#HARMONIC DRIVE PLUS#

Expect to pay more if you want a complete unit (i.e. From experience, the price tag is approximately 1000 euros per harmonic drive for only the component set (consisting of the wave generator, circular spline and flex spline). They are precise, designed for a long lifespan and have good load/weight ratios. Harmonic drives from the vendor you state are of high quality. You first have to ask yourself if you have a high desire for these properties, because there is a price to pay.

They are beneficial for high precision tasks and various difficult control tasks (such as balancing and walking). More specifically, they take up very little axial space and use only one stage of reduction. Moreover, regarding mass and size, they become more beneficial for higher gear ratios as their size and mass do not scale for higher ratios. The core reason for choosing harmonic drives is desire for zero backlash. If so this seems very affordable and could provide decent precision on part of a robot arm. Thanks for any help, looking for a decent starting point.Д®DIT - I would like to use one of these special gearboxes with a NEMA stepper motor if possible (and if it saves cost) since we have a bunch of those lying around, heh.Д®DIT2 - Curious if this item would actually have some sort of strain wave gearing inside of it. I have little experience with this technology (precision eccentric gearing), but would definitely like to explore it and purchase test equipment to construct a basic arm. Side/related question: would buying from China work out alright or would I not get what I'm looking for (namely: good torque at <1 arcmin backlash)? E.g.

#HARMONIC DRIVE PLUS#

Plus for Harmonic Drives I only found one vendor. What sources would you recommend? Online the sites seem very specialized, gotta go through sales reps, etc, which kind of worries me regarding the prices lol. Arm goals at a glance: 1m total reach, 5kg payload, reasonable speed. How feasible are these for use in a hobby project? I do have several thousand dollars at my disposable to build a 6 DOF arm. After a fair bit of research into industrial robot arms I've learned that a lot of them use components like harmonic drives and sometimes cycloidal gearboxes.
