Even though the universal joints mechanism seems simple the physics behind this mechanism are rather complicated and interesting. The universal Joint has three basic parts, two yolks and a cross. Now let's consider different power transmitting scenarios In the first case the input and output shaft are connected in a straight line in this case motion is really simple.

Assume that the input shaft is moving at a constant speed Here the motion is quite different to understand why just note the behavior of the red and green ends of the cross. You can see that the green ends which are connected to the input shaft turn along a vertical plane While the red ends which are connected to the output shaft have to move along a different plane.

The reverse Spin will have an opposite effect on the output shaft rotation. Just by taking a simple time differential of this displacement graph we can find out speed of the output shaft. It is clear that the output shaft is a fluctuating speed as shown.

I'll just go ahead and do that so you enter your details company name category, now the conveyors are grouped by this category. So if you have a project you can group all the conveyors in that project in this one category, so in this case I'll just call it mine site A and you can enter some more project information.

It's gonna create this conveyor in that category so if you get stuck just go to your categories and then we can open the conveyor from here. I'll just introduce you on these pages quickly. From this page you can list all your conveyors in this category and you can open them or you can just view the project details, so I can just edit them quickly without having to open the whole conveyor you can save from here.

I selected here I've just made a copy of this one, so now I can open them both in two different tabs I'm just middle clicking with my mouse wheel here and I've opened both of these conveyors in two different tabs and what I can do is I can change the belt on one of them for example and calculate and then save save that one and then I've got two different versions of the same conveyor.
