This invention concerns an axial thrust-bearing combination of a spindle shaft of a cone crusher comprising an intermediate disk 7 the upper face 8 of which is part concave. Against the upper face bears a convex surface on the lower end 10 of an upper shaft portion 2a of the spindle shaft. The bottom face 9 of the intermediate disk is also part concave against which bears a convex surface on the upper end 11 of the lower shaft portion 2b of the spindle shaft. The radius of curvature R1 of the upper concave surface of the intermediate disk is preferably less than the radius of curvature R2 of the lower concave surface of the intermediate disk. <IMAGE> |
