Part 7 Modeling The Circlip
The
circlip is possibly the easiest of the parts to model. We will start by
inserting a Plane object to form the circlip.
|
|
|
|
|
|
|
|
|
|
|
|
 |
Go into front view NumPad-1 and spin
the vertices around the bearing centre. In the Mesh Tools panel Set
Degr:360
Step:64.
Press
spin to form the 3D ring. |
|
 |
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. |
|
|
|
|
|
|
|
 |
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.
|
|
 |
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. |
|
|
|
|
|
|
|
 |
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.
Using the bevel centre script detailed in part 4 add a
0.05mm fillet. |
| Select
all the vertices A and
in the Mesh Tools panel press "Set Smooth". |
|
 |
Finish the circlip by
adding an Edge Split modifier with the default settings as detailed in part 4 |
|
|
|
|
|
|
|
 |
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
and select
"X Local ". The copied circlip will be mirrored onto the other side of
the bearing.
In the outliner select Plane and then in the Links and Materials panel
re name it OB:608-CirclipA. Select Plane.001 and rename it
OB:608-Circlip B |
|
 |
|
|
|
|
|
|
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-W and save your
work. |

| The
completed bearing is ideal for producing visualizations or detailed
drawings but with over 26,000 vertices it will require a lot of you
computers resources if you have many of these in an assembly.
My CNC machines assembly model will require 60 bearings and at this
level of detail that gives over 1.5 million vertices far more than my
old PC can handle, so Part 8 will show how to retain the precision of
the design but with substantially fewer vertices. | |
