Definitions

  • the invention relates to a compressor flange for connecting a screw compressor to a drive, having the features of the preamble of claim 1.
  • the invention also relates to a screw compressor having such a compressor flange.
  • Screw compressors currently available have connecting elements for connection to a drive, which are provided with a centering collar or centering pins for centering.
  • the connecting elements regularly include a connecting flange that can be connected to a front cover of the screw compressor.
  • the front cover closes and seals the compressor housing from the outside.
  • a refrigeration compressor with a horizontally flanged electric motor emerges, which in the closed version comprises a flange component for connecting the compressor to the electric motor.
  • the compressor housing has a hub-like projection for receiving the drive shaft and for receiving a centrally arranged projection of the flange component, so that the flange component is centered when it is inserted.
  • a further ring step which is concentric to the central projection, is intended to center the compressor in relation to the electric motor.
  • there is no mechanical shaft seal since a certain amount of leakage is accepted or desired.
  • a hole is provided in the flange component in order to supply lubricant from the electric motor to the interior of the compressor housing.
  • an adapter plate for connecting a compressor to a drive is also known.
  • the adapter plate rests against a shaft bearing and provides a seal that prevents air from entering the compressor through the shaft bearing.
  • the object of the present invention is to provide a compressor flange for connecting a screw compressor to a drive, which requires little manufacturing and assembly effort and combines several functions in one component.
  • the invention is characterized by the features of claim 1.
  • the seals form components of the connecting flange, so that the use of separate sealing means, which have to be installed separately from the flange component, is not necessary.
  • the compressor flange thus simultaneously assumes the function of a front cover, which is usually provided for closing and sealing a screw compressor. This means that the compressor flange also has a closing and sealing function in addition to the connection function. The number of components required can accordingly be reduced, with the result that the manufacturing and assembly costs are also reduced.
  • the axially and radially effective seals can be inserted in grooves on the compressor flange or molded or molded on.
  • the seal against the shaft preferably takes place in the region of the bearing of the shaft, so that the seal is not exposed to any dynamic loading. The seal thus has a long service life.
  • the compressor flange is pot-shaped and, in contact with the compressor housing and the housing of the drive, delimits a cavity for receiving a clutch, which connects the shaft of the compressor to a shaft of the drive.
  • the housing of the clutch by the compressor flange makes it possible to omit a clutch bell and thus use a simple clutch.
  • the number of components can be further reduced.
  • the space requirement is reduced due to the smaller overall size.
  • weight can also be saved.
  • a reduction in the number of components is also associated with reduced assembly costs, since fewer components have to be aligned with one another and fastened to one another. In addition, the places that have to be additionally sealed are reduced. This also reliably avoids the accumulation of manufacturing and/or assembly tolerances.
  • the seals provided on the compressor flange ensure that the clutch accommodated in the cavity of the pot-shaped compressor flange is adequately protected even if a clutch bell housing is omitted. This protection can also be guaranteed if, for example, the screw compressor is used in partially submerged operation. Furthermore, the cavity can serve to accommodate a lubricating medium, since the seals of the compressor flange ensure that no lubricating medium escapes to the outside. If there is a leakage of lubricant in the area of the shaft, the cavity of the cup-shaped compressor flange is used to catch the escaped lubricant.
  • the compressor flange has an axially effective seal for sealing against the housing of the drive. This also ensures a tight connection of the screw compressor to the housing of the drive.
  • annular step is preferably formed on at least one end face of the compressor flange for centering the compressor flange in relation to the compressor housing, the shaft, the bearing and/or the housing of the drive.
  • the compressor flange thus has a centering function at the same time and makes further connection elements, for example in the form of centering pins, superfluous.
  • An annular step for centering with respect to the compressor housing and the drive is preferably formed on each of the two end faces of the compressor flange.
  • an axial projection for the axial position fixing of the bearing is formed on the end face facing the compressor housing.
  • the axial projection can also be designed in such a way that it replaces an annular step arranged on the compressor side for centering.
  • the axial projection can be inserted into a recess formed on the compressor housing or the bearing in such a way that the axial projection is supported not only axially but also radially. In this way, the axial projection on the compressor flange fulfills a holding and centering function.
  • the flange can also have an annular step in the form that it accommodates the lateral surface of the shaft bearing and fixes its axial position. This also enables the flange to be centered on the bearing. The latter can be achieved in that the bearing end protrudes axially beyond the compressor housing or in that the compressor housing has a corresponding recess.
  • the compressor flange can preferably be fastened to the compressor housing by means of screws.
  • bores for receiving the screws are provided in the area of the first ring-shaped contact surface for contacting the compressor flange on the compressor housing.
  • the end face preferably forms the first annular bearing surface for the bearing of the compressor flange on the compressor housing in the region of the bottom of the pot-shaped compressor flange.
  • the cover function of the compressor flange can thus be implemented in a simple manner.
  • the central opening for receiving the shaft is also provided in the area of the bottom of the pot-shaped compressor flange.
  • the end face that radially delimits the cavity and is opposite the bottom of the cup-shaped compressor flange forms the second annular bearing surface for bearing of the compressor flange on the housing of the drive.
  • the compressor flange can also have openings, in particular maintenance and/or venting openings. These are preferably designed in such a way that the sealing function of the compressor flange remains guaranteed.
  • a screw compressor with a compressor flange serving both as a front cover for closing and sealing the compressor housing and as a connecting flange for connecting the compressor housing to the housing of the drive.
  • the space enclosed by the compressor flange can be designed as an open or closed compressor, depending on the requirements of the type of coupling used, the type of shaft connection or other requirements resulting from the application.
  • the only figure shows a section of a screw compressor 2 in the area of the connection to a drive 3 , the connection being effected via a compressor flange 1 .
  • the compressor flange 1 combines several functions in one component, since it not only establishes a connection between the compressor 2 and the drive 3, but at the same time centers the compressor 2 in relation to the drive via annular steps 14, 15 formed on its end faces 16, 17 3 allows.
  • the compressor flange 1 replaces an end cover for closing and sealing the housing 8 of the compressor 2 by an axially effective seal 11 being embedded in a first annular contact surface 7 for contacting the compressor flange 1 with the compressor housing 8 .
  • the compressor flange 1 seals against a shaft 5 of the compressor 2 , which is passed through a central opening 4 of the compressor flange 1 .
  • the radially effective seal 12 is in sealing contact with a bearing 6 which is provided for supporting the shaft 5 of the compressor 2 .
  • the sealing with respect to the shaft 5 of the compressor 2 thus takes place indirectly via the bearing 6. This has the advantage that the radially effective seal 12 is not exposed to any dynamic loading.
  • a further axially effective seal 13 is provided in the end face 17 for sealing the compressor flange 1 with respect to the housing 10 of the drive 3 .
  • the end face 17 also forms a second annular bearing surface 9 for bearing the compressor flange 1 on the housing 10 of the drive 3 .
  • screws 19 are provided, which are passed through bores in the end face 16 for screwing the compressor flange 1 to the compressor housing 8 .
  • the screws 19 ensure that the compressor flange 1 is axially prestressed relative to the compressor housing 8 , with the axially effective seal 11 also being pressed against the compressor housing 8 .
  • the annular step 14 in the area of the end face 16 is designed as an axial extension 18, by means of which the bearing 6 is held in position.
  • the compressor flange 1 thus also fulfills a holding function, with the bearing 6 being held by the connection by means of the screws 19 being ensured.
  • the axial shoulder 18 engages in a form-fitting manner in an annular recess of the compressor housing 8 .
  • the axial projection 18 also centers the compressor flange relative to the compressor housing 8 and/or the shaft 5 of the compressor 2 .
  • an axial receptacle 23 for the axial position fixing of the bearing 6 in the compressor flange can also be formed in the area of the end face 16.
  • the bearing 6 is advantageously designed in such a way that it protrudes in the axial direction, so that it can be at least partially inserted into the axial recess 23 (not shown).
  • the compressor flange 1 of the illustrated embodiment is also pot-shaped, so that a cavity 20 is formed between a base area, which is axially attached to the compressor housing 8, and a side wall area, which in this case is intended to accommodate a clutch 21 for connecting the shaft 5 of the compressor 2 with the shaft 22 of the drive 3 is used.
  • the compressor flange 1 thus also assumes a protective function, which makes the arrangement of a clutch bell unnecessary.
  • the seals 11, 13 ensure that the cavity 20 formed between the compressor 2 and the drive 3 is sealed off from the outside.
  • the compressor flange according to the invention shown in the figure is thus able to combine the functions of a front cover, a flange and a protective hood, while at the same time taking on a centering, holding and sealing function. All of these functions are implemented by a single component, so that the number of components required can be significantly reduced and the manufacturing and assembly costs can be significantly reduced. At the same time, the size and weight of a screw compressor are reduced so that it requires less installation space.
