Described intermediate comprises a hard intermediate and two flexible intermediate body, and described flexible intermediate body is arranged on respectively hard intermediate both sides, and described flexible intermediate body is provided with the through hole identical with gripping sleeve metal claw shape; Described hard intermediate is evenly divided into the left and right two-part that are connected as a single entity diametrically, and both sides are equipped with the cell body identical with metal claw shape, and the right side on the axial direction between adjacent two cell bodies in described left side is provided with cell body.
Further, described metal claw and circular body are structure as a whole.
Further metal claw is three.
Further, the circular body of described gripping sleeve is radially provided with the clearance groove from left side to right side through its central position, and described gap is higher than circular body radius, and wide is 1-3mm.
Further, described grooving is higher than circular body radius, and wide is 1-3mm.
Further, described flexible intermediate body is nitrile rubber.
Further, the Thickness Ratio of described two flexible intermediate body and hard intermediate is 1:1:4.
Further, in described circular body side surface direction perpendicular to axial direction, have counterbore, in described counterbore, be provided with screw thread, described counterbore is located at respectively two-part of the circular body being separated by clearance groove.
Advantage and the good effect that the utlity model has are: effectively overcome the shortcoming of prior art, have high pass moment of torsion, without back clearance, can effectively absorb the features such as vibration, eccentric drift angle.The Placement of flexible intermediate body and hard intermediate, make coupling damping effect remarkable, can effectively suppress resonance, gripping sleeve is added and fastens axle by clamp stud simultaneously, by metal claw, realize the link on axial direction, installing/dismounting is convenient, and grooving and clearance groove be arranged to step up better effects if.

Embodiment
As Figure 1-3, the technical solution of the utility model is: a kind of damping spring coupling, comprise two gripping sleeves 1 and an intermediate, and described two gripping sleeves are arranged on respectively intermediate both sides,
Described gripping sleeve comprises circular body 1 and along circular body 1 end face to axial direction, stretches out several along the metal claw 2 of this end face circumferential position array distribution, between adjacent two metal claws 2, form axial clearance, described circular body 1 through its central position be radially provided with from left side to right side, wide be the clearance groove 3 of 2mm higher than circular body 1 radius, described circular body 1 side surface is provided with the clamp stud through described clearance groove 3, is provided with a wide 2mm of being radially higher than the grooving 4 of circular body 1 radius on the right side of circular body side surface and clamp stud;
Described intermediate comprises a hard intermediate 5 and two flexible intermediate body 6 that material is nitrile butadiene rubber, described flexible intermediate body 6 is arranged on respectively hard intermediate 5 both sides, the Thickness Ratio of described two flexible intermediate body 6 and hard intermediate 5 is 1:1:4 simultaneously, and described flexible intermediate body 6 is provided with the through hole 7 identical with gripping sleeve metal claw 2 shapes; Described hard intermediate 5 is evenly divided into the left and right two-part that are connected as a single entity diametrically, and both sides are equipped with the cell body 8 identical with metal claw 2 shapes, and the right side on the axial direction between adjacent two cell bodies in left side is provided with cell body 8.
