SOLIDWORKS Exercise 12

Pulley

Exercise 12: Complete this part using the dimcnsions provided. Use
Pulley relations where applicable to maintain the design
intent.

This lab uses the following skills:

Symmetry in the Sketch on page 121

Mid Plane Extrusion on page 123
Draft Toggle on page 123
Introducing: Circles on page 126

Optional If you would like to usethe existing geometry, skip to Procedure. If

Sketching you would like to create the sketches, open a new mm part and use the
dimensions below. There are three sketches required, the rst created
on the Front Plane, the remaining two on the Right Plane.

2 Hanger.
Use the Hanger (blue) sketch and another Mid-
plane extrusion of 4mm with the sameamount
of draft.

3 Cut and hole.

Create a cut using the Center Cut sketch
(green). The cut is Through All- Both.
Add a 5mm diameter hole.

Create another hole, 3mm, centered above the

origin.

Design Intent Some aspects of the design intent for this part are:
1. The part must remain
symmetrical about the Right
plane.
2. The Transition requires
ats that are driven by the
distance between them.

Procedure Open an existing part.

1 Open the part Ratchet

2 Edit the sketch.

Right-click the Transition feature and click Edit Sketch. Modify the
sketch to add the equally spaced horizontal ats 8mm apart. Exit the
sketch.

3 Edit Feature.
Edit the H End Fillets feature to
add more edges. Select the four
new edges created by the ats.
Click OK.

4 Resulting llets.
The new edges become part of the
llet feature, causing the shape of
the next llet feature to update.

Using Direction of The default extrusion dircction is normal to the pro le or sketch plane.
Extrusion Occasionally a model dictates an extrusion that is not normal to the
pro le, but along a vector using the Direction of Extrusion option.
The vector can be a sketch line, cdge, or axis.
