Definitions

  • a first pressure groove completely concentrically encircling a first bearing eye and a second pressure groove a pitch circle surrounding a second bearing eye introduced.
  • the pressure grooves are then connected via a pressure medium connection with the high pressure of the gear machine in pressure medium connection.
  • Figure 2 is a side view of a simplified representation of a package of bearing bodies and gears of the gear machine of Figure 1;
  • FIG. 1 shows a longitudinal section of a designed as a gear machine 1 hydraulic working machine according to an embodiment is shown.
  • This has a machine housing 2, which is closed by means of two housing cover 4 and 6.
  • the right in Figure 1 housing cover 6 of the gear machine 1 is penetrated by a first bearing shaft 8, on softer a first gear 10 is disposed within the machine housing 2.
  • the first gear 10 is connected to a second gear 12 via a helical gear 14 into engagement, wherein the gear 12 is rotatably mounted on a second bearing shaft 16.
  • the first and second bearing shaft 8 and 16 are each guided in two plain bearings 18, 20 and 22, 24.
  • the right in Figure 1 sliding bearings 20, 24 are received in a bearing body 26 and the left in Figure 1 slide bearings 18, 22 in a bearing body 28.
  • an axial seal 46 is respectively introduced into the end faces 38 and 40 of the bearing bodies 26 and 28 for the separation of a high and a low pressure region of the gear machine 1.
  • a shaft sealing ring 48 seals the penetration of the first bearing shaft 8 through the housing cover 6 on the right in FIG.
