Control System Technology focuses on the processes, methodologies, and techniques employed in control system technology, including digital computers, transducers, actuators, and amplifiers. The book first takes a look at classification, terminology, and definitions, displacement, reference, and velocity of transducers, and strain, force, torque, acceleration, load, and tension of transducers. Discussions focus on strain gauges and measuring bridges, other transducers for measuring force, torque, acceleration, and tension, displacement and velocity transducers, natural control systems, classification of control systems, and generalized single loop continuous feedback control system. The monograph examines electric amplifiers and final control elements, hydraulic and pneumatic amplifiers and final control elements, flow control valves, actuators and positioners, and signal and data conversion. The publication also ponders on interfacing control systems to digital computers, control system performance and commissioning, and experimental testing of plant, system elements, and systems. The manuscript is a valuable reference for engineers and researchers interested in control system technology.

Understanding how gears are formed and how they interact or ‘mesh’ with each other is essential when designing equipment that uses gears or gear trains. The way in which gear teeth are formed and how they mesh is determined by their geometry and kinematics, which is the topic of this book. Gears and Gear Drives provides the reader with comprehensive coverage of gears and gear drives. Spur, helical, bevel, worm and planetary gears are all covered, with consideration given to their classification, geometry, kinematics, accuracy control, load capacity and manufacturing. Cylindrical gear geometry is the basis for dealing with any gear drives, so this is covered in detail. Key features: Contains hundreds of 2D and 3D figures to illustrate all types of gears and gear drives, including planetary and worm gears Includes fundamental derivations and explanations of formulae Enables the reader to know how to carry out accuracy control and load capacity checks for any gear drive Includes directions for the practical design of gears and gear drives Covers DIN and ISO standards in the area Gears and Gear Drives is a comprehensive reference for gears and gear drive professionals and graduate students in mechanical engineering departments and covers everything important to know how to design, control and manufacture gear drives.

Cette bibliographie commentee touche tous les domaines du savoir humain, soit de l'Art a la Zoologie;elle signale les ouvrages les plus importants soit des bibliographies, des index, des encyclopedies, des dictionnaires, des guides, des revues etc dont le support ed'information est soit du papier, soit un cd-rom, soit une base de donnees en ligne directe, soit un microforme ect. L'objectif du guide Walford est de devenir La source d'information sur tout type de reference, nonobstant le support technique.

The book explores the geometric and kinematic design of the various types of gears most commonly used in practical applications, also considering the problems concerning their cutting processes. The cylindrical spur and helical gears are first considered, determining their main geometric quantities in the light of interference and undercut problems, as well as the related kinematic parameters. Particular attention is paid to the profile shift of these types of gears either generated by rack-type cutter or by pinion-rack cutter. Among other things, profile-shifted toothing allows to obtain teeth shapes capable of greater strength and more balanced specific sliding, as well as to reduce the number of teeth below the minimum one to avoid the operating interference or undercut. These very important aspects of geometric-kinematic design of cylindrical spur and helical gears are then generalized and extended to the other examined types of gears most commonly used in practical applications, such as: straight bevel gears; crossed helical gears; worm gears; spiral bevel and hypoid gears. Finally, ordinary gear trains, planetary gear trains and face gear drives are discussed. Includes fully-developed exercises to draw the reader's attention to the problems that are of interest to the designer, as well as to clarify the calculation procedure Topics are addressed from a theoretical standpoint, but in such a way as not to lose sight of the physical phenomena that characterize the various types of gears which are examined The analytical and numerical solutions are formulated so as to be of interest not only to academics, but also to designers who deal with actual engineering problems concerning the gears

All of the critical technical aspects of gear materials technology are addressed in this new reference work. Gear Materials, Properties, and Manufacture is intended for gear metallurgists and materials specialists, manufacturing engineers, lubrication technologists, and analysts concerned with gear failures who seek a better understanding of gear performance and gear life. This volume complements other gear texts that emphasize the design, geometry, and theory of gears. The coverage begins with an overview of the various types of gears used, important gear terminology, applied stresses and strength requirements associated with gears, and lubrication and wear. This is followed by in-depth treatment of metallic (ferrous and nonferrous alloys) and plastic gear materials. Emphasis is on the properties of carburized steels, the material of choice for high-performance power transmission gearing.
