  • the invention further relates to a method for producing a swivel motor housing described above.
  • a swing-wing motor with a housing is known, which is produced for example from a forging blank. From the forging blank, an endkontumahe shape is first pre-milled. The final contour can be achieved by a multiple broaching process. Due to the machining in different fixtures, extensive intermediate burr removal operations are required. The high chip volume results in a high degree of tool wear in the milling and broaching tools.

  • the radially inwardly directed end region of the wing or the radially inwardly directed end regions of the vanes in the vicinity of the groove are likewise provided with a machining allowance.
  • a further preferred embodiment of the swivel motor housing is characterized in that the machining allowances, viewed in cross section and relative to a rotational axis of the swivel motor housing, are arranged symmetrically. Preferably, the areas with machining allowance and the areas without machining allowance are distributed so that there is a symmetry to the axis of rotation. This considerably simplifies subsequent machining.
  • Another preferred embodiment of the swivel motor housing is characterized in that the transitions between the areas are arranged with and without featuressaufbox at locations that are not relevant to function. This prevents critical burrs from occurring during machining.
  • the housing main body with the wing or the blades is pressed from sintered metal powder into a preform and subjected to a heat treatment; the sintered preform is forged to the swing motor housing with the machining allowances.

  • the wave with the wave-side wings is also called rotor. Between the housing-side wings 11, 12 and the shaft-side wings work spaces are formed, which may be larger or smaller depending on the position between the shaft-side wings and the housing-side wings 11, 12.

  • sinter forging offers the advantage of an extremely high compaction of up to 7.75 kilograms per cubic decimeter. This corresponds to about 99 percent of the density of solid steel. This high density and the fact that there is no open porosity in the near-surface area due to high densification even allows the use of laser or electron beam welding processes. With increasing density, the fatigue strength of the component increases exponentially. The low porosity also provides the advantage that without additional treatment required during operation pressure tightness of the swing motor housing 1 can be achieved.
  • sinter forging allows significantly more complex and finer geometries than with a conventional forged top.

  • the swivel motor housing 1 shown in FIGS. 1 and 2 is pressed from sintered metal powder into a preform or green body and then subjected to a heat treatment in a sintering furnace.
