KTR Gear couplings / Curved-tooth gear couplings
KTR torsionally stiff gear couplings operate according to the curved-tooth gear principle. As a result edge pressure in the spline is avoided with angular and radial displacements by the gear coupling. BoWex curved-tooth gear couplings with the material combination of steel hubs and polyamide sleeves allow for maintenance-free permanent operation with severely beneficial coefficients of […]
