Machine element I, 2.5 credits

The idea is to introduce students to Machine Elements including product development (machine design). This is done in lecture form where an orientation and description is given for the basic conditions for achieving a functioning machine. In addition, there is a practical exercise that involves dismantling and analyzing a machine and reassembling it, listing which machine elements the machine is built of, and answering how the designer has thought in terms of economy, environment, destruction, quality etc. The following points are addressed in the course:

• Product Planning
• Product development
• Analytical methods
• Functional ability
• Damage mechanisms
• Instability
• Form and force-dependent function
• Efficiency
• Design criteria including sustainability, environmental aspects, economy…
• Tribology (friction, abrasion, lubrication)
• Tolerances and fits
• Screws and screw joints
• Press and shrink fits
• Keyed connection
• Glued joints
• Welded joints
• Riveted joints
• Springs
• Shafts, shaft couplings, seals
• Machine dynamics
• Critical speed
• Static and dynamic balancing
• Start of machines
• Gears
• Helical Gears
• Planetary Gear
• Belt drives
• Derailleur gears
• Bearings
• Clutches
• Breaks
• Mechanisms
