Introduction: Designing Parts of the Wheel Assembly(for Rockies)
This is a final Tad class instructable about making a wheel.
For my part, I am focussing on making individual parts. You will find another instructable on how to assemble these parts on the instructable website.
we will go through making individual parts.
A fully functional laptop with an updated Autodesk inventor (2019 and above)
previous knowledge in inventor might be needed or with common sense, you can follow along.
Step 1: Base Plate Sketch 1
Draw the sketch as shown in the picture.
Note: make it symmetric on the y-axis
Step 2: Excluding Base Feature
this a follow up the step from step 1
choose the exclusion command
choose the symmetric option of 78 mm
Step 3: Holes on the Base Plate
Draw four holes as shown below using the circle option and use these dimensions to contain it as shown above.
Note: make the circles symmetric on the two axis
Step 4: Excluding Step 3
select the exclusion command and choose the cut feature
select cut through all
Step 5: Baseplate Fillets
Select the fillet command and select four corners as shown in the image
Step 6: Part 2(Wheel)
the first sketch of the wheel.
make the following diagram.
using linear diameter on this part. and use construction lines
apply constraints as shown in the image
Step 7: Wheel Extrusion
For this, we are to select the revolution command
choose the angle to be 360 not 270 as shown
Step 8: Fillets Around the Wheel
Choose the fillet command and select the edges as shown.
radius =3 mm
and don't forget the bottom.
Step 9: Part 3 (Bracket)
The most challenging out of the four parts.
I will take 9 steps to do all the features.
starting with this
draw the first sketch and constraint it as in the image
Step 10: Excluding the Sketch From 9
select the exclusion command
do as in the image.
12 mm depth
it should be toward the back( vital for next features)
Step 11: Incline Feature
select the sketch command and choose the y-z plane as shown.
it should be from base to top( the hanging cylinder).
Step 12: Excluding the Inclined Feature
select the exclusion command
and exclude symmetric as shown
Step 13: the Main Body
rotate the diagram and draw a sketch on the back of the incline.
only use the dimension given
to make the drawing symmetric use the tangent constraints.
Step 14: Exclude Connecting Sketch
exclude 10 mm as shown
Step 15: the Base of the Bracket
on the feature from 14, draw the sketch in the image
Step 16: Excluding the Base
do as in the image
Step 17: Bracket Round Fillet
select the fillet command
select the two front edges
Step 18: Edge Smoothing Fillets
choose the fillet command
and choose all the edges shown
Step 19: Hole and S Face
choose the hole command
select commands as in photos.
Step 20: Part 4 (Axel)
start a new part and sketch a circle of 20 mm
exclude it 78mm as shown symmetrically
select new sketch
choose the XY-lane
center point circle and exclude 55mm symmetric
Step 22: Final Step Chamfer on Axel
Select the chamfer feature.
repeat on the backside too
