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.

Optimised solutions for complex motion cycles

Helical worm gear units are used to safely lift and lower loads and are ideally suited for applications in continuous duty. The combination of a worm gearing with an upstream helical gear stage provide the advantages of both gearing types.

helical worm gear by AUMA Drives / GFC

On the one hand, the two stages allow for large transmission ratio ranges, on the other hand, it combines high efficiency levels and torques with highest lifetime and reliability within a compact drive. This is extremely efficient in terms of space, cost and reduced maintenance efforts.

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

The models are available in sizes 50, 63, 80, 100, 125 and 160. 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.
