worm helical gear units
Elevator gear units – a safe bet
worm helical gear by AUMA Drives / GFC

Whether as a passenger elevator or as a stage drive at the theater – our worm helical gear units are the right choice reagarding smoothness and low-noise performance.

The first high-speed gear stage is implemented as worm gear stage ensuring homogeneous and low-noise torque transmission due to the outstanding noise absorbing properties and protecting the subsequent transmission elements from load peaks.

The second stage consists of two helical, low-noise precision spur gears combining premium efficiency and soft start-up behaviour.

AUMA Drives worm helical gear units are operable in both rotation directions. Our worm helical gear units are provided for many connection and fastening options.

The models are available in sizes 97, 118 and 150. Technical data on each size is provided on request.

The basic variant type SSVA can be extended by drive and motor flanges, covers and many further options, such as slip-on output drive shafts.
