strain wave gear (RL-S) vs. cycloid gear (RL-C)
Martin Raak | 28. June 2017
The strain wave gear is available as a product in the size RL-S-17 and RL-S-20. RL-S-30 is a prototype and still in development.
The cyclo gear can be an alternative in future and is not available as a product yet. The sizes 17 and 20 are currently in development.
Both types of gears contain a coaxial in- and output axis (different from RL-D worm gears), they consist of three similar components:
- An outer (static) toothed ring
An inner toothed ring (rigid in the cycloid gear, flexible in the SWG)
A drive (an excentric in the case of the cycloid gear, the wave generator in the SWG)
