摘要：
The machine tool errors are the main causes of tooth surface errors of curvilinear gear. The research on the relationship between machine tool errors and tooth surface errors will provide theoretical basis for the reverse calculation of machining parameters and the error correction of tooth surface. Based on the forming principle of curvilinear gear, the structure model and the coordinate system of curvilinear gear machine tool are established. The overall errors of curvilinear gear machine tool are described by the position errors between gear blank and cutter head, and the shape errors of cutter. Based on the meshing principle, the tooth surface equation is derived when machine tool is with or without errors. The calculation method of error surface for curvilinear gear is studied. The error surfaces under different machine errors are analyzed by using the second-order approximate surface and the average error influence coefficient of tooth surface. And the influence law of machine tool errors on tooth surface errors is studied. The influences of machine tool errors on errors of gear concave tooth surface are analyzed by examples when the geometric parameters of the gear are constant and changing. © 2020 Journal of Mechanical Engineering.
