Description

technical field

[0001] The invention belongs to the technical field of mechanical processing technology, and in particular relates to a method for improving the processing precision of an internal gear honing wheel for power honing. Background technique

[0002] In the actual powerful honing process of the internal honing wheel, the motion between the internal honing wheel and the workpiece gear can evolve into an internal meshing transmission between a pair of cross-axis helical gears. The existence of factors such as different grain sizes, different interpolation periods of the CNC system, rigidity of the machine tool motor, machine tool vibration, thermal deformation, etc., causes the workpiece gear to not be a smooth involute surface, and will form certain honing grooves, grooves, etc. The depth and direction of the workpiece have a decisive influence on the profile errors of the tooth surfaces of the workpiece. Theoretical tooth surface groove depth and orientation can...
