Studying the load carrying capacity of spur gear tooth flanks
Abstract
The impact of load distribution in meshed teeth, teeth geometry and manufacturing accuracy on wear of the spur gear tooth flanks is studied in this paper. The original geometry of teeth is impaired wearing. Due to that, the load distribution is uneven, dynamic forces are increased, and energy efficiency is decreased. The aim of the theoretical and experimental studies, carried out in this paper, is to reach more accurate model for the analysis of tooth flanks load carrying capacity, taking into account a larger number of impacts on the tooth flanks stress state. A mathematical model for the contact stress during contact period is developed, depending on the value and sign of base pitch difference of meshed teeth. The impact of pitch point's position during the meshed teeth contact period was observed. In order to establish a correlation between the tooth flank failures and developed mathematical model, the appropriate experimental studies were carried out. The cemented spur gear pairs ...were examined on back-to-back gear test rig under conditions of maximum operational load. The results are presented in this paper.
