Abstract

The dynamic load of gears with regular type of spacing error such as full-sine and half-sine type has been analyzed in several previous research works. In this study, the irregular type of tooth spacing error is incorporated with the regular type ones to determine their effect on gear dynamic response. Linear and Parabolic tooth profile modification are applied to evaluate their influence on the dynamic loads of gear systems with regular or irregular tooth spacing errors. All dynamic analyses are conducted using the NASA gear dynamics code, DANST program.The objective of this study is to examine the relationship between gear dynamic load, type and extent of tooth spacing error, and profile modifications. Results obtained from this study can provide proper tooth profile design to minimize the dynamic response of the spur gear systems for a better transmission design.
