The present invention relates to a cutter (10) for a boring head, preferably a boring head for shaft drilling, wherein the cutter (10) is rotatably mounted, via a shaft (12) of the cutter (10), in a saddle secured to the boring head. Bearings (18, 20) are provided between the shaft (12) and an outer roller body (16) of the cutter (10) to make it possible for the roller body (16) to rotate relative to the shaft (12). Seals (33) are disposed between the shaft (12) and the roller body (16) and channels/bores (38, 48, 50, 66) are provided to introduce lubrication internally into the cutter (10). The shaft (12) has a center axis (14). The invention is characterized in that a device (70) for positioning of spacer means (42, 44), a lubrication channel (66) and a diaphragm (60) are provided in the shaft (12), substantially concentrically with the center axis (14), said device, channel and reservoir being provided to accommodate lubrication. The invention further relates to a method for filling a lubrication system. |
