Power transmitting machine elements – design and optimization

Overall Course Objectives

The aim of this course is to give the students:
– An overview of machine elements for power transmission.
– An overview of the methods for analysis and design of power transmitting machine elements.

Elaborate on power transmitting elements’ loading and operating conditions.
Apply governing kinematics and kinetics laws in contact driven power transmission.
Explain the reasons for and consequences of power loss.
Dimension machine elements with respect to strength and lifetime (fatigue/wear).
State requirements to functional surfaces for components.
Dimension gears according to standards and by use of software.
Argue about the validity range of analysis methods for dimensioning of machine elements, including DS-, DIN-, EN-, and ISO-Standards.
Use differential geometry for the understanding of contact driven motion in power transmitting machine elements.
Identify the most important types of modern electric motors and state their essential characteristics.

Power transmission systems and components.

Analysis and design of clutches, brakes, couplings, belt drives, gear transmissions and planar mechanisms.

Categorization of power transmitting elements based on specific criteria, i.e. working principle, standardization, price, weight, power losses, lifetime and requirements from the associated machinery system.
