On previous occasions I have had difficulties when designing gears manually, using GEARTRAX has been easier and with an easy interface so I highly recommend them, you only need the data of the gear (perimeter diameter, number of teeth, width, external diameter , angle of teeth, etc,) and geartrax is linked to solidworks to design it automatically. if you do not have a license and want gears just tell me and send the technical information to help them
that is the free version is 10 days of test with your serial of SOLIDWORKS, I have the PRO version but it is cracked, but I do not know if I can publish it here in GRABCAD, or if it violates the rules of the community, let me investigate if possible, and I upload to a server to be able to publish it if possible.
Several days ago I had commented to them the possibility of sharing this software with you (GEARTRAX), as I told you I did a little research, and I contacted a GRABCAD staff member, and I confirmed the policy of not publishing or share here in GRABCAD cracked or pirated software.
This software is made by Camnetics and they make a complete suite which has Camtrax,Gearteq and Geartrax if you make gears ,pinions,cams etc etc its really worth having just open which one you want to use and fill the fields with all the info ie diameter,width,how many teeth and alot more then click make cad files and it will automatically open Solidworks and make your part or assembly its amazing to watch how quick it makes the sketches and extrudes,lofte etc and all perfect as in ready to be made,if its something you would use regular its not that much money for the time saved.
First, geartrax is more of an external complement to solidworks, so you need to have it in the current version you have of solidworks, for example I have SW2020 and Geartrax 2020 for SW, if you try with another version other than the one you have it will not work,
Second, you only need to open geartrax, enter the type of gear and data to create it and select the CAD option, so that it can be modeled in SW either just a part or assembly, and it automatically opens SW and generates your part.
