摘要： A hydraulic machine (1) is disclosed, with an annular gear (3) with internal teeth (6, 7) and, eccentrically mounted in the annular gear, a gearwheel (2) with external teeth (4, 5) which engage with the internal teeth, the external teeth comprising one more tooth than the internal teeth and the contour of the external teeth being formed by an envelope of a system of generating circles (14), the midpoints of which lie on a trochoid (9) which, as a rolling circle (10) rolls without slipping on a base circle (11), can be generated by the movement of a point lying on a radial ray of the rolling circle co-rotating with the rolling circle. A method of producing the contour of a gear wheel of such a machine is also disclosed. In such a machine it is desirable to realise a satisfactory inner seal and low Hertzian stresses. To that end, the spacing of the point from the midpoint of the rolling circle (10) is larger than the radius of the rolling circle (10). The tooth form can then be formed by the end points of a system of line segments which are located at right angles to the trochoid (9) and are the same length as the radii of the generating circles (14), wherein the trochoid (9) encloses a closed inner face and separates it from an outer face and several intermediate faces, and the line segments are arranged only in the inner face.

摘要： A method of machining, with a formed tool, a first rotor and a second rotor with mutually complementary meshing threads involves rotating a first workpiece about a longitudinal axis of the workpiece. The tool makes one or more passes along the longitudinal axis of the workpiece as the workpiece rotates so as to remove material, thereby forming the flanks of each helix of the first rotor's thread. The value of at least one of the parameters that collectively define the relative position and relative movement of the workpiece and formed tool is varied during each pass so as to vary the lead of the thread. The above steps are repeated for a second workpiece, thereby forming the second rotor. Adjustments are made to at least one of said parameters during one or more of the passes in order to maintain mutually complementary shapes of the threads of the rotors.

摘要： A method for hard fine machining of a workpiece with a worm-shaped cutting tool, wherein the workpiece has a profiling along its circumference. The cutting tool has a machining surface. A hard machining process of the profiling is carried out at simultaneous synchronized rotation of the workpiece around its axis and of the cutting tool around its axis with given meshing of the machining surface into the profiling by moving the cutting tool in the direction of the axis of the cutting tool. A shift movement is superposed to the cutting tool in the direction of the axis of the cutting tool during the hard machining. The shift movement includes at least one first section at which the cutting tool is moved in one of its axial directions and of at least one second section at which the cutting tool is moved in the other of its axial directions.

摘要： The multi-function machine tool of the present invention has a tool rest main body which is disposed movably relative to the main spindle of the machine tool in a first linear direction parallel to the axial line of the main spindle and a second linear direction perpendicular to the axial line of the main spindle, a turning tool rest 72 which is disposed so that this turning tool rest can turn relative to the tool rest main body about a turning axis 73 oriented in a direction that is perpendicular to the first and second linear directions, and control means which control the rotational motion of the main spindle, the turning motion of the turning tool rest about the turning axis, and the relative motion of the tool rest main body. Furthermore, the control means can cause the turning tool rest to perform a turning motion about an arbitrary position that differs from the position of the turning axis by concurrently and synchronously causing a turning motion of the turning tool rest about the turning axis, and a circular-arc motion based on the relative motion of the tool rest main body in the first linear direction and second linear direction.

摘要： A tool having only an end cutting-edge carries out a first movement of penetration into a screw blank so as to produce a groove having flanks substantially parallel to the pinion axis. The tool-holder is angularly displaced with respect to the spindle which carries the screw blank. A second movement of tool penetration takes place while the relative displacement is progressively reduced in order to obtain an inclined flank which produces a V-shaped profile. The screw is intended to form part of a compression and expansion machine and to cooperate with at least one pinion having V-form teeth.

摘要： A machine which may be used to either check or to machine the profile of an orbiting star gear for a gerotor type of fluid motor or pump is disclosed. The profile of a star gear is traced due to the interaction of a slide that carries a sensor, or a machining tool, in a back and forth direction toward and away from the star gear and in a second direction transverse to this back and forth direction with respect to a frame member. The slide is driven by an eccentric disc, at a rate which is determined in accordance with the number of teeth on the specific star gear in question. The combined motion of the star gear and the two slides causes the sensor, or the machining tool, to trace out the profile of the desired star gear for the purpose of either checking its profile, or of machining a new gear. A spring member is connected to the frame member to allow the frame member to move in a transverse direction but without rotation.
