Es zeigens Pig. 1 die Vorrichtung Im Längeschnitt und Fig. 2 bin 4 je eine Vaiiante der in Ptg, 1 dargeatellten Gelenk#verbindung zwisel;en Motorwelle und Antriebewolle in vergrößertem Maßstab-Die Antriebevorrichtung weist einen elektrischen Antriebsmotor 11 und ein mit dem Motor zu einer Baueinbeit vereinigten Sel)nock-enge-. triebe 12 auf. Der Motor 11 hat ein zylindrischeo Geh**uj3(,. 13, das auf der einen Seite von einem Lagerdeckel 14 und auf der andr;ren Seite von einem Plansch 15 des, Getriebegeblusea nach außen hJn vorachlossen ist.- Das Gehäuse 13 trägt innen zweJ in der Zeichnune, nicht näher dargentellte Magnetpolkörper, zwischen Clenen der Anker 16 deu Iaotorp angeordnet int# Der Anker 16 sitzt zusaximten mit einem Strom.viender V1 auf der Motorwelle 18, die in einer liagerl)ueliao 19 im Lagerdeckel 14 und einer Lagerbuchue 20 e Plansch 15 drohbar gelagert Ist. Der Lagerdecke3 14 und das Getriebegehhuse sind über Zuganker 21, 22 am Gehätise 13 fentgespannt. Zwischen dem litIgerdeckel 14 und dem Gehäuse 13 ist eIne Tragplatte 23 für die S.chleifbüroten 24 den Stromwendern 17 eingespannt. There Pointing Pig. 1 the device in longitudinal section and Fig. 2 bin 4 each a variant of the articulated connection shown in Ptg, 1 between the motor shaft and drive shaft on an enlarged scale - the drive device has an electric drive motor 11 and a unit combined with the motor to form one component ) nock-narrow. raise 12. The motor 11 has a cylindrical housing 13, which is pre-locked outwards on one side by a bearing cover 14 and on the other side by a flange 15 of the gear unit. The housing 13 carries on the inside Two magnetic pole bodies in the drawing, not shown in detail, between the armature 16 are arranged int # The armature 16 sits together with a Strom.viender V1 on the motor shaft 18, which is in a liagerl) ueliao 19 in the bearing cover 14 and a bearing book 20 e Plansch 15 is stored threateningly. The bearing cover 14 and the gear housing are tensioned on the housing 13 via tie rods 21, 22. Between the litIgerdeckel 14 and the housing 13 a support plate 23 for the grinding office 24 the commutators 17 is clamped.
Das Schheckengetriebe 12 weist eine gleichacheig zur Motorwelle
18
angeordnete und mit dieser drehfeBt gekuppelte Antriebewelle
26 auf, die einerseits in einer fest im Getriebegehäupe sitzenden Lagerbuchse
27 gelagert ist und sich andererseits gelenkig an bzw. in der Motorwelle
18 abstützt. Die Art und Weise, wie die Antriebowelle 26 mit der Motorwelle
18 gekupp.#elt und an letzterer abgestützt iatg wird im nachstehenden noch
näher beschrieben. Die Antriebewelle 26 trägt eine /Schnecke 289 die
mit einem Sohneckenrad 29 zuammenarbeitet. Das
Die Scheibe 38 dämpft in Betriebe der Verrichtung die Geräuscheg die .durch die Gelenkverbindung der beiden Wellen enstehen können.The disk 38 attenuates the noise during operations that can arise through the articulated connection of the two shafts.
In Pig. 2 der Zeichnung ist eine Variante dieser Gelenkverbindung dargestellt. Bei dieser Ausführung ist die Stirnbohrung 34 in die-Antriebowelle 26 eingearbeitet, während der Ringwulat 35 an der Motorwelle 18 sitzt. Letztere ist mit der Antriebswelle 26 Über eine Sohraubenfeder 40 verbundene die die Enden der beiden fellen umschlingt. Beirt Anlaufen der Motorwelle 18 zieht sich die Schräubenfeder 40 zunächat an beiden Wellen fest, um dann die Antriebswelle schltVCe mit der Motorwelle zu kuppeln. Diese Ausführung hat den Vorteil, daß der Motor zunächst nur seinen eigenen Anlaufwiderstand zu überwinden bruucht und. erst nfUch dem Festziehen der Schraubenfeder. das gesamte von ihm geforderte Lastmoment aufbrin.--en muß" 4w) Bei der Variante nach-Fig'. 3 sind die beiden 1-d'ellen 189 26 über eine innen gerändelte Hülee 42 miteinander gekuppelt, die über außen gerändeite Abschnitte 43 und 44 der beiden Wellen geschoben ist. Der zur gelenkigen Abstlitzung dienende Ringwulat 35 sitzt hier an einem Stü-tozapfen 45, der sich an den gerändelten Abschnitt 44 der Antriebewelle 26 anschließt.In Pig. 2 of the drawing shows a variant of this articulated connection. In this embodiment, the end bore 34 is machined into the drive shaft 26 , while the annular bead 35 is seated on the motor shaft 18. The latter is connected to the drive shaft 26 via a screw spring 40 which wraps around the ends of the two skins. When the motor shaft 18 starts up, the helical spring 40 is first tightened on both shafts in order to then couple the drive shaft to the motor shaft. This design has the advantage that the motor initially only needs to overcome its own starting resistance and. only after tightening the coil spring. apply the entire load torque required by him - en must "4w) In the variant according to Fig. 3 , the two 1-dellings 189 26 are coupled to one another via an internally knurled sleeve 42, which are connected via externally knurled sections 43 and 44 of the two shafts. The annular bulge 35 serving for the articulated spacing is seated here on a support pin 45 which adjoins the knurled section 44 of the drive shaft 26 .
Bui der Gelenkverbindung nach Fig. 4 sitzt der hingwulat 35 an der Motorwelle 18, während die den Ringwalst aufnehmende Stirnbohrung durch eine auf die A.ntriebewelle 26 aufgepreßte, ein Stück weit über deren Stirnseite hervorstehende Buchse 48 gebildet ist. Die Motorwelle 18 weist mehrere Klauen 49 auig die durch tangentialen Anprägen der Motorwelle gebildet sind. Die Klauen 49 greifen mit Spiel in Ochlitze 50 am Stirnende der Buchse 48 eine so daß die beiden Wellen di,F-,hfe.#i-t. jerloch gelenkig miteinander verbunden sind.4, the hingwulat 35 sits on the motor shaft 18, while the end bore receiving the ring bead is formed by a bushing 48 which protrudes a little beyond the end face and is pressed onto the drive shaft 26. The motor shaft 18 also has several claws 49 which are formed by tangential stamping of the motor shaft. The claws 49 grip with play in Ochlitze 50 at the front end of the bushing 48 so that the two shafts di, F-, hfe. # It. jerloch are articulated together.
Anstelle einen Ringwulsteh mit balliger Mantelfläche könnte die eine Welle auch einen-Hingwulat mit söhmaleiZe s.B. l#big-i#5 breiter ' zylindriecher Manteilflän'he, habeng die mindietens tü einer Seite über eine«n kogelig steh verjüngenden *b40haltt den Ringwuleten In die Mantelflm.che der Welle übergehen kann.Instead of an annular bulge with a spherical outer surface, one of the shafts could also have an angular bulge with a söhmaleiZe sB l # big-i # 5 wider ' cylindric-scented portion flän'he, at least on one side over a n spherical standing tapering * b40 holds the annular bulge in the Shell surface of the shaft can pass over.
