DYNAMICS OF HIGH-CONTACT-RATIO GEAR SYSTEMS WITH DIFFERENT TOOTH SPACING ERRORS 65AND TOOTH PROFILE MODIFICATIONS

摘要

A computer model validated by experimental results was used to investigate the effectiveness of profile modification for reducing dynamic loads in high-contact-ratio gears with different tooth spacing errors. The computer simulation examined varying amplitudes of spacing error and differences in the span of teeth over which the error occurs. The modification considered included both linear and parabolic tip relief. The dynamic analysis was performed using a revised version of a 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 dynamic performance of high-contact-ratio gear sets with different tooth spacing errors.
