The Hirth coupling is a machine component that connects and precisely positions shafts, wheels, disks, and cranks in many areas of mechanical engineering to one another. They can be manufactured from most metals and from plastics. In addition, the Hirth coupling is a connection component that is easy to release.
But there are other applications as well. For example, complex single-piece forged parts can be replaced with several less complex ones. With Hirth couplings, these components can be connected with high strength and with precision.
Voith manufactures the Voith Hirth coupling onto your components – up to a diameter of 1,600 mm and with lead times of just a few working days. Voith can also offer key engineering services during the design of your components. They can provide you with a consultation during the design stage and perform the calculations needed for your Hirth coupling. If you wish, Voith can also take charge of quality assurance tasks for you.
From the very outset of your product development, you have a reliable partner with professional expertise in the design and manufacture of Hirth couplings. That saves you a great deal of time and money during product development and during later stages of production.
