Flexible Coupling EVOLASTIC
Compact in the axial direction and available in a variety of designs, a flexible coupling widely suitable for motor and engine drive applications.
EVOLASTIC is a highly flexible, backlash-free flexible coupling that allows for the connection of shafts and flanges. The preloaded elastomer absorbs torsional vibrations and shock loads in the drive system. It also efficiently dampens solid-borne sound while simultaneously absorbing misalignments (axial displacement, parallel displacement, angular displacement) that occur between the driving and driven machines. The elastomer, an important component, is shaped into a ring by vulcanizing and bonding rubber and metal. The permissible temperature for natural rubber types (WN, SN, MN) is up to 90°C, while for EPDM types (WE, SE, ME) it is up to 110°C. It is possible to select different rubber hardnesses without changing the size of the coupling. The basic design is broadly categorized into bolt-connected types and plug-in types. Hubs and hubs, or hubs and flanges, can be combined according to the mounting dimensions of the driving and driven machines. This allows for flexible responses to various mounting dimension requirements. *For more details, please download the PDF or feel free to contact us.*
