Practice exercise

00:01

This is a practice exercise video solution

00:06

for this practice. We'll begin with the supply data set gear assembly dot F 3D.

00:10

This design contains a base plate and a single spur gear that was designed in place.

00:15

We're gonna be creating an assembly with joints

00:18

and mechanical links between them using a motion link

00:21

to get started. We want to copy and paste the gear multiple times to do this.

00:25

We're going to right click on the gear

00:27

select copy or use the shortcut key control and see.

00:31

Then at the top level, we can right click and select paste

00:35

hit, enter to paste the new location

00:37

and we'll right click and repeat this one more time.

00:41

Now we have three years in the design. However, they're all in the same location.

00:45

We're going to select both of the two new gears,

00:47

select to move copy and simply move them out of the way

00:51

and capture their position.

00:53

We'll select the last one, select, move copy

00:56

and move it as well.

00:58

While this could have been done during the paced operation,

01:01

sometimes you can move things after the fact if they overlap, if needed,

01:05

notice that we do have a capture position inside

01:08

of our timeline for each of those gears.

01:11

Now that we have the gears roughly placed,

01:13

we're going to begin by going to assemble and selecting an as built joint.

01:18

The

01:18

ast joint type revolution can be used on the

01:21

first gear because it was designed in place.

01:24

We'll select the gear and the base plate and then the center

01:26

position of the gear to allow it to rotate and say,

01:29

OK,

01:30

because the other two gears are not in the correct place.

01:33

We need to use a joint which allows us to select the mechanical motion in this case,

01:37

revolution

01:38

as well as the origin or snap point.

01:41

So we're gonna select the motion type of revolution.

01:45

And for the position, our first gear, we're gonna select the bottom center.

01:50

And for the second position, we'll select the top center of the hole on the plate

01:53

and say, OK,

01:56

we're going to repeat this process using our

01:57

right click marking menu to repeat the joint

02:00

once again, making sure the motion is revolution

02:03

this time. Instead of rotating the gear around,

02:06

we're gonna hover over the center board and hold down the control key,

02:09

which will lock,

02:09

focus on this inside surface allowing us to select the bottom position on the gear.

02:14

Then we want to select the position on the plate,

02:17

make sure that the gear is in the correct position

02:19

and say, OK,

02:21

next, we need to rotate the gear. So they don't overlap.

02:24

We're gonna rotate the center gear first,

02:27

making sure that it doesn't overlap with the gear on the left.

02:32

Next, we want to rotate the right gear

02:34

and make sure that it doesn't overlap either.

02:37

Once they're in the correct position,

02:38

we'll select capture position and double click the mouse wheel to fit the screen.

02:43

Now, we can go to assemble and create a motion link

02:46

first, we'll create a motion link between the first revolut joint and the second,

02:51

we need to reverse the direction.

02:52

But because the gears have the same number of teeth,

02:54

we'll be using the relationship of 360 degrees for each revolut joint.

02:59

Then we can repeat this process using motion link one more

03:02

time this time between the center gear and the last gear.

03:07

It is important to note that the motion link

03:09

doesn't need to be between gears that are connected.

03:12

For example, we could use the first joint

03:15

and the last joint.

03:16

These gears are gonna rotate the same direction based on the gear relationship or we

03:21

could create it between the second gear and the third using the reverse option.

03:26

Now, if we rotate one of the gears,

03:28

all three are going to move based on our motion link.

03:32

Let's go back to a home view and make sure that we save the design before moving on.
