Works as a reduction gear and step-up gear

A DURAND or ERMASTER reducer may be coupled as a primary stage

Reaction arm
Motor support
Coupling
Brake
Dynamometric damper, torque limiter
Electronic torque control

Advantages

Silent
The principle behind the way worm gears work, by teeth creeping, combined with a high drive ratio, results in the lowest noise level of all gear transmission systems.

Compact
For many applications, having a compact reducer is essential.
DURAND reducers have been designed to reduce size:

Orthogonal layout of shafts
Hollow shaft assembly
High ratios in a small size

Robust
An extremely rigid casing and the use of high quality components with well sized dimensions ensures extremely robust units.
DURAND reducers can transfer high torque without requiring a lot of space.
