Slider joint direction

[maik_staudt]

Hi,

I tried to put a linear bearing onto a linear guide rail using the silder-joint-command.

The problem is, that I don't know how to change the sliding-direction of the bearing. In Fusion 360 it works perfectly, but in Inventor I don't know how to do it. 

Here you can find a video of the problem:

Thanks,

Excuse me if I do not interpret it correctly.

Could you use constrain -> mate -> and then select central bearing axis and then central axis of linear guide?
I hope you can solve your problem

Hi! I see the confusion now. Actually, Slider Joint is not going to create the desirable movement in your case. You need to use Cylindrical Joint instead. Slider Joint is for two planar faces and one component moves in one direction along the face.

Many thanks!

Thanks for your quick replies. I was confused because it works with a slider-joint in Fusion 360 which doesn't seem to work in inventor.

The bearing only has to move along the rail, and there should be no rotation of the bearing. So I used a cylindrical joint and tried to set the angle to zero to avoid the rotation around the axis.

But the bearing still rotates around the rail. Is there a possibility to avoid the rotation of the bearing ?

Thanks a lot,

Maik

Attach your Inventor assembly here.

It might also be helpful if you File >Export and then Attach your *.f3d example too.

Is this what you try to do?
Greetings.
I hope you can solve your problem.

You could use the top of the bearing block and the bottom of the rail, use the needed gap to raise the bearing to the rail, and then use you use your alignment options to orient the bearing. Then the slider will work.

Use the "Slider Joint" and use the align tool to change the sliding direction.

I am struggling on the same issue. I want to create a Slider joint between 2 circular parts. This is to simulate a hydraulic cylinder. Can someone help on this one Please?

Thanks

Please see Johnson's response above, you need a cylindrical joint not slider.

Hi James,

If I use Cylindrical Joint,  cylinder rotates along it's axis. However, I want it to move IN and out with no rotation.

I tried using cylindrical joint & then adding angle constraint to one of the cylinder plane. No luck with it.

Thanks.

Depending on how it's modelled you may have to create an additional plane to stop the rotation. Usually there is a flat on the rod and a flat somewhere on the cylinder body that can be used with the angle constraint as you say. 

If you're still struggling please upload the files and I'll do it for you.

Can you not just use the insert constrain with locked rotation and set its limits?
