设计简介
摘 要
线材生产中的飞剪机是用来切头、切尾、以及当出现事故时切取定尺的。飞剪机有许多类型，论文中的380双滚筒式碎断剪，是应用在高速线材生产中的一中。它采用单机驱动，通过齿轮和联轴器，带动传动轴，然后由输出轴上的剪刃切断轧件。本文做了以下工作：1.选择和确定了传动方案。2.选择并校核了电动机。3.设计了传动轴和齿轮，并校核了它们的强度。4.选择了与之配套的润滑系统和维修制度。
关键字：圆盘飞剪、单电动机传动、开式机架、最大剪切力、弯扭合成应力。

Abstract
Flying shear is used to cut head and end and design length as well as accident on wire rod producing. Flying shear has many kinds types. The 380 breaking shear designed in this paper is one of them. It adapts one electrical machine to drive.The electrical machine passes though gear and clutch, to drive the shafts and cut down the wire rod. The following work has been completed in this paper. One. Selecting and defining design scheme. Two. selecting and checking electrical machine. Three. Designing and checking principal shafts and gears. Four. Selecting suitable lubricate system and maintain scheme.
Key words: disk fly shear, single electromotor transmission, opening type machine rack, most cut power, crankle compound stress.
