S Series Helical-worm Gear Units


 S Series Helical-worm Gear Units


The advantage of helical-worm gear reducers is their simple mechanical construction. They are much more efficient than conventional worm gear reducers. And the S series reducers are quiet in operation.
Suitable for installation spaces where installation space is limited. Use the S series reducers for simple tasks in your machine or plant application.
The combination of worm gear and helical gears is more efficient than a simple worm gear reducer. Sliding friction makes the reducer run smoothly and quietly.

The torque range is from 92 Nm to 4,000 Nm.

Using the modular concept, the S series reducers are combined with AC motors to form S..DR.. helical-worm gear reducers and with servo motors to form S..CMP servo helical-worm gear reducers. You can also select the AC motor or servo motor that meets your requirements separately.


Features


      1. The helical gear-worm combination is much more efficient than a gearbox with a worm gear
2. Low-noise operation
3. Available variants:
o Foot or flange mounting
o B5 or B14 flange mounting
o Solid shaft or hollow shaft
o Hollow shaft with keyway connection, shrink disk, splined hollow shaft or TorqLOC®


Advantages


Space-saving installation:

Torque and speed can be adjusted individually in all 7 sizes.

High efficiency:
Combination of helical gear and worm drive. Much more efficient than general-purpose helical gear-worm reducers.

Low-noise operation:
Torque pulses at the output shaft of linear power transmission
