disk 16 and the second frictional disk 17 cannot make admittedly
Determine the case where frame 1 resets very well.
When movement occurs to the left for the rotor 4 more than initial position relative to support base 2, the first rack gear 19 and first
Gear 20 is disengaged from.Fixed frame 1 is mobile only more than after initial position to the right relative to support base 2, can just make first to rub
It wipes disk 16 and the second frictional disk 17 and occurs opposite rotation, such fixed frame 1 is moved to the left beyond after initial position, then is reset to
During this of initial position, because the first rack gear 19 and the second rack gear are not on meshing state, it would not also make first
Opposite rotation occurs for frictional disk 16 and the second frictional disk 17, and the energy of 7 deformation of the first pressure spring savings can reset fixed frame 1
To initial position, not will cause because the effect of the first frictional disk 16 and the second frictional disk 17 cannot be such that fixed frame 1 resets very well
The case where.
The first friction dish axle 13 drives the rotation of the first frictional disk 16, and the first frictional disk 16 can be along the first friction dish axle
13 axial movements have the first friction pressure spring covered in the first friction dish axle 13 between the first frictional disk 16 and first bearing seat 12
40, the second friction dish axle 15 drives the rotation of the second frictional disk 17, and the second frictional disk 17 can axially be moved along the second friction dish axle 15
It is dynamic, there is the second friction pressure spring 41 covered in the second friction dish axle 15 between the second frictional disk 17 and second bearing seat 14, the
Under the action of one friction pressure spring 40 and the second friction pressure spring 41, the first frictional disk 16 is fitted closely with the second frictional disk 17.

3901, interconnecting piece 501, which is inserted into connecting hole 3901, to be driven the rotation of drive sleeve 39 and can slide in drive sleeve 39, driving gear 9
Be fixedly and coaxially connected with drive sleeve 39, interconnecting piece 501, drive sleeve 39 constitute left guide rod 5 can drive driving gear 9 rotate but also
The structure relatively moved with driving gear 9.Interconnecting piece 501 is realized with drive sleeve cooperation, can transmit the rotation of rotor 4
To driving gear 9, and driving tooth can be made by the relative movement of left guide rod 5 and driving gear 9 when rotor 4 is mobile
9 positions are taken turns to remain stationary.
When specifically used, motor 42 is mounted on fixed frame 1 present invention, and pedestal 3 is installed in rack.Motor 42 occurs
When vibration, fixed frame 1 beyond initial position and when continuing deflection, will drive the rotation of driving shaft 11 to front side relative to support base 2,
Driving shaft 11 drives the first friction dish axle 13 to rotate by the first ratchet 24, second ratchet 25 etc., and then 16 turns of the first frictional disk
Dynamic, because the effect of the 4th ratchet 32 and the 4th pawl 36 will not be driven by the first frictional disk 16, first rubs the second frictional disk 17
It wipes disk 16 to relatively rotate with the second frictional disk 17, friction consumption energy plays damping effect.
When fixed frame 1 moves right beyond initial position and continues to move to relative to support base 2, bevel gear shaft 23 will drive
Rotation, bevel gear shaft 23 drives the second friction dish axle 15 to rotate by third ratchet 31, the 4th ratchet 32 etc., and then the second friction
Disk 17 rotates, and the first frictional disk 16 will not be driven because of the effect of the second ratchet 25 and the second pawl 29 by the second frictional disk 17,
First frictional disk 16 relatively rotates with the second frictional disk 17, and friction consumption energy plays damping effect.
The present invention converts frictional heat for vibration by the relative rotation of two frictional disks and consumes, and reduces vibration width
Degree so damping effect is obvious, guarantees the normal work of motor, reduces to the other components of machine since vibration frequency is very high
Vibration, avoid while also can increase the service life of components because the disengaging of certain components causes irremediable consequence.Significantly
Noise is reduced, the working environment of factory is improved.
Embodiment described above is not intended to limit the scope of the present invention, before not departing from design concept of the present invention
It puts, the various changes and improvements that those skilled in the art make technical solution of the present invention should all be included in the present invention
Claims determine protection scope in.
