Here are some pics of what I'm asking about.

Engineers, I've been thinking about starting a sort of modular furniture business and came across this shelving unit in the alley that is almost the exact construction method I want to aim for. I could certainly measure everything up and make the changes I want, and send it off to local machine...

I found the error in my math. Should've divided 500 rpm by 60 first before getting angular velocity. Can't thank you enough for helping me answer this.

Wow that was a great explanation. Thank you for helping me understand. I calculated about 5HP needed to overcome the losses. For acceleration up to 500 RPM in about 10 seconds: 500 RPM *2 pi/10 seconds = 314 rad/sec^2 (fairly slow acceleration) Solidworks tells me all that mass has a moment...

I forgot to mention acceleration should be relatively slow so as to not spike the torque by any substantial amount.

Brian, Finally someone gets it! Haha yes it's a Four-square. Not many people I've come across have heard of that. I estimated a 30% combined loss from all of the gear boxes. I was planning on having an inline torque sensor from Magtrol monitor the torque. The motor would have a variable speed...

Hey all, I'm having trouble selecting a motor/gearbox combination to help me with a torque-testing machine I am trying to make. The motor distributor is recommending a motor that I think might be too big. What I want to do is apply a torque up to 2500 in lbs to a servo coupling, and turn it up...

Hi all, I've been a lurker here for maybe 10 years. Run into an application that I'm struggling to even begin, and I think some of you have the expertise to point me in the right direction. I have a client who is looking to test a a line of prototype mechanical servo couplings. They want to see...

thanks for the replies, using a stabilizer would work but this is a fully integrated computer/camera vision system by allen bradley. The camera is basically a cylinder about 1" in diameter, and this feeds directly to the computer which compares parts it sees against a trained "normal." I'm...

Hi all, Background: I have a vision system mounted to a piece of automation with a precision link conveyer. Right now the vibration from the feeder bowls are causing some problems for the camera. I'd like to mount the camera with a custom bracket to the base of the machine, rather than to the...

Hi all, I recently purchased a GE Fanuc series 90 micro plc model# IC693UDR001NP1 off of ebay to try and learn the ins and outs of plcs. The seller included logicmaster and versapro, but the firmware was only 3.01 -not current enough to run versapro. I read that logicmaster was virtually...
