Guys I want to create an assembly in which the rack remains stationary and the gear moves back and forth but I do not know how to assemble this using iso metric assembly..as for engineering reference tool it creates a default assembly in which the rack moves...if anyone could tell me asolution I would be glad..

also I am new to Solid Edge...and Parts assembling so if you could give a video or a  tutorial it would be handySmiley HappyHeart

Re: Enginering Reference

if al is working as you desire just the inverted part...

 

I'd suggest underconstraining the pinion and then grounding or otherwise constraining the rack.

 

this should work for you.

 

 

or from scratch:

 

drag into your assy the rack, which should ground.

place pinion and apply gear relation rotation to linear.

apply a motor to the gear relation if you desire.

 

pretty stratightforward.

 

look at SE Help for "gear" if need be.

Dear sir
I tried applying gear relation as you said; but the gear i.e.pinion is not
moving back and forth; instead it is spinning in the same place.
I want it rotate and move at the same time along the rack....
Pls help me in this issue

Re: Enginering Reference

heres a quick video that should get you going.

let us know if you get it working or still have issues.

 

HTH!

I did this some time ago so it may well not be the best way to do this but you can put a shaft through the pinion with a transverse hole and drive the shaft with a linear motor along the axis of the hole.  You can also drive the pinion with a rotational motor.

Below is a link to a new animation of an assembly I did some time ago. unfortunately although I created this from reference manager I removed the gear relations and did some calculations to estimate the rotation/linear movement ratios.  This is not ideal and using the gear relation as Matt described would be better if you can get that to work.

Thnx 4 ur video dear Matt,

I think I found my problem....

Hope You could solve this...

I reviewed my work step by step and when I tried to edit the definition of my motor it worked with "no analysis" option selected. So tried with another option "Detect collisions", this time too, to my luck it worked... but alas when I set back option to Physical Motion it stopped working.

I think this is my problem in this assembly... Pls help me... BTW I had attached the video link in which the assembly works as intended.(with 'no analysis' option selected)

Karon,

 

Unfortunately, gear relationships are not supported using the Physical Motion option.
