The main drive system of CNC machine tool mainly prises a motor, transmission system and the main ponents, the main transmission system with generalmachine tools pared in structure is relatively simple, because thetransmission unction of all or most of the stepless speed spindle motor to bear, left to a gear transmission mechanism is plex, to expand the range of stepless speed regulation motor there are only two or three stagegear transmission system. It is fixed at the left end of the machine body, a spindle is arranged on the spindlebox (spindleis hollow, the laying of machining and machine line bar can be used not only for the longer the can also increase the rigidity of spindle),chuck,workpiece clamping fixture. Spindle box function is to support and drive spindle, the spindle drives the workpiece isdetermined according to the rotation speed of design rules is the main content of the main parameters of machine, draws up the transmission plan and the transmission system, the main parts of the calculationandchecking.. Key words: CA6140 machine tool spindle box parts transmission 茂名職業(yè)技術(shù)學(xué)院 3 目錄 一、 設(shè)計目的 ....................................................................4 二、 設(shè)計步 驟 ....................................................................4 1. 運動設(shè)計 ..................................................................4 已知
