How to create a gear in SolidWorks?

Is it correct, if we select the desired gear from solidworks library, select sketch on one of its faces, then convent entities and then copy the sketch to a new part and extrude it??? I've done that made times but i don't know if its correct...

And does anybody know how could i create a bevel gear???

why you don't just modify that gear instead of copying its sketch and creating another part. you can have a set of parameters configured in excel sheet which will save your time.

You can take bevel gears from this location:
Bevel Gears (24T - 16T, M=3, Ratio 1:1.5)
and change parameters to suit.
