摘要

A gyratory crusher frame part comprising: a topshell (209) mountable upon a bottom shell (102), the topshell having an annular wall (213) extending around a longitudinal axis (115) of the frame part; a spider (201) having a plurality of arms (203) extending radially outward from a cap (207) positioned at the longitudinal axis, each arm of the plurality of arms having a first portion (204) extending generally in a radially outward direction from the cap and a second portion (205) extending generally in an axial direction from an outer region of the first portion; an annular flange (202) positioned between the second portion of each arm and the annular wall, the flange having an outer circumferential perimeter (208) and an inner circumferential perimeter (224) relative to the longitudinal axis; the topshell comprising an outward facing surface (209) and an inward facing surface (214) relative to the longitudinal axis, the annular wall being defined between the outward and inward facing surfaces; wherein a section of the wall of the topshell neighbouring the flange comprises a concave section (402) at the outward facing surface and substantially a first half (400) of the concave section in the axial direction closest to the flange is a substantially uniform curve (403) extending continuously in the circumferential direction around the longitudinal axis.
