A Treatise on Gear Wheels by George B. Grant Pdf

To most mechanics a gear is a gear."A yellow primrose by the shore, A yellow primrose was, to him And it was nothing more;"And, in fact, the gear is often a gear and nothing more, sometimes barely that. But, if the mechanic will look beyond the tips of his fingers, he will find that it can be something more; that it is one of the most interesting objects in the field of science research, and not the simplest one; that it has received the attention of may celebrated mathematicians and engineers; and that the study of its features will not only add to his practical knowledge, but also to his entertainment. There is an element in mathematics, and in its near relative, theoretical mechanics, that possesses an educating and disciplining value beyond any capacity for earning present money. The thinking, inquisitive student of the day is the successful engineer or manufacturer of the future. The book is filled with wonderful turn of the century illustrations of gear wheels and gear cutting of every description.

Direct Gear Design by Alexander L. Kapelevich Pdf

Over the last several decades, gearing development has focused on improvements in materials, manufacturing technology and tooling, thermal treatment, and coatings and lubricants. In contrast, gear design methods have remained frozen in time, as the vast majority of gears are designed with standard tooth proportions. This over-standardization signif

International Gear Conference 2014: 26th-28th August 2014, Lyon by Philippe Velex Pdf

This book presents papers from the International Gear Conference 2014, held in Lyon, 26th-28th August 2014. Mechanical transmission components such as gears, rolling element bearings, CVTs, belts and chains are present in every industrial sector and over recent years, increasing competitive pressure and environmental concerns have provided an impetus for cleaner, more efficient and quieter units. Moreover, the emergence of relatively new applications such as wind turbines, hybrid transmissions and jet engines has led to even more severe constraints. The main objective of this conference is to provide a forum for the most recent advances, addressing the challenges in modern mechanical transmissions. The conference proceedings address all aspects of gear and power transmission technology and range of applications (aerospace, automotive, wind turbine, and others) including topical issues such as power losses and efficiency, gear vibrations and noise, lubrication, contact failures, tribo-dynamics and nano transmissions. A truly international contribution with more than 120 papers from all over the world A judicious balance between fundamental research and industrial concerns Participation of the most respected international experts in the field of gearing A wide range of applications in terms of size, power, speed, and industrial sector

Fishing gear recycling technologies and practices by Food and Agriculture Organization of the United Nations Pdf

This document is a report on the technical aspects and current examples of fishing gear recycling as an option for end-of-life fishing gear waste management and pollution control. The report also discusses fishing gear recycling options in the context of circular economy and Extended Producer Responsibility (EPR) principles. This report will be used for knowledge sharing, dissemination and capacity building purposes. It will assist with planning of GloLitter Partnerships pilot projects around cost–benefit analyses for end-of-life fishing gear port reception facilities, which can support fishing gear recycling. It will also assist with planning of GloLitter Partnerships phase II “pilot projects” to practically implement the proposed fishing gear recycling management systems and incentive schemes. The objectives the report are: summarize current fishing gear recycling technologies; share global case studies of fishing gear recycling initiatives; review the application of circular economy and Extended Producer Responsibility (EPR) principles to fishing gear recycling; discuss trade-offs between available fishing gear recycling options, and recommend best practices for fishing gear recycling under differing socioeconomic and environmental contexts that progress circular economy and EPR principles.

Manual on Estimation of Selectivity for Gillnet and Longline Gears in Abundance Surveys by Holger Hovgêrd,Food and Agriculture Organization,Hans Lassen Pdf

This manual defines methods for estimating selectivity of gillnet and longline gears, with particular reference to the use of these gears in abundance surveys. The manual illustrates how gear design, the basic concepts of size selection and fish morphometric data can be used to model selectivity. Statistical estimation methods are described in detail, and examples given of their application in spreadsheets. The efficient use of these gears in abundance and research surveys is also discussed. Although the manual concentrates on gillnets and longlines, the methods given are general enough to be relevant to any research involving gear selectivity

Near-Net Shape Manufacturing of Miniature Spur Gears by Wire Spark Erosion Machining by Kapil Gupta,Neelesh Kumar Jain Pdf

This work describes an experimental investigation with the aim to evaluate and establish wire spark erosion machining (WSEM) as a viable alternative for high quality miniature gear manufacturing. External spur type miniature brass (ASTM 858) gears with 12 teeth, 9.8 mm outside diameter and 5 mm face width were manufactured by WSEM. The research work was accomplished in four distinct experimental stages viz., preliminary, pilot, main and confirmation. The aim, scope and findings of each stage are progressively presented and discussed. In essence, the investigation found that it was possible to manufacture miniature gears to high quality by using WSEM. Gears up to DIN 5 quality with a good surface finish (1.2 μm average roughness) and satisfactory surface integrity were achieved. The results suggest that WSEM should be considered a viable alternative to conventional miniature gear manufacturing techniques and that in some instances it may even be superior. This work will prove useful to researchers and professionals in the field of miniature and micro-scale manufacturing and machining.
