I like your method for the initial alignment of the gear pairs. However, when setting the mechanical gear constraint, another method is to select the pitch circle diameters of both gears. Solidworks will calculate the gear ratio based on the sizes of the 2 pitch circles. If you later change the ratio of the gears, then the gear constraint will automatically update. This method of setting the gear constraint is also very useful when using timing belt pulleys.

Thanks mate, it was a frustrating way until i found this video. I owe you one. ♥

professor yang, really appreciate you.

I like to use physical dynamics to check if the gears turn properly, seems a little more satisfying than using mechanical mates.

This was incredibly helpful for my project. Thank you very much!

super video it is very helpful

Hi there, do you know why solidworks spur gears only allow certain diametial pitch values, is it due too gear wear, or gearing issues?

Another great video, thank you.

thanks a lot

nice lesson, thank you

I have a problem, when I increase the number of teeth my dedendum circle diameter gets bigger than the base circle diameter but this should be the other way round...Can you help me please? Thanks in advance

You speak good English mate, proud of you as a Chinese!!

Totally perfect. Thank you !

that was smooth

Hi, I have a problem with this. Both of my gears are having the same diametral pitch but when I am arranging the gears, it seems the teeth would interfere with each other. Can anyone enlighten me on this?

Hi, Wonderful tutorial. Could you clarify why the front planes have to be made coincident when you have already made the front surface of the gear and pinion coincident?

Hello Mr.Yang Cao..can you show me how to do BEVEL GEAR assembly? Thanks

Why dont you use gears from toolbox components?

where can i find your earlier tutorials? thanks

As we have applied 5 rpm to the driver, please tell where can we find the rpm of driven gear through software?

Why can't I select the centerline?

Great video, thanks! Question: how come a gear can't have fewer than 13 teeth? I've googled my ass off about this and came up with nothing.

thank u

mate PD circles to tangent

At 10:38 you hit green checkmark but you only had one line selected. That's why the two lines were not actually conicident when you tried moving the gear. I really hate it when someone claim to be an expert in SolidWorks and post videos for the public. Yet they make silly mistakes that waste the person's watching time !
