Derived from the 'Lineflex' design, the Inkoma IKT Inkoturn encoder couplings from Francis and Francis accommodate larger radial shaft-misalignments (also angular) are accommodated in the acetal resin central 'frog' flex-element, with its parallel Link-Arm pairs (each at 90°) pivoting one end on polished steel drive pins and bending along their length to the other.
>Restoration forces are thus, relatively small and it transmits power efficiently, with high torsional rigidity, backlash-free, at constant velocity. With vibration damping, electrical insulation and anodised aluminium, easy-fit 'clamp-lock' hubs, it is a short, light-weight and thus, high speed coupling. Both 'single' and higher torque capacity, 'double' flex-Element, (longer drive pin) ranges are available.
>Applications include encoders, tachos, resolvers, transmitters, measuring systems, control drives, packaging and paper machines, printers, etc.
