Abstract (en)

[origin: WO2015158579A1] Cone or gyratory crusher with a crusher axle, the head of which is mounted in an upper axle bearing held by a crossbeam, wherein the upper axle bearing has a roll-off bushing accommodated in a central socket, wherein an annular abrasion insert is held in the roll-off bushing, and the head of the crusher axle rolls off against said abrasion insert, wherein the socket forms a conically tapering inner cone, and a pulling means is provided for drawing the roll-off bushing into the socket, and wherein the roll-off bushing becomes narrower when drawn in and thus frictionally clamps the abrasion insert in the roll-off bushing.
