Multi-condition and Multi-objective Modification Optimization Design of Spur Gear
Abstract
Considering that spur gears are used under multiple-condition， the modeling method of modified tooth surface for pinion and the multi-condition and multi-objective modification optimization methods of the spur gear transmission are researched. The multi-condition and multi-objective modification optimization design of spur gear transmission under two working conditions is carried out， and the modification optimum design and unmodified tooth surface meshing simulation of a spur gear transmission system are carried out. It is verified by comparison that the spur gear transmission with modification optimization have good comprehensive performance， and its fluctuation amplitude of loaded transmission error as well as maximum flash temperature decrease obviously in both situation. The research results lay a foundation for modification design to improve the comprehensive performance of spur gears.
