Couldn't the same be achieved with a set of 45* helix-angle gears? - That is, transfer power 90* off-axis?
He is not at 90 degress here. Said it was what 75 degrees?
Whatever the application NEEDS is the actual point.
Historically, "universal solution" HAS BEEN to come in at right-angles, then rotate a
second set of right-angle gears at any arbitrary angle 'round that output shaft. Works well, is all over the place for hundreds of years.
But takes more space ... and two sets of gears, rather than but the one.
3-D is one of the most USEFUL of game-changers since casting was expanded from holes in the ground and sand molds to precision metal dies and alloys that came out ready to use.
It is also perhaps the
fastest improving technology yet introduced since the Industrial Revolution began.
Since the same CNC tools aready proven underpin it, it can also allow production at arbitrary distances from design, R&D, and testing.
IF.. mankind can avoid obliterating ourselves long enough to reach out for the stars?
3-D printing.. or something several steps yet BEYOND it.. will play a MAJOR role.
