Definitions

  • the present invention relates to a machine of the Scroll type.
  • the invention applies to machines of the Scroll type functioning as a vacuum pump, but may also be suitable as liquid pump or as compressor.
  • the object of the invention is to produce a machine with a collected volume, the as small as possible, and with an absolute seal between the parties mechanical and fluid circuit.
  • EP 0 728 947 describes a machine of the Scroll type comprising on the one hand a fixed disk equipped with a spiral and on the other hand a mobile disk equipped with a spiral and animated with a circular translational movement and in which the seal between the fluid circuit and the drive parts mechanically is effected by a bellows bound at one end to a fixed part of the machine and at the other end to the moving disk undergoing the movement of circular translation.
  • the drive motor is located in end, which considerably lengthens the machine and also, the bellows sealing also supports torsional forces.
  • US 3,817,664 also discloses a machine of this kind with also a seal with a bellows also undergoing twisting efforts and again the drive system greatly lengthens the machine.
  • EP 0 428 729 describes a machine very more picked up: there is no output shaft driven by a motor, but this one is located inside the crankcase of the machine. In this machine, both discs, each equipped with a spiral, are driven in rotation. One, the motor disk is driven by the motor integrated in the housing and the other, which is off-center, is driven by an Oldham joint coupling maintains the relative angular orientation of the two discs. However, here, there is no sealing system between the circuit of fluid and mechanical drive.
  • Document DE 22 25 327 A describes a machine of the Scroll type comprising the features defined in the preamble of claim 1.
  • this machine drive means are located on the side.
  • the object of the present invention is to propose a very machine picked up, with an absolute seal between the mechanical parts and the circuit of fluid.
  • the subject of the invention is therefore a fluid displacement machine of the Scroll type having a fixed disk comprising a spiral work wall and a movable disc, also comprising a spiral work wall cooperating with that of the fixed disc, means for driving the disc movable in a circular translational movement, a sealed sealing bellows on the one hand at one of its ends to an organ related to the translational movement circular disk of the mobile disk and secondly, at its other end, to a part machine, said bellows separating the fluid circuit, parts mechanical drive of the mobile disk, the disk stationary is connected on the opposite side to the mobile disk to a fixed central shaft, comprising a discharge channel, said fixed central shaft being surrounded by said bellows, characterized in that the space between said bellows and said fixed central shaft constituting a conduit in that a hollow rotary main shaft surrounds said bellows and is carried by at least one bearing in a fixed frame, one end of said main shaft having an eccentric circular bore cooperating with an organ drive related to the mobile disk; said training means comprising an electric motor
  • a fluid displacement machine is seen Scroll type according to the invention.
  • Such a machine is particularly well adapted to operate as a vacuum pump, but can work as compressor or as fluid pump. It includes a fixed frame 1 in three parts assembled: a housing 1A, and a body in two parts 1B and 1C. AT this frame is fixed a manifold 2 equipped with a suction flange 3 and a flange of repression 4.
  • This frame encloses the whole of the machine and in particular its parts pumping stations located in the housing 1A and comprising a fixed disk 5 comprising a spiral wall 6 and a movable disk 7 also comprising a spiral wall 8 cooperating with that of the fixed disc.
  • a fixed disk 5 comprising a spiral wall 6
  • a movable disk 7 also comprising a spiral wall 8 cooperating with that of the fixed disc.
  • the fixed disk 5 is connected, on the opposite side to the mobile disk 7, to the frame 1 by a fixed central shaft 10 which, in the example described, is monoblock with the part 1C of the body of the frame 1.
  • This fixed central shaft 10 is hollow and contains a tubing 11 discharge ending in a discharge compartment 12 of the manifold 2 to which the discharge flange 4 is attached.
  • the mobile disk 7 is connected by its periphery, beyond its wall in 8 and around the fixed disc 5, at the periphery of a connecting flange 13.
  • This connecting flange 13, with the mobile disk 7, constitutes a sealed housing enclosing the fixed disk 5.
  • the central portion of the flange 13 is open and leaves pass the central fixed shaft 10.
  • This central part of the flange 13 is connected, or, as in the case of the figure, is integral with an eccentric hollow shaft 14 itself fixed so at one end of a sealing bellows 15 surrounding the central shaft fixed and the other end is fixed to the part 1C of the body of the frame 1.
  • the space 16 between the sealing bellows 15 and the fixed central shaft 10 constitutes a suction channel communicating with a suction compartment 17 of the manifold 2 to which is fixed the suction flange 3.
  • the eccentric hollow shaft 14 is journalled in a bore 18 made in a rotating main shaft 19 of axis 20.
  • the bore 18 has its axis 21 eccentric by relative to the axis of rotation of the rotary main shaft 19.
  • the rotation of the shaft rotating main 19 thus causes, associated with an anti-rotation means any, a translational movement circular, without rotation of the axis eccentric 14 and thus the connecting flange 13 and the mobile disc 7.
  • this anti-rotation is provided by a seal of Oldham 22, located between the connecting flange 13 and the part 1B of the body of the frame 1 which prevents any rotation of the mobile disc 7 and its connecting flange 13.
  • the rotary main shaft 19 is hollow and surrounds the sealing bellows 15. It is supported by bearings 23 and 24 respectively mounted in the part 1B and the part 1 C of the body of the frame 1.
  • the rotational drive of this main rotary shaft 19 is carried out by an electric motor whose rotor 25 is connected to the shaft 19 and whose stator 26 is connected to the frame 1.
  • a tubular sealing sleeve 27 separates the stator 26 from all moving parts.
  • the mobile disc 7, linked to the connecting flange 13 is positioned axially accurately by a pad system 28 rubbing between two lateral stops 29, 30.
  • the shoe 28 forms a circular ring, connected to the housing 7-13 (movable disk 7, connecting flange 13) and surrounding externally this housing and it rubs between the two fixed lateral abutments linked to the frame 1: the abutment 29 and a stop-shim 30.
  • the precise adjustment of the axial positioning of the disk 7 is made by the choice of the thickness of the stop-shim 30.
  • the pad 28 has holes 31 of oil passage.
  • Such a machine is thus perfectly suitable as a vacuum pump clean and dry.
  • FIG. 2 is a variant in which the rotary main shaft 19, contrary to Figure 1 is mounted cantilever on a single bearing 32, prestressed, with two rows of balls mounted in part 1B of the body of the frame. This simplifies the pump.
  • collector 2 has not been shown as well as the housing 1A, the discs 5, 7 and the axial positioning.
  • FIG. 3 is another variant in which, as in FIG. the rotary main shaft 19 is cantilevered on a single bearing 32; but in addition, the eccentric hollow shaft 14 is mounted in the eccentric bore 18 of axis 21 of the rotary main shaft 19 via a roller bearing with needles 33.
