reverse play (backlash) for RL-D

Martin Raak | 11. February 2016

our customers often ask about the backlash (or reverse play) for our RL-D joints. It is obvious, that any worm gear is NOT backlash free.

The backlash of our lubrication free plastic worm gear (usually combined with an aluminium HC worm shaft) can be influenced by temperature or payload. We have now measured the reverse play for different types and sizes of our joints at zero payload. As a result, we measured values between 0,20° and 0,45° on the output side of our joints (at the PRT = “polymer round table”).

We will now examine this more closely and give more detailed informations later. In our updated data sheet we state a reverse play of < 0,5° for all STANDARD and HIGH END joints. Download link for the updated data sheet attached.
