Displays the factor of safety to pressure. You can
display the pressure at any point of the cam by
Pressure
choosing Simulation and dragging the mouse
pointer over the motion graphs.
Displays the resonance frequency and the safety
against resonance effects.
Frequency
Displays the loads on the shaft as well as the neces-
sary drive power for the cam. You can display the
Shaft
shaft loads at any point of the cam by choosing
Simulation and dragging the mouse pointer over
the cam.
Displays the stress on the arm. You can display the
arm stress at any point of the cam by choosing
Arm
Simulation and dragging the mouse pointer over
the cam.
Displays the middle normal force on the bearing.Bearing
Displays the results of the spring calculation. You
can display the results at any point of the cam by
Spring
choosing Simulation and dragging the mouse
pointer over the cam.
Generates a 3D body of the cam.3D Cam
The Calculation button gives you the results of your design. To optimize
your design, you can choose to generate the correct size of the cam based
on the pressure angle and the radius of curvature.
To generate a cam design based on pressure angle and radius of curvature
1 Click the Calculation button.
To optimize the size of the cam, the pressure angle from your design must
be less than or equal to a certain value (automatically calculated and
displayed at the bottom of the cam Design and Calculation dialog box)
while the radius of curvature must be greater than or equal to a certain
value (automatically calculated and displayed at the bottom of the cam
Design and Calculation dialog box).
2 Click the Results button.
3 In the Geometry tab, click the Center of Cam button.
Two hatched open triangles are displayed on the screen.
