Abstract
The utility model discloses an SMA damping connector, comprising a screw sleeve, a first gasket, a second gasket, a rubber ring, a clamp ring and a shell; the screw sleeve and the shell are connected by the clamp ring; the screw sleeve and the shell are respectively tightly matched with the first gasket and the second gasket; the rubber ring is positioned between the first gasket and the second gasket. Surfaces of the two gaskets are adopted to extrude the rubber ring, and the influence to on the axial size caused by the connection of the clamp ring is avoided.
Description
Technical field
The utility model relates to a kind of connector, particularly relates to a kind of SMA damping connection.
Background technique
Existing SMA damping connection is that the frictional force by directly producing between shell, swivel nut both ends of the surface and seal ring forms damping.There is following problem in existing SMA damping connection: one, and damping strength is unstable.Two, because adopting snap ring, shell and swivel nut be connected, for guaranteeing to rotate, between part, must there is appropriate gap, the length dimension control difficulty of the extruding rubber ring making, is not easy to processing.
Model utility content
Technical problem to be solved in the utility model is to provide a kind of SMA damping connection, and it has adopted the contact of two washer face extruding rubber rings, has avoided adopting snap ring to connect the impact of the axial dimension causing.
The utility model solves above-mentioned technical problem by following technical proposals: a kind of SMA damping connection, it is characterized in that, it comprises swivel nut, the first packing ring, the second packing ring, rubber ring, snap ring, shell, between swivel nut and shell, by snap ring, be connected, swivel nut and shell respectively with the first packing ring, the second packing ring close-fitting, rubber ring is between the first packing ring and the second packing ring.
Preferably, the material of the material of described the first packing ring and the second packing ring is all teflon.
Positive progressive effect of the present utility model is: the utility model has adopted the contact of two washer face extruding rubber rings, has avoided adopting snap ring to connect the impact of the axial dimension causing.Two packing rings adopt teflon processing, have increased ductility, have guaranteed the stability of damping.The utility model has increased damping stability, has guaranteed the reliability of using.
Accompanying drawing explanation
Fig. 1 is the structural representation of the utility model SMA damping connection.
Embodiment
Below in conjunction with accompanying drawing, provide the utility model preferred embodiment, to describe the technical solution of the utility model in detail.
As shown in Figure 1, the utility model SMA damping connection comprises swivel nut 1, the first packing ring 21, the second packing ring 22, rubber ring 3, snap ring 4, shell 5, between swivel nut 1 and shell 5, by snap ring 4, be connected, swivel nut 1 and shell 5 respectively with the first packing ring 21, the second packing ring 22 close-fittings, rubber ring 3 is between the first packing ring 21 and the second packing ring 22.
SMA damping connection mainly produces damping by shell and swivel nut, guarantee usage requirement, process is as follows: between swivel nut and shell, by snap ring, be connected, and guaranteed to connect reliable and freely rotated, swivel nut and shell respectively with two packing ring close-fittings (material of two packing rings is teflon), by washer face, push rubber ring and produce and stablize damping.Between swivel nut and shell, by card, 4 be connected, like this can shell and swivel nut can freely rotate.Swivel nut and shell respectively with the first packing ring, the second packing ring close-fitting, avoided like this swivel nut, shell directly to contact with rubber ring.Rubber ring is between the first packing ring and the second packing ring, and rubber ring, by two packing ring extrusion-deformations, produces resistance.
The utility model has adopted the contact of two washer face extruding rubber rings, has avoided adopting snap ring to connect the impact of the axial dimension causing.Two packing rings adopt teflon processing, have increased ductility, have guaranteed the stability of damping.The utility model has increased damping stability, has guaranteed the reliability of using.
Those skilled in the art can carry out various remodeling and change to the utility model.Therefore, the utility model has covered various remodeling and the change in the scope that falls into appending claims and equivalent thereof.
Claims (2)
1. a SMA damping connection, it is characterized in that, it comprises swivel nut, the first packing ring, the second packing ring, rubber ring, snap ring, shell, between swivel nut and shell, by snap ring, be connected, swivel nut and shell respectively with the first packing ring, the second packing ring close-fitting, rubber ring is between the first packing ring and the second packing ring.
2. SMA damping connection as claimed in claim 1, is characterized in that, the material of the material of described the first packing ring and the second packing ring is all teflon.
