tooth profile of a gear

[chiodoarrugginito]

hi, as from object I had the need to draw the tooth profile of a gear (evolving) to draw a gear in a complete way. I would like to know a simple method to draw it with solidworks (I don't have the tool though).
:finger: thank you.

Hi.
You could download a wheel dented by traceparts and get the tooth sketch to reuse on another model.
or use the various software that you can find shareware in the internet (mitcalc for example).

thanks to the answer, I think it is the fastest method because I remember that tracking it as you once did is a long process. Would you just give me a little more detailed indication of how to download from traceparts?

Thank you. I hope it's really free!

the simple method is to draw a spline or curve between three points defined as basic, primitive and head value. graphically looks a lot like the evolved and it really takes 4 clicks and 3 accounts from manual.

A similar case happened to my partner, but he needed the exact profile because he had to draw a mold and then print the injection gear. if I don't remember bad he used a free two-dimensional software that tracks the profile in dxf.

depends on what you need.. if only for "visualization" or for a real constructive need (it happened to make "grosse" dentatures of cn one tantum..). because those profiles (as well as toolboxes) are not real but simple arches; In that way it is also simple to model them alone (when you know the module and then addendum and dedendum). If you need a precise study of real enragment you are obliged to pass through the construction of the evolved.

Thank you. I hope it's really free!

yes is free (some, few, parts/producers are paid).. What doubt do you have? Didn't you give the credit card to the registration? :biggrin:

greetings

@sampom: it was precisely the construction of the evolved that I wanted to avoid, the method I used was student level and the tracking was very complex. even if free you never know... the virtual world is becoming increasingly cloudy:smile:

@meccanicamg: thanks is more or less the road I have taken along with the classic calculations:finger:

@cacciatorino: Fortunately it is not my case because designing a gear can seem simple but it is not (involving precision gears).

thanks for your attention, piero :biggrin::finger:
