摘　　要：螺旋机构在实际应用中,主要以传力、传导、调整为主,但应用的主要依据是以有无自锁为前提条件的,其自锁是由螺纹导程角和螺旋副当量摩擦角的大小关系来决定的,自锁与否又决定了螺旋机构的应用场所,在矿井提升机中可得到广泛的应用。螺旋副的传动效率同时受螺纹导程角和当量摩擦角的限制,同时又由于运动方向和负载方向的相同与否导至传动效率公式有所不同。Spiral mechananism in practical application,mainly in powertransmission, transmission, adjust the main. But their application is the main basis to have no self-lock is premise condition, the self-locking is composed of screw thread lead angle and equivalent friction angle relation decided, self-locking or not determines the screw mechanism application,in mine hoist can be applied widely. At the same time spiral mechanism in the design, according to its work is easy to produce the failure forms, we can from the wear resistance of screw thread strength, strength, etc, to carry out the design, checking.
