    How to Lock a Shaft at Infinitesimal Increments

    Thank you CWB1. I was actually able to do this with a gear motor. The torque required to backdrive the gear motor exceeded the torque requirement. However one of the other requirements for this project is that I cannot use any motors or electronics. Thank you.

    How to Lock a Shaft at Infinitesimal Increments

    Thank you Everybody for your suggestions. I believe that JohnRBaker's reply may be the best path. I just have to work out the kinks. And yes BrianE22, this probably has to be a friction device in order to achieve the "infintesimal" requirement. I also need to maintain the specified holding...

    How to Lock a Shaft at Infinitesimal Increments

    Hello Forum, I am trying to prevent shaft from rotating in BOTH CW and CCW directions when the shaft is subjected to about 2.5 N-m of torque (about 22 in-lbs). The default state of the shaft should be "locked". Then with the push of a button, I want to release the locking mechanism, allow the...

    Using SolidWorks Flow Simulation to Determine Which Fan Blade is Better

    Hey Everybody, I am using SolidWorks Flow Simulation to look at the internal flow of air passing through a tube. Inside the tube is a small fan blade (approximate .700" OD). I am simulating the fan blade running at 2000 RPM. I have several versions of the fan blade, and I am trying to figure...
