In order to achieve the above object, a preferred embodiment of the present invention includes an elastic body for engaging between two sleeves of a coupling, the elastic body having a ring body, and the outer ring surface of the ring body is formed with a plurality of outer rings The protruding teeth are characterized in that each of the protruding teeth is formed with at least one hollow portion, and at least one supporting piece is formed in each hollow portion, and the supporting piece is connected to the two side walls corresponding to the hollow portion. In a preferred embodiment, the hollow portion is a through hole and is connected to both ends of the convex teeth corresponding to the two sleeves of the coupling. In a preferred embodiment, the hollow portion is a recessed hole and is formed at one end of a convex tooth corresponding to one of the sleeves of the coupling. In a preferred embodiment, the hollow portion is a recessed hole and is formed at both ends of the protruding teeth corresponding to the two sleeves of the coupling. In a preferred embodiment, the thickness of the support sheet is equivalent to the thickness of the side wall of the convex tooth. In a preferred embodiment, the convex tooth is formed with at least one projection at one end of one of the sleeves of the coupling. In a preferred embodiment, the convex teeth are respectively formed with at least one convex piece at opposite ends of the two sleeves of the coupling. M410813 • By this, the elastic structure of the present coupling can pass through the hollow portion of the convex tooth and the support sheet structure, so that the cooling and contraction conditions of the elastic body during molding can be easily controlled without shrinking the sink (Sink Mark). The phenomenon is generated, and the speed of cooling can be accelerated to facilitate demolding, thereby achieving the effect of improving production efficiency and output. Furthermore, the creation is applied between the two shafts and sleeves of the coupling. When the coupling is used to transmit the power of the two transmission shaft systems, it can transmit the shock absorption, torsion rigidity and resistance of the elastic body. The structural characteristics of the torsional strength prevent the shock of the two transmission shaft systems and cause damage, and achieve the effects of cushioning, damping, and wear resistance. [Embodiment] In order to make your reviewer understand the purpose, characteristics and efficacy of this creation, the following specific examples are used, together with the attached drawings, to give a detailed explanation of the creation, as follows: As shown in the figure, the elastomeric structure of the present coupling, the preferred embodiment thereof comprises: an I elastomer 2 for engaging between the two sleeves 1 of the coupling; the two sleeves 1 The power shafts are respectively connected to the two transmission shafts, and a plurality of claws 11' are respectively disposed on the corresponding end faces of the two sleeves 1, and when the corresponding end faces of the two sleeves 1 abut, the claws are 11 can be engaged with each other for transmission; the elastic body 2 has a ring body 21, and the outer ring surface of the ring body 21 is formed with a plurality of spaced-apart convex teeth 22, so that the elastic body 2 can be sandwiched between two Between the sleeves 1, and the respective teeth 22 are respectively placed between the two jaws 11 of the two sleeves. The present invention is characterized in that each of the convex teeth 22 of the elastic body 2 is formed with at least one hollow portion 23, at least one support piece 24 is formed in each hollow portion 23, and the support piece 24 is connected to the corresponding two corresponding hollow portions 23. 5 M410813 The side wall 25' thus forms a honeycomb-like structure inside the convex tooth 22. Preferably, the hollow portion 23 of the protruding tooth 22 is implemented as a perforation, so that the through hole communicates with both ends of the convex window 22 of the corresponding two sleeves 1 of the coupling, and is formed in the through hole. Supporting sheet 24 as described. Referring to the second to fifth figures, the hollow portion 23 can also be implemented as a recessed hole and formed at one end of the tooth 22 of the corresponding coupling in which the bushing i is formed, or respectively formed on the corresponding coupling shaft The (four) of the convex teeth 22 of the two bushings 11 are thus formed with the support piece 24 in the recessed holes. Further, as shown in the third and fifth figures, in order to make the elastic body 2 more uniformly cooled when the mold is formed, the thickness of the cut (4) is equivalent to the thickness of the side wall 25 of the convex tooth 22, so that the structure can be made Each part is uniformly cooled to prevent the occurrence of shrinkage depressions (SinkMark) during cooling. Referring to the fourth and fifth figures, the _ can be formed at the end of the coupling 22 corresponding to the sleeve 1 at least - the lobes 26, or the two corresponding to the two sleeves 1 The ends are respectively formed with at least "protrusions 26", and the convex particles 26 of the two adjacent convex teeth 22 are misaligned with each other, so that the two sleeves i can be received by the convex particles 26 with a meandering pitch, thereby ensuring that the two transmission shafts are tied to each other. Electrical insulation and omnidirectional angular deviation adjustment capability. Further, referring to the fourth and fifth figures, the present invention is to make the elastic body 2 release smoothly, which is the hollow portion of each of the convex teeth 22. A draft taper is formed to enable the elastomer 2 to perform the demolding action by the draft taper. By the improved elastomer structure of the present coupling, the hollow portion 23 of the convex teeth 22 of the elastic body 2 and the structure of the material 24 can be transmitted through the respective portions of the convex teeth 22 and the thickness of the ring body 21, so that the entire elasticity is achieved. When the body 2 is molded, the cooling and shrinking conditions of M410813 are easy to control, the phenomenon of Sink Mark is not generated, and the cooling speed can be accelerated to facilitate demolding, thereby improving the efficiency and productivity. Furthermore, when the present invention is applied between the two sleeves 1 of the coupling, and the coupling is applied to transmit the power of the two transmission shafts, the shock absorbing property can be transmitted through the structure of the convex teeth 22 of the elastic body 2 The structural characteristics of torsional rigidity and torsional strength prevent damage caused by sudden-seismic phenomena of the two transmission shaft systems, so that the effects of cushioning, shock absorption and wear resistance can be further achieved. • In summary, the elastic structure of the creative coupling actually enables the elastic body to effectively absorb the impact load, and its structure is also suitable for mass production, so it has been seen that the efficacy is improved, and its application is also The first innovation, should be in line with the new requirements, for this purpose, apply for a new type of law, but please ask the bureau to give a detailed examination and grant a patent, the real sense of virtue.
