Modeling a ball screw using Solidworks ?

[Chaabain]

Hello,

I would like to know how I can model a ball screw using Solidworks. I know it's slightly difficult to explain that in such a way but I really need to know how to do that even if you can guide me by telling when I can find the good book for doing that, :cry: .

Thank you in advance,
Chaabain

What release of SolidWorks are you using? Can you zip and attach what you have so far?

I'm using Solidworks Office 2007.

As you can see in the attached figure, as the lead screw rotates, the load translates in the axial direction of the screw.

That's what I need to model using Solidworks.

Thank you in advance,

I know what a ball screw is. That doesn't look like a ball screw - it looks like an ACME thread. I was expecting that you attach the *.sldprt as you have so far so that there is absolutely no confusion over your actual design intent. Zip and attach what you have so far.

Actually, I didn't draw or model that using Solidworks because I don't know how I can do that and that's why I have asked how to do. I have no *.sldprt to attach because I didn't model it till now. Could anybody help me to draw or model this mechanism (Whatever its name) using Solidworks.

Thank you very much for your help,
Shaban

Have you taken a class? Are you asking someone to do your homework for you? Do you have any specifications for this screw?
Pitch, diameter, length, ...

It would help if you give it a start and attach what you can do. What is the profile? Hemispherical or 29° ACME?

I have to agree with JD on this one.
Lucky for you, you have is an easy model.

Go to the library and look for "Machinist Handbook" and it will have a really detailed explanation of a ball screw as well as all the standard parameters a ball screw may possess. Once you see the schematics you will have a much better understanding of which are the most important measurements and how to create your model. Hope this helps you, as I know it has helped my colleagues with other hardware components.
