    lasr closed drawing stays in window

    Whether 1 or several drawings, both part, assembly and idw are open, the last "file" that I close from my session stays on the screen. Kind of like a "wallpaper". I can go to the icons and open other drawings and move forward. Just not sure whty the last drawing stays on the screen? IV 2009...

    How to make v-guided belt follow path?

    You can also drive certain functions, such as length, from a spreadsheet. Thus, the model would update to the new length. Every once in a while the voices in my head have good ideas.

    sprocket vs gear box

    You may want to consider if the "load" is going over center, a system that will not allow the dumper to speed up. I'd prefer hydraulics over anything that has a chain. I can put a fuselink in the system to eliminate a run-away synerio. Just my opinion. Ray Every once in a while the voices...

    Solution for conveying starch to a height of 6m

    I would look at the screw conveyor with a coated auger and sides. I beleive that anytime you have to lift something "overhead" there are always chances for accidents. Of minimal value, but wouldn't the heat and humidity be higher at the "top" of the hopper. Storing 3 days supply on the...

    BEST MATERIAL SPEC FOR ROLLERS

    Thanks to all for the help. Our vendor was able to balance the pulley. I believe the "dificulty" was in the DOM tubing to begin with, as I tried a method of checking how true the material was, as posted by MFGENGGEAR, and I was pleased/unpleased to find out that it was out about .010" And at...

    BEST MATERIAL SPEC FOR ROLLERS

    The "hubs" / journal ends are seperate from the main body of the pulley and the "initial" balancing of the pulley. The assembly will be balanced as a unit after the body is balanced, as the body consists of ~95% of the mass. The journals are a bolt on part, with the (4) bolt holes being equally...

    BEST MATERIAL SPEC FOR ROLLERS

    I have an application where we are using 3-1/2" DOM steel tube to create rollers for a web handling machine. THe issue is we are "attempting" to have the roller dynamically balanced and are having issues. The RPMs are up to 3100 RPM, and in our clculations we go through 2 critical speeds. The...

    Inventor - AutoCAD drawing query

    I have a similar problem. Does the method mcgvr present allow the "components" to be more than just individual lines in the AutoCad drawing? We manufacture web handling equipment and when the customer wants a Autocad drawing it gets messy. Our machines have 4,000 to 7,000 parts. Thanks Ray...

    CROWNED PULLEY

    I have an application for a unwinder for the web industry. The conveyor belt (20") wide engages the mill/parent roll of material (40" od) to unwind the product. I need to unwind at 2000 feet per minute and I have hesitations about the "proper" crown for the pulley for tracking. The conveyor...

    2000 fpm CONVEYOR

    The duty cycle is up to 8 times per minute to go from 500 FPM to 2000 FPM. We run at the high speed (2000 FPM) from anywhere between 1/2 second up to 22 seconds, depending on finish roll length. Also, to answer DVD, I was scheduled to go to Oklahoma for the seminar, but this project trumped my...

    2000 fpm CONVEYOR

    I work for a web converting company and we need to unwind "mill rolls" at 2000 feet per minute. There are 2 primary methods to "drive" the roll (55" wide x 40" dia x 2800 #s) either core/chuck driving and belt driving. The core/check is equating to about 100 HP as we need to go from 500 fpm to...

    DISAPPEARING TEXT, NOT SAME OLD ISSUE

    We've just loaded a new computer with Inventor 10 and the text does not appear in drawing files. Same as in older threads. Tried the Microsoft update removal that the old thread refernced. Can NOT remove that update. Tried the fix through AUTODESK, could not run them. Went back to AUTODESK's...
