Abstract
Notice of Retraction
After careful and considered review of the content of this paper by a duly constituted expert committee, this paper has been found to be in violation of IEEE´s Publication Principles.
We hereby retract the content of this paper. Reasonable effort should be made to remove all past references to this paper.
The presenting author of this paper has the option to appeal this decision by contacting TPII@ieee.org.
The transmission of tracked vehicles performs complex functions as steering, shifting, braking, etc. and the system level life time has been influenced by the number of sub-parts such as gear assembly, torque converter, clutches, bearings and so on. In particular, the mechanical type steering system in a tracked vehicle has impact shock torques in steering shift and this kind of shock torques can affect the durability of many sub-parts in power train system. The field failure modes of gear assembly, steering assembly and the bearings of output shaft appear as a very complex phenomenon. In this study, the actual failure, which may occur in field, of the transmission was investigated comprehensively and that the endurance test on the resulting output shaft bearing failure analysis and life assessment was performed. The life time test method used in this study, which was developed for the purpose of internal usage. Under these testing techniques the impact of each bearing damage, which was used in the tracked vehicle transmission left and right output shafts of different structures, was analyzed.
