- the rotating part 16 indicates one end a cylindrical extension 24, on which the mark 12 is applied, on.
- At the other end of the rotating Part 16 is a cylinder 21 and to this cylinder 21st subsequent collar 20 is arranged.
- the cylinder 21 is in pushed the inner ring 14 of the bearing 13, wherein the insertion depth is defined by the collar 20.
- the penetration depth is low to the support force transmission from the camp 13th not significantly affect the motor shaft 15.
- This solution allows a cost-effective, space-saving and Exact arrangement of a signal generator 17 in the drive 1.
- the assembly the drive 1 is easily possible.
- the fixed part 18 of the signal generator 17 is fastened by means of a spring plate 26 in the housing of the motor 4.
- the signal generator 17 can be held in its position with little force, and he can also avoid a touch. This may be necessary if the rotating part 16 of the signal generator 17 does not rotate absolutely centric.
- the drive 1 consists in a preferred embodiment of two spaced apart blowing zones 3, wherein a blowing zone 3, one or more traction sheaves 2 may include.
- the motor 4 and / or a brake 5 are arranged outside the two blowing zones 3, and a main bearing 25 is arranged between the two blowing zones 3, so that a main supporting force of the, generated by the support and drive belt 6, carrying capacity, essentially, means the main bearing 25 is introduced into a support structure.
- the drive can be made compact and inexpensive.
- belts as carrying and propellant 6.
- Trag- and drive belt 6 allow the use of small pulley diameters.
- a drive 1 with correspondingly high speeds and low torques can be used, which in turn allows the use of drives with small dimensions.
- the belts are flat according to the design of the traction sheave 2, that is smooth, or they have a longitudinal profiling, for example in the form of V-ribs or they have a transverse profile, for example a tooth shape.
- the motor shaft 15, Drive shaft 7 and traction sheave 2 made in one piece.
- the motor shaft 15 and the drive shaft 7 be made in one piece, or the drive shaft 7 and the traction sheave 2 are made in one piece.
- the production as individual separate parts is of course possible. The choice of the suitable embodiment is at the manufacturer's option.
- An advantageous embodiment of the drive arranges a level adjustment 28 on the drive 1.
- the level adjustment 28 takes over forces which arise due to unbalanced load-bearing forces.
- this level adjustment 28 is mounted in the vicinity of the support bearing 13.
- a mounted in the housing of the drive 1 spirit level 29 simplifies the control of the setting.
- the arrangement of the support bearing 13 at the motor end of the drive shaft 7, and the motor shaft 15, allows optimal introduction of supporting forces in the building.
- the bearing 13 thus serves the precise guidance of the signal generator 17, it takes over the supporting forces which arise as a result of asymmetrical force introduction at the main bearing 25 and directs these forces preferably directly by means of the level adjustment 28 in the support structure, or in the building.
- the signal transmitter be arranged at each end of a shaft, as in a Pulley or a speed limiter with appropriate Bearing design or the inner ring 14 and the rotating part 16 of the signal generator 17 may be in one piece be executed.

Abstract
Description
Motor, Bremse und Treibscheibe sind dementsprechend Kräfte- und Momentenwirksam miteinander verbunden.
Ein kostengünstiger Anbau eines Signalgebers soll bereitgestellt werden und der Antrieb als gesamtes soll geringe äussere Abmessungen aufweisen.
Vorteilhafterweise ist die Marke, bzw. die Codierung an einem rotierenden Teil angebracht, in diesen integriert oder dazu verbunden, wobei der rotierende Teil zugleich den Innenring des Lagers fixiert. Eine separate Befestigung des Lagers erübrigt sich dadurch. Dies ermöglicht eine Reduktion der Anzahl benötigter Teile und reduziert damit die Kosten des Antriebes.
- Fig. 1:
- Beispiel eines ausgeführten erfindungsgemässen Antriebes
- Fig. 2:
- Beispiel einer Anordnung eines Signalgebers
Damit kann der Signalgeber 17 mit geringer Kraft in seiner Position gehalten werden, und er kann zugleich bei einer Berührung ausweichen. Dies kann erforderlich sein wenn der rotierende Teil 16 des Signalgebers 17 nicht absolut zentrisch dreht.
Damit ist eine direkte und optimale Einleitung der Tragkräfte des Antriebes 1 in eine Tragstruktur ermöglicht. Der Antrieb kann dadurch kompakt gebaut und kostengünstig ausgeführt werden.
Die Riemen sind dabei entsprechend der Ausführung der Treibscheibe 2 flach, das heisst glatt, oder sie weisen eine Längsprofilierung, beispielsweise in der Form von Keilrippen auf oder sie weisen ein Querprofil, beispielsweise eine Zahnform auf.
Das Lager 13 dient somit der genauen Führung des Signalgebers 17, es übernimmt die Stützkräfte welche infolge unsymmetrischer Krafteinleitung beim Hauptlager 25 entstehen und leitet diese Kräfte vorzugsweise direkt mittels der Niveaueinstellung 28 in die Tragstruktur, bzw. in das Gebäude ein.
