文档介绍：摘要
从上世纪二十年代以来,蜗杆传动机构的研制工作发展很快,蜗杆传动已广泛应用在冶金、矿山、起重运输、化工。蜗杆传动是传递交错轴间的动力或运动的传动机构,它主要由蜗杆和蜗轮组成。蜗杆相当于一头或多头的等导程(或变导程)螺旋,蜗轮则是变态斜齿轮(或为斜齿轮或为直齿轮)。手摇蜗轮是蜗杆传动的一种,它是通过缠绕钢丝绳来调整带式输送机小车上改向滚筒的位置,从而防止输送带跑偏的一种装置。

Abstract
Since on century 20's, the worm anization development work development has been very quick, the worm drive has widely applied in the metallurgy, the mine, lifts heavy objects professions and so on transportation, chemical industry, national defense, has achieved the quite high technical worm drive is the transmission interlocks the power or the movement between the axis transmission system, it mainly posed by the worm bearing adjuster and the worm worm bearing adjuster is equal in either multi-head and so on leads (or changes leads) the screw, the worm gear is the abnormal helical gear (either for helical gear or for spur gear). The hand operated worm gear is the worm drive one kind, it is adjusts on the belt conveyer car through the winding steel wire to change to the drum position, thus prevented the conveyor belt runs the leaning one kind of equipment.
