Definitions

  • This invention has prepared the way for other, considerably better and simplier solutions.
  • FIG. 1 is a hydraulic'motor, shown partly in section and provided with areduction gear according to the invention, t
  • FIG. 2 is agear ratio diagram
  • FIG. 3 is an effect diagram
  • FIG. 4 is a sketch used as basis for some formulas.
  • the reference numeral 1 designates a motor housing, in which is mounted an output shaft 2.
  • the shaft 2 In its inner end the shaft 2 is through splines 3 in engagement with the center of a nutating disc 4, this being in its outer collar shaped part provided with a gear ring 5.
  • the upper part of the disc 4 is provided with a ball shaped pin 6 which is located in a corresponding hole in the underside of an outer part of a distributing disc 7, mounted for rotation in the motor housing 1.
  • three of the pistons 8 are in connection with the inlet 10 for the hydraulic liquid, whereas the three other pistons 8 are in connection with the outlet 11 for the same liquid.
  • k piston speed, m/sek Motors within the scope of the present invention and having different data can be made in many different ways, e.g. through selecting the number of pistons, the piston area, the gear ratio by and so on.
  • the motor described above is reversible.
  • the device can be used as a pump.
  • the nutating disc 4 driven by the shaft 13 and the distributing disc 7 thereby force the six pistons 8 to bring about a reciprocating movement in their cylinders.
  • a rotary hydraulic device comprising a housing, a stationary gear ring in said housing, a rotatablenutating member in said housing, said member having a gear ring thereon in partial engagement with said stationary gear ring, an annular series of reciprocable pistons in said housing, said nutating member being in engagement with said pistons, means to supply hydraulic fluid to said pistons, said nutating member having a pin thereon concentric with said nutating gear ring, a shaft rotatable in said housing, and means connecting said pin for universal pivotal movement with said shaft at a point on said shaft spaced from the axis of rotation of said shaft.
  • a device as claimed in claim 1 and a second shaft coaxial with the first-mentioned shaft and rotatable in said housing, and means articulatedly interconnecting said nutating member and said second shaft for conjoint rotation while permitting nutating movement of number of teeth on said stationary gear ring.
