Detailed Description
Referring to fig. 1-2, the present invention provides an improved structure of a flexible coupling, including: rubber body 1, rubber body 1 have the centre bore 2 and the circumference equipartition that link up its central point position at a plurality of mounting holes of 2 peripheries of centre bore, all are equipped with rather than fixed assembly's tubular metal resonator 3 in every mounting hole, wherein:
the inside of mounting hole just is located and is equipped with the circumference slot 4 that extends along its inner wall circumference between its both ends, and the inside of mounting hole is equipped with along its inner wall axial extension's axial slot 5, forms buffer space between circumference slot 4 and axial slot 5 and the tubular metal resonator 3 outer wall. Due to the design of the structure, when the flexible coupling is subjected to torsional vibration and impact load, the circumferential groove 4 can provide a buffer space for the deformation of rubber when the rubber body 1 is axially compressed, so that the radial expansion of the rubber caused by axial compression is prevented, and the metal pipe 3 is further extruded to cause the deformation of the metal pipe 3; the axial grooves 5 can provide a buffer space for the deformation of the rubber when the rubber body 1 is subjected to a torsion force, so as to prevent the rubber from causing tearing lines due to excessive torsion force.
From the above, the utility model discloses have longer life, and be difficult for appearing dismantling the problem of difficulty because of tubular metal resonator 3 warp and cause the later stage.
Specifically, the method comprises the following steps: an included angle is formed between the surface of the circumferential groove 4 and the axial lead of the mounting hole, so that the surface of the circumferential groove 4 is of an inclined surface structure, the structural design weakens the influence of the axial groove 4 on the strength of the rubber body 1, and the damping effect of torsional vibration and impact load can be simultaneously achieved.
In addition, in this embodiment, the portion of the rubber body 1 located between any two adjacent mounting holes has a notch 6 recessed from the outer wall thereof to the central portion thereof, specifically: the gap 6 is of an arc structure. The design of the gap 6 can form a torsion buffer space between two adjacent metal pipes 3, and then the service life of the flexible coupling is further prolonged.
The above, only be the embodiment of the preferred of the present invention, but the protection scope of the present invention is not limited thereto, and any person skilled in the art is in the technical scope of the present invention, according to the technical solution of the present invention and the utility model, which are designed to be replaced or changed equally, all should be covered within the protection scope of the present invention.
