Before trying to reduce mechanical noise, it is important to know where the noise is produced.
The crank drive makes two different kind of noise.
The gears are installed in the open air without good lubrication.
The backlash in the con-rod makes a knocking noise when changing direction.

The K-W-D , can be made less noisy by enclosing the gears in a lubricating box.
There is no backlash in the Wiggle-Drive rotating power transmissions. .
