    摘要： A rotating cutting tool to cut asymmetrical teeth in a gearwheel in which each tooth (21) has an active flank (A) with a convex profile meshing with the profile of a tooth of an opposing gearwheel meshing with the gearwheel and a secondary concave flank (S), provided with teeth (11) on a generally helical path which extends from one side to the other with respect to a median cross-section (M-M) of the tool which is intended to be intersected by the radius Rp of the gearwheel which is at right angles to the axis of rotation of the tool working on the gearwheel to cut its teeth. The helical teeth have a first flank (CA) which is intended to cut the said active flank (A) of the gearwheel teeth and a second flank (CS) intended to cut the secondary flank (S), the pitch (P1) between the first flank (CA) of the helical teeth being constant and the pitch (P2) of the second flank of the teeth being smaller than the pitch (P1).

    摘要： Disclosed is a method for manufacturing a stator for an eccentric screw motor where at least two milling heads are used for machining the inner wall of the stator tube, wherein, at the start of the machining, one of the milling heads is brought to a predetermined position near the stator with respect to the end of the stator tube, the milling head is fed into the tube interior along its linear axis from this predetermined position, and a thread is machined until the milling head reaches at least the longitudinal center of the stator tube or exceeds a predetermined value, and the second milling head starts its machining of the inner wall surface of the stator tube at this point, wherein the milling head is moved along its linear axis and rotated about its rotary axis until the milling head reaches the centre of the stator tube.

    摘要： A milling process to produce profiles on rod-like workpieces at a high rate of cutting. The profiles are produced in cutting segments.An apparatus is provided wherein the cutting edges are mounted on a milling head. The milling head rotates about its own axis and performs a relative circulating movement about the axis of the workpiece as well as a relative linear feed movement. The rotational and circulating movements are coordinated with one another in such a way that in accordance with their different radial positions and different cutting edge shapes the individual cutting edges form the profile on segmental portions of the contour while successively moving into the profile plane of the workpiece.

    摘要： Screw rotors for a screw compressor or expander incorporating improved screw profiles on both male and female rotors wherein certain mating portions of the two rotor screws have involute profiles to provide conjugate action of these screw portions with minimum sliding motion of such mating portions and with the remaining non-involute screw portions having generally circular arc profiles so that gear cutting and measuring techniques can be used in the production of such screw rotors.

    摘要： A rotary cutting tool for forming fluted rotors and the like comprising a cylindrical body having a plurality of metallic carbide cutting blades which are detachably mounted on the circumference of the body. The blades are arranged along a helical line with respect to the axis of rotation of the cutter body. The blades may be circumferentially spaced apart equidistant, one blade from each adjacent blade, to form only one turn of the helix and whereby each blade may be easily ground to a precise cutting edge contour while mounted on the cutter body. The cutting edge contour of each blade may be such that each blade cuts portions along the entire profile of the form produced on the workpiece.
