Definitions

  • the invention relates to an escalator or moving walk, according to the preamble of claim 1.
  • Moving walks usually have a circumferential pallet belt and Escalators usually have a continuous band of steps, which are each driven with step or pallet chains. It is It is important that the step / pallet chains precisely match their conveying task perceive, while at the same time absorbing considerable loads must be able to. In particular, there must be no essential Lengthening of the chains come in the longitudinal direction, otherwise the Gap between adjacent steps or pallets would increase the allowable dimension.
  • the chain division can basically the step / pallet chain can be enlarged. Indeed the number of teeth of the deflection wheel for the Drive of the step / pallet chain can be reduced because of the The available installation space is usually on-site, i.e. from the side of customers of escalator and moving walk manufacturers.
  • the reduction in the number of teeth increases the so-called polygon effect caused by the non-uniform Speed when running up from individual chain links existing chain on the gear arises.
  • the polygon effect directs longitudinal vibrations into the drive train and especially in the step / pallet chain, which not only the Give passengers a feeling of insecurity, but in particular significantly increase the wear so that the desired Effect is reversed.
  • the invention is therefore based on the object of an escalator or a moving walk according to the preamble of claim 1 create that despite the use of step / pallet chains enables a drive in which the polygon effect is at least reduced and yet a chain with enlarged Chain pitch and small number of teeth of the deflection wheel can be used is. As a result, the chain is much cheaper manufactured and / or the installation space of the escalator / moving walk can be significantly reduced.
  • the solution according to the invention allows the polygon effect a corresponding design of a countershaft transmission compensate.
  • a drive chain is provided, which between Drive wheel and countershaft sprocket rotates.
  • the drive wheel, the rotatably connected to the guide wheel of the step / pallet chain is to be specially designed so that it passes through the lay chain a polygon effect opposite to the step / pallet chain has, so that the two polygon effects against each other cancel.
  • This solution has the particular advantage that the drive train itself is vibration-free, so that the Wear is significantly reduced.
  • the chain pitch is greatly increased. hereby are considered on the longitudinal extent of the step or Pallet belt per level or pallet significantly fewer chain links and intermediate bearing bolts and bearing sleeves required, so that the chain can be manufactured more cost-effectively can. Also, the number of possible places where elongation of the chain can take place reduced. Per bearing pin is therefore in such a modified work chain greater chain elongation allowed, so the maintenance intervals and the life of the chain can be increased. Furthermore, the deflection wheel in the Diameter can be reduced so that the entire installation space of the Escalator / moving walk can be reduced.
  • the countershaft sprocket can have an elliptical shape have and essentially with constant angular velocity circulate. This allows an inexpensive drive motor be used in an energetically favorable manner with constant Rotational speed can be driven.
  • a elliptical form creates a sine curve, the chain line curve the step / pallet chain speed when running can compensate almost completely on the deflection wheel.
  • An escalator according to the invention has a step chain 10, which is deflected at the end via a driven deflection wheel 12 becomes.
  • the deflection wheel which is shown schematically here, points only 5 teeth 14, between which there are indentations 16 extend for the reception of roles.
  • the step chain points quite long chain links 20, and because of the small The number of teeth of only 5 teeth is the diameter of the Deflection wheel 12 small, so that the available installation space is sufficient but without the measures according to the invention a substantial one would be Expected polygon effect.
  • a drive wheel 22 is connected in a rotationally fixed manner to the deflection wheel 12 provided that in a conventional manner on the same shaft is stored.
  • the drive wheel 22 is part of a countershaft transmission 24, of a countershaft chain 26 and a countershaft sprocket 28, which rotatably with a drive motor, not shown the escalator is connected.
  • the transmission chain 26 also guided over a deflection pinion 30, and their dreams 32nd and 34 extend substantially parallel to one another from the drive wheel 22 away.
  • the step chain 10 is preferably on the inlet side and outlet side guided on rails, the transverse vibrations of the step chain prevent.
  • 1 and 2 is the shape and orientation of the drive wheel 22 to the deflection wheel 12 selected that the polygon effect is compensated for if possible.
  • the polygon effect stems from that during chain transport changing effective radius. This is the example of 1 shown in Fig. 1 and that shown in Fig. 2 36 ° position explained.
  • the effective radius for chain transport in the deflection wheel 12 is in the 0 ° position according to Fig. 1 R '. If the deflection wheel 12 is half a tooth angle, So turned 36 °, the effective radius is only R.
  • the chain speed of the step chain 10 accordingly fluctuates when turning the deflection wheel 12 with constant Drive speed by the difference between R 'and R.
  • the drive wheel 22 is provided for this purpose to give appropriate form. Basically, this would be a corresponding one Shaping also possible with the counter pinion 28, wherein the embodiment according to FIGS. 1 and 2 preferably a corresponding one Shaping for the drive wheel 22 provides and thus changes in speed in the lay chain 26 avoids.
  • the deflection wheel is implemented with 11 teeth is. This results in an odd number of teeth, the required diameter of the deflection wheel 12 not much larger than a four-tooth pulley is. Due to the odd number of teeth, the tensioning wheel 30 only has to make small movements.
  • FIG. 3 Another embodiment of the solution according to the invention is 3 can be seen from FIG.
  • this solution there are 5 teeth and corresponding ones Indentations 16 are provided for the deflection wheel 12, see above that there are quite long chain links 20.
  • the compensation the polygon effect is achieved with a special solution Shaping of the countershaft gear 28.
  • dreams 32 and 34 are substantially parallel to each other when they emerge from the drive wheel 22.
  • the counter gear 28 has a polygon shape.
