A device for the guidance of an endless belt for escalators or moving walkways in an endless belt of an escalator or a moving walkway, the chain rollers are guided by way of a support rail having a running track and by way of a compensating rail having a running track, and at the entry of a chain wheel, which deflects the endless belt, the chain rollers move from the rectilinear running track of the support rail onto the curved running track of the compensating rail and move from the compensating rail, at a tangent point, into engagement with the chain wheel, with the chain rollers being displaced, towards the chain wheel, by a spacing (h.sub.0), during the movement thereof, from the running track of the support rail to the tangent point, with the spacing being measured transversely to the running direction, in the direction extending at right angles to the running direction, with this displacement having an advantageous effect on the quietness of operation of the endless belt.
A device for the guidance of an endless belt for at least one of escalators and moving walkways comprising one of steps and pallets, of chain links, with the chain links being connected with adjacent chain links by link pins and chain rollers, with the chain rollers being retained by the link pins, with the chain rollers being moved on a running track of a support rail and on a running track of a compensation rail and being deflected by a chain wheel, wherein a the running track of the support rail and the running track of the compensation rail are arranged externally of a tangent to a chain pitch circle of the chain wheel that extends in the running direction of the endless belt, and wherein the running track of the compensating rail is guided, at one end, towards a chain wheel pitch circle.
A device for the guidance of an endless belt for at least one of escalators and moving walkways, the endless belt including a plurality of one of steps and pallets, said device comprising:
