Overview

Machine design is a large subset of study under mechanical engineering design which includes design of common components used in machines.This is a mega-course of 3 courses in 1 which covers multiple aspects of design of Shafts and elements which are generally mounted it - Bearings and Gears.It is a deep dive into the Shaft design process and selection also deals with the Bearing selection in detail. Then moving to a deep dive in Gear design with practical CAD design of gears based on input specifications.Topics covered: Shaft and layout designBasics of simple power transmission system design Loads and Load casesMaterials and manufacturing of shaftsBasics of Shaft design Layout scheme and General lay outingKeys and key waysSet screws and collarsSplines and Serrations design selection based on standardsInterference and press fitsStress analysis - method of analysis Incorporation of stress concentration factorsNotch sensitivity in fatigue Endurance limit and modifying factorsDeflection and SlopeStress due to interference fitsTorque capacity of press fitsSolid vs Hollow shafts and CouplingsBearing SelectionFactors which drive Bearing selectionContact stresses studyBearing life equation derivation and L10 lifeModified Life - FactorsContamination factor, viscosity ratioDetermining equivalent bearing loadMounting schemeExample to go through the selection processGear design Conjugate action in GearsInvolute profile constructionSpur gear design basics and CAD workflow (fusion 360) Contact Ratio and Interference Basics of Helical gear design and CAD workflow (fusion 360) Basics of Bevel gear design and CAD workflow (fusion 360) Basics of Worm gear design and CAD workflow (fusion 360) Force analysis of spur gearForce analysis of Bevel gearForce analysis of Helical gearForce analysis of Worm gearStress calculations for standard tooth profilePitting equationsThe course is intended to be a library of knowledge regarding machine components and will be expanded further in the future with more examples and case studies.
