本文讨论了不同蜗杆副的轮齿成形,并引伸出了如何选择更有效的方法来得到高精度蜗杆传动的问题。结论是:以蜗轮为基础件的单包络蜗轮副比以蜗杆为基础件的传统圆柱蜗杆副要优越得多。采用平面齿蜗轮作为单头蜗杆传动的产形件,采用渐开线斜齿轮作为多头蜗杆传动的产形件,前者也称为威特哈勃蜗杆传动。本文报导了应用包络蜗杆传动成功地达到相当于DIN 1～2级的高精度。 This article discusses the gear forming of different worm pairs and leads to the question of how to choose a more efficient way to get a high-precision worm drive. The conclusion is that the single enveloping worm gear based on the worm gear is much superior to the traditional worm helical gear based on the worm gear. The use of flat-tooth worm gear as a single-headed worm drive-shaped parts, the use of involute helical gears as the production of long worm gear, the former also known as the Witt Hubble worm drive. This article reports the successful application of Enveloping Worm Drive to a high level of accuracy equivalent to DIN level 1 to 2.
