Download or read book Spur Gears Optimal Geometry Methods for Generation and Tooth Contact Analysis TCA Program written by Faydor L. Litvin and published by . This book was released on 1988 with total page 170 pages. Available in PDF, EPUB and Kindle. Book excerpt: The contents of this report covers: (i) development of optimal geometry for crowned spur gears; (ii) methods for their generation; and (iii) tooth contact analysis (TCA) computer programs for the analysis of meshing and bearing contact of the crowned spur gears. The developed method for synthesis is used for the determination of the optimal geometry for crowned pinion surface and is directed to reduce the sensitivity of the gears to misalignment, localize the bearing contact, and guarantee the favorable shape and low level of the transmission errors. A new method for the generation of the crowned pinion surface has been proposed. This method 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 crowned pinion surface can be also generated by a generating plane whose motion is provided by an automatic grinding machine controlled by a computer. The TCA program simulates the meshing and bearing contact of the misaligned gears. The transmission errors are also determined. Keywords: Spur gears; Gears; Tooth contact analysis; Crowned spur gears. (jes).

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).

This book was released on 1989 with total page 1298 pages. Available in PDF, EPUB and Kindle. Book excerpt: Cities and Their Vital Systems asks basic questions about the longevity, utility, and nature of urban infrastructures; analyzes how they grow, interact, and change; and asks how, when, and at what cost they should be replaced. Among the topics discussed are problems arising from increasing air travel and airport congestion; the adequacy of water supplies and waste treatment; the impact of new technologies on construction; urban real estate values; and the field of "telematics," the combination of computers and telecommunications that makes money machines and national newspapers possible.
