Fig. 2 is another embodiment of the present utility model.
Description of reference numerals: cylinder body 1, flexible hinge portion 2, threaded joints 3, bolt head 4, elastomeric pad 5, elasticity
Set 6, reinforcing sleeve 7.
Detailed description of the invention
Below in conjunction with accompanying drawing, the technical solution of the utility model is described further.
As it is shown in figure 1, the flexible fastener bolt of elastic coupling of the present utility model, including cylinder body 1, flexible hinge
Portion 2, threaded joints 3, bolt head 4, elastomeric pad 5, resilient sleeve 6, wherein flexible hinge portion 2 is arranged on cylinder body 1 and spiral shell
Between stricture of vagina connecting portion 3, the diameter of cylinder body 1 is identical with the diameter of threaded joints 3 and more than the diameter in flexible hinge portion 2,
I.e. the diameter of cylinder body 1 is more than the diameter in flexible hinge portion 2, and cylinder body 1, flexible hinge portion 2 are all polished rod cylinder.
Cylinder body 1 of the present utility model, flexible hinge portion 2, threaded joints 3, bolt head 4 need flexible preferably material
Matter, preferably 18Cr2Ni4WA material, this material belongs to alloy carburizing steel in high intensity, so can improve this utility model soft
Property the intensity of fastening bolt and amount of deflection, its strength grade improves to 8.8 grades, improves amount of deflection simultaneously.
As it is shown in figure 1, cylinder body 1 rear end of the present utility model arranges bolt head 4, set up elasticity in bolt head 4 front portion
Pad 5, sets up resilient sleeve 6 outside cylinder body 1, and elastomeric pad 5 of the present utility model, resilient sleeve 6 can use vulcanie
Manufacture.During use, overlap top nut at threaded joints 3, by the pressure between twisting nut regulation bolt head 4 and elastomeric pad 5
Power, and under the common effect of resilient sleeve 6, thus it is possible to vary bolt head 4 and being rigidly connected that elastic coupling clutch plate is connected, make
There is not covibration in flexible fastener bolt and elastic coupling clutch plate.
Flexible hinge portion 2 of the present utility model area can not the most greatly can not be the least, its reason is if flexible hinge
Portion 2 area is the least, then, in transmission process, be easily broken off during the torsion that its parts are subject to, but can not be too big, if flexible hinge
Chain portion 2 area is too big, then the flexibility between cylinder body 1 and threaded joints 3 dies down, and also holds when the torsion that these parts are subject to
Easy fracture.Through test of many times, when cylinder body 1, flexible hinge portion 2, threaded joints 3, bolt head 4 all use chromium nickel to close
When gold copper-base alloy manufactures, flexible hinge portion 2 of the present utility model cylinder diameter is between 10mm to 14mm, and it is flexible preferably,
Not easy fracture, preferably 12mm during use.
In order to improve flexibility of the present utility model further, this utility model can suitably increase flexible hinge portion 2, flexible
Hinge 2 length range its flexibility within 30mm to 40mm is preferable, and flexible fastener bolt body also will not be oversize, meets many
Practicality in the case of number.As flexible hinge portion 2 being set to 35mm, cylinder body 1, threaded joints 3 be respectively set to 20～
30mm。
Owing to the flexible hinge portion 2 of this utility model depression is longer, in order to be suitable for the installation requirements of different mounting location, this
Flexible hinge portion 2 outer layer of utility model sets up reinforcing sleeve 7, and this reinforcing sleeve 7 can fill up the place of flexible hinge portion 2 depression,
As in figure 2 it is shown, this reinforcing sleeve 7 can make flexible fastener bolt adapt to the installation requirements propping up bracer of different-diameter.This reality
Elastomeric material can be used to support with novel reinforcing sleeve 7, it is also possible to using two pieces of semi-circular cylindrical to be spliced, as strengthened
Set 7 is rigid member, then splicing can only be used to manufacture.
Using method of the present utility model is: flexible fastener bolt, through the hole of elastic coupling clutch plate, makes cylinder
Portion 1 contacts with elastic coupling clutch plate, and threaded joints 3 contacts with a bracer, overlaps top nut at threaded joints 3, then
Tightening nut.By the fixing connection of multiple flexible fastener bolts, elastic coupling clutch plate is linked together with a bracer.
During work, a bracer drives elastic coupling clutch plate to rotate together.In diesel engine elastomeric coupling works, pass through flexible hinge
Under chain portion 2, elastomeric pad 5, resilient sleeve 6 act on jointly, excessive load percussion can be absorbed, make of the present utility model soft
Property fastening bolt be not easy fracture.
