Download or read book Minimizing the Dynamic Load of High Contact Ratio Spur Gear Using Profile Modification written by Srijana Shah and published by . This book was released on 2016 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: One of the major concern in the design of power transmission gear is the reduction of gear dynamic load. Research on gear noise and vibration has revealed that the basic mechanics of noise generated from gearing is gear box vibration excited by the dynamic load. This thesis studies the effect of tooth spacing errors on the dynamic load of high contact ratio spur gear subjected to unideal loading conditions. Spur gear is the simplest kind gear available. Spur gears have their teeth parallel to the axis of rotation and are used for transmitting power between two parallel shafts. Three types of spacing error distribution are defined and studied: type I (short span), type II (medium span), and type III (long span). Three different kinds of modification have been considered: linear, parabolic 1, parabolic II. The range of loading is changed from 0.75 times to 1.25 times of design load which is 2200 lb.-inch. A computer simulation has been conducted to investigate the effectiveness of profile modification for reducing dynamic loads in high-contact-ratio gears with different tooth spacing errors. The simulation examined varying amplitudes of spacing errors and differences in the span of teeth over which the errors occur. The dynamic analysis was performed using a revised version of a NASA gear dynamics code, modified to take into consideration the tooth spacing errors in the dynamic analysis. The findings of this study can be used to design robust tooth profile modification for improving the dynamic performance of high-contact-ratio gear sets with different tooth spacing errors when subjected to unideal loading condition.

This book was released on 2014-09-18 with total page 1225 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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

Download or read book Dynamic Tooth Loads and Stressing for High Contact Ratio Spur Gears written by R. W. Cornell and published by . This book was released on 1983 with total page 12 pages. Available in PDF, EPUB and Kindle. Book excerpt: An analysis and computer program has been developed for calculating the dynamic gear tooth loading and root stressing for HCRG as well as LCRG. The analysis includes the effects of the variable tooth stiffness during the mesh, tooth-profile modification, and gear errors. The calculation of the tooth root stressing caused by the dynamic gear loads is based on a modified Heywood gear tooth stress analysis, which appears more universally applicable to both LCRG and HCRG. The computer program is presently being expanded to calculate the tooth contact stressing and PV values.
