Gear Couplings TNZ ZCAK / ZCBK Type with limited end float The double cardanic versions RINGFEDER® TNZ ZCAK and RINGFEDER® TNZ ZCBK are equipped with a limitation of the end float. The limitation of the end float serves to axially locate a shaft that is mounted on sleeve bearings. he rotor of an electric motor with sleeve bearings can thus be aligned within a desired tolerance range via the coupling to the bearing of the driven machine, so that the rotor remains at its magnetic centre during acceleration of the driving machine. The limitation of the end float constrains the ability to compensate for angular and radial shaft misalignments. In contrast to the TNZ ZCAK with integrated O-ring, the TNZ ZCBK has screwed-on, separate O-ring supports. Characteristics General features Torsionally rigid gear coupling made of high-quality steel Very compact design results in a high-power density Compensates for angular, radial and axial shaft offset Suitable for use in temperatures up to +120 °C if special seals are used Available with split sleeve (ZCA / ZCB - ZCA model range also available in ZCB design) and single-piece sleeve (ZCH) The elastic O-Ring can be replaced without having to move the coupled machines Bores up to 270 mm Torques up to TKn = 195,000 Nm / TKmax = 390,000 Nm Speeds up to nmax = 6,000 rpm General description The RINGFEDER® TNZ coupling is a torsionally rigid twin cardanic gear coupling. Toothing The coupling housings have a straight internal toothing whilst the hubs have an external toothing with a chased variable radius.
