Drawing a Straight Gear with Solidworks

3D Design Volume Model

Hello

 

Is there a function to draw the true profile (circle involute) of a gear?

Hello, can you expand on your question?

 

Thank you

Hello

 

All the information is in the link below. The subject has already been discussed.

Hello

Yes, you have to draw a tooth using the circle involute as @s.b says, and then make a repetition of this tooth around the edge of the pinion.

A supplier asks me for the dxf of a gear to carry out the machining

and the file I have was drawn succinctly at the time (not the real profile of the teeth)

Hello

 

There is no function as such, but in general it is a repetition of a sketched tooth:

It's possible with the Toolbox but a priori the representation is only approximate.

Hello

There is no direct feature in SolidWorks.

You can go through the equations either:

- directly by the "Curve driven by an equation" function (by retrieving the information in the subject already dealt with and reported by s.b)

- by the "Curve passing through XYZ points" function for which you can point to a file generated by formulas from Excel.

Once your circle development is created, you can actually use the repetition to get your gear.

Kind regards

Well your question is not very clear but to make a gear you can draw a single tooth the extruded and make a circular repetition of your function. and you'll have your gear. then if it's not what you're asking specify your question Kind regards Bastien

I'm a bit late (normal RTT today !!!), but there are SolidWorks library functions including the gear:

He doesn't make your supplier do anything.

 

To machine a gear, there are special cutters for it, with different numbers depending on the module and the number of teeth.

 

I would advise you more to go to a supplier who knows how to cut gears.
