Described compression spring set shakes for reducing the rotation produced because of relative motion between the first mass body 1 and the second mass body, and described compression spring set forms by being arranged in order under the most unconfined state of multiple compression springs.The flange I 21 stopping pin I and described driving dish 20 that the two ends of compression spring set described in one of which are provided with by described first mass body 1 respectively supports, and the flange II 22 stopping pin II and described driving dish 20 that another two ends organizing described compression spring set are provided with by described first mass body 1 respectively supports.Described compression spring includes big spring 40 and the little spring 50 being contained in big spring 40.
The first contact surface between two described spring end containing components in the middle of the flange I 21 and flange II 22 of described driving dish 20 all tilts to the flange I 21 of described driving dish 20 or flange II 22 with the contact surface of adjacent two the spring end containing components between the flange I 21 of described driving dish 20 or flange II 22.
nullIn an embodiment of the present utility model，Each described compression spring set is equipped with four compression springs，The spring end containing component being arranged at two compression spring two ends to the position (centre position between flange I 21 and flange II 22) being separated by 90 degree by the flange I 21 of described driving dish 20 is followed successively by: spring end containing component I 30-1、Spring end containing component II 30-2、Spring end containing component III 30-3 and spring end containing component IV 30-4，The flange I 21 towards described driving dish 20 that contacts of described spring end containing component II 30-2 and spring end containing component III 30-3 tilts，And this contact surface has the bias of angle a with the center of described driving dish 20 and the line AC at this contact surface center，I.e. the extended surface of this contact surface is without the center C of described driving dish 20，Eccentric direction should be towards the direction of described flange I 21.
The spring end containing component being arranged at two compression spring two ends to the position (centre position between flange I 21 and flange II 22) being separated by 90 degree by the flange II 22 of described driving dish 20 is followed successively by: spring end containing component V 32-1, spring end containing component VI 32-2, spring end containing component VII 32-3 and spring end containing component VIII 32-4, the center of the contact surface of described spring end containing component VI 32-2 and spring end containing component VII 32-3 and described driving dish 20 has the bias of angle a, i.e. the extended surface of this contact surface is without the center C of described driving dish 20.
The contact surface of described spring end containing component VIII 32-4 and spring end containing component IV 30-4 is the first contact surface, this first contact surface is positioned at flange I 21 and the centre position of flange II 22, and elongated surfaces BC of this first contact surface is through the center C of described driving dish 20.
In like manner, another group compression spring set that the flange II 22 stopping pin II and described driving dish 20 that two ends are provided with by described first mass body 1 supports, the compression spring set structure of flange I 21 support with the stopping pin I being provided with by described first mass body 1 and described driving dish 20 is identical and is arranged symmetrically with.
Each described spring end containing component is provided with and puts order groove 5 as put sequence notation, and the order groove 5 of putting on adjacent two described spring end containing components is connected.
In an embodiment of the present utility model, from the beginning of the flange I 21 of described driving dish 20, on spring end containing component to the centre of flange I 21 and flange II 22, spring end containing component I 30-1 is provided with one and puts order groove 5, being provided with two in the side of spring end containing component II 30-2 and put order groove 5, opposite side is provided with one and puts order groove 5.Spring end containing component III 30-3 adjacent with spring end containing component II 30-2 is provided with and puts order corresponding two of groove 5 with two that the side of described spring end containing component II 30-2 is provided with and put order groove 5, opposite side is provided with described spring end containing component II 30-2 opposite side and puts order be connected one of groove 5 and put sequentially groove 5, makes assembler easily identify spring end containing component II 30-2 that should assemble.Spring end containing component IV 30-4 side is provided with three and puts order groove 5, and opposite side is provided with one and puts order groove 5, represents and starts the 4th the spring end assembling parts placed from flange I 21.This placement order groove is equally applicable on the spring end containing component that opposite side is placed, and does not carry out other explanation.
Operation principle of the present utility model is:
When producing rotation between the first mass body 1 and driving dish 20, spring end containing component I 30-1 and spring end containing component V 32-1 at compression spring set two ends and produce between joint spring end containing component II 30-2 and spring end containing component II 30-2 slide respectively.Now, spring end containing component I 30-1 and spring end containing component V 32-1 extrudes to driving dish 20 side, therefore by deformation torsion inside flange I 21.Now, compression spring set produces frictional force with inner friction surface 200, and this class formation applies deformation torsion relatively in the outside of flange I 21, and the probability of flange I 21 breakage can significantly decrease.When electromotor height rotating speed rotates, compression spring set produces frictional force in outer friction surface 100, and spring end containing component I 30-1 and the spring end containing component V 32-1 outer surface of flange I 21 can produce abrasion.Therefore, in spring end containing component I 30-1 and spring end containing component V 32-1 at compression spring set two ends, can wear and tear uniformly in outside.
The operation principle of symmetrically arranged two groups of compression spring set is identical.
The first contact surface that spring end containing component IV 30-4 that this utility model center between flange I 21 and flange II 22 is placed contacts with spring end containing component VIII 32-4, another group spring end containing component IV 31-4 with another organize spring end containing component VIII 33-4 contact another organize the first contact surface, towards the center C of driving dish 20, non-angular is eccentric.Therefore, relatively the most adjacent with flange I 21 and flange II 22 spring end containing component (spring end containing component I 30-1, another group spring end containing component I 31-1, spring end containing component V 32-1, another organize spring end containing component V 33-1) stroke is short, in the slow-speed of revolution and the high-revolving interval advantage all with uniform wear of overall use.
Double mass flywheel in this utility model, i.e. prevents driving dish flange damaged, moreover it is possible to prevention compression spring set causes the partial wear of a part when by using and abrasion occurring.Putting order groove also by being formed at spring end containing component, when preventing assembling double mass flywheel, spring end containing component puts sequence error.
The foregoing is only embodiments of the present invention, be not intended to limit protection scope of the present invention.All made within the spirit and principles in the present invention any modification, equivalent substitution and improvement, extension etc., be all contained in protection scope of the present invention.
