It is one of the key factors to ensure NC machine performance by designing a reliable driving and gear mechanism. . At first, on the basis of the demand of overall performance, an infinitely variable transmission with two class gearing is adopted to satisfy the output torque in low speed. According to the design requirements, an AC asynchronous servomotor is used to carry on the stepless transmission and the motor order is decided in response to the rated power and the rated speed. Then the headstocks graduation ratio is computed, the stage number, the speed ratio and the spindle speed range are all determined. The gears and the shafts in the headstock are designed and their stresses are verified. All bearings are selected on various shafts needs. The multi-wedge belt model is selected, and the essential design calculation is carried on. TK6163 NC machine runs well with high performance on account of the infinitely variable transmission’s reasonable design.
