Hi Vipin kumar,
You can do this model in solidface, take a look at this link and i think it will help you.
I am sorry, but the tutorial does not show that on the video. The only video on making gears is this one: https://www.youtube.com/watch?v=RIaQ8GNzcFw
so very diferent from a helical gear. I mean, making a gear train would be an absolute knightmare because one cant trail gear sizes, but instead design every sigle one of them.
SW has reached very far for having extensive tutorials. I encourage you to do the same. Also, there are no actual tutorials on the mechanism designer
have a good weekend, please sleep on this suggestions
