摘要:
Device for the passenger transport, in particular an escalator provided with steps or a moving walkway equipped with pallets, wherein the steps or pallets are connected to each other to form a continuous step or pallet belt and can be moved in the direction of transport by means of drive elements, wherein a lower entrance or exit section of the device is connected to an upper exit or entrance section via at least one arched transport section which, seen over the length and height thereof, is formed by different radii which verge into each other, wherein at least the arched transport section is composed of several linear framing sections which are connected to each other in the region of the facing ends thereof.
摘要:
A device for connecting a chain, which is actively connected to a roller, to a step or a pallet of an escalator or a moving walkway, respectively. The chain has a roller side and a step or pallet side. The device includes a hollow stud disposed on the roller side and a cylindrical shoulder disposed on the step or pallet side. The hollow stud has a clearance to receive the cylindrical shoulder. A slide bearing is arranged at least radially between a circumferential surface of the hollow stud defining the clearance and an outer circumferential surface of the shoulder.

The invention relates to an escalator or moving walkway that includes a drive shaft rotating at a relatively low peripheral speed around a horizontal axis and at least one sealing element associated with the drive shaft. Lubricant is supplied to the drive shaft and can escape from leakages at the one sealing element. A device is provided for a permanent recirculation of the lubricant escaping from the leakages. The device includes at least one conveyor element arranged downstream of the sealing element, seen in the direction of the leakage, and at least one recirculation element for the lubricant. The recirculation element cooperates with the conveyor element to return the lubricant into a region upstream of the at least one sealing element.

A safety device for people movers, particularly for escalators and moving sidewalks, includes at least one carrier plate supporting a comb segment at a first end. The carrier plate is horizontally displaceable relative to at least one carrier element which accommodates the carrier plate, and is pivotable about a horizontal rotational axis which is located at a second end of the carrier plate and cooperates with at least one switch-off device for immobilizing the people mover.
摘要:
A drive system for transport of a passenger transport installation including an escalator or a moving walkway. Steps or pallets of the transport are actively connected to pulling elements which can be moved in the transport direction by at least one electric motor provided with a gear train having a chain wheel. The electric motor containing the gear train is positioned in one of the reversing areas of the transport and a further electric motor exclusively serves for the linear motion of the transport. Bushes/rolls of 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. A point of force application of the bushes/rolls on the respective tooth of the chain wheel is realized such that only a one-directional force application component is generated at the respective tooth.

A sealing system for fast-running motors with a directly flanged-on gear unit, used for passenger conveyor systems such as escalators and moving walkways, is provided. The sealing system includes at least one sealing element comprising a radial shaft seal, at least one centrifugal element, at least one cover and suctioning element, and a lubricating oil collection chamber. The lubricating oil collection chamber being provided in a region of the centrifugal element and connected via at least one channel that extends in the direction of the cover and suctioning element to a gear unit chamber of the gear unit, the gear unit chamber being located above an oil level in an intake region of the cover and suctioning element. The cover and suctioning element is arranged between the gear unit and the sealing element.

摘要:
A safety device is described for a passenger conveyor system, more particularly an escalator or travelator, that includes a main drive shaft (2) mounting return elements (3) for the transport chains (4) of the steps or pallets, a further shaft containing return elements (3) for the handrails (7) and at least one gear (8, 9, 10) connecting the main drive shaft (2) to the shaft. The drive power of at least one drive unit arranged external to the return elements (3) is translatable via a transport device (12) to the main drive shaft (2). The safety device contains at least one flyweight element (18) provided at the gearing end, at least one brake device (22) as well as at least one control device (14) actuating the brake device (22), and at least one movement/rpm sensor (21) provided in the region of the flyweight element (18) and connected to the control (14), device wherein load-independent braking of the main drive shaft (2) is achievable by the brake device (22) on the basis of signals received from the sensor (21).
