It takes the middle part by the steel loop, the affiliation changes the host, the driven cone pulleys working radius to realize the stepless change, rotates the handwheel, through the gear, the rack and the tension bar causes the transportable awl crop rotation end motion, changes the host, the driven cone pulley and the steel loop working radius, thus realizes the speed change. Moreover, its structure is simple, the manufacture is convenient. It mainly uses in the metal-cutting machine tool, the textile machinery and so on high speed machine.Key words: Steel loop, cone pulley, limitless speed change, gear, axi
