Toothed components

The externally toothed components of the gear unit are case­hardened. The helical­gear teeth are ground.
The high quality of the teeth leads to a significant noise reduction of the gear unit and ensures safe and
reliable running.
The gears are connected with the shafts by interference fits and parallel keys or by shrink fits. These types
of joints transmit the torques generated with adequate reliability.
