Hi Michael,
Many thanks for the detailed reply.?
Here is my mechanical setup - I have the reverse worm setup with time gear attached directly to the shaft of the worm. The larger gear is 60 and the smaller is 16.
The aluminum parts form an arrangement, which works as OPW. I drilled and tapped the holes in the bearing blocks in order to make the whole thing as one piece.
So I don't have an Oldham coupler and there is no possibility of misaligning the motor and worm shafts.
I have ABEC 7 bearings and I also tried the Belleville spring, it did not help.
I also tried swapping the worms, looks like it does not help, based on few minutes of testing, before clouds rolled in.?
I have brass worms. I wonder if I should buy new worms.
Right now I am running out of ideas...
Alex
