Louis Luu Posted November 13, 2021 Author Share Posted November 13, 2021 Base finalized...minor fixes to the feet and wire terminal. Will be working on the motor today. 1 Quote Link to comment Share on other sites More sharing options...
Louis Luu Posted November 14, 2021 Author Share Posted November 14, 2021 Got the base done. Need to put wire terminals on the motor...will do that later on. Still need to draw the rotor next. The top rotating mechanism will need to wait till I order the flange bearing to make sure it fits. 1 Quote Link to comment Share on other sites More sharing options...

Louis Luu Posted November 21, 2021 Author Share Posted November 21, 2021 Finally got the bottom done...no more revision. Tweaked a little around the corners to get the correct profile. Also, moved the magnet wire bar and made it simpler to wound wires. 1 Quote Link to comment Share on other sites More sharing options...

Louis Luu Posted November 23, 2021 Author Share Posted November 23, 2021 The top mechanism where the belt drive sits on actually has a square peg that locks onto the top where the blade spins. 1 Quote Link to comment Share on other sites More sharing options...

Richard Daugird Posted November 24, 2021 Share Posted November 24, 2021 What CAD are you using? Can a .dwg file from AutoCAD be fed directly into the 3D printer?

I know different machines use different files. Some for CNC, some for laser cutting. .stl files are used for 3D printing. Quote Link to comment Share on other sites More sharing options...

The pulley is a tad bit hard to adjust without the actual parts in front of me. I will probably print the bottom portion first. The top mechanism is really complicated.

Louis Luu Posted November 26, 2021 Author Share Posted November 26, 2021 I've been reading the patent drawing...it talks about a set screw "J". Where the heck is the letter "J"? The top disc is supposed to be a brake disc for slowing down the fan and not supposed to turn...hence the square hole. The letter "f" is supposed to have rubber for traction and reduce noise. I got the proportions right...but drew the square holes in the wrong place. Also, d' is supposed to be one entire piece according to the description. Now comes the wild part. The setup is supposed to be for 1 blade, 2 blade, 3 blade and 4 blade according to the patent description. 1 Quote Link to comment Share on other sites More sharing options...

Bill Dunlap Posted November 26, 2021 Share Posted November 26, 2021 OK, four blades. Do it! Also, I read this to say that the blade assembly ROTATES while the blades spin, right? There's a friction adjustment at the very top to set the rotation speed. Cheers, Bill 1 Quote Link to comment Share on other sites More sharing options...

Cheers, Bill Correct...the thing at the end of the shaft...round wheel has rubber insole for friction. I am going to send this off for printing while I redraw the top mechanism now I understand what the patent was referring to. Maybe I should have read it first before drawing it. I decided for the meantime, I am going to make the top cover plate with the logo. They did make a non-oscillating version. I think the most I will make is a 2 blade and a 3 blade version. 4 blade would be overkill?...I don't see any clearance for the blades? 1 Quote Link to comment Share on other sites More sharing options...
