Worm-helical gear units

Low-noise gear versions are the real challenge in stage engineering.

No matter if the curtain falls, the scenes are shifted or the stage setting is changed. The GFC „Whisper gear“ has a noise level of less than 55 dB(A) when under load.

This is ensured by smooth interaction of gear, electric motor, dual brake and incremental encoder.

Due to its excellent noise absorbing properties, the first high-speed gear stage is implemented as worm gear stage.

The second stage consists of two helical, low-noise precision spur gears.

Combined with spherical explorer roller bearings, they guarantee unimpaired cultural pleasure.
