| A main frame (24) includes an annular beam (30) by which the cutterhead is mounted onto an earth boring machine for a rotation about an axis of rotation. A plurality of radial spoke beams (28) extend generally vertically at the front of cutterhead and curve rearwardly to intersect with the annular beam (30). Each radial spoke (28) beam is constructed from a pair of spaced apart side plate members (42, 44) which define spaces between them for receiving a plurality of roller cutter mounts (38) therebetween. Roller cutters, including gauge cutters (36), can be installed and removed from their associated cutter mounts from the rear side of the cutterhead. A plurality of generally radially elongate cut-ground-material passageways (46) extend through the cutterhead in the regions between the radial spoke beams. A plurality of concentric, substantially circumferentially continuous face-support-ring members (48) are located forwardly of the cutterhead main frame but rearwardly of the peripheral cutting edges of the cutters in at least the radial region of cutterhead in which the cut-ground-material passageways are located. During rotation of the cutterhead, face-support-ring members (48) support fractured material against the face of the tunnel while the roller cutters (38) cut concentric kerfs with such material. | ||||||

| The main frame of the cutterhead (20) comprises a plurality of radial spoke beams (48) which are interconnected between a box-like hub structure (32) and an annular box beam (60) by which the cutterhead is mounted for rotation. Cutter mounting wells are defined by and between side wall portions (50, 52) of the radial spoke beams (48). The mined material passes rearwardly through the cutterhead via openings between adjacent radial spoke beams and open spaces in the cutter mounting wells. Cutter mounts (99) span laterally between the side wall portions (50, 52) and laterally brace the radial spoke beams (48) in addition to mounting the cutters (26). The radial spoke beams (48) curve rearwardly at their outer ends and connect to the annular box beam (60) at a location spaced enough rearwardly from the front portions of the spoke beams (48) such that an interior space (IS) is defined within the cutterhead. Roller type cutters (26) are installed onto and removed from the cutterhead frame from the rear side of the cutterhead. | ||||||

| A pressure-compensated cutter assembly for a tunnel boring machine includes a shaft, a cutter ring assembly rotatably mounted on the shaft, and first and second end retainers non-rotatably attached to the shaft. Rotary seal groups, immersed in lubricant, provide a moving seal between the rotating cutter ring assembly and the end retainers. A movable piston member is exposed to ambient pressures, and contacts the lubricant, such that increasing ambient pressure will increase the lubricant pressure, thereby keeping the pressure differential across the seal small. In one embodiment, the piston is a floating retainer portion. In another embodiment, the piston is an annular piston, and in another embodiment, the piston is a plurality of smaller pistons disposed in the first retainer. | ||||||

Die Erfindung betrifft einen Rollenmeißel für Tunnelvortriebsmaschinen. Die bekannten Ausführungsarten weisen einstückige Schneidringe auf, die daher immer komplett ausgewechselt werden müssen. Dies führt zu hohen Reparaturzeiten sowie einem materialtechnisch nicht vertretbaren Aufwand, da der Rollenmeißel dafür aus dem Bohrkopf ausgebaut werden muß. Die erfindungsgemäße Lösung ist, daß der Schneidring (1) aus mindestens zwei oder mehreren Segmenten (2) besteht. Dadurch ist es möglich, den Schneidring (1) selbst oder verschlissene Teile des Schneidringes (1) segmentweise zu erneuern, ohne die bisher nötige Demontage und Montage des kompletten Rollenmeißels aus dem Bohrkopf und den damit verbundenen Transportaufwand. Die gesamte Vortriebszeit wird so durch kürzere Reparaturzeiten minimiert. Die Segmente (2) des Schneidringes (1) sind dabei vorzugsweise mittels Profilführungen formschlüssig auf dem Rollengrundkörper lagebestimmt angeordnet und mittels schraubbarer Segmenthalterungen und/oder mittels Gewinderingen mit dem Rollengrundkörper verbunden. |

Die Einrichtung zur Befestigung von Disken in einem Schneidrad (2) für Tunnelvortriebsmaschinen umfaßt ein Schneidrad (2) mit Ausnehmungen (5), durch welche Lagerteile (3) gemeinsam mit den Disken hindurchgeschoben werden können. Die Befestigung der Lagerteile (3), welche einen gegenüber der Lagerachse (7) der Disken exzentrischen Umriß aufweisen, erfolgt in einer an die achsparallele Ausnehmung (5) anschließenden Ausnehmung (4), wobei je nach Drehlage der Lagerteile (3) eine unterschiedliche Position der Disken erzielt wird.

| La présente invention concerne la fraise (10; 10') d'une tête de forage, un moyeu constituant une partie de ladite fraise, ainsi qu'un procédé de fabrication d'un tel moyeu. La fraise (10; 10') est montée rotative dans un étrier, dans la tête de forage. Un roulement à rouleaux est placé entre l'arbre (11, 11') et le moyeu (18; 18') de la fraise. Pour que la résistance de portée des fraises soit améliorée, les voies de roulement extérieures (17; 17'a, 17'b) des rouleaux (15, 15'a, 15'b) du roulement à rouleaux font partie intégrante du moyeu. Selon le procédé de fabrication du moyeu (18; 18') les parties dudit moyeu qui ne doivent pas subir un traitement de durcissement sont laissées à l'état non fini ou recouvertes d'une couche empêchant la carburation. Le moyeu peut donc avoir des parties possédant différentes propriétés pour pouvoir satisfaire aux tolérances et aux spécifications. | ||||||
