摘　　要：Continuous generating grinding has become an important gear processing method owing to its high efficiency and precision.In this study,an adaptive design model is proposed for the continuous generation of beveloid gears in common gear grinding machines.Based on this model,a method for determining the installation position and grinding kinematics is developed alongside an analytical meshing model for grinding contact trace and derivation of key grinding parameters.By combining these aspects,a general mathematical model for the continuous generation of beveloid gears is presented,comprising the entire grinding process from worm wheel dressing to the evaluation of grinding deviation.The effects of the worm and dressing wheel parameters on the grinding deviation were analysed,facilitating the development of an approach to improve the grinding accuracy.The presented procedure represents a novel design method for the continuous generation of beveloid gears in common gear grinding machines,facilitating the appropriate selection of worm and dressing wheel parameters.
