Gear Genorater

[Alexia Borson]

Nonethelessmy coming weekend is all about gears, making a camera pan widget that slows a driven stepper to 1/4 rpm for time lapse. Yes, I know you can buy kit to do this but not the same as making it yourself, you know, with working gears!

Hello,

During recent work with inventor we encountered a serious problem with the spur gear generator. The generator appears to have broken down and does not calculate no matter the input.

As it is opened the error is present straight away. We tried changing the parameters and goals of calculator, but nothing changed. It appears that the program has saved some invalid data which blocks the calculation and terminates the whole generator work.

Hope you could give us some insights or a solution.

sorry that you see this problem. Could you try to remove default values for this generator. The values are stored in this file: "c:\Users\\AppData\Roaming\Autodesk\Inventor 2019\DesignAccelerator\Defaults\CAGearsSpur.Metric.xml"

The other generators seem to work just fine, all calculations are correct and show no errors. The spur gear generator shows errors and incorrect data (as in the previously posted pictures) as soon as the generator is opened. One peculiar thing I noticed about this error is that when I set the generator option to calculate inner toothed gears it changes the dimension between gear axes to a smaller value (let's say from 100 mm for outer to 60 mm inner as it's supposed to). But when the option is set back to outer (the checkbox is unchecked) it does not recalculate the axial length and gets stuck of the lower number.

Hello again,

At last, the solution helped! The removal of the original file once again seemed to have no effect on the performance of the generator. However, once the new settings were inserted, the software seemed to instantly work as it should. Thank you for not turning the problem down. Your help is greatly appreciated.

Sincerely,

Rytis

Hello again,

The problem appeared again. However his time replacing the CAGearsSpur file does not help. I also noticed that other generators seem to not works as well. So far I have tried deleting all the defaults files I could find, but with no luck. I desperately need for the accelerator to work this time.

I've been using Open SCAD to design and print simple adaptors and other useful parts (having failed dismally to get a grip of other popular 3D CAD programmes). I am very much a learner in this field but have found SCAD to be something I can learn in very small steps (which in my case is absolutely necessary).

However, this is clearly a very powerful design tool in the hands of others better qualified than myself. A new feature of Open SAD is the 'Customiser' feature that essentially lets a user enter parameters via an on-screen form. Someone clever has used this feature to write a 'Gear' generator which can produce a very wide range of gear types and sizes for 3D print. The equally clever folk at the G13DCircle spotted this on Thingiverse and highlighted it to it's subscribers.

I haven't quite fathomed out the Customiser myself yet (I'm still a White Belt in SCAD terms) but I thought it was such a useful idea that I would publicise it here for others to take a look at. Gear types currently supported include:

A week or so back I was looking for a rear cover for a NEMA23 stepper motor. I found one on Thingiverse which had been revised to work with OpenSCAD and was parameter driven. I had heard of OpenSCAD but never used it. Simple download, loaded the Thingiverse file. Worked a dream to get the size cover I wanted with room for XLR connector for connection to stepper controller.

I've done this with several Thingiverse designs which were simple enough for me to understand (e.g. the variables that I needed to change) to get the end result I wanted. I don't think this 'portability' would be quite so easy with other 3D CAD programmes?

While looking for stuff on drawing bevel, helical and worm gears, I came across a new gear generator, posted by Rainer Hessmer three days ago. I tried it out, and thought that the following info might be helpful to others.

I have to say, that was a thorough and well written review, I enjoyed reading that. I clicked the post out of curiosity and was impressed by the length, but had no intention of reading it all; until I suddenly was at the end of the text. Thanks for taking the effort and for sharing with us.

Also, check out this interesting tool:

geargenerator.com Involute spur gear generator and simulatorGear Generator is a tool for creating involute spur gears and download them in SVG format. In addition it let you compose full gear layouts with connetcted gears to design multiple gears system with control of the input/output ratio and rotation...

To add to this. You can easily cut gears out of Delrin (acetal homopolymer). This makes gears that can also hold up to some additional stresses in applications that acrylics would not be suitable for.

Liz: As someone who didn't grow up outdoorsy, when I got into hiking and backpacking as a young adult, I realized having the right gear could help make up for lost time. After my first thru-hike of the Tahoe Rim Trail, I knew I had to lighten up if I wanted my feet to survive a thru-hike of my first long trail, the Appalachian Trail.

As I researched gear, I realized that many of the big gear review outlets weren't using tents, backpacking backpacks, or hiking shoes to the extreme amount of miles and conditions I wanted to take them. I started writing my own reviews as I went on to tackle the Triple Crown trails and a dozen other thru-hikes of varying lengths. It was fun to write and I liked helping other hikers, backpackers, and outdoor enthusiasts understand how gear holds up on the long haul, in desert heat and blizzard conditions, and for month after month of unrelenting use.

After years of blogging about my personal experiences with gear, I was "discovered" by an editor at Wirecutter, the New York Times product review site, who knew about me because of my fastest known time (FKT) on the Appalachian Trail in 2011. I was hired on as a staff writer to test and review gear. Several years later, when they closed the outdoor gear section, a dedicated team of fellow outdoor writers wanted to keep the same spirit of objective, obsessively researched outdoor gear reviews alive. So, we formed Treeline Review, where I have been editor-in-chief for the past four years.

To help outdoors people choose their one-and-only gear, we rigorously test a bunch of similar looking models. Many other outlets will test a backpack on a day hike. We'll take it on an 800-mile thru-hike. Many outlets will write a review of a single product. We rank gear items side-by-side to see how they stack up against each other.

Our reviews are live on the website at treelinereview.com. We also are active on Instagram and Facebook, as well as a YouTube channel for some of our more interesting gear findings, how to do repairs and maintenance, and fun things like how to build a home climbing wall.

In fact, I recently thru-hiked the Superior Hiking Trail. As I was sending work messages to colleagues from a mountaintop where I got reception, Naomi reminded me of our commitment to staying present in the outdoors and cut me off from doing work! I am so grateful that she did so I could focus on the restorative power of nature instead of content needs or gear news. Ultimately, I think our readers and followers value that when Treeline Review's team gets outdoors, we are doing it first and foremost because we love being in nature.

First, don't let anyone tell you or make you think you can't be a gear reviewer. If you're getting out and thinking critically about what you are using, then you have the right mindset to review gear.

My other advice is to try as many different types of gear as you can. Seemingly similar models from different brands often have small differences. The more gear you not just see, but use, the more you can get a taste for how subtle design choices impact your day-to-day experiences.

Testing gear is about learning how gear works in the field. The best gear will not just serve you in the best of times, but in the worst of times. A quick release cord may be nifty on a sunny day, but it could make a huge difference when your hands are too frozen to fully operate. A buckle may not make a difference on summer days, but can prevent snow or leaves in the fall from accumulating in your pocket. The more experience you have outdoors in different seasons and different locations, the more you can appreciate how small technical features on gear can make your trip feel easier, more efficient, and more enjoyable.

This is a minimalistic gear design application. As such, its designs are made following the metric module DIN standard series. Regardless, it is made for everyone, no matter your amount of knowledge or if you have an engineering background. It includes 11 different types of gears (7 standards, 2 non-standard and 2 experimental) for every project you might want to implement them in:

The two types considered non-standard were included for 3D printing since these designs of internal gears have proven to be practical when tight tolerances are a liability. Nonetheless, these designs are as useful as others.

Hi, this IS NOT an error inherent to Mac OS (Ican tell since I have a Mac M2 myself and I've made tests with it, as well asthe autodesk team on a Mac M3). What seems to be going on is that you have Capture Design History mode disabled, thus not allowing the app to work properly as it uses the timeline to hide bodies when creating new gears (to avoid interference and unwanted modifications to other bodies). Please enable the Capture Design History mode and update us.If you're still having issues, I'd be glad to personally walk you through them, just send an email over to gfsolucione...@gmail.com .
