"SERIES N" reducers : Sizes 160 to 500

Presentation

These reducers are available with hollow or standard output shafts with diameters from 70 to 180mm, in casing made of cast iron, GS cast iron or cast steel.

Ratios range from 5 to 60. The fact that they may be coupled together means that an extremely wide range of output speeds may be obtained.

Output shaft diameter from 70 mm to 180mm

Works as a reduction gear or step-up gear

Weight from 130 kg to 2 tons

Options :

Reaction arm
Supporting frame for motor
Multi-positioning for fixing brackets and base plates.
GV and PV coupling
Brake
Backstop
Torque limiter
Slow speed shaft with pins, tangentials or bushes
Mechanical torque control by means of dynamometric damper
Electronic torque control
Electronic speed control
Etc

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.
