Chapter 15. Cams

Chapter Objectives

• Learn how to use the Disc Cam tool located on the Power Transmission panel under the Design tab

• Learn how to create and use displacement diagrams

• Learn how to insert cams into assembly drawings

Introduction

This chapter explains how to draw and design cams. Cams are eccentric objects that convert rotary motion into linear motion. Cams are fitted onto rotating shafts, and lift and lower followers as they rotate.

cam: An eccentric object that converts rotary motion into linear motion.

Cams can be designed and drawn using the Disc Cam tool. Displacement diagrams are defined and cams are generated from the displacement diagrams. The shape of the cam’s profile causes the follower to rise and fall as ...
