According to the output requirements of main transmission system for NC tape winding machine

considering the problems of small range for the spindle constant power and shortage for the output torque

the main transmission system is designed by using sectional stepless speed variation scheme.Considering the influence of winding tension and pressure

spindle motor is initially selected via the motor power of the total starting torque.The main transmission system is designed by using chart of rotate speed and spindle motor should work in the speed range of good output of the power and torque.The gears are chosen reasonably by comparison of torque and power in the overlap regions of power and torque diagram that has been drawn.Arrangement for the whole structure is designed and 3Ddrawing of the transmission system is drawn

the main transmission system design for the NC tape winding machine is accomplished.
