Re: Swerve Drive Concept
Question: Is this meant to also be the power unit for the entire drive? Or is one of those motors a Mini-CIM? (Or, is this for a 3-wheeled swerve?)

Re: Swerve Drive Concept
It can be a three wheel swerve, or it can be a four wheel swerve with a minicim.

What is the steering motor? |
Re: Swerve Drive Concept
Design looks pretty good. I dig the 8 motor design.
The top orange plate on the module seems overly complicated, from a machining standpoint. Instead of having those little flanges hanging down, why not just bolt downwards through the orange plate into the two side plates? What are you using to rotate the module? And how are you tensioning the chain? It's hard to see what's going on back there. I sort of consider 1640 to be the gold standard of swerve (Well, tied with 1717 maybe :D), and they've really taken the time to iterate, improve their design, and cut out unnecessary things. They also released everything you could want to know online. I'm not saying ditch your design and go with theirs, but they've already solved a lot of the problems for you, so you can learn from their mistakes so to speak ;) |

To keep the chains tight, we plan on putting spacers underneath one side of the lower gearbox plate until the chain is tight. We've done this in the past, and we only had to adjust the shims twice during the season to keep up with the stretching chain. The chain for the swerve module has a calculated center to center distance, and its small enough that it doesn't need tensioning. |

Re: Swerve Drive Concept
I could, but then I would have to move the side plates in a little bit, or make the tabs thinner than the side plates. Also, I don't really know how those right angles could be machined easily.

Re: Swerve Drive Concept
You won't be able to machine the female slots the way they are in the picture (at least not with conventional subtractive manufacturing). What you could do though is do a pair of slots oriented orthogonal to each other (one provides constraint in the Z axis, the other provides constraint in the Y axis, and the screw/surface provide constraint in the X axis). As for the male bosses, you'd clamp the piece in the vice so that the bosses would be sticking straight up, and mill across the top. Not very nice if you've got a long piece (or you'll want to use a horizontal mill). That tab design is generally reserved for plastics cut on a laser cutter.

As long as there are still flats on each side of the boss and hole, there won't be a change in effectiveness. In fact, having the radii in the corners will increase the strength of both parts. (Sharp corners provide a convenient fracture point for the material) |
Re: Swerve Drive Concept
Do you plan on making or buying the bevel gears? They would probably wind up being one of the most machining intensive pieces in this design.

The process of cutting good gears is not a simple one, and it requires some pretty specific equipment, very few professional machine shops even have that kind of stuff. |

Bevel Gear Tube Drive I was asked to cut these high quality bevel gears, for the exact purpose to show that with today's machining capabilities, you don't have to be a gear manufacturer to produce high quality bevel gears. Several of these displays are travelling to Trade-shows and Expos, to highlight the capabilities of the OMAX Waterjet's: "A-Jet" A-Jet Demonstration Video I <3 my job :D |
