LEARNING MODULE

Mechanical Design

Build a sound understanding of moving machinery, parts, calculations, and practical mechanical integration.

WHAT YOU WILL LEARN

Learn how motor-driven mechanisms are supported, sized, assembled, checked, and maintained.

Read in sequence when you want a guided course, or open a published lesson directly. Titles marked “In editorial review” belong to the approved catalogue but are not presented as finished manuscripts.

MODULE LEARNING PATH

  1. 01 From a Motor to a Moving CarriageIn editorial review Meet the basic parts of a linear-motion system and understand their separate jobs.
  2. 02 Inside a Ball ScrewIn editorial review Understand the screw, nut, balls and supporting components that turn rotation into travel.
  3. 03 Lead Screw Versus Ball ScrewIn editorial review Compare thread lead, pitch, friction and motion trade-offs.
  4. 04 Supporting and Protecting a Long ScrewIn editorial review Learn why screw-end support, critical speed and buckling limits matter.
  5. 05 Linear Guides and Their Load RatingsIn editorial review See how rails, carriages and moments support machine loads.
  6. 06 Rails, Shafts and Small Supporting PartsIn editorial review Choose between common guiding styles and identify supporting mechanical hardware.
  7. 07 How Assembly Errors Damage Motion SystemsIn editorial review Recognize misalignment, inappropriate constraints and poor mechanical integration.
  8. 08 Selecting a Complete Linear AxisIn editorial review Turn travel, load and accuracy requirements into a defensible component shortlist.

  1. 09 What Shaft Couplings Actually DoIn editorial review Learn the anatomy and families of couplings joining rotating shafts.
