摘　　要：密炼机是橡胶企业生产的重要设备,密炼机转子则是密炼机中最重要的零件,一旦其发生开裂失效,则整台密炼机都将无法工作.通过对密炼机转子进行受载分析、断裂处弯矩的计算、转子截面抗弯模量的确定、计算出转子的疲劳安全系数,由此从强度方面分析出转子的开裂原因.为设计制造及使用密炼机的厂家提供理论依据,从而避免密炼机转子开裂的再次发生.Banbury mixer is a important machinery in the rubber industry and its rotor is the most important element in the Banbury mixer. Once the axle of rotor cracks, the machinery will fall down. In this paper, we analyzed all kinds of loads acted on the axle, the bending moment at the crack, the modulus of bending at the cross section, and finally we got the factor of fatigue safety. Above this, we described the reason of the axle cracking. All this work can provide some theoretical foundations to the makers and users of Banbury mixer to avoid the cracking of the axle.

关 键 词：扭矩 弯矩 抗弯模量 安全系数 疲劳开裂
