RINGFEDER TNZ Gear Couplings
RINGFEDER TNZ gear couplings (formerly TSCHAN POSIFLEX) are all-metal torsionally rigid gear couplings enabling the transmission of the highest torques with small installation dimensions.
RINGFEDER TNZ gear couplings have special gearing, which allows only a small backlash and smooth running over the entire speed and torque range. Grease lubrication ensures low maintenance while being able to compensate for radial, angular and axial misalignments.
Couplings Fields of Use
RINGFEDER TNZ gear couplings (formerly TSCHAN POSIFLEX) are designed for the transmission of the highest torques in all industries.
They are used mainly in the drives of conveyor systems, rolling mills, mixers, cranes and other highly stressed drives in steel mills, in the paper, chemical and other industries.
The couplings are available in various series and designs.
- Torsionally rigid couplings made of forged steel
- Compensates for angular, parallel and axial shaft misalignments of the connected machines
- Special seals permit temperatures as high as +130 °C
- Available with double-piece (ZEA/ZEB) and single-piece (ZEH) housing
- Max. finished bore – 320 mm
- Nominal torque of coupling TKn = 290,000 Nm / TKmax = 580,000 Nm
- Operating speed to nmax = 5,000 1/min
