Abstract: Described is a method for assembling a gyratory crusher (1) where a main shaft arrangement (2) having a main shaft (3) with a midmost axial portion enclosed by a first crushing surface (4) is lowered axially from a free-hanging position down into a centrally positioned bushing (5) which provides guidance and support for the main shaft (3) where at least a portion of the bushing (5) is located below the first crushing surface (4) which is configured for interaction with an opposite second crushing surface (6). The method is characterized in that the method comprises the steps of mounting guiding means (7) on the main shaft arrangement (2) prior to guiding the main shaft (3) into the bushing (5) where the guiding means (7) protrude radially in relation to the centre axis of the main shaft (3) to such an extent that the guiding means (7) are visible when viewed from an axial top position over the main shaft arrangement (2), and having an operator with a view from the axial top position to lower the main shaft (3) down into the bushing (5) while observing the relationship between the second wear surface (6) and the guiding means (7).

Abstract translation: 描述了一种组装旋转式破碎机（1）的方法，其中具有主轴（3）的主轴装置（2）具有由第一破碎表面（4）包围的中间轴向部分从自由悬挂位置轴向降低 下降到中心定位的衬套（5）中，其为主轴（3）提供引导和支撑，其中衬套（5）的至少一部分位于第一破碎表面（4）的下方，其被配置为与相反的 第二破碎表面（6）。 该方法的特征在于，该方法包括以下步骤：在将主轴（3）引导到导向装置（7）径向伸出的衬套（5）中之前，将导向装置（7）安装在主轴装置（2）上 相对于主轴（3）的中心轴线的距离，使得当从主轴装置（2）上的轴向顶部位置观察时，引导装置（7）可见，并且具有从 轴向顶部位置，以在观察第二磨损表面（6）和引导装置（7）之间的关系的同时将主轴（3）向下降入衬套（5）。
