It has about 6 solid contact points....taking in the fact that these are plastic gears...I would bet it's pretty strong for its purpose. I'm more worried about the wear of those belts in those extreme angles...
@@b03tz At the end you can see wear on the edge of the belt. And if all 6 points of belt contact mesh properly, it's either a miracle, or very careful design.
@@criznachhow would that be a miracle? If you design a GT2 gear, it would be obvious those teeth all align. Only problem is that the belt goes straight for a tiny bit that might pull on the teeth. The belt wear is a bigger issue I think!
@@criznachfor sure for sure! And in that case I guess if he calculated the rollers so that exactly 1 or 2 teeth are “skipped” it would be quite amazing!
@@gryn1s In commercial joints like in Kuka arms, the belts twist like this, but the length of the twist section is much longer. This creates a smaller ratio between the required outer length on a helix to the required center length of a straight line. Thereby reducing wear on the belts.
