Hirth Couplings on Customers` Components
From Hirth Couplings
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.
We manufacture 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. We can also offer you key engineering services during the design of your components. We can provide you with consultation during the design stage and perform the calculations needed for your Hirth coupling. If you wish, we 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.

- We offer you a comprehensive range of 'all-round' services: Design consultation, calculation, production and quality assurance – all from a single source. You are guaranteed an expert partner in all matters relating to Hirth couplings.
- The Voith Hirth coupling offers zero backlash and a high torque capacity. This allows very high torques to be transmitted by relatively small diameters. Thus you save on valuable installation space in your designs.
- The high degree of indexing accuracy and repeat accuracy make Voith Hirth couplings an ideal positioning element – for example, in the machine tool industry and in general mechanical engineering. This enables you to position your workpieces or products with positive locking and with highest precision. You can then produce parts to the highest quality standards and achieve maximum productivity levels.
- With a Hirth coupling, you have an easy release connecting and positioning element. Assembly and disassembly are quick and easy. That lets you save on costs when assembling your machine and again later during maintenance, repair and service work.
- During assembly, the components are self-centering. You save the cost of additional alignment work.
- The disassembly of the coupling requires only minimal space – just enough clearance for the tooth height. That simplifies maintenance and repair and reduces costs.
- We use specially developed processes to mill and harden the gear teeth. The Voith Hirth coupling has a very long service life and is maintenance-free. This reduces the life cycle costs of your machine.
