Download or read book Topology of Modified Helical Gears and Tooth Contact Analysis TCA Program written by Faydor L. Litvin and published by . This book was released on 1989 with total page 164 pages. Available in PDF, EPUB and Kindle. Book excerpt: The contents of ths report covers: (i) development of optimal geometry for crowned helical gears; (ii) method for their generation; (iii) tooth contact analysis (TCA) computer programs for the analysis of meshing and bearing contact and guarantee the favorable shape and low level of the transmission errors. Two new methods for generation of the crowned helical pinion surface have been proposed. One is based on application of the tool with a surface of revolution that slightly deviates from a regular cone surface. The tool can be used as a grinding wheel or as a shaver. The other is based on crowning pinion tooth surface with predesigned transmission errors. The pinion tooth surface can be generated by a computer controlled automatic grinding machine. The TCA program simulates the meshing and bearing contract of misaligned gears. The transmission errors are also determined. Keywords: Helical gears; Crowned gears; Gear geometry; Tooth contact analysis. (JES).

Book excerpt: This book presents papers from the International Conference on Power Transmissions 2016, held in Chongqing, China, 27th-30th October 2016. 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 a range of applications. The presented papers are catalogued into three main tracks, including design, simulation and testing, materials and manufacturing, and industrial applications. The design, simulation and testing track covers topics such as new methods and designs for all types of transmissions, modelling and simulation of power transmissions, strength, fatigue, dynamics and reliability of power transmissions, lubrication and sealing technologies and theories, and fault diagnosis of power transmissions. In the materials and manufacturing track, topics include new materials and heat treatment of power transmissions, new manufacturing technologies of power transmissions, improved tools to predict future demands on production systems, new technologies for ecologically sustainable productions and those which preserve natural resources, and measuring technologies of power transmissions. The proceedings also cover the novel industrial applications of power transmissions in marine, aerospace and railway contexts, wind turbines, the automotive industry, construction machinery, and robots.

Download or read book Novikov Conformal Gearing written by Stephen P. Radzevich and published by Springer Nature. This book was released on 2022-11-14 with total page 485 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book presents the latest accomplishments in Novikov/conformal gearing as well as high-conformal gearing. It is focused primarily on strength calculation of gear teeth and the manufacturing of gears for Novikov/conformal and high-conformal gearing along with a brief discussion of achievements in the modern theory of gearing. The modern theory of gearing is the foundation of all optimal designs of gears, gear-sets, and transmissions of all known designs, as well as, of all those to be developed in the future. As even a small improvement in efficiency on a single gear can represent a significant cost saving, given the millions of gears used in industry every year, this volume provides the design and manufacturing engineer in invaluable resource.

Available in PDF, EPUB and Kindle. Book excerpt: This book presents recent developments in the theory of gearing and the modifications in gear geometry necessary to improve the conditions of meshing. Highlighted are low-noise gear drives that have a stable contact during meshing and a predesigned parabolic transmission error function that can handle misalignment during operation without sacrificing the low-noise aspects of operation. This book also provides a comprehensive history of the develoment of the theory of gearing through biographies of major contributors to this field. The author's unique historical perspective was achieved by assiduous research into the lives of courageous, talented, and creative men who made significant contributions to the field of gearing.
