Part 7 Modeling The Circlip






Insert Plane
The circlip is possibly the easiest of the parts to model. We will start by inserting a Plane object to form the circlip.

In the Outliner set the 608-Race and 608-ShieldA to visible and hide all the other parts. In Object Mode snap the cursor to the 608-Race object to set the cursor in the centre of the bearing.

Go into side view NumPad-3 and ensure the 3D cursor is on the bearing centre.

We will start this object with a plane, so press the Shift-A to open the Add
menu and click Mesh>Plane.
The plane will open in Object Mode
and aligned to top view.
Tab into Edit mode and Rotate the plane 90 degrees
on the Y axis.

Set Position

Grab the plane and position it in the circlip grove of the outer race, resizing it to 0.4 horizontally and 0.75 vertically.

Press X to delete the inner face and choose Only Faces. If the face was left it would form internal geometry and a non manifold mesh.








Spin
Go into front view NumPad-1 and spin the vertices around the bearing centre.

In the Spin options Set
Angle to 360 and Steps to64.

Select and delete Select two loops of vertices through the ring and X delete them to form the opening in the circlip.

Make sure you have selected the vertices on the back edge as well as those on the front.





Rotate from centre To allow the circlip to be prised out with a sharp tool the cut through the circlip is made at an angle.

To form this select the four vertices on the outer edge of the break and rotate R them from the centre of the circlip.
Add Face Rotate your view and select the 4 vertices on one of the open ends.

Press F to insert a face.

Do the same on the other open end.





Select edges Go into edge select mode and loop select the four edge loops forming the inner and outer edge Shift-Alt-RMB.

Select all the edges of the ends.

Bevel the edges as detailed in part 4 add a 0.05mm fillet.
Select all the vertices A and in the Mesh Tools panel press "Set Smooth".
Bevel 0.05 Finish the circlip by adding an Edge Split modifier with the default settings as detailed in part 4





Copy and Mirror To finish off we will mirror this circlip onto the other side of the bearing.

In object Mode go into side view.

Copy the circlip Shift-D then Esc to leave it in the same position.

With the cursor still on the object centre Ctrl-M for mirror then Y
for the mirror axis. The copied circlip will be mirrored onto the other side of the bearing.

In the outliner select Plane and then in the Object panel rename it to 608-CirclipA. Select Plane.001 and rename it to 608-Circlip B
Completed Bearing





That completes the modeling of the components for the detailed bearing. In the outliner open the eye icon for all the parts to bring them into view. (If the components don't appear you may still be in local view, try pressing NumPad-/ to close local view) Rotate the view to see your work.

The Dust Shields cover most of the components so you may want to hide one of the dust shields (Outliner eye icon).

Press Ctrl-S and save your work.
One dust shield removed
