Elastic pipe couplings are used in low power drives because their application is limited due to loss of section stability under loading of comparatively low rotational moment. This results in significant performance degradation of properties of such couplings. In order to improve section stability and, therefore, to increase the transfer moment, it was proposed to fill the pipe’s internal space (between shafts to be connected) with narrow metallic rings which were mounted with some tension. Changing the number and height of rings could lead to changes of the coupling properties. A coupling with an elastic metallic assembly mounted in the pipe’s hole was developed for operation under high dynamic loads. A patent for invention of the Russian Federation was received for this coupling.
