Output coupling with rubber elements - hybrid

prototyp

The output coupling with rubber elements – hybrid type is designed as a two-joint, one joint is realized by barrel gear, the other joint is realized by rubber segments. The gear part of the output coupling is realized by means of a barrel toothing, which is a part of the coupling, while the internal straight gear is a part of the transmission device. The gear coupling allows axial displacement with low rigidity. The rubber side of the coupling is made of ten elements, which are connected to the two carriers by means of a screw connection. Easy assembly is achieved by a conical connection, which allows the elements to be prestressed, also so that their load is in tension. Tensile stress of the elements is possible thanks to the construction of the individual elements, where the supporting part is a textile fibre, which is wound between the metal sleeves. The surface of the segment is made of rubber, which has a dominant character of protection of the supporting part – the fibre. This construction significantly affects the service life of the elements, as rubber as a form of natural material has its maximum service life. Emphasis was also placed on the cohesion of rubber, textile fibre and metal. Due to the results of the functional sample, the design of the prototype output coupling with hybrid type elements was retained, but attention was paid to the method of production of individual segments in order to balance the thickness of the rubber layer and change the production process to streamline production and thus reduce production costs.
