Embodiment
As Figure 1-3, technological scheme of the present invention 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.
In the present embodiment, described 3 metal claws 2 are structure as a whole with circular body 1, and the shape of described metal claw 2 is any, and its cross section can be fan-shaped, can be triangle, can be also crescent shape.In the present embodiment, its cross section is fan-shaped, and area of contact is larger, and when circular body is subject to the extruding of positive pressure, frictional force is larger, and locking effect is better, is especially applicable to motor frequently during clockwise and anticlockwise.
Working principle of the present invention and beneficial effect:
A when hard intermediate 5 of damping spring coupling is connected with axle with two flexible intermediate body 6, by clamp stud, make gripping sleeve produce flow of metal, directly contact with axle, so just can hold driving shaft and driven shaft tightly.When closed coupling is installed, circular body both ends of the surface can be subject to the effect of positive pressure, make grooving produce the flow of metal of 1-3mm, thereby realize axial grip, fix.
As shown in Figure 1, a kind of damping spring coupling comprises two gripping sleeves, a hard intermediate 5 and two flexible intermediate body 6, first a flexible intermediate body 6 and hard intermediate 5 are packed into the gripping sleeve in left side, metal claw 2 on gripping sleeve is also fitted with it through the through hole 7 on flexible intermediate body 6 and hard intermediate 5, again the gripping sleeve on right side is packed into a flexible intermediate body 6 and hard intermediate 5, make equally the metal claw 2 on gripping sleeve also fit with it through the through hole 7 on flexible intermediate body 6 and hard intermediate 5, in described circular body 1 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 1 being separated by clearance groove 3, bolt is placed in counterbore, by screw thread, two-part of the gripping sleeve by separated are fixed.
Fig. 2 is the end view drawing of gripping sleeve of the present invention, in the side surface of circular body direction perpendicular to axial direction, have counterbore and tapped hole, by clamping bolt, make the gripping sleeve of coupling produce flow of metal, damping spring coupling endoporus and axle close contact, produce frictional force, rotaryly can not skid, play the effect of carry-over moment.
