Definitions
- the invention relates to a people conveyor drive.
- the invention further relates to a people conveyor comprising such people conveyor drive.
- People conveyors such as escalators, moving walkways, moving sidewalks, etc. are widely used these days to effectively transport passengers from one location to another. Areas of usage of these people conveyors may include airports, hotels, shopping malls, museums, railway stations and other public buildings.
- Such people conveyors typically have two landings (e.g., a top landing and a bottom landing in case of an escalator) and a plurality of treads, such as steps or pallets, interconnected to form an endless tread band extending in a longitudinal conveyance direction.
- the endless tread band is driven by a tension member drive system comprising an endless tread drive tension member, e.g. a tread drive belt or a tread drive chain.
- An exemplary embodiment of the invention relates to a people conveyor drive of a people conveyor comprising a plurality of treads interconnected to form an endless tread band.
- the people conveyor drive comprises a tension member drive system configured for driving the tread band, and a shaft having a shaft main portion and at least one shaft support portion, the at least one shaft support portion being supported by at least one shaft bearing to be rotatable around a shaft axis.
- the shaft is configured for engaging with an endless tread drive tension member, in particular for driving the endless tread band.
- the shaft has a split shaft configuration with the shaft main portion being detachably coupled to the at least one shaft support portion.
- US 5 224 580 A discloses a power transmission system for use in a platform drive mechanism of a passenger conveyor which has a conveyor frame and a plurality of laterally extending passenger platforms which are movably supported for driven movement about an endless path on the frame and engaged with a pair of circuitous drive chains disposed on opposite sides of the conveyor frame.
- the transmission system has a multiple stage reduction gear drive positioned outboard of the passenger platforms and directly coupled between the drive chains and a motor for driving the passenger platforms in response to energization of the motor.
- a sprocket assembly has a drive shaft which extends laterally across the conveyor frame and mounts a pair of axially spaced sprockets.
- One of the sprockets is coupled between one axial end of the drive shaft and the gear drive output stage and engages one of the drive chains, and the other of the sprockets engages the second one of the drive chains and is coupled between a second axial end of the drive shaft and a support shaft journaled on the conveyor frame.
- EP 1 020 394 A1 discloses a device and method for simplifying the replacement of bearings on an escalator or moving walkway including a support structure, which has suitably shaped secondary supports on which the chain wheel assemblies of a drive unit are fixed with detachable connectors.
- the central axial supports are fixed detachably on the support structure by screws.
- the central axis of the chain wheel assemblies is shaped so that it slides in the inner rings of the roller bearings of the assemblies so far that these inner rings become accessible.
- an escalator or moving walk has a drive arranged in a reversing area.
- the drive drives chain wheels that move the step band or pallet band and include a motor, an axial gear, a first hollow shaft and a second hollow shaft.
- the motor drives a belt to drive a gear input shaft that runs coaxial to the first hollow shaft.
- Arranged at one end of the gear input shaft is an operating brake; the other end of the gear input shaft is connected to the axial gear.
- a first flange connects a first chain wheel to a truss.
- a second chain wheel is arranged at one end of the second hollow shaft; the other end of the second hollow shaft is connected to the housing of the axial gear.

- the inner drive wheel portion is detachably fixable to the outer drive wheel portion for coupling the shaft main portion to the at least one shaft support portion.
- Such a configuration allows detachably coupling the shaft main portion to the at least one shaft support portion without increasing the diameter of any of the shaft portions. This allows providing a space-saving split shaft configuration, which in particular does not occupy more space than a conventional (non-split) shaft configuration.
