Definitions

  • the invention relates to a low-noise hydraulic unit with a hydraulic pump driven by an electric motor, which are held on and driven by the electric motor and with a motor bracket held on a base plate.
  • Such a hydraulic unit is from the magazine "Technische Rundschau", 2001, No. 6, pages 34 and 35, in particular Figure 2 and the associated description, known.
  • the reservoir forms thereby three side walls of a cuboid frame, the Bottom is formed by a base plate.
  • the motor-pump group is arranged horizontally.
  • the engine is on one Engine bracket attached to the via damping elements Base plate of the frame is held. This constructive Design of the hydraulic unit enables a very good noise reduction.
  • the open sides of the cuboid Frames can be closed with insulation walls.
  • the horizontal Arrangement of the motor-pump group required for that Installation of the hydraulic unit with a large footprint, that in many applications, especially in machine tools, is not available.
  • the invention is based, a low-noise task Hydraulic unit to create that only a small footprint for his lineup needed without being effective Noise reduction must be dispensed with.
  • Figures 1 and 2 show a hydraulic unit with a cuboid frame 10.
  • a reservoir 12 for hydraulic Pressure medium welded on a base plate 11, the after closed at the bottom is a reservoir 12 for hydraulic Pressure medium welded.
  • the reservoir 12 is composed of individual vertically arranged sheets, which are welded together in such a way that the storage container 12 has a U-shaped cross section.
  • the reservoir 12 forms three side walls 13, 14, 15 of the cuboid Frame 10.
  • the ceiling 17 and the fourth side wall 18, the position of which is shown in broken lines in FIG. 2, are preferably designed as insulating walls that can be detached in the frame 10 are used. After removing the insulation walls 17 and 18 are the individual components of the hydraulic unit easily accessible.
  • the motor-pump group 21 is made up of one Electric motor 21m and a hydraulic pump 21p formed.
  • the motor-pump group 22 is composed of an electric motor 22m and a hydraulic pump 22p formed.
  • the hydraulic pumps 21p and 22p are on the corresponding electric motors 21m or 22m and are driven by them.
  • the housing of the electric motors 21m and 22m are on a motor mount kept as a table with a rectangular top 25 and four legs 26 to 29 is formed. Plate 25 is arranged parallel to the base plate 11. The legs 26 to 29 are welded to the corners of the plate 25.
  • damping means between the plate 25 and the legs 26 are in the figure 1 arranged only schematically illustrated damping elements, of which only the damping elements 32 in FIG. 1 and 33 are visible.
  • the damping means between the plate 25 and the legs 26 to arrange 29, the legs 26 and 29 with the base plate 11 are welded.
  • the plate 25 has two recesses 35 and 36 provided. Through these recesses are the hydraulic pumps 21p and 22p guided from above.
  • the associated Electric motors 21m and 22m are located above the plate 25, their housing - as already stated above - mechanically are held on the plate 25.
  • Hydraulic unit contributes to the motor-pump groups 21 and 22 in the interior of the cuboid frame 10 are arranged. It also contributes to the good noise reduction at that of the plate 25 on which the motor-pump groups 21 and 22 are held, and the legs 25 to 29 formed table, only on the damping elements 32, 33 the base plate 11 - but not on the side walls of the storage container 12 - is held.
  • FIG. 1 and 2 is an exemplary embodiment Hydraulic unit with two motor-pump groups 21 and 22 shown.
  • the invention can be carried out in the same way as a hydraulic unit with only one motor-pump group or also as a hydraulic unit with more than two motor-pump groups realize.
