经济型数控机床主传动系统的运动设计

The Movement Design of the Main Transmission System for Economic Numerical Control Machine Tool

分析了变频调速交流电机的功率特性和转矩特性以及主运动为回转运动数控机床的功率特性和扭矩特性 ,提出经济型数控机床主传动系统分段无级变速传动的运动设计原则 ,并就几种设计情况进行了分析 .

This paper analyzes the power character and torque character for frequency conversion timing AC motor,and the power character and torque character for the spiddle of machine tool whose main movement is rotation.Some designing principles are brought forward on the subsection stepless variable drive for main transmission system of economic numerical machine tool,and the analyse are carried out on the designs and calculations in different cases.
