Rigid coupling TNZ ZCH

geartorsionally rigidshaft

The RINGFEDER® TNZ ZCH, comprising one-piece casing with O-ring supports on both sides and two hubs on the TNZ ZCA. Combinations available with long hubs (ZCHU and ZCHUU). Product 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 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. As a result, the hubs can move spatially within the housing and thus compensate angular, radial and axial shaft misalignment of the adjoined shaft ends within specified tolerances. Depending on coupling type and size, the standard toothing permits an angular misalignment of up to 0.5 degrees per toothing-plane and an axial movement of several millimetres. The max. possible radial shaft displacement is dependent on the distance between the two toothing planes. Other toothing geometries can be used for further specific applications.
