Definitions

  • the invention relates to a bellhousing according to the preamble of claim 1.
  • a bellhousing of the type mentioned above is known from German utility model 86 06 067.8.
  • the base body is provided in the end face adjacent to the flange body with a closed annular groove, into which a corresponding annular spring protrudes on the opposite end face of the flange body.
  • An elastomer material is arranged between the adjoining parts of the base body and the flange body, which provides noise and vibration damping.
  • a pump support which serves for the damped connection of a drive motor to a pump and consists of a base body supporting the motor and a cylindrical body supporting the pump. These two cylindrical components are inserted into each other coaxially. Between them there is a relatively large amount of elastomer material for power transmission. The components are specially designed and manufactured parts that are not manufactured in large numbers and cannot be used universally. The connection with the aid of the elastomer material is not made in the area of the end faces of the two load-bearing components.
  • the invention is therefore based on the object of creating a bellhousing of the type mentioned at the outset which allows the damped suspension of a pump with the aid of a base body which is present as standard.
  • the base body is designed in the region of the end face remote from the motor so that the groove can be machined in if necessary by machining.
  • This is not a continuous ring groove, but an opening in the wall sections, i.e. between remaining wall sections or ribs.
  • the depth or height of the groove is so great that there is an open opening in the wall sections, the remaining ribs ensuring that the rigidity of the base body is retained.
  • the projections then protrude into the openings in the wall sections, which can be designed depending on the forces that are to be transmitted and what other requirements are placed on them. The higher they are, the more space is available for radial support.
  • the protrusions are present where the openings are in the opposite base body.
  • openings and ribs are arranged at an angle.
  • the projections positively project into the openings and, after the elastomer material has been introduced, support the flange body radially on the base body.
  • the support is carried out equally in the direction of rotation (torque).
  • the tongue and groove connection is provided in the wall sections in the form of openings and projections which lie between the ribs. But it is also possible (claim 2) to provide the tongue and groove connection in the area of the ribs. Then it is not an open opening, but a corresponding groove, into which an equally short tongue protrudes. This groove is created practically when the openings are made by screwing in.
  • the invention enables the projections 8 to protrude "as far as possible" into the openings. There is no limit to the amount. In this way, correspondingly high radial loads can be introduced.
  • the bellhousing shown in the drawing consists of a base body 1 and a flange body 2. At the end faces on which the two bodies 1 and 2 adjoin one another, they are connected to one another by an elastomer material 3.
  • the base body 1 carries the motor, which is not shown, on its side remote from the flange body 2. On its free end face, the flange body carries the pump, which is also not shown.
  • the base body In the region of the end face of the base body 1, which adjoins the flange body 2, the base body has radially inwardly projecting ribs 4 of corresponding height or thickness, and between these ribs relatively flat wall sections 5 which connect the ribs to one another.
  • this relatively complicatedly designed base body 1 which is kept by default on the bearing, is to be used in a special case in order to fasten a pump in a damped manner, it is only necessary to screw a groove into the lower end face, which is in the area of the ribs 4 with 6 and Area of the wall sections 5 is designated 7. In the area of the wall sections 5, the depth is so great that an opening 7 is formed here, which is correspondingly open inwards.
  • a relatively simply designed flange body 2 which, where the openings are provided in the opposite end face of the base body 1, has projections 8 which are relatively high, ie in most cases higher than the wall sections thick , In the embodiment shown, the projections 8 are as high as the ribs 4 are thick.
  • projections 9 can also be provided in the area of the groove sections 6 in the ribs, but they are not as high. These projections 9 are surrounded by elastomer material 3 and provide additional support and power transmission.
  • a basic body that can be used for damped mounting can be produced in a simple and inexpensive manner from a basic body that can be efficiently produced in large numbers for the undamped mounting of pumps.
  • the ribs are designed as stiffening ribs 14 which are configured differently from the embodiment according to FIGS. 1 to 4.
  • the depth or height of the groove is so great that an open opening 7 is formed in the wall sections, but only one groove 6 in the area of the stiffening ribs 14, so that the rigidity of the base body is retained.
  • the invention can also be implemented without a groove 6 and a tongue (projection 9) being present in the area of the stiffening ribs 14.
  • the adjacent faces are smooth. Due to the way in which the openings 7 are produced, it is also sensible to also provide the closed groove 6, since this is produced by screwing in when the openings 7 are produced.
  • the projections 8 Due to the design of the projections 8 of any height, there is sufficient radial support of the flange body 2 on the base body 1, in particular under radial loading, so that the vulcanized elastomer material 3 between the wall of the base body 1 and the projections 8 is predominantly subjected to pressure and shear, whereby the extremely unfavorable, pure tensile stresses which are extremely unfavorable with rubber-like elastomers are largely avoided.
