摘要： The method for machining the helical grooves of an hour-glass screw for a compressor or expander of the screw and gate-rotor type, uses a tool (8) slidably mounted in a passageway (19) of a rotatable tool-holder shaft. The tool (8) will, during machining, move just like a tooth of the gate-rotor which will mesh with the screw in the future compressor. However, for progressive machining of the screw grooves, the tool (8) is progressively moved outwardly of the tool-holder form an almost fully retracted position in the tool-holder, towards the illustrated fully extended position, corresponding to the extent of a tooth of the gate-rotor. When the tool (8) engages the screw blank, the tool (8) is securely clamped by a piston (29). When the tool (8) is out of engagement with the blank (this happens during part of each revolution of the tool-holder), piston (29) is released and a gear (24), meshing with a rack (23) of the tool (8), is rotated for an incremental extension of tool (8). This allows a stable positioning of tool (8) during machining even if the extension of tool (8) out of passageway (19) reaches 45 % or more of the length of the tool.

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.
