单轴破碎机主要由主轴、定刀、承载箱体、箱体支架、液压推料系统和驱动装置等组成,用于破碎木材、橡胶、塑料和纸等废旧物料~([1-2])。单轴破碎机工作环境恶劣,破碎废弃物料时会产生大量的碎屑和粉尘,进入轴承后会对其造成破坏,导致机器故障。当前,大部分破碎机主轴密封方式主要采用简 The uniaxial crusher is mainly composed of the main shaft, the fixed knife, the bearing box, the bracket of the box, the hydraulic pushing system and the driving device. It is used to crush the waste materials such as wood, rubber, plastic and paper ~ ([1-2] . Uncoaxial crusher bad working environment, crushing waste materials will produce a lot of debris and dust, into the bearings will cause damage to them, leading to machine failure. At present, most of the crusher spindle sealing method is mainly used Jane
