Module 3 - Design of Mechanical Elements

Chapter 7: Shafts & Shaft Components

Chapter 7 Overview

Chapter 7 covers the following key concepts:

  • Shaft design
  • Critical speeds for shafts
  • Miscellaneous shaft components
  • Limits and fits


Lecture 16A

In case you missed it, here's a video of the first part of lecture 16. In this video, we introduce the fundamentals of shaft design and explore best practices for ensuring strength, durability, and performance.


Lecture 16B

In case you missed it, here's a video of the second part of lecture 16. In this video, we take a deeper dive into the vibration characteristics of shafts and why understanding critical speed and natural frequency is essential for designing reliable rotating systems.


Lecture 16C

In case you missed it, here's a video of the third part of lecture 16. In this video, we explore how to securely couple hubs to shafts using keys and splines. These connections are critical in power transmission, and understanding their design considerations helps prevent failures.


Lecture 16 Tasks

In this lecture, we will learn about the design of shafts and shaft components (e.g. gears, pulleys, belts, keys). Some common best practices and design considerations will be discussed.
