I dunno?! I've spent my whole career as an electrician in huge machinery facilities. The lubrication for gear boxes is centrally located, pumped out to all gearboxes, maintained in temperature (not too cold and not too hot), and the more the precision of motor speeds to the output rpm of that gearbox, (100 corrections per second) the more things get very, very, very, dicey. Better be careful because that motor will be hotter than Satan's furnace after a few hours of that application connected to a VFD or servo. Several servo motors, one for each axis, connected to each other in motion control software like Allen Bradley Kinetix Drives would seem a whole lot smarter to me.
One motor with one output shaft connected to a dozen or so mechanically linked gearing applications has always been a hard crash disaster setup IMHO. To me this seems like a step backwards in technology.
