Applied Machine Elements

Catalog description

The theories and methods developed in statics, dynamics, and strength of materials are applied to the selection of basic machine components. The course will develop the fundamental principles required for the selection of the individual elements of which a machine is composed. Typically offered Spring. Prerequisite(s): (MET 21100 FOR LEVEL UG WITH MIN. GRADE OF D- OR MET 21101 FOR LEVEL UG WITH MIN. GRADE OF D- AND MET 21102 FOR LEVEL UG WITH MIN. GRADE OF D-) AND MET 21300 FOR LEVEL UG WITH MIN. GRADE OF D- Course Learning Outcomes 1. Model belt, chain and gear drives and identify the type of loading existing in a power transmission system due to the integration of each type of drive and specify suitable types and sizes of belts and heaves, chains and sprockets, and gear train characteristics to transmit a given level of power at specified speeds for the input and output shafts. 2. Compute the torques and forces exerted on shafts by couplings, bearings, belt, chain and gear drives by utilizing torque diagrams and load, shear and moment diagrams in two orthogonal planes and use the modified 1927 shaft standard equation as proposed by Krutzet al to specify diameter of a shaft exposed to torsional and/or bending moment loads. 3. Categorize examples of mechanical systems based upon the type of component loading existing in the system. 4. Identify various types of rolling bearings, the mounting techniques used with roller bearings and the interference fits required, determine total bearing reactions to due to component loading and assess basic static and dynamic load ratings and life rating for various types of bearings. 5. Compute the forces exerted on gear teeth as they rotate and transmit power and use appropriate stress analysis to determine relationships among applied forces, the geometry of gear teeth, and other specified factors necessary to specify gear parameters including diametrical pitch, number of teeth, tooth width etc., required for various applications. 6. Introduce relationship between polar moment of inertia and mass moment of inertia for solid cylindrical shafts so that the design of a power transmission system may encompass speed of response of the system. 7. Integrate the mechanical concepts necessary to complete a preliminary design of a conveyor system. 8. Install and align a variety of bearings, shafts, couplings, belt, chain and gear drives using laboratory equipment provided and measure and adjust belt tension, chain sag and gear backlash and experimentally verify theoretical relationships governing the speed ratio of belt, chain and gear drives.
