  • Patent number: 11517909
    Abstract: A striking tool for crushing metal objects or stone materials, manufactured from an iron-based material and including a bearing section, into which a bearing opening provided for the freely swinging mounting of the striking tool on a metallic shaft is formed with an inner circumferential surface surrounding the bearing opening, and including a striking section, which is exposed to a striking load by contact with the material to be crushed, and a rotor for a machine for crushing metal objects or stone materials, including at least one metallic shaft, on which at least one formed striking tool is mounted with its bearing opening, with there being metallic frictional contact between the outer circumferential surface of the shaft and the inner circumferential surface of the bearing opening of the striking tool. The striking tool allows, the danger of excess wear in the region of its bearing opening to be minimized.

  • Patent number: 11198131
    Abstract: A striking tool for crushing metal or stone materials, where the striking tool is manufactured from an iron-based material and includes a bearing section, into which a bearing opening is formed around a pivot axis and includes a striking section which is exposed to a striking load by contact with the material to be crushed, and a rotor equipped therewith for a machine to crush metal or stone materials. The striking tool improves with the ability of its bearing section to absorb the dynamic loads acting on the striking tool. The bearing opening has a support section, on whose inner circumferential surface the striking tool is mounted for its swing movement around the pivot axis and has an extension section, which is connected to the support section and the bearing opening is extended in the direction of the striking section with respect to the support section.
