摘　　要：本文概述了目前国内外滚筒设计中截齿排列的优化原则，提出：为确保滚筒截割负荷波动系数最小，总截齿数减到最少，滚筒处于高效截割状态。截齿在圆周上均布应作为主要优化原则，其余原则应列入辅助原则。据此，对国内外广泛采用的棋盘式或混合式截齿排列的滚筒结构设计应用非均布叶片结构。并对棋盘式截齿排列滚筒的设计步骤与方法做了具体阐述。The paper summarizes the optimization principle of pick arrangernent in cutting drum designs.In order to make sure that fluctuation coefficient of drum cutting and sum of bits be minimum,and cutting drum be in high efficient stete,bits eqspacing on the drum cirle should be main optimization principle.The cutting drum structrue edsign,in which checkerboard or mixed bits range is widely used in the world,should adopt uneven vanes structure.The paper describes the desian step and method of checkerboard bits range cutting drum in detai
