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.

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.

Abstract: The present invention relates to a striking tool for crushing metal objects or stone materials, manufactured from an iron-based material and comprising a bearing section (3), into which a bearing opening (4) provided for the freely swinging mounting of the striking tool (1) on a metallic shaft is formed with an inner circumferential surface (7) surrounding the bearing opening (4), and comprising a striking section (2), which during use 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, comprising at least one metallic shaft, on which at least one formed striking tool (1) is mounted with its bearing opening (4), with there being metallic frictional contact between the outer circumferential surface of the shaft and the inner circumferential surface (7) of the bearing opening (4) of the striking tool (1).

Abstract: The present invention relates to a striking tool (1, 1?, 1?) for crushing metal objects or stone materials, wherein the striking tool (1, 1?, 1?) is manufactured from an iron-based material and comprises a bearing section (3, 3?, 3?), into which a bearing opening (4, 4?, 4?) is formed for the freely swinging mounting of the striking tool (1, 1?, 1?) around a pivot axis and comprises a striking section (2, 2?, 2?) which during use 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 objects or stone materials. The striking tool (1, 1?, 1?) improves with simple means the ability of its bearing section to absorb the dynamic loads acting on the striking tool during use. Moreover, the rotor according to the invention enables, using simple means, an optimally long useful life of the striking tools mounted on it in a swinging manner.

Abstract: A vibrator roller frame for supporting a vibrator roller on a horizontal axis of rotation and for transferring static and dynamic forces, comprises, a closed annular one-piece frame member, preferably made of cast steel, having side, end and corner parts, connected to the vibrator roller and annularly surrounding it. The side, end and corner parts are shaped in accordance with the static or dynamic forces they will receive. The corner parts have inside and outside relatively large radii of curvature and connect the side and end parts. The side and end parts have increasing width from a median axis toward the corner portions.
