Aachen Forum on Gear Production by Thomas Bergs,Christian Brecher Pdf

Although gears have been indispensable components in various sectors such as mechanical engineering, automotive engineering and industrial gear manufacturing for many decades, increasing requirements and current market developments are constantly presenting the transmission technology industries with new challenges. In modern gear transmissions, competition, besides the price, is determined by load-carrying capacity, operational reliability and noise excitation behavior. In the automotive industry in particular, reliable transmissions with high power density, low weight and minimal noise emissions are required. The current trend towards e-mobility, as well as general ecological and economical challenges to improve resource efficiency, lead to increased demands on gear quality and surface finish. In this context, the finishing and quality inspection of gears take on central roles. As the finishing of gears has a significant influence on their operational behavior, the reliability of the processes must be continuously ensured with regard to a high quality of the work result. Therefore, at this year's Aachen Forum on Gear Production, which is organized hand in hand by the WZL of RWTH Aachen University and the Research Association Transmission Technology (FVA), the focus is on finishing processes and quality inspection of gears. The spectrum of topics ranges from process and tool design in line with requirements to the manufacturing of individual gear geometries and measures for continuous quality assurance. Aspects of modern finishing processes for the generation of superfinished surfaces, quality inspection during production, and the economic efficiency of production and application are presented. The objective of the Aachen Forum on Gear Production is an exchange of knowledge and experience between engineers who are employed or have responsibility in the design, development, production, assembly, and application of gear drives. The individual technical presentations feature both manufacturers of machines and tools as well as users who report on their own practical experience. In addition, there are interesting presentations by research experts.

Light Weight Materials by Kaushik Kumar,Bathini Sridhar Babu,J. Paulo Davim Pdf

In the automotive and aerospace industries, the need for strong yet light materials has given rise to extensive research into aluminum and magnesium alloys and formable titanium alloys. All of these are categorized as light weight materials. The distinguishing feature of light weight materials is that they are low density, but they have a wide range of properties and, as a result, a wide range of applications. This book provides researchers and students with an overview of the recent advancements in light weight material processing, manufacturing and characterization. It contains chapters by eminent researchers on topics associated with light weight materials, including on the current buzzword “composite materials”. First, this book describes the current status of light weight materials. Then, it studies applications of these materials, given that, as the densities vary, so do the applications, ranging from automobiles and aviation to bio-mechatronics. This book will therefore serve as an excellent guide to this field.

Theory of Gearing by Stephen P. Radzevich Pdf

The first book of its kind, Theory of Gearing: Kinematics, Geometry, and Synthesis systematically develops a scientific theory of gearing that makes it possible to synthesize novel gears with the desired performance. Written by a leading gearing expert who holds more than 200 patents, it presents a modern methodology for gear design. The proposed theory is based on a key postulate: all the design parameters for an optimal gear pair for a particular application can be derived from (a) a given configuration of the rotation vectors of the driving and driven shafts and (b) the power transmitted by the gear pair. This allows engineers to synthesize the desired gear pairs with only the following input information: The rotation and torque on the driving shaft The configuration of the driven shaft in relation to the driving shaft The desired rotation and torque of the driven shaft Beginning with the fundamentals, the book reconsiders the basic theory of kinematics and geometry of gears to provide a sound basis for the evaluation and development of future designs. It then examines ideal and real gearing for parallel-axis, intersected-axis, and crossed-axis gearing. The book addresses how to minimize vibration and noise in gears, discusses aspects of implementing the theory of gearing, and analyzes principal features of power transmission and the loading of gear teeth. More than 500 figures clearly illustrate the principles. This is an invaluable resource for engineers and researchers who work in gear design, gear production, and the application of gears as well as for students in mechanical and manufacturing engineering. Covering all known gear designs, this book offers an analytical solution to the problem of designing optimal gear pairs for any given application. It also encourages researchers to further develop the theory of gearing.
