Definitions
- the invention relates to a device for driving components of an escalator or an escalator.
- escalators or moving walks are driven indirectly or directly via electric motors.
- at least one reduction gear is provided, and if necessary, a transfer gear can also be provided, in the area of which the movable components of escalators or moving walkways can be driven together.
- Such components are the step or pallet belt and, if necessary, also the handrail, provided that there are no separate drive means for the same.
- the step or pallet belt is usually moved by means of link chains, which are changed in the direction of travel in the deflection areas via chain wheels provided there.
- An essential requirement for escalators and moving walks is that the step or.
- Pallet belt can be deflected as possible without the undesirable polygon effects and, when the drive is common, the step or pallet belt and the handrail run synchronously with one another, so that one does not lead or lag behind the other component, so that personal injury cannot always be ruled out.
- link chains can be used for the step or pallet belt, which also have a greater division depending on the step or pallet width, for example about 200 or about 400 mm. If necessary, this is in operative connection with a drive motor that runs at a non-constant speed. Under certain circumstances, however, these larger chain divisions, which are desired, bring about what the polygon effect of the deflection and possibly also the synchronous drive of the handrail - problems with it.
- the aim of the subject of the invention is therefore to develop a device for driving components of an escalator or a moving walk in such a way that regardless of the selected chain pitch of the step or. Pallet belt and the existing drive motor in any case, the polygon effect avoided as far as possible and a synchronous run of the associated handrail is ensured with a common drive.
- a device for driving components of an escalator or moving walkway comprising at least one drive motor and at least one gear which is in operative connection with the components, such as a step or pallet chain drive shaft, with at least one pair of gearwheels on the sprocket shaft side is provided with a variable pitch circle diameter.
- a device for driving components of an escalator or a moving walkway comprising at least one drive motor and at least one transmission which is connected to the components, such as a step or pallet sprocket shaft and a handrail drive shaft, in particular the sprocket shaft side at least one gear pair is provided with a variable pitch circle diameter.
- the transmission concept according to the invention is preferably implemented in the area of a transfer case, the required non-uniformity being carried out by means of gear pairs having a variable pitch circle diameter, preferably exclusively on the side of the step or pallet sprocket shaft, while if a handrail drive shaft is present, the same rotates at a constant speed.
- the pitch circle diameter fluctuates between a minimum and a maximum value as many times on the circumference as the associated sprocket for the drive chain of the step or pallet belt has teeth.
- Figure 1 schematic diagram of an escalator drive, including a combinable step and handrail drive
- FIG. 2 schematic diagram of a moving walkway drive, in particular for the
- Figure 1 shows a transfer case 1 for an escalator, not shown.
- a merely indicated drive 2 consisting of a motor and, if necessary, a reduction gear.
- gearwheels 3, 4, 5, 6 are provided, whereby the gears 4 and 5 act on the one hand on a step sprocket shaft 7 and on the other hand on a handrail drive shaft 8.
- the step chain wheel-side gear pair 3, 4 is provided with a variable pitch circle diameter 9, 10, the variable pitch circle diameter 9, 10 fluctuating between a minimum and a maximum value on the circumference, in such a way that the chain wheel (not shown further) has teeth.
- the gear pair 3, 4 then generates a defined non-uniformity only on the side of the step sprocket shaft 7, while the speed of the handrail drive shaft 8 remains constant.
- This drive concept is preferably used when an increased chain pitch (depending on the step width) of, for example, 200 or 400 mm is used, which makes a different kind of compensation of the polygon effect necessary in the case of non-uniform drive speed of the drive motor 2, in order to nevertheless ensure synchronism between step or Bring the sprocket shaft 7 and handrail drive shaft 8.
- the schematic diagram according to FIG. 2 shows a transmission 1 'in operative connection with a drive motor 2' for use in a moving walkway, not shown.
- Gearwheels 3 ', 4' are arranged within the transmission 1 ', the gearwheel 4' forming the output in the direction of a pallet sprocket shaft 7 '.
- the pair of gearwheels 3 ′, 4 ′ on the pallet sprocket side is provided with a variable pitch circle diameter 9 ′, 10 ′ in analogy to FIG. 1.
