message: It isn't clear how it works, so I've added a Cleanup tag. Biscuittin (talk) 22:58, 29 December 2007 (UTC)
replies: text: This was removed by robot shortly after being added. If you made the animation yourself, the best thing to do is probably to upload the animation (details at Wikipedia:Upload), with an appropriate license (which you can select), and a description that includes the phrase "I, the author of this animation, hereby release it under the (name of license) license.". Then you can link it with an Image: tag. --Christopher Thomas (talk) 06:24, 19 April 2008 (UTC)

thread_title: Clarification and diagram

message: Does Harmonic Drive LLC have a patent monopoly on harmonic drives or something?  If not, the second paragraph of the History section is irrelevant/superfluous and should be removed or moved, as the subject of this article is not a corporation but a technology. 206.57.41.114 (talk) 18:41, 17 February 2009 (UTC)
replies: text: It is a patented device that apparently is only manufactured by 2 groups, so unfortunately any description is likely to sound like an advertisement. I cleaned up the introduction so that it sounds a bit less like an advertisement and more like a useful device. Also added some references to its robotics & aerospace applications and its weaknesses, since I have used them on robots before and was told that they may still have issues of degrading over time if it experiences shocks on the output shaft. --Shervinemami (talk) 16:57, 24 May 2010 (UTC)

thread_title:  Questions 

message: Regarding your edit:, I would like to explain that this is not promotion. Behind this correction there is a legal problem. Harmonic Drive is a registered brand mark in Europe as well as in the US-market and not allowed to use it as a generic term (see also the german side of wikipedia/Harmonic Drive. The only reason I added the information that there is a company called Harmonic Drive LLC is that there have to be a connection to the key word "harmonic drive" and the explanation why sometimes it's called a harmonic drive gear. There are more companies who produce such gears and they call it all (more or less) strain wave gearing. Also in the patent of the inventor, Musser, he speak about the strain wave gear.-HDSC (talk) 20:00, 10 May 2012 (CET)  — Preceding unsigned comment added by 217.17.17.170 (talk)  
:That is interesting. Do you have any evidence supporting your claim; by which I mean evidence that does not originate with your company? --John (talk) 16:54, 11 May 2012 (UTC)
replies: text: far as i know "Harmonic Drive" is much more common so i would recomend to switch it to (known also as/originaly named "strain wave gearing"). Its a very common problem in technology to sort out uncommon names unfortunatly. See also Hexapod/Stewart platform. --Kharon2 (talk) 00:09, 17 February 2013 (UTC)
