    SO CONFUSED ABOUT SPUR GEAR MATCHING.

    The attached picture shows how I used to do this - in this case 13 Teeth, Module 10.0. I imported the data into AutoCAD and then connected the tangent points on the outline to get an accurate representation of the profile. I was never able to find any vendor drawings accurate enough. Seems like...

    Gear Pinion outside diameter calculation

    Several years ago I wrote a program to calculate all these values, but you could try to get a catalog from Quality Transmission Components "Handbook of Metric Gears" that includes calculation formulas. However, if you stick with a 15deg. helix angle, the values should be 20 teeth -> 91.1, 22...

    Gear Pinion outside diameter calculation

    You should really know the helix angle of the gears, otherwise it is just guessing - e.g. with a 15deg helix angle your existing gears should be 111.8 and 173.9mm respectively.

    ellipse gear

    If it's not an elliptical gear - the low a/b ratio seems to indicate that - then there should be a center mounting hole with a dowel hole next to it in the direction of the longer axis to line the pre-machined outer contour with the EDM code und the part can be clamped through the center hole.

    ellipse gear

    Me? Not even close. But why don't you just wire EDM it or don't you have the contour of the finished gear?

    Thread information spreadsheet

    Hi, Maybe this will help you - some translation necessary, but it should all be pretty obvious.https://files.engineering.com/getfile.aspx?folder=0c158c05-3d6d-42c2-ade1-6207e47d8c35&file=Gewinde.xls

    MathCAD not solving equations when there are untis

    Hi, Little bit old, but it still might apply.https://files.engineering.com/getfile.aspx?folder=c4d31d20-65a4-40c4-b415-7303a88a9cd1&file=Solve_Block.pdf

    Spline CAD for shafts DIN 5480 f8

    Here is a drawing file. If you also need *.dxf let me know.https://files.engineering.com/getfile.aspx?folder=8b6dadf9-160e-497f-9614-87a688706a22&file=W140x5x26x8f.dwg

    Design data for Spline based on DIN5480

    I don't think it's supposed to be "tot" but rather "to" meaning the addendum change is allowed to vary between these two factors.

    Design data for Spline based on DIN5480

    This is not the actual standard, but maybe enough to get you going.https://files.engineering.com/getfile.aspx?folder=ee1b665a-6660-444d-8815-ea10a23e4056&file=DIN_5480.pdf

    autocad dimensioning

    I don't know about 2002 (don't remember), but in 2014 you go to "dimstyle" - "override" - "alternate units" and use for "multiplier" 0.08333 and "prefix" "-" (without quotation marks). You can also adjust the decimals as needed.

    thread modeling

    I agree. If you don't align the profile, let's say with the X-axis, and use the "Sweep" command, it will always stay perpendicular to the generating path.

    Motor Datasheet Confusion

    Hi, From what I can see, the peak torque in either case (12V or 24V) is approx. 4000 g-cm

    Polyline

    If your intent is to connect all the point in your sketch with a polyline using a script file then, what I generally do is read in a text file with all the points and then connect them using script. However, the two radii you have shown would then have to be created using the "Arc" command...

    FLENDER DMGH 25.4 carb bearing failure

    Maybe you can find a spare in the attached - although they only list spare part numbers.http://files.engineering.com/getfile.aspx?folder=18405532-e764-4115-b007-ed03bbb6e6cb&file=DMGH.pdf

    are "lantern" sprockets necessary

    If your requirement is absolute linear motion, that's what you need. Otherwise - no.

    What is a "phase angle" in a mechanical drawing?

    At this point I think, it is just a chamfer at the entrance of the hole that you insert that sensor into to prevent the O-ring to be sheared off as you insert it.

    What is a "phase angle" in a mechanical drawing?

    No, it is just a chamfer and it should have been "Fase". If it was a tapered hole, it would have said "Kegel" somewhere.

    Question about AGMA standard

    I think, you read that wrong. Since it is a capital "P", it means diametral pitch and not circular pitch.

    E.g. see the attached - the second part is only to show it is the correct solution.http://files.engineering.com/getfile.aspx?folder=f3646cdd-543e-4076-8861-5238d19459db&file=Eng_Forum.pdf
