Convenient and safe:
Worm helical gear units.

Worm helical gear units are proven as driving unit for escalators around the world. Even and low-noise torque transmission of the worm stage is combined with the high efficiency of two helical gears. This results in soft-start behaviour and low running noise which will pay off at high traffic hubs as well as in busy shopping malls.

Basic gear units by AUMA Drives meet all safety-relevant standards such as EN 115-1:2017 and APTA. Both type ranges are available in different versions and nominal powers up to 45 kW. Furthermore, our engineers configure complete drive systems with integral motor, brakes and sensors according to customer requirements.

Most escalator gear units by AUMA Drives are based on worm gear units. High-speed worm gear unit stages ensure even and low-noise torque transmission while providing optimum noise absorbing properties. The downstream helical gear pair caters for high efficiency and soft start behaviour within the gear unit. Finally, the downstream transmission elements act as additional protection against load peaks.

3 to 4 basic sizes between 100 and 212 mm centre distance available, depending on the applications

2 or 3 transmission ratios can be configured

High efficiency at nominal powers between 25 and 45 kW

Lubricant sensors as an option (temperature, filling level)
