ABSTRACT

According to the effect of ring gear assembly on the transmission and the positioning accuracy of heavy duty machine tool worktable, the deformation field of thin-walled ring gear under the effect of press fit force was analyzed. Under the condition of inhomogeneous deformation of ring gear assembly, the force and the coincidence degree in the meshing of the gears and ring gear were utilized to research the deformation of meshing tooth surface and its influence on the meshing accuracy of ring gear, and put forward the assembly process design method for controlling the non-uniform deformation of ring gear. In addition, the experiences of ring gear assembly and worktable precision detection were utilized to confirm the validity of the method. The results showed that the precision of worktable positioning and repeatability positioning meet the design requirements of CXK5463 gantry-moving type turn-milling machining center.
