It needs continuous and stable operation under high temperature and high pressure for a long time. Based on the conventional mechanical design, the reliability optimization mathematical model of the planetary gear reducer for submersible oil was established by using the reliability theory and computer optimization method. The optimal design parameters were sought through the optimization algorithm of Matlab software, so as to further reduce the reducer diameter and increase The purpose of increasing daily output and lengthening the pump inspection period has generally raised the economic benefits of crude oil exploration.
