Voith Hirth Couplings in Gas Turbines and Compressors – Operationally Reliable, Self-Centering and Easy to Assemble
Gas turbines and turbo compressors are subjected to extreme loads. They need to ensure maximum reliability despite the high pressure and extreme temperature differences. Hirth couplings from Voith are used at various key points here, for example, between gas turbine disks or as a connection between the impeller and pinion shaft. They ensure high precision in both axial runout and concentricity and reduce the load on the bearings due to their precise, reproducible centering. They also reduce the rotating mass in comparison to force-fit flange connections.
Shafts and their seals in the driveline of coolant pumps need to be regularly maintained. In this case, Hirth couplings provide the option of combining several shaft segments into arrays up to five meters long. It is not only considerably more cost effective to manufacture the small segments; they can also be assembled very quickly or removed individually. Hirth couplings guarantee concentricity precision of better than 0.05 mm even in arrays and retain the original balance even after being disassembled several times.
Leading manufacturers of gas turbines, turbo compressors and turbo fans rely on the safety and repeatability of Voith Hirth couplings.
