Gear from toolbox question

[Azum]

This seems a bit strange and maybe its more a gear question than toolbox but I am checking if anyone has any insight into this before I look stupid by putting a fault line into Solidworks.

I have been looking at a DIN helical gear MOD 2 40 teeth
PCD of the model is about 113.5 which is for crossed shafts ie Shafts at 90 degrees Parallel shafts should be PCD of 84

When I look at a ANSI Imperial DP10 21 teeth it comes out at 2.205 PCD which is parallel shaft and i cannot get crossed shaft which should be 2.970 inches.

I cannot see any button to cahnge from cross to parallel shaft model so wonder if I am missing something or SW have got thier models mixed

Cheers for any viewpoints

Azum,
How much gear design do you do? There's a 3rd party software called GearTrax. Are you familar with it? I used it at my old company and it works really good.

Here's a link:

Hi Colin
I do not do much original gear design at all although I do a lot of cam design so your link is very interesting

I was really trying to get the model to come in at the correct PCD so that my assembly model looks right

We are buying the 10DP 21 to 42 teeth pair from the catologue so I know what the PCD will be. It just looks odd in the assembly when the gears do not touch and I wondered if there was some way to bring them in as crossed pair like the DIN gear does.

Or for that matter bring the DIN pair in on parallel shafts should I need to in the future

Azum,
As you can see the link has a page for Camtrax software. I nevered used it, but if it works like the Geartrax software it has to be awesome. It's very low cost software, but has a big bang for the buck. You might want to call and chat with the owner. I think he's a one man show, but is a very nice gentleman. Make sure the software work with the correct version of Solidworks you're using.

Best,
