Gear Couplings TNZ ZCAF / TNZ ZCBF

Intermediate shaft and rigid counter-ﬂanges

The model RINGFEDER^® TNZ ZCAF is composed from the coupling halves of the coupling TNZ ZCA and is complemented by an intermediate shaft and two rigid counter-ﬂanges. If required, the torsional stiffness of the shaft can be tuned to the dynamic behavior of the drive line. In addition, the intermediate shaft, which serves to accommodate longer shaft separations, can be mounted and dismounted radially with- out having to move the connected machines.

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.

Materials

High-grade tooth profiles and grease with ultra high-pressure additives guarantee low-restoring forces and a long serviceable life. The material used is forged steel with an apparent yielding point of at least 335 N/mm². Special materials can be used for further specific applications. Sealing is carried out using O-Rings of synthetic rubber. The housings are centred and held together by fit-bolts and self-locking nuts.

Temperature

The use of special seals permits the temperature limit to be raised to 120 °C.

Balance

At peripheral speeds upwards of 30 m/s it is advisable to dynamically balance the coupling.

Special applications

If greater misalignments are anticipated at higher speeds and torques, an examination is necessary, performed with the assistance of a special computing programme. This is independent of the determined size. The value T_Kmax may not be exceeded in any state of operation (start-up, electrical short circuit, blocking, etc.).
