Patent ID: 8627940

Claim:
A drive system for an installation for a passenger transport, including an escalator or a moving walkway, having steps or pallets, the drive system comprising: pulling elements comprised of plate link chains having bushes and rolls adapted to be actively connected to the steps or pallets and moved in a transport direction; and at least one electric motor operatively connected to a gear train having a chain wheel and arranged in a reversing area of the transport and at least one further electric motor interacting with a gear train having a chain wheel including teeth separated by tooth grounds and arranged in a transport path to exclusively serve for a linear motion of the transport, at least some of the electric motors and gear trains in the transport path having approximately the same power, wherein the electric motor containing the gear train and positioned in one of the reversing areas of the transport and the at least one further electric motor exclusively serving for the linear motion of the transport are arranged so that the bushes/rolls of the plate link chains are adjacent to or roll along individual teeth of the chain wheel while only getting into line contact, outside the tooth ground of the chain wheel, and that a point of force application of the cylinder bushes/rolls on the respective tooth of the chain wheel is realized so that only a one-directional force application component is generated at the respective tooth, wherein each chain wheel includes at least one shoulder in the area of its teeth that supports individual plates in a radial direction of the respective plate link chain when the plate link chain runs through the chain wheel.
