Definitions

  • the invention relates to a fluid-operated pivoting motor according to the preamble of claim 1.
  • a fluid operated swing motor having a winged motor shaft and a cylinder with axially extending ribs.
  • the wings and the ribs define together with end caps work spaces that are supplied arbitrarily with pressure medium and thereby generate a relative movement between the motor shaft and cylinder.
  • the torsional moment of the slewing motor include the wing or rib length and the radial extent of the wings or ribs and the average radius of the ribs or wings.
  • An engine-side increase in the torsional moment is possible if one of the enumerated parameters is increased. Additionally you can check the number of working chambers by an inevitable increasing number of wings and ribs, but with the disadvantage that the pivoting angle decreases.
  • An increase in the pressure of the pressure medium degrades the extrusion behavior and the durability of the standard lines and seals used in the ribs and wings.
  • the object of the present invention is to provide a swing motor concept that allows for a very large bandwidth with regard to the executable torsional moment.
  • At least one of the main assemblies cylinder or motor shaft has a base member and at least one adapter component for extending the working spaces.
  • the adapter components are used, wherein the end-side cover can be used independently of the length of the swivel motor so that standardized components can be used.
  • a cylinder made of a base member and adapter components can be much easier to produce, in particular to produce the ribs and the inner wall by a clearing process.
  • the smallest angular errors of the clearances have an immediate effect.
  • the tool costs increase extremely.
  • the basic component of the cylinder is designed at the end with a contact surface to a cover, wherein the adapter component of the cylinder for the basic component of the cylinder has a contour similar to the contact surface with the cover.
  • the contact surface of the base component to the cover and the adapter component is formed by a paragraph.
  • the basic component of the motor shaft is designed with a bearing seat surface for a pivot bearing in both lids, wherein the adapter component of the motor shaft for the base member of the motor shaft has a receptacle with a diameter as for the bearing seat surface of the second pivot bearing in the second cover. Also in the case of the motor shaft, similar to the cylinder, the effective length of the motor shaft can be increased by simply pushing on the adapter pieces.
  • a plurality of axially arranged in series disc seals are executed in the wings and ribs. This sectional arrangement of the disc seals facilitates the assembly enormous.
  • the effective length of an adapter component of the cylinder and / or the motor shaft is equal to the effective length of the basic component of the cylinder and / or the motor shaft designed so that you have to stockpile only a dimension of disc seals.
  • the welded connections between the covers and the base component and the at least one adapter component of the cylinder are designed radially on a lateral surface of the cylinder.
  • FIG. 1 The synopsis of Figures 1 and 2 describes a pivot motor 1, which has a cylinder 3, on the inner wall 5 axially extending ribs 7 are executed.
  • a motor shaft 9 is pivotally mounted, which has parallel to the ribs extending wings 11.
  • a disc seal 13 is arranged, which have identical dimensions.
  • the swivel motor is closed by a first cover 15 and a second cover 17, so that alternating work spaces 19; 21 are present, each via transverse openings 23; 25 are connected in pairs in the motor shaft.
  • the first cover 15 is in each case a pressure port 27; 29 ( Figure 2) for a pair of working rooms.
  • the cylinder 3 as a main assembly of the swing motor includes a base member 3G and at least one adapter member 3A.
  • the basic component 3G is used regardless of the number of adapter components 3A and determined with the distance between the inside of the lid 17 and the end of the rib a effective length L.
  • a shoulder 31 is formed so that axially extending contact surfaces on the one hand to cover 17 and the adapter component 3A present.
  • the adapter component 3A has the same outer diameter as the cover 17 in the area of the contact surface.
  • the adapter component 3A has the same contours as the basic component 3G to the cover 17, so that the adapter component 3A into the basic component 3G insert the cylinder and can provide an arbitrarily long arrangement of adapter components 3a.
  • the main assembly motor shaft comprises a base member 9G with the two transverse openings 23; 25, a bearing seat surface 33 for a first pivot bearing 35 and a mounting boss 37, z. B. for a stabilizer, not shown.
  • the basic component 9G of the motor shaft On a shoulder in the direction of the second cover 17, the basic component 9G of the motor shaft has a bearing seat surface 39 for a second pivot bearing 41. If, as in the illustrated embodiment, the motor shaft is extended by an adapter component 9A, the bearing seat surface 39 engages in a receptacle 43, the inner diameter of which is adapted to the diameter of the bearing seat surface 39 and constitutes a torsion-proof connection.
  • the effective length L of the adapter components 3A, 9A of the cylinder 3 and the motor shaft 9 are equal to the effective length L of the basic components 3G; 9G, so that the disc seals 13 can be installed in axial row arrangement.
  • the base member 3G, the adapter member 3A of the cylinder and the covers 15; 17 are each connected to each other by radially extending welds 45 on the lateral surface.
  • the same principle is used for the connection between the parts of the motor shaft.
