一般来说,阿基米德蜗杆蜗轮(ZA)相对是比较好生产的一种型号,原因如下:
• 加工工艺简单:阿基米德蜗杆在轴向平面上齿廓为直线,在车床上就可以通过简单的刀具切削加工来形成基本的齿形,对加工设备和工艺的要求相对较低。不像一些高精度、特殊齿形的蜗杆蜗轮,如平面二次包络蜗杆蜗轮等,需要五轴联动数控机床等先进设备和复杂的加工工艺。
• 刀具要求不高:生产阿基米德蜗杆蜗轮所使用的刀具结构和制造相对简单,成本也较低。普通的车刀、滚刀等刀具就能够满足其加工需求,不需要像加工某些特殊蜗杆蜗轮那样,需要定制特殊形状、高精度的刀具。
• 检测容易:阿基米德蜗杆蜗轮的齿形和尺寸检测相对容易,可采用常规的量具和检测方法,如卡尺、千分尺、齿厚卡尺等,就能对其主要尺寸和齿形参数进行测量和检验,不需要像一些高精度蜗杆蜗轮那样,依赖三坐标测量仪等精密检测设备。
Generally speaking, Archimedes worm gear (ZA) is a relatively easy-to-produce model for the following reasons:
• Simple processing technology: The tooth profile of Archimedes worm gear is a straight line on the axial plane, and the basic tooth shape can be formed by simple tool cutting on the lathe, and the requirements for processing equipment and technology are relatively low. Unlike some high-precision, special tooth shape worm gears, such as plane secondary enveloping worm gears, advanced equipment such as five-axis linkage CNC machine tools and complex processing technology are required.
• Low tool requirements: The tool structure and manufacturing used to produce Archimedes worm gears are relatively simple, and the cost is also low. Ordinary turning tools, hobs and other tools can meet its processing needs, and there is no need to customize special shapes and high-precision tools like processing some special worm gears.
• Easy to detect: The tooth shape and size of Archimedean worm and worm gear are relatively easy to detect. Conventional measuring tools and detection methods, such as calipers, micrometers, tooth thickness calipers, etc., can be used to measure and inspect their main dimensions and tooth shape parameters. There is no need to rely on precision detection equipment such as three-coordinate measuring machines like some high-precision worm and worm gears.
