Detailed gear parts affecting Onshape speed?
I've imported some gear shapes into Onshape Part Studios and now my assembly is sluggish when I attempt to starting mating components together. I used a program called Gearotic to specify the gear features (DP, # of teeth, and PA), exported that to a 2D DXF, imported the DXF into GeoMagic, to extrude the basic gear shape,… -
Re: Detailed gear parts affecting Onshape speed?
@Michael3424 I suspect the problem lies in the approximation of the involute curve on the gear tooth flanks. I used to generate 2D geometry in AutoCAD back in the day and then import it into SolidWorks and extrude to get a gear in 3D. I would get a similar slow down in SolidWorks on large gears (lots of teeth) with a… -
Re: Detailed gear parts affecting Onshape speed?
In most cases a true involute gear profile is not necessary, just as in most cases a detailed helical thread is not necessary in a model. However, there are those times when you not only need these features, but they must be dead-on. SolidWorks has an involute function and I saw a demo of how to use it to make a gear… -
Re: Detailed gear parts affecting Onshape speed?
@Michael3424 I wasn't thinking of Onshape doing it, but a specialty company using the Onshape API to generate gears based on design layouts and calculations. -
Re: Detailed gear parts affecting Onshape speed?
I generated my gears from scratch in OnShape. Actually quite quick once you know the steps and results in 3 faces per tooth (5 including the fillets). which is quite manageable for me in terms of speed to mate etc. I used this tutorial with the exception of the equations. Worked well you can see my resultant model here.…
