摘要： The invention relates to the production of screw pump rotors comprising a pitch and/or depth of teeth which can be modified along the axis of the rotor. By means of a simple profiled machine tool (7), a first part of the profiled flank contour is clearly defined along the rotor axis (8) by means of its specific tool guide mechanism, and is then produced in a definitive manner. The remaining second part of the profiled flank contour is then determined according to the rolling movement of the pair of rotors according to the first part of the profiled flank contour carried out by the tool, by means of an approximation which is as precise as possible. It is thus possible to obtain transversally different profiled contours according to the pitch and/or depth of teeth which can be modified along the axis of the rotor. A disk milling cutter is selected to be used as a profiled machine tool.

摘要： A method and apparatus for making a globoid screw for use as a mainrotor in a compressor or expander wherein a cylindrical rotor body is mounted for rotation about the longitudinal axis thereof, a cutter having a plurality of teeth at spaced locations around a circumference disposed in a plane and having an axis of rotation disposed perpendicular to that plane is mounted for rotation about its axis and is disposed so that the plane thereof is parallel to the rotor body longitudinal axis and so that the cutter rotational axis is perpendicular to the rotor longitudinal axis, and the rotor body and the cutter are rotated at synchronized speeds. The rotor body and cutter are positioned relative to each other in a manner moving the cutter axis of rotation and the rotor body longitudinal axis relative to each other to decrease the distance between the axes during rotation of the cutter and rotor body so that the cutter teeth contact the rotor body curing each cutter rotation to remove material from the rotor body by a milling action to form a globoid screw profile including a groove having a pair of spaced-apart sidewalls and extending along the rotor body in a helical path. The relative speed between the rotor body and the cutter is changed by a given amount for a given time to effect a positional change between the cutter teeth and the material of the rotor body thereby resulting in a desired change in the globoid screw profile.

摘要： A broaching machine for broaching an outer surface of a rotor of a rotor assembly which includes a support shaft projecting from opposite end faces of the rotor for supporting the rotor rotatably about its axis. The machine includes a backing plate for backing the rotor assembly such that one of the end faces of the rotor is held in contact with backing plate. The circumferential position of the rotor assembly is established by a positioning pin which extends from the backing plate, and engages a hole formed in the rotor. The machine includes a first centering device which has a center engageable with one of opposite ends of the support shaft so as to hold and center the support shaft at the one end, and a second centering device having a V-block and a retainer block which are engageable with the other end of the support shaft so as to hold and center the support shaft at the other end. With the first and second centering devices, the rotor assembly is easily and accurately mounted on the machine, with the axis of rotation of the assembly aligned with a line of feed of a broach cutter.

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.

摘要： The rotors of a pair have intersecting axes. Their intermeshing teeth have tooth numbers differing by one and are deep enough to contact all around the rotor periphery. The entire tooth surfaces of one rotor are formed conjugate to the tooth ends of the other rotor. Said tooth ends have convex profiles in planes perpendicular to the tooth direction. The curvature centers of said profiles are displaced from the pitch surface towards the tooth bottom, so that the tooth addendum is algebraically smaller than the curvature radius of said end profile. Preferably said tooth ends are applied to the larger rotor of the pair, and may have a constant profile all along the tooth length.
