In addition, although flexible couplings made of nonmetallic materials are produced in the existing coupling products, the structural rigidity of the couplings is not reliably ensured, and when the couplings are subjected to torsion acting force, the deformation is too large or too small, so that the reliable guarantee of the materials of the couplings is difficult.

The specific meaning of the above terms in the creation of the present invention can be understood by those of ordinary skill in the art in a specific case.
The invention will be described in detail below with reference to the drawings in connection with embodiments.
A unitary coupling, as shown in fig. 1 to 3, comprises an inner base body 1 and a sheath 2 outside the base body 1; the base body 1 comprises a spiral elastomer 3 in the middle and fixing sleeves 4 arranged at two ends of the spiral elastomer, and a connecting section 5 is arranged on one side of the fixing sleeves 4 facing outwards; the spiral elastomer 3 and the fixed sleeves 4 at the two ends of the spiral elastomer are simultaneously wrapped by the protective layer 2; the thickness of the upper protective layer of the spiral elastomer 3 is larger than that of the upper protective layer of the fixed sleeve, and the inner diameter of the spiral elastomer part wrapped with the protective layer is larger than that of the fixed sleeve part; a plurality of connecting holes 6 are uniformly distributed on the connecting section 5 along the circumferential direction. It should be noted that the sheath 2 preferably adopts a reinforced and toughened nylon layer, which has strong impact resistance, high strength and certain elasticity. The outside sheath of base member once processing shaping, whole cladding is in the base member outside, and shaft coupling overall stability obtains reliable guarantee, and the equilibrium is better.
Typically, the inner diameter of the spiral elastomer portion 7, which is wrapped with the sheath, is 5-10mm larger than the inner diameter of the fixing sleeve portion 8. After the fixing sleeve is connected with the corresponding shaft body, the inner wall of the cavity 9 in the middle of the coupler cannot touch the shaft body, and in the running process of equipment, as the spiral elastomer part in the middle of the coupler has certain deformation, the inner diameter of the spiral elastomer part is 5-10mm larger than that of the fixing sleeve, and the part where the spiral elastomer is can be effectively ensured not to interfere with the connected shaft body.
The transition part of the protective layer on the spiral elastomer 3 and the fixed sleeve 4 is of a conical structure, the thickness of the protective layer is gradually reduced from the spiral elastomer to one side of the fixed sleeve, stress concentration at the transition position of the protective layer of the spiral elastomer and the fixed sleeve is avoided, and the stability of the whole structure is ensured.
The spiral elastic body 3 preferably adopts a spiral spring, has good tensile, compressive and torsion resistance, is matched with the sheath structure, greatly improves the tensile and torsion resistance of the coupler, and has longer service life even under complex and heavy working conditions. Of course, the spiral elastic body can be made of other materials, so long as the skeleton supporting function can be well achieved, the elastic body has higher elasticity, and the elastic body is good in that no permanent deformation exists after torsion and stretching.
When the coupler is subjected to torsion acting force, the spiral elastomer has certain rigidity and is used as a skeleton support of a torsion deformation part in the middle of the coupler, and the spiral elastomer can generate certain deformation and simultaneously effectively inhibit excessive deformation, so that the whole coupler is stable and reliable and is not easy to damage.
The fixing sleeve 4 is an aluminum alloy fixing sleeve, and is light in weight, high in strength and reliable in connection with the shaft body.
A plurality of slots 10 are arranged on the protective layer on the outer side of the spiral elastic body 3 at intervals, and the slots 10 are arranged along the outer circumferential direction of the protective layer. Specifically, the depth of the slot is 1/3-1/2 of the thickness of the protective layer, and the width is 0.5-1.5mm. The depth of the slot is not too deep, if the depth of the slot is too large, the protective layer is easy to break at the slot when being stressed by tension or torsion, if the depth of the slot is too small, the good torsion resistance and tensile deformation resistance of the spiral cutting slot cannot be exerted, and the best torsion resistance effect cannot be achieved.
In an alternative embodiment, the slot 10 is provided with a circular arc 11 at both the front and rear ends. The arc part can effectively avoid stress concentration at the tail end of the slot, and avoid tearing at the tail end of the slot to cause the damage of the coupler. In general, the diameter of the arc 11 is 5-8mm, which is slightly larger than twice the width of the slot, so that stress concentration is effectively prevented, and the end of the slot is not torn when the arc is twisted and deformed.
The coupler is of an integral structure, the stability is stronger, the spiral elastomer is arranged in the middle position, a plurality of slots are formed in the protective layer on the outer side of the spiral elastomer at intervals, and the slots are matched with the spiral elastomer to act, so that the torsion resistance and the impact resistance of the coupler are greatly improved, and the service life of the coupler is reliably ensured even if the coupler is applied to a complex working condition environment.
The above embodiments are merely preferred embodiments of the present invention and are not intended to limit the present invention, and any modifications, equivalent substitutions, improvements, etc. within the spirit and principle of the present invention should be included in the protection scope of the present invention.
