摘要： The invention relates to a bit holder for an earth working machine, in particular a road milling machine, having a support member onto which an insertion projection is indirectly or directly attached on an insertion projection side, the support member comprising two first and/or two second stripping surfaces that are at an angle to one another, and the support member having a working side that comprises a bit receptacle. In order to achieve a stable and long-lived configuration for such a bit holder, provision is made according to the present invention that the first and/or second stripping surfaces diverge from the insertion projection side toward the working side.

摘要： A cutter bit includes a wear resistant element replaceably mounted to a front surface immediately below the cutting surface of the cutter bit. The body of the cutter bit is generally formed of a hardened steel, the cutting surface can be a diamond composition fixed in a step in the upper end of the cutter bit and the wear resistant element is preferably formed of a carbide composition or a sintered diamond composition. The wear resistant element can be coupled to a front end of a stem passing through an opening in the cutter bit immediately below the cutting surface.

摘要： The invention relates to a bit holder having an insertion projection and having a holding projection, the holding projection comprising a bit receptacle, and the holding projection protruding at least locally from or beyond the insertion projection in the tool feed direction. A bit holder of this kind is designed in service-life-optimized fashion by the fact that the holding projection comprises a supporting segment having a rigid, shaped-on supporting surface that is arranged at least locally in front of the insertion projection in the feed direction. The invention further relates to a base part for receiving an aforementioned bit holder.

摘要： A bit holder for a ploughing bit, particularly a bottom bit of a coal plough, includes an insert pocket 12 which is open at the top side 11 for receiving and supporting a bit stem of the ploughing bit and which pocket 12 is bounded on its edges by two lateral supporting walls 20, 30, a front supporting wall 13 and a rear supporting wall 14 with the rear supporting wall 14 projecting above the front supporting wall 13. In order to minimise the wear effect on the contact surfaces between bit stem and bit holder, the lateral supporting wall 20 facing away from the working face when the plough is in use projects above the front supporting wall 13 and the other lateral supporting wall 30 and forms an extended lateral support for the bit stem with respect to the other supporting wall 30.

摘要： A chisel holder changing system having a base element with a chisel holder receiver, into which a chisel holder equipped with a chisel can be inserted, wherein the chisel holder is inserted with a holder shaft into the chisel holder receivers and is maintained therein with the aid of bracing screws. Bracing screws can be screwed into a threaded receiver of the base element and during this are supported under tension in a bracing receiver of the holder shaft of the chisel holder. If in a chisel holder changing system in accordance with this invention the surfaces of the outer screw thread of the bracing screw and/or of the inner screw thread of the threaded receivers of the chisel holder receivers have a metallic layer of zinc and aluminum lamellas and a mineral chromium oxide bonding agent, which is burned in after the application, the screw connections are improved so that larger prestressing forces/tightening torques can be transmitted without damage to the screw connections.

摘要： An excavation cutting tool holder retention system. The cutting tool holder retention system includes a cutting tool holder having a holder engagement surface and a support block having a tool holder bore into which the cutting tool holder is inserted. A pin having a pin engagement surface is movably mounted to the support block such that the pin engagement surface may be moved to engage the holder engagement surface. At least one of the holder and pin engagement surfaces defines an inclined surface such that when the pin engagement surface is moved to engage the holder engagement surface, the shank portion of the cutting tool holder will be drawn into the tool holder bore. In the preferred embodiment, at least one of the cutting tool holder and tool holder bore is tapered such that the cutting tool holder will be drawn and wedged into the tool holder bore of the support block when the pin engagement surface is moved to engage the holder engagement surface.
