蜗杆、蜗轮这两个元件组成了蜗杆传动的最基本单元。由于蜗杆传动有传动平稳、能自锁、降速比大和分度精度高等优点,在机械制造业中,尤其在机床制造业中得到广泛应用。它几乎成为一般低速转动工作台和连续分度机构的唯一传动形式,冶金工业中轧机压下机构,煤矿设备中的各种绞车和采煤机组的牵引装置,起重运输行业等也都广泛采用蜗杆传动。此外,精密仪器设备和军工、宇宙观测部门常用的分度、操纵、计算、测距机构、雷达装置、大型天文望远镜等也都离不开蜗杆传动。
Worm, worm gear these two components constitute the worm drive the most basic unit. As the worm drive has a smooth transmission, can be self-locking, high speed ratio and indexing accuracy, etc., in the machinery manufacturing industry, especially in machine tool manufacturing industry has been widely used. It has almost become the only common form of low-speed rotary table and continuous indexing mechanism, rolling mill pressing mechanism in metallurgical industry, various winches in coal mining equipment, traction devices for coal-mining units, lifting and transportation industries, etc. are also widely used Worm drive. In addition, precision instruments and equipment and military, universe observation division commonly used indexing, manipulation, computing, ranging institutions, radar installations, large astronomical telescopes are also inseparable from the worm drive.
