i read some more on the ampco 45/63000 bronze. it has really good wear characteristics against N60. much better than N60 to N60. Thanks for the suggestion. Brian
I remember reading somewhere that when the aluminum bronze alloys wear that the particles can become very abrasive. how would this compare to 932 bearing tin bronze?
thank you,
brian
Gear and rollers have to be two parts for the system to be assembled. The rollers actually serve several functions. They radially locate the gears, serve as bearings, and also axially support the system. The gear bearing structure can inherently support some level of thrust loading...
Please look at the patent I linked to in the first post. I am Brian, John Vranish (from NASA) is the original inventor of the gear bearing .....
I am in the process of fabricating the first fully functional metal prototype right now. The one in the patent images was fabricated out of plastic...
Thanks again. I'll make some calls after the holiday and price alternate methods of making the gears. Right now cost is approx $1600 for the EDM job out of stainless or regular steel. That's for 6 pinions (2 sets of 3), 2 rings and one sun gear. I am curious to see how hobbing compares. Do...
Also, would adjusting the meshes to full recess action vs the currently balanced recess/approach action effect the backdrivability of the system?

Thank you....
Some more information. The picture is of a mock up assembly I made to test the gear design. For the actual actuator design the face width of the gears is .3in and the PD of the pinions are .783 and .867 for stage two and one, respectively. W/D < .4, is this within reason...
I would like to request some help in gear material choices. I have a lot more information but want to start with a summary of what I am putting together.
I am wrapping up a design for a gear bearing drive actuator prototype. It is a "gear bearing" based planetary gear reducer...
