Experiments and Study of the Static Rigidity of Workpiece Spindle of Direct-drive Gear Hobbing Machine
Static rigidity of workpeice spindle component is a very important index of the rigidity of derict-drive gear hobbing spindle unit.In this study,the static rigidity of workpiece spindle system were analyzed through a finite element method (EFM) by building geometric models and studying the deformation when radial cutting force was imposed.Experiments on workpiece were carried out with and without the assistance of tailstock center separately to measure the changes of the static rigidity of spindle.The results prove a less change of the static rigidity of spindle when with the assistance of tailstock center,which helps to ensure the accuracy and surface roughness of a workpiece.
