This was Nazi technology - it powered the Tiger Tanks and Panzers. It was damn-near the death of the world because it could handle a momentary 300% overload, so when you exploded shit on those tanks, they kept on coming.. by contrast, our "helical gear" transmissions would shit-the-bed and leave our boys as easy targets. The Germans shared the technology with Japan and after we nuked the crap out of the island, only ONE gearbox manufacturer was left: Sumitomo. And what was their signature product? You guessed it, the cycloidal gear drive. It took-over Japan because it was the ONLY option, then it came to the US and is the MOST popular style of gearbox, today. The "Sumitomo drive" is the most popular and the one he shows in MOST of the video (with the smooth curvy lobes on the wheel), but if you look closely during his conclusion, he shows a "flat tooth" version which is the preferred style of Shimpo Drives. The founder of Shimpo, a man named Okuda (spelling? and I do not remember his first name), who I had the pleasure of meeting once, developed that style for Sumitomo, but it was rejected, so he started his own business using that style which still enjoys much success today - the Shimpo Style reducer removes the need for 2 supporting bearings on the output shaft and almost doubles the over-hung load capacity of the unit.
Cheers for the clear visual synopsis!
this was a good complete summary
that's what i was lookig for .thanks for the video
Does it have a sinosoidal component like those in harmonic drive?
yup. thats the thing
