Answer:
A machine generally consists of a motor, a drive, and an actuating element. The mechanical power driving a machine constitutes the rotary motion energy of a motor shaft. Electric motors, internal-combustion motors, or turbines are the most common types of motors. The mechanical power transmission from the motor to the actuating element is accomplished by various driving gears. These include gearings, worm gearings, belt drives, chain drives, and friction gears. Some examples of actuating elements are car steering wheels, work spindles, and screw propellers of ships. This chapter covers the advanced design of machine elements, in particular all common types of gearings and the needed machine components. The in-depth description including stress and strength analysis, materials tables and assembly recommendations allows for a comprehensive and detailed calculation and design of these most important drives. Shafts and axles, shaft-hub assemblies and bearings are included with design guidelines and machining options. Single machine elements, such as specific information about bolts and bolted joints, springs, couplings and clutches, friction drives and also sliding bearings are dealt with only where needed for the benefit of a more general view. The chapter provides the practicing engineer with a clear understanding of the theory and applications behind the fundamental concepts of machine elements.
