It has become an indispensable machine element. Although it was invented decades ago, the Hirth serration has not lost its relevance, because the requirements of modern mechanical engineering have not changed much - easy installation and high-strength connection are still in high demand.
The Hirth serration is a self-centering, face-end toothing for couplings. It ensures the precise connection of shafts, disks, wheels, and cranks. In machine tools it is especially used as an indexing and positioning element with highest repeating accuracy.
The leading manufacturers of turbo compressors and turbo blowers agree in one point: The connection of shaft and impeller of a compressor must be safe, repeatable and space saving; this is facilitated by a Hirth serration by Voith. |
