Inkoma IKT Inkoturn encoder couplings from Francis and Francis
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.
