| Outline and Purpose of the Course | For any machines, prime movers and powertrains are necessary to realize the required functions. In automobiles, an engine is the prime mover and a transmission, a clutch, and a shaft are parts of the powertrain. In machine tools, a motor is used as the prime mover and the powertrain uses feed screws. In this lecture, the prime mover is taken up. Types, characteristics, principles, advantages and disadvantages of the prime mover are explained. Students also learn the basics of tribology, surfaces and contacts, friction, wear, lubrication theory, dynamic guide, hydrostatic guide, rolling guide, oil seal, mechanical seal, packing. | |||
| Course Goals | Understand the principles and basic characteristics of the prime movers and tribology taken up in the lecture. | |||
