Stupid title.. this is NOT a harmonic drive but a planetary gearbox made by a company that was dumb enough to name them self after the first product they produced (they probably thought they were smart by doing that)..... So it's a planetary gearbox made by a company called harmonic drive... The same as if a company called them self Diesel motor and they started to produce electric motors

@b03tz 11 ай бұрын

I think Harmonic Drive is a brand name...and what you are referring to is a strain wave drive system; systems they and other companies produce.

We've a servo-drive("DCJ-055-09). We connected it with the motor and powered it up. And we tried to set it up using HDM software through RS-232 communication. But it didn't respond. We rechecked all the connections for several times but nothing solved. The status led always green/blinks, it didn't get the status of solid green. Why would this problem happen? It will be so helpful if you kindly have an answer to this problem.

It still has an outer ring gear and an inner compliant gear. Any clearance between the mating gear teeth will lead to backlash. This can occur through wear and tear from daily use; not just manufacturing tolerances. You can't state with absolute certainty that backlash is zero in practice. It might just be small enough to ignore .

It's been "working" since the 1950's. I have had a number of engineers tell me Mr. Musser was a genius. During his lifetime he was approached about writing a book about his inventions. He refused, telling the writers he had no desire to become famous. Plus, much of his work is still classified by the government.

Does anyone else find it odd that this beautifully designed graphic does not actually show the output turning? It literally shows the input drive spinning inside a stationary ring. To truly demonstrate this mechanism the output should be turning at the correct ratio to the input.

@HarmonicDriveLLC 4 жыл бұрын

If you look carefully, you should be able to see that the flexspline is turning very slowly (due to the high ratio)

I'm really curious as to when the R&D will finish the Abacus Drive (pure rolling cycloid). It's beginning to look as though the production is being stalled due to Patent hoarding. If some sort of video can be made to showcase where things are at with that product, I'd be most appreciative. Having some surety of production, available sized design and a timeframe for purchase can give the customer a place to plan things from. Many thanks for any time given to attain an answer!!

Torsionally stiff yet radially compliant... hmmm... How much energy is lost in flexion of the flexhub? It is conceivably a spring. Possibly that helps. What about metal fatigue?

@Averell64 4 жыл бұрын

I doubt metal fatigue is an issue here - if it's made out of steel with a cubic room centered grit you can find a max stress where you will have an infinite amount of cycles as long as you don't go over that stress level... If its a metal with a cubic surface centered grit it's a little harder cuz those metals will break at some point but even there you can pretty reliably find a stress level with which you can reach a couple billion cycles (that would be with aluminum and certain non-rust steels like V2A for example) Ps: some translations might be a bit rough due to me not knowing the proper technical terms in English but I hope it gets the point across.
