    Helical Gear Form Questions

    Has anyone heard of or seen the phenomena where the base circle diameter of an involute helical gear is larger than the root diameter??? I am running into this an can't determine if it is a problem or not. See attached screenshot of the beginning of a model for a helical gear in PRO-E. Shown...

    Fixing IGES File surface data

    many know that other customers and vendors use different CAD software. and we know that we can import there files into our software programs. for example IGES or STEP files. to do this we import the file into a new part model. once we do this we will see only one feature in the model tree, an...

    My ProE run so slow!

    From personal experience of slow running pro-e, framing screen, slow loading, etc. etc.. It was because my computer didn't have a fast enough processor or insufficient memory. After working with Pro-E for a year with this same computer, my employer purchased me a brand new Dell, since then...

    Wire sizing

    so far I have come up with these gage wires for these lengths: 0' to 5' = #8 5' to 8' = #6 8' to 12' = #4 12' to 16' = #2 16' to 20' = #2 20' to 25' = #1 Now this is for copper positive lead wire for a 24 vdc starter motor, 140 amp draw, and a voltage drop of less than .500 volts over these...

    Wire sizing

    No, this is not a college homework problem. I work for a fire truck pump company, we have a 12 vdc and 24 vdc version starter motor, which incorporate a solenoid. These motors are engaged by pulling a valve handle to the open position which connects the circuit to ground, engaging the motor...

    Wire sizing

    I have a 24 vdc motor, that will be running at 140 amps. I need less than 1/2 volt of voltage drop over the length of the wire. I have lengths of copper wire for the positive lead as follows: 0' to 5'; 5' to 8'; 8' to 12'; 12' to 16'; 16' to 20'; and 20' to 25'. What is the best way to...
