Degree of taking over cooperation, bolt need firmly to tap during installation and removal, and especially in device context, installation space is small, inconvenience behaviour
Make, equipment component is even more to forbid tapping, and causes bolt installation and removal difficult.When equipment run a period of time after, need to change or
It overhauls diaphragm group (vulnerable part), due to the influence of environment, part bolt has slight deformation or corrosion, and disassembly at this time is rare bigger,
Not only large labor intensity also substantially prolongs the repair time；Even cause shaft coupling ontology on service life well below pre-
If value；Because the crucial torque of shaft coupling ontology transmits articulation bolt hole location advanced wear, especially diaphragm group (vulnerable part) stress
Serious unevenness premature deterioration, unit vibration are serious, lose the greatest flexibility vibration-damping function of diaphragm coupling, or even cause unit
Damage, brings great loss to production.
Summary of the invention
The purpose of this utility model is to provide a kind of double tapered expansion sleeve type films convenient for disassembly and assembly and that service life can be improved
Piece shaft coupling.
The purpose of this utility model is achieved through the following technical solutions:
A kind of double tapered expansion sleeve type diaphragm coupling, including two flanges, the diaphragm group being arranged between two flanges, with
And the double tapered expansion set component of two flanges and diaphragm group is fixed, the double tapered expansion set component includes inner expension cap, swollen outside first
Set, the second outer expansion set, screw and nut, inner expension cap are provided with through-hole along axial direction, and the inner wall at through-hole both ends, which slopes inwardly, forms cone
Degree, the first outer expansion set and the second outer expansion set is separately mounted to the both ends of through-hole and its outer wall is matched with through-hole wall, outside first
Expansion set and the second outer expansion set are axially provided with screw hole along it, and screw passes through the screw hole of the first outer expansion set and the screw hole of the second outer expansion set
And the rear thread that extends outwardly is matched with nut, and the screw hole bottom outlet of the first outer expansion set is bigger than screw thread outer diameter, and described second
The screw hole of outer expansion set is matched with screw thread.
Further, the inner expension cap positioned at second outer expansion set one end is provided with bushing.
Further, diaphragm group two sides are equipped with rivet.
The utility model has the following beneficial effects:
(1) flange is connected by double tapered expansion set component with diaphragm group, can not only realizes connection and intermal force, may be used also
It improves the efficiency of installation or removal and reduces working strength；
(2) by being arranged between the first outer expansion set and screw there are gap, to be screw thread between the second inner expension cap and screw
Cooperation, it is not affected by environment convenient for the disassembly and installation of screw.
Detailed description of the invention

Specific embodiment
As shown in Figure 1, double tapered expansion sleeve type diaphragm coupling provided in this embodiment includes active flange 1, driven flange
2, diaphragm group 3, double tapered expansion set component 4 and rivet 5, the edge of the active flange 1, driven flange 2 and diaphragm group 3 are opened
There is corresponding mounting hole, double tapered expansion set component 4 is mounted on mounting hole and realizes active flange 1, driven flange 2 and diaphragm group 3
It links together, the two sides of the 5 diaphragm group 3 of rivet can be same as compressing diaphragm group 3.
As shown in Fig. 2, the double tapered expansion set component 4 include inner expension cap 41, the first outer expansion set 42, the second outer expansion set 43,
Bushing 44, screw 45 and nut 46, inner expension cap 41 are provided with through-hole along axial direction, and the inner wall at through-hole both ends, which slopes inwardly, forms cone
Degree, the i.e. diameter at through-hole both ends are greater than the diameter in the middle part of through-hole, and the first outer expansion set 42 and the second outer expansion set 43 are separately mounted to lead to
The both ends in hole and its outer wall is matched with through-hole wall, i.e., the first outer expansion set 42 and the second outer 43 shape of expansion set are similar with boss,
First outer expansion set 42 and the second outer expansion set 43 are axially provided with screw hole along it, and screw 45 passes through the screw hole and the of the first outer expansion set 42
The screw hole of two outer expansion sets 43 and successively screw thread is matched with bushing 44 and nut 46, the end of bushing 44 and inner expension cap 41 after extending outwardly
