Backdriving efficiency and self-locking of worm gears
Backdriving efficiency and self-locking of worm gears
(OP)
I have the backdriving efficiency of a two-stage worm gear reducer from the manufacturer as being 2%. I know that by definition a self-locking worm has a backdrive efficiency of zero. Is there any rule of thumb based on the value of backdriving efficiency to which you consider the gearset to be self-locking in practical use? (ie - would the above reducer be considered self-locking in practice?)
Thanks.
Thanks.

In metal worm gear systems that holds pretty well, but in plastic worm drives, the mesh runs-in nicely, and what did not backdrive will backdrive in time especially with vibratory loading.
