Abstract
Of this study is the design of the transmission tools of CNC machine , mechanical transmission gear under the influence of external factors and the factors driving accuracy will greatly reduce the Accuracy, such as geometric accuracy and deformation of the thermal deformation of machine tools, as well as the movement between the friction and the transmission gap. These are the transmission accuracy of CNC machine tools, I am also from this start begin to improve the transmission accuracy of CNC machine tools, from all aspects.I completed the design include the formulation of some of the raw data, according to the parameters of the proposed transmission scheme compared to determine the transmission scheme. Then calculate the transmission ratio of the pair and gear of the transmission, and then estimate the modulus of the gear and the axis of the shaft, and gear and shaft strength and stiffness of the check. In addition, we must design the main structure of cabinets, some parts of the selection, thus completing the design of the mechanical drive system as a whole.Keywords: accuracy of CNC machine tool drive system design
