The vibration isolating and reducing effects are excellent, and the vibration isolating and reducing functions are even and reliable.
Description
Technical field
The present invention relates to vibration damping, the vibration isolation technique field of transmission system, relate in particular to vibration damping, insulator in the transmission shaft system.。
Background technique
The axle system forms that adopt the segmentation axle of large-scale transmission shaft system adopt coupling to connect usually between driving shaft and the driven shaft.But in some engineering field,, connect through spline between driving shaft and the driven shaft, utilize a pair of spline pair that the moment of torsion of driving shaft is delivered to driven shaft for axle is easy for installation.Since the engagement between the spline pair, the vibration that is prone to produce axle system; Because spline pair plays a kind of effect of being rigidly connected, make the vibration of axle system be prone between the segmentation axle, transmit, there are not vibration damping, vibration isolating effect.
A kind of plantation rubber pin elastic coupling flexible coupling is disclosed among the utility application specification CN91226928.6 of China.This coupling is made up of inner ring, outer ring and a plurality of their middle plantation rubber pins that is installed in.This straight pin can transmitting torque, and the effect of playing certain buffering.But the plantation rubber pin since can not be evenly the whole space between filling inner ring, the outer ring continuously, vibration damping, vibration isolation action effect are relatively poor; In addition, discontinuous straight pin maybe be owing to existing shearing force to cut off the plantation rubber pin when transmitting moment of torsion bigger between inner ring, the outer ring, and it is unreliable to use.。
Summary of the invention
The applicant provides a kind of elasticity spline vibration isolator of drive line to above-mentioned existing technology vibration damping, the relatively poor problem of vibration isolation action effect, and its vibration isolation and damping is respond well, and vibration isolation and damping is all claimed reliably.
Technological scheme of the present invention is following:
A kind of elasticity spline vibration isolator; Comprise between annular inner ring, annular inner ring and the annular outer ring and have vibration isolation rubber; The inner ring surface of annular inner ring has spline, and the outer ring surface of annular inner ring and the inner ring surface of annular outer ring have outer double wedge and interior double wedge respectively, outer double wedge and interior double wedge cross arrangement; Keep spacing between the outer surface of said annular inner ring and the internal surface of annular outer ring, fill continuous vibration isolation rubber layer in the said spacing.
It is further characterized in that:
Said outer double wedge and interior double wedge have the circular arc top respectively, and two waists of outer double wedge and interior double wedge have tapering respectively; Said outer double wedge and interior double wedge are equidistantly arranged respectively; Keep proportional spacing between the outer surface of said annular inner ring and the internal surface of annular outer ring, fill the vibration isolation rubber layer in the said spacing.
The spline that it is symmetry that the inner ring surface of annular inner ring has with annular inner ring central shaft.
It is three pairs of splines of symmetry that the inner ring surface of annular inner ring has with annular inner ring center.
Beneficial effect of the present invention is following:
1, driving shaft connects annular inner ring, and the torque of driving shaft passes to rubber layer through the outer double wedge on the outer ring surface of annular inner ring, and rubber layer is given annular outer ring through the interior double wedge that connects on the inner ring surface of outer ring with transmission of torque again, and annular outer ring connects driven shaft.In the transmittance process of moment, owing to be filled with continuous vibration isolation rubber layer in the whole spacing between the internal surface of the outer surface of annular inner ring and annular outer ring, bigger area of contact is arranged so, vibration isolation and damping is respond well, and the effect that reduces transfer of vibration is remarkable.
2, the inner ring surface of the outer ring surface of annular inner ring and annular outer ring has outer double wedge and interior double wedge respectively; Outer double wedge and interior double wedge cross arrangement; Be filled with continuous vibration isolation rubber layer in the whole spacing between the outer surface of annular inner ring and the double wedge of annular outer ring internal surface; Outer double wedge and interior double wedge have the circular arc top respectively; Outer double wedge and in two waists of double wedge have tapering respectively, so structure guarantee vibration isolation rubber layer and annular inner ring and annular outer ring combine closely knit firmly, the reliability of assurance vibration isolation and damping.
3, outer double wedge and interior double wedge are equidistantly arranged respectively; Keep proportional spacing between the outer surface of said annular inner ring and the internal surface of annular outer ring; Fill continuous vibration isolation rubber layer in the said spacing, so structure assurance vibration isolation rubber layer is all claimed equal thickness, and assurance vibration isolation and damping effect is all claimed reliably.
4, the inner ring surface of the annular inner ring spline that to have with annular inner ring central shaft be symmetry prevents that the present invention from producing eccentric vibration when transmission, further improve all titles reliability of vibration isolation and damping effect.

Embodiment
Below in conjunction with accompanying drawing, embodiment of the present invention is described.
As depicted in figs. 1 and 2; The present invention includes annular inner ring 1, annular outer ring 3; Have vibration isolation rubber between annular inner ring 1 and the annular outer ring 3; The inner ring surface of annular inner ring 1 has spline, and the inner ring surface of the outer ring surface of annular inner ring 1 and annular outer ring 3 has 12 outer double wedges 4 and 12 interior double wedges 5 respectively, outer double wedge 4 and interior double wedge 5 cross arrangement; Keep spacing between the internal surface of the outer surface of said annular inner ring 1 and annular outer ring 3, fill the vulcanized rubber layer of vibration isolation in the said spacing.
Outer double wedge 4 and interior double wedge 5 have the circular arc top respectively, and two waists of outer double wedge 4 and interior double wedge 5 have tapering respectively.
Outer double wedge 4 and interior double wedge 5 are equidistantly arranged respectively., the outer double wedge 4 of design during double wedge 5, can calculate elasticity spline vibration isolator in the stress phase that receives under the torsional interaction in reaching according to the size of transmitting torque, and then according to the number and the shape of the performance design double wedge of rubber material.
Keep proportional spacing between the internal surface of the outer surface of said annular inner ring 1 and annular outer ring 3, fill the vibration isolation rubber layer in the said spacing.
It is the spline of symmetry that the inner ring surface of annular inner ring 1 has with annular inner ring 1 central shaft.
It is three pairs of splines of symmetry that the inner ring surface of annular inner ring 1 has with annular inner ring 1 center.
See Fig. 1, described connection outer ring 3 has one section attachment portion 6 vertically, and the surface Machining of said attachment portion 6 has internal thread, is used for connecting driven shaft.Said screw thread can also can be processed at its outer surface in the internal surface processing of attachment portion.
When driving shaft or driven shaft produce vibration, because rubber material has the function of energy dissipation in the elasticity spline vibration isolator, reduced the coupling stiffness of driving shaft and driven shaft, thereby reduced the transfer of vibration between axle is.
