Assembly a roller that rotates and slide along profile in the same time.

gog_andrey

Hello,
I can not manage to assemble the roller to do two operation at the same time,
also the slide mate is hard to put because of round shape of the object.

Any ideas?

Try pin slot mate - made exactly for this situation. You may have to edit the mate connectors to get it rolling the right way.

@gog_andrey, You can use "Rack and pinion" relation for this case. It relate a mate with a rotational degree of freedom to a mate with a linear degree of freedom. Please refer below steps to add the Rack and Pinion relation:

1. Click .

   

2. In the dialog, confirm that Rack and pinion is selected.
3. Select two mates in the main list of mate features (or in the list of features in any of the current subassemblies). Note that selecting a Slider mate and a Revolute mate provides the exact degrees of freedom required by Rack and pinion.
4. Specify a degree of freedom for that mate, if necessary:
   1. When you select a Slider mate and a Revolute mate, no further action is needed because each has the exact degree of freedom required by Rack and pinion.
   2. If you select mates with more degrees of freedom than required, a second dialog appears in which to select the desired degree of freedom for that mate.
5. Enter the desired linear value.
6. Optionally check the box to reverse the direction.

Note:- Once you select a degree of freedom for the relation, you cannot change it unless you delete the mate from the dialog, change the mate type, or delete the mate and start over. Please refer below  example video of using the Rack and Pinion relation for assembling an arbor press.
