Emmett's Bearing Remix

thingiverse

Once I finally printed one of Emmett's bearings, I was really impressed by the overall function. This version has a couple of distinctive elements. First of all, the normal involute gear tooth was replaced with a home-grown rounded tooth that mimics belts drives more than normal gear profiles. The second change is the replacement of the herringbone pattern with a sinusoidal pattern. One can ask "why?"... And I will answer to say it is simply an idea that may or may not have advantages. Style points are always good too :) As to the design; it is a little larger that Emmett's bearing but the tooth-count is the same. It also has the same center hex size. Overall it is a bit thicker and slightly larger in diameter. I wasn't going for direct replacement. Overhangs are managed to 45 degrees and tooth-clearance is set to 0.25mm.
