6A2: Rotating Cam & Flat-faced-Follower
Contents
Rotating Flat Cams with Flat-Faced-Followers
To add a 2D-Cam, you must select two elements:
| • | Part - which becomes the Cam-Part. |
| • | Profile/Extrusion - which becomes the Cam-Profile. |
Before you can add a 2D-Cam, you must prepare the model to include these two elements. You must also specify the motion for each.
Terminology:
Cam Terminology : |
Description and definition. |
Translating Cam-Follower : |
the output Part that slides along a fixed straight axis. |
Rotating Cam-Follower : |
the output Part that rotates about a fixed axis. |
Reciprocating : |
a non-progressive, translating motion, along a fixed axis. |
Oscillating : |
a non-progressive, rotating motion, around a fixed point. |
Non-Progressive motion : |
a motion that returns to its original position after each machine cycle. |
Flat-faced Cam-Profile : |
a planar surface in continuous-contact with the Cam. |
Objective
| • | Design a Cam to move a Reciprocating Cam-Follower, with a Flat-Faced Cam-Profile. |
| • | Design a Cam to move an Oscillating Cam-Follower, with a Flat-Faced Cam-Profile. |
Short Summary of this Tutorial
| 1. | Model two different kinematic-chains: a Slider for the 'Translating' Cam-Follower, and a Rocker for the 'Oscillating' Cam-Followers. |
| 2. | Add a Profile to represent the Flat-Faced Cam-Follower to the Slider / Rocker |
| 3. | Add a continuously rotating Rocker (Crank) as the cam - a Cam-Shaft. |
| 4. | Add the 2D-Cam element |
This tutorial can take 3 minutes.
