  • CONE CRUSHER, BEARING PLATE, AND KIT OF BEARING PLATES
    Publication number: 20140008475
    Abstract: A gyratory cone crusher includes a first and a second crushing shell defining a crushing gap. The first crushing shell is arranged to gyrate around a vertical axis, in order to crush material entering the crushing gap, and is vertically supported by a thrust bearing including first and second bearing plates defining a spherical sliding interface. One of the bearing plates has one or more cooling and/or lubricating grooves at the sliding interface, each groove defining a channel, extending from the center of the sliding interface to the periphery thereof. In order to obtain a uniform distribution of grooves, the cooling/lubricating grooves are in the form of one or more spirals extending from the center of the sliding interface to the periphery thereof. The disclosure further relates to a bearing plate and a kit of bearing plates involving such a bearing plate.

  • Screening mat for vibrating screen devices
    Patent number: 8622219
    Abstract: A screening media for use in vibrating screen devices that fractionize crushed stones or gravel. The screening media is made by extruding a fiber-reinforced rubber or polymeric material to form a strip in a length longer than that needed to make individual screening mats for use in the vibrating screen devices. Screening apertures are then punched in the strip, and the apertured strip is cut into individual mats. The extruded strip includes side portions configured to connect to support structures of the vibrating device. Prior to the cutting step, the apertured strip can be maintained in the form of a coil or a long-length element.

  • Tooth Milling Cutter and Method for Milling the Teeth of Toothed Gear Elements
    Publication number: 20130322974
    Abstract: Method for milling a series of teeth of a toothed gear element with teeth in a straight line with a milling cutter rotatable about a milling cutter axis and having at its periphery interchangeable cutting inserts arranged such that, when the milling cutter is brought to the toothed gear element, they reach into gaps between adjacent teeth or generate these gaps, and a corresponding milling cutter. Cutting edges of mounted cutting inserts extend radially and perpendicularly relative to the milling cutter axis. During milling of the tooth profile, the milling cutter axis is aligned in a plane perpendicular to the longitudinal extent of the tooth back and, during entering of the cutting inserts, rotated about the milling cutter axis, into the surface or gaps between the teeth, and pivoted in this plane over an angular range covering all normals to the profile surface of the tooth to be produced.

  • Bore Cutting Tool and Method of Making the Same
    Publication number: 20130302102
    Abstract: A bore cutting tool, particularly for cutting metal workpieces, includes a tool substrate and a tool coating on a surface of the tool substrate. The bore cutting tool comprises a plurality of pits in the surface of the tool substrate and wherein the tool coating extends over the pits such that the pit surface comprises the tool coating. In this way, the pit dimensions can be retained over prolonged tool life and the pits, with their coated surface, are particularly effective at retaining lubricant so that the thickness of a lubricant film can be increased as compared to a tool without the coated pits. In embodiments the pits are formed by laser etching and are present only on the cylindrical land. Average pit depth is suitably in the range 8 ?m to 25 ?m, average pit width and pit length is independently selected from 40 ?m to 250 ?m and average pit density is 20 to 30 pits/mm2.
