Orbiting Gear center: There is one fixed Pulley, joined to the Base-Part. The belt path is moves with a rotating Part. The Orbiting Pulleys rotate with a rotating Part around the center of one fixed Pulley on a rotating Part. Each Part can be: •Driving-Pulley Linear Motion of Belt = Driving-Pulley Radius x Driving-Pulley Angular Motion •Driven-Pulley Angular Motion of Pulley = Linear Motion of Belt / Pulley Radius. |
STEP 1: Add a rotating-Part - a Crank
|
|||
|
|||
|
|||
STEP 2: Add a sketch-loop to define the belt-path.
|
|||
STEP 3: Add a Motion FB to the sketch-loop
|
|||
STEP 4: Add a Linear-Motion FB
STEP 5: Add a Part We must add a Part to the other end of the sketch-loop. We will add a Pulley with this Part - see below. |
STEP 1: Click Kinematic-element toolbar > Add Pulley |
||
Add Pulley opens in the Command-Manager.
|
||
MechDesigner adds the Pulley. It is Cyan color. It is a Driving-Pulley.
You must do Add Pulley two(2) x to add a Pulley to each Arc. |
||
STEP 2: Click Kinematic-element toolbar > Add Pulley AGAIN
The Pulley has a Magenta color. This means it is a Driven-Pulley. |
