robolink joints in format adjustment

We not only build robots and robot parts, our joints are also used f.ex. in format adjustments. The video link shows an example from a packaging machine, the 2nd film shows an igus demo unit. In this case, the RL worm shaft can be coupled from one joint to another. USPs: running dry, light weight, modular ! ADJUSTMENT VIDEO

robolink designer: design your robot online

with our new robolink design tool, you can design your individual robot and operate it easily. NEW feature: you can see the max. payload and reach directly, depending on your design! Attached is a little instruction how to make use of this (we need your confirmation of exclusion of liability before it is available – sorry).

Output Encoder for RL-D / RL-S

We supply 2 options of encoders for our joints / joint arms.

Option 1 (our Standard before HMI 2017): Motorencoder plus Ini switch for 0-point reference on the joint output (PRT bearing)

Option 2): Output encoder on the PRT bearing of the joint. This is our own development, we use a magnetic ring plus Encoderchip on the output with an aditional magnet and Hall Sensor as reference point. Please find attached a description of the output encoder attached in GER and ENGL. Advantage: less cables, higher resolution, more accuracy for the arm.

strain wave gear (RL-S) vs. cycloid gear (RL-C)

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)
