ME 362 — Vibrations I
BSc BSc Mechanical Engineering · Kwame Nkrumah University of Science and Technology
Objectives As students complete this course, should be able to Provide the detailed descriptions of the various machine elements that are typically used in power transmissions: belt drives, chain drives, gears, and housings to hold all the elements together. Learn the important features of these elements and the methods of analyzing and designing them. Provided on how the various elements interact with each other. How gears are mounted on shafts, how the shafts are supported by bearings, and how the bearings must be mounted securely in a housing that holds the system together. Develop a completed design that must function as an integrated unit. Content Clutches, Brakes, Couplings, and Flywheels: Static Analysis of Clutches and Brakes: Internal Expanding and External Contracting Rim Clutches and Brakes; Type of Clutches and Brakes; Energy Considerations; Temperature Rise; Friction Materials; Miscellaneous Clutches and Couplings; Flywheels. Flexible Mechanical Elements: Belts; Flat- and Round-Belt Drives; V Belts; Timing Belts; Roller Chain; Wire Rope; Flexible Shafts. Gears Geometry: Types of Gears; Nomenclature, Conjugate Action and Involute Properties; The Forming of Gear Teeth; Gear Trains; Force Analysis. Spur and Helical Gears: The Lewis Bending Equation; AGMA Stress and Strength Equations; Bevel and Worm Gears: Bevel Gearing—General; Bevel-Gear Stresses and Strengths; AGMA Equation Factors; Straight-Bevel Gear Analysis; Design of a Straight-Bevel Gear Mesh; Worm Gearing—AGMA Equation; Worm-Gear Analysis; Designing a Worm-Gear Mesh; Buckingham Wear Load. Power Transmission Case Study: Design Sequence for Power Transmission; Power and Torque Requirements; Gear Specification; Shaft Layout; Force Analysis; Shaft Material Selection; Shaft Design for Stress; Shaft Design for Deflection; Bearing Selection; Key and Retaining Ring Selection; Final Analysis.
