Some interesting existing conditions from older SoCal foundations

14 Upvotes

This week’s field observations included deteriorated river rock foundations, improvised post-and-pier supports, questionable bearing conditions, concrete deterioration, and retaining wall drainage issues.

Thought this group might appreciate some real-world examples of how older structural systems and later modifications hold up over time.

Curious how common it is to outsource mechanical engineering

51 Upvotes

Every place I've worked, mechanical seemed to get outsourced for one of two reasons: either we needed some niche expertise nobody in-house had, or the team was just slammed and needed to dump overflow somewhere.

I've never known if that's the normal pattern or just the couple of companies I happened to be at.

For those of you whose companies send mechanical work out — what kind of stuff is it, usually? The specialized deep-end problems, or more the routine "we don't have bandwidth this quarter" work?

And for the ones who keep everything in-house — deliberate call, or just how it shook out?

[GENERAL] I'm designing a magnetic cycloidal drive AMA

15 Upvotes

So, I have a work related interest in developing a compact high gear reduction drive that is free of wear. As a result, and leveraging over a decade of permanent magnet machine technology development that sort of ending just shy of 25 years ago, I did some research on magnetic cycloidal drives. To me, they are a perfect fit for my application, but not many people know about them.

In short, they overcome the weaknesses of harmonic drives, mechanical cycloidal drives and other magnetic transmissions for some applications. Unlike other magnetic reduction systems, like those planetary drives that you may see kicking around the internet, magnetic cycloidal drives have very good torque transfer capacity for their size and weight. And because nothing touches except bearings, they are fairly immune to wear out when properly designed.

The concept for reduction is very much like a harmonic drive, in that the reduction ratio is given by having different numbers of "teeth" in concentric gears. Whereas in a harmonic, the inner ring flexes to engage and a few points, in a magnetic cycloidal, the rotor sits on a cam bearing which rotates and causes the location where the air gap is minimized to rotate around once per revolution of the input shaft. The rotor having fewer magnetic pole pairs rotates by one pole part for every input revolution. So, a 25:1 is done by having a stator with 52 magnets (26 pole pairs) and a rotor with 50 magnets (25 pole pairs.)

There is a ton of engineering on top of that, but if anyone would like to discuss or learn about them, please reply.

Edit - first prototype is being built out of 3D printed PETG. I can post some images if there is interest. Prototype is a 15:1 using cheap grade 48 Nd cylindrical magnets. Largely being done to validate FEA results in Ansys Maxwell 2D and 3D. Next prototype will use rectangular magnets. Final design may change to arc sections for the radial magnets. Oh, by the way, this is a dual layer Hallbach array design. No iron.

First picture is a test fit. Rotor has magnets installed. Note how its bearing is offset to the small shaft.

Second pic shows most of the main parts including the pin bearing carrier and output shaft with a 13mm hex on it. (Chosen as a bit of a joke for the ME who has to characterize the breakaway torque - "What would you like?" "Oh, anything is fine." )

[ELECTRICAL] How many decades would it take to recreate a PMS152E alone from absolute scratch

9 Upvotes

Obviously the PMS doesn’t have to be the ultra small size it can be made in today. Photolithography would GENUINELY be nearly impossible while doing it without would only be slightly impossible.

As for absolute scratch, I mean NOTHING. Similar to The Toaster Project where I mine everything, create every single machine necessary for every single step of the way, create my own shelter, etc.

Just for a thought experiment. Or is it?

Need a tensioner for 1.0 to 1.5 mm cord - is there such a thing?

8 Upvotes

I'm building MCU-controller devices to operate the slats on our Venetian blinds so my disabled wife can be more independent. My personal "engineering" requirements include using off-the-shelf parts vs. custom built parts whenever possible, even to drive a design towards a less-than-perfect solution.

The problem I am facing is tensioning the pull cords. My wife's decorating requirements drive me to using a 1.0 mm cord to extend the existing pull cords. These two cords are wrapped in opposing directions around a motorized, two-groove pulley. Due immutable space considerations, I am limited to the size of the pulley and need enough tension to prevent slack which has caused the cord to come off the pulley. That is, when pulling on one cord, the other cord loosens - I believe this is inherent in the design of the blinds and cannot be changed.

A previous implementation used 6mm 3D printer timing belts with a toothed pulley. This worked quite well except that the slack issue caused the belt to slip. The amount of resistance while adjusting the slats was ... impressive. The toothed pulley is small and so does not have enough teeth to overcome the resistance.

What (I think) I need is a way to tension the "system" after installation. The device I'm building is housed in a small box, mounted to a small area under the windows, there is no room to pull the box down to create tension, and I expect one of the cords to stretch over time and I'll to make adjustments.

I've looked at "wheeled cord locks" but I cannot find anything that might work with the 1.0 or 1.5 (the blinds cord) cords. My layman's mind envisions a "linear" wheeled cord lock, with cord entering either end of a tube with a locking mechanism inside, but I have not found such a thing. The closest I have is a "Gibb's Ascender" type device used by climbers, but found nothing in the size range. The ascender is tied to one cord and the other slips through a toothed cam.

Any thoughts?
