Hello,
I am new to Gearotic, and am trying to make a set of oval gears. When I create them as second order non-circular gears, i am shown the major axis radius dimension . However, I want to control both the major and minor axis dimension s so i can fit the gear size to my particula r applicati on. How can I change these dimension s? I feel like there should be a center/center dimension that i can control, but I can't seem to find it.

Also, does anyone have any good hints for importing gears into solidwork s using .dxf or .stl files?

Thanks,
Jesse

Hi Jesse:

    The actual center to center dimension s are a function of the Module or DP
of the gear.
  You can however get exactly what you need if you consider the numbers
are ratios.
   There is a bug in the pinion radius display, fixed but not published as yet,
so measure the pinion radius if its important, or just use center to center distance display. Adjust eccentric ity for the ratio between major and minor
axis on the wheel, then use module or DP to adjust the center distance,
the end dimension s should then be correct to your spec.

  Module or DP are linear in effect, and will affect all dimension s.

Thanks Art.
Is there a place where it shows the ratio of the Major/Minor axis? I've heard this called the "K" value before, but didn't see it anywhere.
