Description

DK 172829 B1 ' iDK 172829 B1 'i

Opfindelsen angår en indretning ifølge Indledningen af krav 1.The invention relates to a device according to the preamble of claim 1.

Der kendes forskellige løsninger til anbringelse af strømningsmaskiner på deres montagested. Således vi-5 ser DE-A-2359591 en støbt vinkelfod bestående af to stort set U-formede elementer anbragt i en indbyrdes vinkel på 90*. Elementerne er fastgjort til en fundamentplade og til et mellemhus, som bærer en elektromotor. Fra GB-A-1057346 kendes en enkel vinkelfod, som 10 ved fastgørelse til pumpens sugeside forbinder huset med en fundamentplade. En indretning af førstnævnte art kendes fra US-A-1886035, hvor en fundamentplade har specielt udformede opstående holdere, der ved fastspænding til en endevæg på et passende udformet pumpehus 15 fastgør dette i en på pumpeakslen vinkelret plan.Various solutions are known for placing flow machines at their mounting location. Thus, DE-A-2359591 shows a molded angular foot consisting of two substantially U-shaped elements disposed at a mutual angle of 90 *. The elements are attached to a base plate and to an intermediate housing carrying an electric motor. GB-A-1057346 discloses a simple angular foot which, when attached to the suction side of the pump, connects the housing to a base plate. A device of the former type is known from US-A-1886035, in which a base plate has specially formed upright holders which, by clamping to an end wall of a suitably designed pump housing 15, attach it to a plane perpendicular to the pump shaft.

Fra DE-A-2905864 kendes en ganske anden type eftergivelig montering, hvor huset er indspændt i en slags stænger, der danner led ved forbindelsesstederne. Denne konstruktion tjener til udligning af spændin-20 ger frembragt ved varmeudvidelser og til opretholdelse af husets funktionsduelighed ved kraftige vibrationer.DE-A-2905864 discloses a completely different type of resilient mounting in which the housing is clamped in a kind of rods forming joints at the connection points. This construction serves to offset the stresses produced by heat expansions and to maintain the functionality of the housing by strong vibrations.

Opfindelsen har til opgave at anvise en prisbillig fastgørelsesindretning til strømningsmaskiner som med enkel udformning og enkel montagemulighed har en 25 høj grad af såvel mangesidighed som stivhed. Denne opgaves løsning fremgår af den kendetegnende del af krav 1.The object of the invention is to provide an inexpensive fastener for flow machines which with a simple design and simple mounting option have a high degree of versatility as well as rigidity. The solution of this problem is stated in the characterizing part of claim 1.

Med denne løsning står en fastgørelsesindretning til rådighed, som eksempelvis på enkel vis kan frem-30 stilles ved stansning. Overfor hinanden liggende flangeelementer er på kraftoptagende vis fastgjort til husets yderside, og fodstykker, der findes i området for disse flangeelementer, sørger for videreførelse af den optagne kraft. Et i et eller flere stykker udformet 35 bæreelement, der er forbundet med flangeelementerne og/eller fodstykkerne og samtidig også er forbundet 2 DK 172829 B1 r med husenden, giver en overordentlig stiv konstruktion.With this solution, a fastener is provided which can, for example, be easily manufactured by punching. Opposite flange elements are attached to the outside of the housing in a force-absorbing manner, and the footpieces located in the area of these flange elements provide continuity of the absorbed force. A carrier element, which is formed in one or more pieces, which is connected to the flange elements and / or the foot pieces and at the same time is also connected to the housing end, gives an extremely rigid construction.

De på huset indvirkende kræfter optages ikke blot gennem flangeelementerne og fodstykkerne, men også gennem et bæreelement, og de føres til fundamentpladen. Anven-5 delsen af et bæreelement, der strækker sig på tværs af husets længdeakse, og dets forbindelse med husenden, eksempelvis i området for flangefladen for en hustilslutning, har muliggjort optagelsen af navnlig på tværs af husets længdeakse virkende belastninger. Forskydnin-10 ger af akseltappen er derved begrænset til et minimum.The forces acting on the housing are absorbed not only through the flange elements and the foot pieces, but also through a support element and are passed to the foundation plate. The use of a support member extending across the longitudinal axis of the housing and its connection with the housing end, for example in the area of the flange surface of a housing connection, has enabled the absorption of stresses acting particularly across the longitudinal axis of the housing. Displacements of the shaft pin are thereby limited to a minimum.

ved en udførelsesform for opfindelsen positionerer centreringsorganer huset på bærerammen, ved hjælp af centreringsorganerne opnår man en stor forenkling af montagen, idet en opretning af bærerammen på huset er 15 unødvendig, og der efter anbringelsen af dette kun skal skrues på forbindelseselementerne, centreringsorganerne kan være centreringsstifter, -boringer, -flader eller lignende, der samvirker med modsvarende flader på strømningsmaskinens hus eller på den derpå anbragte le-20 jebærer, drivmotor eller lignende del. Dette muliggør eksempelvis ved serviceeftersyn på en indbygget strømningsmaskine en meget enkel og pålidelig montage af en lejebærer. Bærerammen danner dermed en bestanddel for referencepunkter eller referenceflader, i forhold til 25 hvilken strømningsmaskinen eller andre aggregatdele kan positioneres.In one embodiment of the invention, the centering means positions the housing on the support frame, by means of the centering means a great simplification of the mounting is achieved, the alignment of the support frame on the housing is unnecessary, and after the application thereof is only to be screwed onto the connecting elements, the centering means can be centering pins. , bores, surfaces or the like, which cooperate with corresponding surfaces on the housing of the flow machine or on the bearing carrier, drive motor or similar part arranged thereon. This enables, for example, service inspection of a built-in flow machine a very simple and reliable mounting of a bearing carrier. The support frame thus forms a component for reference points or reference surfaces, relative to which the flow machine or other assembly parts can be positioned.

ved en yderligere udførelsesform ligger centreringsorganer på husenden og/eller på en med husenden forbundet komponent an mod anlægsflader på bæreelemen-30 tet. Således kan eksempelvis en på husenden anbragt le-jebærer eller tætnende flange være forsynet med centreringsstifter, der rager ind i tilsvarende centreringshuller i bæreelementet. Ved montagen er det tilstrækkeligt med en enkel indskubning for at sikre en nøjagtig 35 fiksering af bærerammen.In a further embodiment, centering means lie on the housing end and / or on a component connected to the housing end against abutment surfaces of the support member. Thus, for example, a bearing or sealing flange disposed on the housing end may be provided with centering pins projecting into corresponding centering holes in the support member. When mounting, a simple push-in is sufficient to ensure an accurate fixation of the support frame.

Ifølge en anden udførelsesform for opfindelsen er bæreelementet forsynet med åbninger til optagelse af 3 DK 172829 B1 fastgørelsesorganer. Såfremt husenden er udformet med en flange og eksempelvis lukkes ved hjælp af et husdæksel eller et tilsluttet blokaggregat, så kan bærerammen ved hjælp af bæreelementet og de deri udformede åbnin-5 ger på enkel vis fastgøres til huset gennem de fastgørelsesorganer, der holder hustilslutningen.According to another embodiment of the invention, the carrier is provided with apertures for accommodating fasteners. If the housing end is formed with a flange and, for example, is closed by means of a housing cover or a connected block assembly, the support frame and the openings formed therein can be easily attached to the housing through the fastening means holding the housing connection.

Ifølge endnu en yderligere udførelsesform for opfindelsen er flangeelementerne og fodstykkerne udformet i ét stykke, og de er forbundet med et eller flere 10 bæreelementer. I modsætning til en konstruktion i et stykke, hvorved eksempelvis bærerammens facon udstanses af en plade og gives sin form ved bukning, udmærker denne udførelsesform sig ved en større alsidighed. Herved kan de på begge sider af husets længdeakse anbragte 15 flangeelementer og fodstykker hver være udformet i ét stykke og være forbundet med et bæreelement gennem lasker eller lignende. På fordelagtig måde egner punktsvejsning sig til forbindelse af de enkelte dele. For huse med forskellig yderdiameter, men med normerede be-20 fæstigelsesboringer for anbringelsen på et fundament, kan flangeelementerne og fodstykkerne også være to-delte. Dermed kan der gennem en enkel kombination af præfabrikerede fodstykker med forskellige i anlæg mod huset liggende flangeflader opnås en tilpasning til for-25 skellige husstørrelser i en byggeserie. Endvidere kan det flangeelement, der ligger an mod huset, være udformet i ét stykke med bæreelementet, og det fodstykke, der sikrer forbindelsen med bundpladen, kan være en selvstændig komponent.According to yet another embodiment of the invention, the flange elements and the footpieces are integrally formed and are connected to one or more supporting elements. In contrast to a one-piece construction in which, for example, the shape of the support frame is punched by a plate and given its shape by bending, this embodiment is distinguished by a greater versatility. Hereby, on both sides of the longitudinal axis of the housing, the 15 flange elements and footings may each be formed in one piece and may be connected to a support element through lugs or the like. Advantageously, spot welding is suitable for connecting the individual parts. For houses with different outer diameters but with standard mounting bores for mounting on a foundation, the flange elements and footings may also be two-part. Thus, through a simple combination of prefabricated footings with different flanges facing the house, an adaptation can be made to different house sizes in a building series. Further, the flange member abutting the housing may be integrally formed with the support member, and the foot piece securing the connection to the base plate may be an independent component.

30 En yderligere udførelsesform er ejendommelig ved et bæreelement, som er i flere stykker og er kraft-og/eller formsluttende forbundet med en husende, ved et stift hus kan en husflange dermed gøres til en bestanddel af en bærer, idet det bæreelement, der er anbragt 35 på flangeelementet og/eller fodstykkerne, danner en forbindelse med huset. Forbindelsen mellem indbyrdes 4 DK 172829 B1 modstående fodstykker, såvel som et derimellem liggende flangeafsnit af husenden, udgør således bæreelementet.A further embodiment is characterized by a multi-piece carrier and is connected to a housing by force and / or shape, so that, in a rigid housing, a housing flange can be made into a component of a carrier, the supporting element being arranged 35 on the flange element and / or the footings, forms a connection with the housing. Thus, the connection between mutually opposing footings, as well as an intermediate flange portion of the housing end, constitutes the supporting element.

Med henblik herpå kan der på enkeltdelene anbringes vinkelformede tunger, der kan give en fastgørelse.To this end, angular tongues may be placed on the individual parts which may provide a fastening.
