Dynamic Tooth Loads and Stressing for High Contact Ratio Spur Gears,

reportActive / Technical Report | Accession Number: ADP000727 | Need Help?

Abstract:

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.
