[Abstract]:In the process of NC gear shaper machining, the problem of the deviation of gear pitch deviation is common. Firstly, under the premise of reasonably controlling the geometric accuracy, motion error and positioning accuracy of CNC gear shaper, the root cause of the overdeviation of tooth pitch deviation is the non-synchronization of generating motion. Secondly, a kind of on-line gear precision detecting device is designed to reduce the influence of the installation and measurement error on the measuring accuracy of gear pitch deviation. Finally, based on the influence mechanism of the servo gain parameters on the servo motor control shaft, a large number of orthogonal experiments of gear shafting are carried out by changing the servo gain parameters. It is verified that the unsynchronism of the generating motion of the two rotary shaft in the return position is the fundamental cause of the deviation of the gear pitch in the retraction position. The influence of the servo gain parameters on the deviation of the tooth pitch is analyzed, and the corresponding adjustment strategy is put forward. The research provides a new way to solve the problem of the deviation of gear pitch deviation in NC gear shaper machining.
