我厂从瑞士雷斯豪威尔(REISHAUER)公司引进的蜗杆磨齿机RZ300E,其工作原理与同一类型的早期产品NZA一样,均采用阿基米德螺旋线的螺杆状砂轮,在与工件的展成运动过程中产生渐开线齿形面。其主要差别,是机床的传动方式不同。NZA等类型的机床,分齿运动和差动运动是由交换齿轮控制的。而RZ300E则是采用了先进的电子技术,由光电编码器和电子装置控制磨齿过程的分齿运动和差动运动(其控制原理见方框图1)。这使机床的主传
The worm gear grinding machine RZ300E imported from REISHAUER company in our factory works like the NZA of the same type early products and adopts the screw-shaped grinding wheel of Archimedean spiral, Progression involute tooth surface during the development of movement. The main difference is that the transmission of the machine tool is different. NZA and other types of machine tools, sub-tooth movement and differential motion is controlled by the exchange gear. The RZ300E is the use of advanced electronic technology, optical encoder and electronic devices control the tooth grinding process of the tooth movement and differential motion (the control principle shown in Figure 1). This makes the machine master
