TSCHAN® TNZ ZCAU / TNZ ZCBU

TNZ ZCAU: Double engagement design with an elongated universal hub

Compared to the TNZ ZCA types, the coupling model TNZ ZCAU is equipped with an elongated hub, the length of which can be adapted to the plant requirements.

TNZ ZCBU: Double engagement design with a bolt-on O-ring carrier for ease of installation and an elongated universal hub

Compared to the model TNZ ZCAU, the TNZ ZCBU coupling is equipped with an O-ring carrier which facilitates installation by changing the mounting sequence. For mounting the coupling, unscrew the cover and place it on the shaft. Mount the hub onto the shaft, slide the sleeve onto the hub and fasten the O-ring carrier to the sleeve. This way of mounting is advantageous when large couplings are involved. Like the model ZCAU, the ZCBU has an elongated hub the length of which can be adapted to the plant requirements.

General description

The TSCHAN® 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 and lip-seals of buna N. 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 TKmax may not be exceeded in any state of operation (start-up, electrical short circuit, blocking, etc.).

Tolerances and standards

The bore tolerance is ISO H7, if not differently ordered. The bore diameters listed refer to keyways to DIN 6885-1.
