Abstract

The invention relates to a method for guiding a drive chain containing links, guide rolls and connecting elements in the area of a reversing device, which is formed by a chain wheel, of a pedestrian conveyor system, particularly of an escalator or a moving sidewalk, whereby the guide rolls are supported, at least on the chain wheel side, on a guide profile. In drive chains of this type, which have connecting elements in the coupling areas of the links and in which a guide roll mounted between the links is provided in the remaining free space, the drive chain is led into the chain wheel such that when viewed in a moving direction the front connecting element of each link element is firstly placed in an associated accommodating area and the guide roll is subsequently placed in a corresponding calotte, and the rear connecting element is firstly led into the associated accommodating area when the guide roll is supported in the calotte in an elastically damped manner.

Description

technical field

[0001] The invention relates to a method for guiding a drive chain consisting of chain plates, guide rollers and connecting elements in the region of a slewing device consisting of sprockets of a pedestrian conveyor system, in particular an escalator or a moving walkway, wherein the guide The roller is supported on the guide profile at least on the sprocket side. Background technique

[0002] During the slewing of the pedestrian conveyor drive chain through the slewing device including the sprockets, undesired polygonal and slewing effects occur which adversely affect the quiet operation of the pedestrian conveyor. The polygon effect is caused by the chain polygons being supported on the sprockets. As the angle of rotation increases, the effective radius of the sprocket changes, so the speed of the chain fluctuates between maximum and minimum values. The chain rollers and sprocket teeth have different speeds when meshing with the sprocket, thus causing coll...
