Power Mechanisms of Rotational and Cyclic Motions

This book assists design engineers in making the design trade-offs and the necessary decisions in the various stages of the design in a wide range of engineering applications. It covers mechanisms of rotational motion; variable speed drives; mechanisms of cyclic motion; lubrication systems; and components of mechanisms. The book provides extensive reference information, while stressing the role of the design engineer throughout, as well as the design trade-offs to be made in practical engineering scenarios.

An offshoot stemming from the author’s previous book detailing the makeup and composition of a machine, Power Mechanisms of Rotational and Cyclic Motions provides an in-depth analysis of machine structure and operation. An important reference for practicing mechanical engineers, this book presents the kinematic diagrams of driving mechanisms in detail, analyzes their motion characteristics and efficiency, and addresses the lubricating problems that impact the reliability and operating life of machines. The diagrammatic representation of mechanisms is accompanied by examples of their general and detailed design, main geometry calculations, and recommendations for an approximate evaluation of principal dimensions. The authors consider the main stages of design, including the choice and analysis of kinematic diagrams, preliminary sizing, embodiment, and the design and dimensioning of specific elements including gears, shafts, bearings, springs, cams, fasteners, and others.

A pivotal work, the book contains details of design that include:

• Analysis of diagrams of mechanisms (for their kinematic effects and efficiency)
• Rough dimensioning of the main elements
• Examples of the design of mechanisms and their elements (with relevant calculations of geometry and for strength)
• Design of specific subassemblies and parts (including their materials and heat treatment)
• Choice and design of lubrication systems

Intended for engineering postgraduates, engineers, and designers of machines, Power Mechanisms of Rotational and Cyclic Motions also describes the main metals used in machinery and their mechanical characteristics and provides expressions for strength calculation. Covering a wide range of mechanisms, it contains numerous examples of design of mechanisms and accompanying calculations and design hints based on the authors’ vast experience.
