do you mean helical gear? you have 2 choose:
1- using geartrax software
2- using solidworks tool box
design library> tool box> Ansi metric> power transmission> gears> helical gear
left double click on "ANSI Metric (outline item)" in "SolidWorks Premium 2012 x64 Edition
left double click on "Power Transmission (outline item)" in "SolidWorks Premium 2012 x64 Edition
left double click on "Gears (list item)" in "SolidWorks Premium 2012 x64 Edition
right click on "Helical Gear (list item)" in "SolidWorks Premium 2012 x64 Edition
left click on "Context (popup menu)"
he mentioned in question... NOT HELICAL.
if you look at the images, they are helical!
Thanks gill, please correct me if I'm wrong...
Thanks Ali but the toolbox is not installed with my software in Library Design tree, what should i do to install it?
even than toolbox is not capable of helical gear left handed... :(
put a check mark in "solidworks toolbox browser" in start up
Do you really mean Helical gear(which is studied in mechanical engineering design) or diagonal gear ?
seems to be a bug!!!...
well i'm sure geartrax can produce left handed helical gears...
The way I would do it is:
Start a sketch on a plane somewhere above the middle of the part.
Draw a line and dimension it at an angle from a "centerline" set to be vertical.
Extrude the line thin feature, NOT merge result.
Chamfer it a few times to make it look right.
Then circular pattern the body and combine all the bodies at the end.
Thanks for your guide but could you please send me your modeling way with a simple SolidWorks example? I can't do that and it's a little amazing for me.
