Output coupling with rubber elements

prototype

The output coupling with rubber elements is designed as a two-joint coupling to allow radial displacement between the connected shafts. Both joints are realized by means of rubber segments, each side of the coupling being realized by eight elements which are connected to the middle carrier and the outer carriers. Easy assembly is achieved by a conical connection, which allows the elements to be prestressed so that their main load character is tension. Tensile stress of the elements is possible thanks to the construction of the individual elements, where the supporting part is a textile fiber, 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 of the fiber. This construction significantly affects the service life of the elements, as the used natural rubber has a fixed maximum service life. Emphasis was also placed on the cohesion of rubber, textile fiber and metal. Due to the achieved results of the functional sample, the design of the prototype output coupling with rubber 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.
