It expounds the necessity and reason of CJK series CNC machine tool servo system comprehensive loss of momentum and the influence on machining accuracy. It calculates the normal gear backlash of the virtual variation principle and the non backlash meshing equatiora Researches on the calculation method and formula of unilateral gear side clearance of gear transmission; through the analysis of the mechanical transmission chain relationship, calculates method of the gap degree and driving system and gap closed loop transmission system on stability and accuracy of the system. By means of analysis method for linear elasticity theory based on materials, points out the role and calculation formula of screw compression caused by the loss of momentum in the workbench, summarizes the work table calculation steps caused by the comprehensive loss of momentum in the gap tooth transmission side and the worktable system linear elastic compression deformation. The example analysis demonstrates the practical application method of CJK series CNC machine tool servo system comprehensive loss of momentum calculation steps for maintenance and repair, design, engineering and technical personnel use and reference.
