6A2: Rotating Cam & Flat-faced-Follower

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 slides along a fixed straight axis.  

Rotating Cam-Follower :

the output rotates about a fixed axis.

Reciprocating :

a non-progressive, translating motion, along a fixed axis.

Oscillating :

a non-progressive, rotating motion, around a fixed axis.

Non-Progressive motion :

a motion that returns to its original position after each machine cycle.

Flat-faced Cam-Follower :

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.a Slider for the Translating Cam-Follower, and

b.a Rocker for the Oscillating Cam-Followers.

2.Add a Profile to the Slider / Rocker to represent the Flat-Faced Cam-Followers

3.Add a continuously rotating Crank as the cam shaft.

4.Add the 2D-Cam element

This tutorial can take 3 minutes.
