Abstract

Abstract: In order to improve the production automation, intelligence level and production efficiency of the tractor rear axle, the spiral bevel gear mesh entity based on the virtual collision body is constructed to carry out the human-machine interaction virtual simulation experiment of the tractor rear axle. The spiral bevel gear made by Gleason as is taken an example, the processing technology of arc spur gear is analyzed, the kinematics is used to establish a mathematical model of the spiral bevel gear forming process. The differential and interpolation methods are used to fit the gear curve and surface, the contour point set of the spiral bevel gear is solved, the mesh entity and collision body of the spiral bevel gear are constructed, and the contour accuracy of the mesh entity is verified by the curvature test. The results show that the algorithm can accurately fit the contour of Gleason spiral bevel gears.
