Definitions
- the present invention relates to a drive for an escalator, comprising at least one wave.
- a drive of the aforementioned type is known from DE 697 16 584 T2 known.
- the drive described in this document includes a motor on which a drive gear is arranged.
- On the A drive chain is held around the circumference of the drive gear around a coaxial to the drive gear on a shaft Gear runs.
- There are sprockets for one on this shaft Conveyor track arranged in one for escalators or moving walks is constructed in a known manner.
- the conveyor track is with conveyor chains provided that revolve around the sprockets. At this The conveyor chains are arranged by the sprockets driven and redirected around it at the same time. The conveyor chains are fed tangentially to the sprockets. This will point the conveyor chains and the sprockets when the Sprockets different in the respective conveyor chain Speeds up, causing bumps toward the free running part of the conveyor chains comes.
- the drive and the deflection of the conveyor chain by means of a Chain gear occurring polygon and recirculation effects negatively affect the smooth running of the escalator in particular.
- the polygon and circulation effects lead to high loads on the conveyor chains, the sprockets and the drive.
- the polygon and orbital effects increase Increase in conveyor speed of the escalator.
- Farther escalators driven in this way require a large installation space, to accommodate all the necessary components of the drive can.
- Differences in height serve, as in multi-storey department stores is provided, due to the installation depth of the escalator and corresponding ceiling heights of the associated drive to be provided in order to be able to install the escalator.
- the object of the present invention is to provide a drive for a To provide escalator, the space-saving installation of the Escalator enables and to reduce the polygon and Contributes to circulation effects.
- the shaft at least is designed in sections like a snail.
- the usage an at least partially designed like a snail Shaft for transferring a feed movement to the one to be driven
- Components of the escalator contribute to a reduction in the number of Deflection devices and the components to be driven occurring polygon and circulation effects.
- the Deflection devices have a substantially equal speed on how to drive the components of the escalator.
- the deflection devices of the driven components of the escalator are driven.
- the components of the escalator are driven by the shaft, which is a substantially constant speed on the Components of the escalator transfers, the inventive Drive higher conveyor speeds and an increase in Allows chain splitting without the polygon and wrap effects strengthen.
- Conveyor speed of the escalator can be greater than 0.5 m / s his.
- the shaft can be designed as a worm shaft.
- the shaft can preferably extend in the longitudinal direction of the escalator extend.
- the shaft is preferably arranged below of the accessible walk-in area of the escalator between the deflection devices. This makes the dimensions the machine rooms at the end of the escalator present invention, which in conventional escalators Housing one or more engines that Deflection devices and the drive means are used, smaller than required in the prior art.
- Arrangement of the shaft help increase the depth of the escalator reduce, resulting in a space-saving installation of the escalator is possible.
- the shaft can preferably be designed as a shaft with a helical helix welded onto it. Furthermore, the shaft can be designed as a shaft with a groove turned helically out of the shaft. Likewise, the manufacture of the shaft with such a turn can be carried out by milling or other suitable manufacturing processes. Furthermore, the shaft can be connected directly or indirectly to a motor. In this way, existing spatial and structural framework conditions can be better taken into account and used, under which the escalator is to be installed.
- the escalator can preferably have at least one funding include that can be driven by the shaft.
- the Funding is used to transfer the feed movement to the components of the escalator to be driven.
- it can Funding can be carried out substantially chain-like, the Funding in particular as an endless chain around deflection devices can be arranged circumferentially.
- the funding can be articulated Include chain links, the chain links releasably together can be connected. This will make the Funding increases, because in this way individual chain links of the funding replaced.
- the Chain links are essentially cranked.
- a plurality of chain links or each of the Chain links each have at least one feed means.
- the feed means can be detachably arranged on the chain link, what the simple exchange of individual feed means in Repairs allowed.
- the feed means on the Winding of the shaft facing side of the chain link arranged be, where it can be engaged with the turn.
- Farther can have a stair plate that can be swiveled around the axis be arranged.
- the stair plate can accommodate up to serve transporting persons and / or objects.
- At least two feed means can advantageously be used at the same time mesh with the shaft. Is that for example Feed means of a chain link on the last turn in Direction of conveyance of the shaft, this is at the same time Feed means of the subsequent chain link essentially in the middle of the shaft and is engaged with its winding.
- the drive can preferably be at least two parallel to one another arranged, at least partially snail-like waves exhibit.
- the waves each drive a subsidy, which are also arranged parallel to each other.
- One is in particular Device for synchronizing the drive provided to the Waves transmit the same torque and the same time The waves start up when the escalator is put into operation guarantee.
- the drive can advantageously be at least two in a row Row arranged, at least in sections snail-like Have shafts that are each connected to a motor. Consequently can apply greater torque from the waves to the escalator be transmitted. This is beneficial for escalators with which larger distances should be overcome, such as this when using moving walkways at airports.
- the turns can be parallel to each other arranged waves to be executed in opposite ascending order.
- the shafts arranged parallel to each other can pass through the Stair plates must be connected to each other.
- By using it one with a left-handed and one with a right-handed Winding wave will be the most on the funding acting transverse forces on the between the funds arranged stair plates transferred.
- the on the stair plates Transmitted lateral forces are opposite to each other and largely compensate each other. This helps increase The escalator runs smoothly.
- the escalator can preferably be used as an escalator or as a moving walkway be executed.
- the drive according to the invention Use with escalators used for the transportation of people or find moving walkways. For escalators for the promotion of people stands next to a high conveying speed Escalator the smooth running in the foreground. These requirements can be fulfilled by the drive according to the invention.
- the representation is the part of an escalator drive essential to the invention, especially for the drive of an escalator or one Escalator is provided.
- the escalator drive includes at least one with a helical turn Shaft, in particular a worm shaft 1, and at least one funding driven by the worm shaft 1 2.
