Definitions

  • the invention relates to an electrical machine with a first and a second housing part, at least two clamps being arranged distributed over the circumference of the electrical machine, according to the preamble of the independent claims.
  • a pump consisting of a motor and a pump head is shown.
  • the pump head and the motor are connected to one another by several clip connections.
  • Each clip connection is produced by the interaction of a locking clip, which is fastened to the motor via a clip flange, and a locking mechanism, which is located on the pump head.
  • the locking brackets and the notches are distributed around the pump.
  • the DE 10 2005 015 015 A1 , DE 32 20 448 C1 , DE 32 10 762 , DE 44 38 249 A1 , DE 646 962 and the DE 4118 628 A1 disclose pumps in which a first housing part is attached to a second housing part with a clamp US 6,764,284 B2 discloses a pump holder using a plumbing flange.
  • the electrical machine according to the invention is further characterized in that at least one holding area has at least one holding element and at least one clamp interacts with the holding element and that at least one clamp has at least one free end section and the at least one free end section comprises an engagement element, the engagement element with at least one holding element cooperates.
  • the electrical machine according to the invention has the advantage that simple assembly of the housing parts on one another is possible. It is also possible to rotate the housing parts relative to one another. Any angular position between the first and the second housing part is possible. There are no threads or screw openings. Complicated shapes such as detents or locking clips on the housing parts are also not required.
  • the assembly of the clamps is limited, for example, to attaching the clamp to the holding areas of the two housing parts.
  • the at least one holding element is designed as a receiving recess and that at least one clip engages in the receiving recess.
  • the holding element in the holding area enables a simplified assembly of the clamp for connecting the first and the second housing part.
  • the holding element offers the clamp a defined area in which the clamp acts on the respective housing part in the holding area. It also prevents the clip from falling off or slipping and thus preventing the connection between the first and second housing parts from being loosened.
  • the holding element also prevents the clamp from being released independently from the holding area.
  • the holding element is designed as a receiving recess, in particular as a groove.
  • the clamp engages in the receiving recess.
  • the receiving recess which is designed as a groove, for example, it can be precisely determined at which point the force of the Clamp acts on the housing part.
  • the housing can thus be adapted to the force.
  • the holding element can be designed as a radial projection. A radial projection prevents the clip from slipping off the housing part in the assembled state. Furthermore, the radial projection defines an area in which the clamp acts on the holding area of the housing part.
  • At least one holding element can extend essentially over an entire holding area, in particular the entire length of a holding area.
  • the holding element extends over 75% to 100%, in particular 85% to 100% of the holding area or the housing part. It is thus possible to attach the clamps to any part of the holding area.
  • the holding element in the holding area that runs around the housing enables an additional simplification of the assembly.
  • the first and the second housing part can be installed rotated with respect to one another essentially in any angular position in the circumferential direction, ie in particular rotated through 360 degrees with respect to one another. Continuous rotation is possible here, which means that the rotation does not just take place step by step.
  • At least one holding area of the first and / or second housing part is designed as a substantially circumferential flange.
  • a flange can, for example, be attached to housing parts at a later date.
  • the first housing part comprises a flange.
  • the flange is formed in one piece with the housing part.
  • the second housing part comprises a flange and the flange and the housing part are connected to one another in one piece.
  • both housing parts can comprise a flange which, in particular, is connected in one piece to the housing parts.
  • a one-piece design of the housing part and the flange simplifies the production of the electrical machine, since no subsequent attachment of a flange to one or both housing parts is necessary.
  • the flange can, for example, be cast directly with the housing part in one operation.
  • At least one clamp has at least one free end section and the at least one free end section comprises an engagement element.
  • the engagement element cooperates with at least one holding element.
  • the best possible hold on the holding elements can be achieved by designing engagement elements on the end sections.
  • the engagement elements of the clamps are adapted, for example, to the shape of the holding elements in order to achieve the best possible interaction.
  • the assembly of the clamps on the holding elements can be optimized by the engagement elements.
  • the end sections with the engagement elements are designed in such a way that they do not have any sharp edges, as a result of which damage to the holding element or one of the housing parts is avoided during assembly.
  • the engagement elements are designed as curves, for example. The round is a bend.
  • the clamps can also be removed more easily from the electrical machine by means of the engagement elements. This is advantageous when repairing the electrical machine.
  • At least one clip is designed as a spring clip, in particular made of metal, preferably steel.
  • the design of the clip as a spring clip enables the housing parts to be compressed by the spring force. Thus, for example, distances between the housing parts can be prevented. Distances between the housing parts lead, for example, to increased wear in the event of vibrations.
  • the formation of the clamp from metal also enables electrical contact to be made between the two housing parts.
  • the brackets enable equipotential bonding between the housing parts of the electrical machine. Further work steps, such as attaching a cable that is used for equipotential bonding, are no longer necessary.
  • At least one clip has a C-shaped basic shape.
  • the C-shaped basic shape has two free end sections.
  • the free end sections engage, in particular, expediently engage behind the holding areas of the housing parts by expanding the C-shape To achieve bias of the clamp, which ensures a secure fit of the housing parts.
  • a connecting element in particular a seal, preferably a wet seal, is arranged between the first and the second housing part.
  • a connecting element By arranging a connecting element between the first and the second housing part, a defined distance can be established. It can also be advantageous to insert a component with a material that differs from the housing parts between the first and the second housing part. This can be advantageous in particular if the material of the first housing part would react, in particular chemically react, with the material of the second housing part.
  • the connecting element holds the first and the second housing part together.
  • the connecting element can, for example, absorb additional forces that are applied to the clamp or the holding area in a less preferred direction.
  • the connecting element establishes the connection between the first and the second housing part, for example by gluing or increased surface friction.
  • the connecting element is designed as an adhesive layer or element with increased surface friction.
  • the connecting element can also produce a welded, soldered, heat-staked, pierced or vulcanized connection between the first housing part and the second housing part.
  • a force-fit or form-fit connection in particular by barbs that press into the material of the housing parts, or vice versa, lead to support for the clamp and the holding element when the two housing parts are held together.
  • the connecting element is a seal, in particular a wet seal.
  • the material of the wet seal is applied in a liquid state to the point where the seal will later be located.
  • the wet seal then hardens. Once the wet seal has hardened, it can be used as an ordinary seal.
  • a seal with the best possible sealing effect for the surface can be produced even with complex surfaces.
  • a wet seal enables a seal to be produced specifically for the area of application. The seal can therefore also be used in very complex and angled areas.
  • wet seal can also be designed to be adhesive.
  • the sealing effect is improved by connecting the housing parts via the seal.
  • the wet seal also has a connection or holding function. The use of a wet seal reduces the installation effort.
  • a connecting element is arranged between the first and the second housing part, the connecting element being part of a pole pot.
  • the pole pot separates the interior of the first housing part from the interior of the second housing part. The pole pot thus prevents the exchange of liquids and gases between the interior of the first and the interior of the second housing part.
